Race-Day Warm-Up for Indoor Rowing

Abstract

Warm-up is the rower's pre-test system for turning the body's stored physiology into the result on the ergometer, and the peer-reviewed literature has converged on a small set of levers that move the first 500 m of severe-intensity rowing and the back half of threshold pieces. The [15] Bishop 2008 warm-up II review placed the warm-up-structure anchor ([15] Bishop 2008, Level 1a). The [1] Concept2 Warm-up governance placed the manufacturer anchor ([1] Concept2, Level 5). The [10] World Rowing indoor rowing discipline governance and [11] World Rowing indoor rules governance placed the international-governance anchor ([10] World Rowing, Level 5; [11] World Rowing, Level 5). The [13] British Rowing Go Row Indoor tests governance placed the federation-coaching anchor ([13] British Rowing, Level 5). The [16] Faulkner 2007 warm-up behaviour study placed the physiological anchor ([16] Faulkner 2007, Level 2b). The [30] Jones 2006 VO2 kinetics review and [31] Burnley 2010 VO2 kinetics primary-studies review placed the oxygen-uptake-kinetics anchor ([30] Jones 2006, Level 1a; [31] Burnley 2010, Level 1a). The [32] Seitz 2016 PAPE meta-analysis and [33] Blazevich 2016 PAPE review placed the post-activation-potentiation anchor ([32] Seitz 2016, Level 1a; [33] Blazevich 2016, Level 1a). The [39] Birrer 2012 psychological-skills-training review and [40] Gould 2002 Olympic-coaches survey placed the mental-prep anchor ([39] Birrer 2012, Level 5; [40] Gould 2002, Level 5). The [59] Sawka 2007 ACSM fluid-replacement position stand and [60] Shirreffs 2011 fluid-and-electrolyte review placed the hydration anchor ([59] Sawka 2007, Level 5; [60] Shirreffs 2011, Level 5). The [55] Thomas 2016 joint ACSM/AND/DC nutrition position stand placed the refuelling anchor ([55] Thomas 2016, Level 5). The [53] Grgic 2019 caffeine umbrella review and [54] Grgic 2021 caffeine meta-analysis update placed the caffeine anchor ([53] Grgic 2019, Level 1a; [54] Grgic 2021, Level 1a). The [79] Mountjoy 2018 IOC RED-S consensus placed the eating-disorder red line ([79] Mountjoy 2018, Level 5). The article below is the framework for race-day warm-up — the premise, warm-up physiology, intensity and duration, specific versus general warm-up, dynamic versus static stretching, race-rhythm rehearsal, mental warm-up and visualisation, post-activation potentiation, settling time, distance-specific templates for 500 m, 2K, 5K, 6K, and 30 min, conditions for heat and indoor environment, drag factor, caffeine, hydration, sodium pre-load, pre-race routine, conditions for test-result comparability, the eating-disorder red line, the limitations of the literature, and the summary in one paragraph.

The premise: warm-up is the cheapest split-second gain in the test

A 2K, 5K, 6K, or 30-minute all-out effort is the most repeatable within-subject measure of endurance capacity on the ergometer when conditions are held constant, and the warm-up is the rower's largest controllable source of variation between two physiologically similar rowers ([41] Cumming 2008, Level 1a; [45] Garland 2005, Level 4; [95] Pageaux 2014, Level 5). The [15] Bishop 2008 warm-up II review placed the warm-up-structure side: warm-up should comprise a general aerobic component, a sport-specific component, and a final high-intensity component, with the duration and intensity scaled to the test distance ([15] Bishop 2008, Level 1a). The [25] Murtagh 2018 rowing-specific load-management review reached the same conclusion from the rowing-context side: indoor rowers benefit from a sport-specific warm-up that primes the legs, the trunk, and the rate caps before a hard piece ([25] Murtagh 2018, Level 1a).

The honest read: warm-up is the cheapest split-second gain on the ergometer. The rower who treats the warm-up as part of the result rather than as a five-minute ritual absorbs the work and arrives at the first stroke ready to push; the rower who treats the warm-up as a delay to the test loses several seconds on the first 500 m to physiology that is still asleep ([1] Concept2, Level 5; [15] Bishop 2008, Level 1a; [16] Faulkner 2007, Level 2b; [30] Jones 2006, Level 1a). For the broader pacing framework, see our negative-splits-and-other-pacing-strategies guide, and for the post-test window, see our post-test-recovery-and-debrief guide.

Warm-up physiology: temperature, oxygen uptake kinetics, muscle temperature

The physiological premise of warm-up is that several body systems transition from rest to exercise more efficiently when they have been primed, and three mechanisms dominate the literature: muscle temperature, oxygen-uptake kinetics, and the post-activation potentiation of the motor units ([15] Bishop 2008, Level 1a; [16] Faulkner 2007, Level 2b; [30] Jones 2006, Level 1a; [31] Burnley 2010, Level 1a; [36] Malatesta 2009, Level 2b). The [16] Faulkner 2007 warm-up behaviour study placed the muscle-temperature and physiological-response side: a structured warm-up raises muscle temperature, lowers the oxygen cost of subsequent work, and accelerates the oxygen-uptake kinetics at the start of exercise ([16] Faulkner 2007, Level 2b). The [48] Hagerman 1984 applied-physiology-of-rowing review reached the same conclusion from the rowing-specific side: the 2K is a synthesis of aerobic and anaerobic energy systems, and the warm-up primes both before the start ([48] Hagerman 1984, Level 5).

The [30] Jones 2006 VO2 kinetics review and [31] Burnley 2010 primary-studies review placed the oxygen-uptake-kinetics side: pulmonary oxygen uptake adjusts slowly to a step change in work, with a mean response time of 30-60 seconds in the unprimed state, and prior exercise or a structured warm-up accelerates this adjustment ([30] Jones 2006, Level 1a; [31] Burnley 2010, Level 1a). The [36] Malatesta 2009 warm-up-and-VO2-kinetics study placed the cycling-side empirical anchor: warm-up accelerates pulmonary VO2 kinetics at the start of exercise, with the magnitude scaling to warm-up intensity ([36] Malatesta 2009, Level 2b). The [29] Ebert 2007 dehydration-performance study reached the same conclusion from the hydration-and-thermoregulation side: dehydration shifts the back half, and a properly hydrated warm-up is a real lever on the second half of the piece ([29] Ebert 2007, Level 2b).

The [26] Castle 2006 cold-environment warm-up study placed the cold-environment anchor: warm-up is more important in cold than thermoneutral conditions, and longer warm-ups in cold environments protect severe-intensity performance ([26] Castle 2006, Level 2b). The [28] Périard 2015 heat-acclimation review reached the same conclusion from the heat-acclimation side: heat acclimation expands plasma volume, lowers resting core temperature, and protects severe-intensity performance in the heat ([28] Périard 2015, Level 1a). The honest read: warm-up is a real lever on physiology across the full temperature range, and the magnitude scales with the cold-side baseline.

Warm-up intensity and duration

The two operational variables in warm-up design are intensity and duration, and the literature has converged on a moderate-intensity component for 5-15 minutes followed by a final high-intensity component for 1-3 minutes, with the duration scaled to the test distance ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b; [18] Andzelm 2014, Level 2b; [25] Murtagh 2018, Level 1a). The [17] Tomaras 2019 warm-up-intensity study placed the higher-intensity-warm-up side: higher-intensity warm-ups produced larger performance gains in a cycling time trial, with no effect on post-warm-up oxygen consumption ([17] Tomaras 2019, Level 2b). The [18] Andzelm 2014 warm-up-duration study reached the same conclusion from the duration side: longer warm-ups produced faster sprint times in trained swimmers; duration is a real lever on severe-intensity performance ([18] Andzelm 2014, Level 2b).

The [20] McGowan 2015 elite-athlete warm-up study placed the elite-practice side: elite athletes use specific and structured warm-up routines, with substantial individual variation in the chosen components, and the median warm-up duration in elite athletes is approximately 25 minutes ([20] McGowan 2015, Level 4). The [19] Behm 2016 acute-effects-of-stretching meta-analysis reached the same conclusion from the specificity side: pre-event stretching protocols should be sport-specific rather than generic, with the largest performance gains in tasks that closely resemble the test ([19] Behm 2016, Level 1a). The operational rule: 5-15 minutes of moderate-intensity work (zone 2, ~60-70 percent of max heart rate) followed by 1-3 minutes of high-intensity work (zone 4-5, near race pace), with the total duration scaled to the test distance.

Specific warm-up versus general warm-up

The literature has converged on specific warm-up as the more effective strategy for severe-intensity rowing, with specific warm-up defined as warm-up that resembles the test activity in movement pattern, rate caps, and muscle groups ([15] Bishop 2008, Level 1a; [23] Young 2002, Level 2b; [25] Murtagh 2018, Level 1a). The [23] Young 2002 priming-and-rate-of-force-development study placed the specific-warm-up side: specific warm-up activity improves rate of force development more than general warm-up, with the specific benefit scaling to the test task ([23] Young 2002, Level 2b). The [15] Bishop 2008 warm-up II review reached the same conclusion from the structure side: warm-up should comprise a general aerobic component, a sport-specific component, and a final high-intensity component, with the sport-specific component priming the rate caps and the muscle groups ([15] Bishop 2008, Level 1a).

The [25] Murtagh 2018 rowing-specific load-management review reached the same conclusion from the rowing-context side: indoor rowers benefit from a sport-specific warm-up that primes the legs, the trunk, and the rate caps before a hard piece, with rowing itself — rather than running, cycling, or dynamic stretching — the optimal sport-specific component ([25] Murtagh 2018, Level 1a). The operational rule: a 5-10 minute general aerobic component on the rower at conversational pace, followed by a sport-specific component of 3-5 minutes at increasing rate caps and increasing intensity, followed by a final high-intensity component of 1-3 minutes at near-race pace. The honest read: the rower who warms up on the rower rather than on a separate machine absorbs the test more efficiently than the rower who warms up on a treadmill or a bike.

Dynamic stretching versus static stretching pre-exercise

The literature has converged on dynamic stretching as the preferred pre-event warm-up component, with static stretching in the pre-event window reducing strength and explosive performance in most task-specific contexts ([19] Behm 2016, Level 1a; [21] Page 2012, Level 5; [22] Simic 2013, Level 1a; [24] Herbert 2011, Level 1a; [34] Behm 2011, Level 1a). The [22] Simic 2013 stretching meta-analysis placed the pre-event-static-stretching side: pre-exercise static stretching reduces strength by ~5.5 percent and explosive performance by ~3 percent in many task-specific contexts ([22] Simic 2013, Level 1a). The [19] Behm 2016 acute-effects-of-stretching meta-analysis reached the same conclusion from the broader-acute-stretching side: acute static stretching reduces strength and explosive performance, with the effect moderated by stretch duration and test specificity ([19] Behm 2016, Level 1a).

The [21] Page 2012 current-concepts-in-stretching review placed the stretching-taxonomy side: the four principal stretching modes are static, dynamic, ballistic, and PNF, with dynamic stretching the preferred pre-event mode and static stretching the preferred post-event mode ([21] Page 2012, Level 5). The [24] Herbert 2011 stretching-Cochrane review reached the same conclusion from the post-event side: stretching does not produce clinically important reductions in post-exercise muscle soreness in most task-specific contexts, so static stretching should be reserved for the post-event window ([24] Herbert 2011, Level 1a). The [34] Behm 2011 static-stretching-and-performance review reached the same conclusion from the moderator side: the static-stretching penalty is moderated by stretch duration, with stretches longer than 60 seconds producing larger deficits ([34] Behm 2011, Level 1a). The operational rule: dynamic mobility work (leg swings, arm circles, hip openers) for 2-3 minutes before the general aerobic warm-up; static stretching reserved for the post-event cooldown.

Race rhythm rehearsal: stroke-by-stroke priming

Race rhythm rehearsal is the rower's sport-specific warm-up component that primes the nervous system, the rate caps, and the stroke quality before the test, and the literature has converged on 3-4 short strokes at increasing rate caps as the practical implementation ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [30] Jones 2006, Level 1a; [31] Burnley 2010, Level 1a; [48] Hagerman 1984, Level 5). The [25] Murtagh 2018 rowing-specific load-management review placed the rowing-context side: indoor rowers benefit from a sport-specific warm-up that primes the legs, the trunk, and the rate caps before a hard piece ([25] Murtagh 2018, Level 1a). The [1] Concept2 Warm-up governance reached the same conclusion from the manufacturer side: priming exercise is a real lever on the first 500 m of a 2K and on the VO2 kinetics of severe-intensity rowing ([1] Concept2, Level 5).

The [48] Hagerman 1984 applied-physiology-of-rowing review placed the rowing-physiology side: the 2K is a synthesis of aerobic and anaerobic energy systems, and the race-rhythm rehearsal primes both before the start ([48] Hagerman 1984, Level 5). The [31] Burnley 2010 VO2-kinetics primary-studies review reached the same conclusion from the priming-mechanism side: prior heavy exercise accelerates VO2 kinetics on a subsequent bout, and the priming effect is real and measurable ([31] Burnley 2010, Level 1a). The operational rule: 3-4 short strokes at increasing rate caps (24-26-28-30 for a 2K, 26-28-30-32 for a 5K) at the end of the warm-up, with 60 seconds of easy rowing between strokes, finishing 3-5 minutes before the start.

Mental warm-up: visualisation, priming, and arousal regulation

Mental warm-up is the rower's psychological pre-test system, and the literature has converged on a four-component framework: imagery, self-talk, arousal regulation, and pre-performance routine ([37] Sheikh 1996, Level 5; [38] Feltz 2013, Level 1a; [39] Birrer 2012, Level 5; [40] Gould 2002, Level 5; [41] Cumming 2008, Level 1a; [42] Weinberg 2008, Level 5; [43] Hanton 2004, Level 5; [44] Eubank 1997, Level 5). The [38] Feltz 2013 imagery meta-analysis placed the imagery side: mental practice combined with physical practice produces larger motor-skill gains than physical practice alone in most task-specific contexts ([38] Feltz 2013, Level 1a). The [41] Cumming 2008 mental-rehearsal meta-analysis reached the same conclusion from the mental-rehearsal side: mental rehearsal alone produces small but real performance gains, and combined with physical practice produces larger gains ([41] Cumming 2008, Level 1a).

The [40] Gould 2002 Olympic-coaches survey placed the coach-discipline side: Olympic coaches consistently identified mental preparation, goal setting, and pre-performance routine as the variables most associated with athlete success ([40] Gould 2002, Level 5). The [39] Birrer 2012 psychological-skills-training review reached the same conclusion from the psychological-skills side: psychological-skills training for sports includes imagery, self-talk, arousal regulation, and pre-performance routines as the four principal levers ([39] Birrer 2012, Level 5). The [43] Hanton 2004 elite-athlete-coping study placed the elite-athlete side: elite athletes use imagery, self-talk, pre-performance routines, and arousal regulation as their primary coping strategies ([43] Hanton 2004, Level 5).

The [37] Sheikh 1996 mental-imagery book chapter placed the imagery-construct side: imagery is a real psychological lever on motor performance, with vividness and controllability the principal moderators ([37] Sheikh 1996, Level 5). The [42] Weinberg 2008 imagery review reached the same conclusion from the meta-analytic side: imagery is a real lever on motor performance, with the largest benefits in tasks that have a strong cognitive component and well-learned performers ([42] Weinberg 2008, Level 5). The [44] Eubank 1997 mental-preparation review placed the mental-preparation-framework side: mental preparation for sport includes imagery, self-talk, arousal regulation, and pre-performance routines as the four principal levers ([44] Eubank 1997, Level 5). The operational rule: 2-3 minutes of mental rehearsal of the race plan (pacing, rate caps, finish), a brief arousal-regulation breath (4-7-8 or box breath), and the pre-performance routine written down on the monitor or on a card.

Time between warm-up and event: settling time

Settling time is the rower's pre-start buffer between the final high-intensity warm-up rep and the start of the test, and the literature has converged on 3-5 minutes for short pieces (500 m, 2K) and 4-5 minutes for longer pieces (5K, 6K, 30 min) ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b; [18] Andzelm 2014, Level 2b). The [15] Bishop 2008 warm-up II review placed the settling-time side: the duration between the final high-intensity component and the start of the test should be 3-5 minutes, with the rower returning to conversational pace during the settling window ([15] Bishop 2008, Level 1a). The [17] Tomaras 2019 warm-up-intensity study reached the same conclusion from the cycling-time-trial side: settling times longer than 5 minutes did not produce larger performance gains, and settling times shorter than 2 minutes did not allow adequate physiological recovery from the warm-up ([17] Tomaras 2019, Level 2b).

The [18] Andzelm 2014 warm-up-duration study reached the same conclusion from the duration side: warm-up duration interacts with settling time, and longer warm-ups require longer settling times to allow the elevated heart rate and ventilation to return to a sustainable level before the start ([18] Andzelm 2014, Level 2b). The operational rule: finish the final high-intensity rep 3-5 minutes before the start, drop to conversational pace (zone 1-2) during the settling window, and use the final 60 seconds for the pre-performance routine (mental rehearsal, breath, rate-cap confirmation). The honest read: the rower who finishes the warm-up too close to the start loses the settling window; the rower who finishes too early loses the warm-up effect.

Post-activation potentiation / performance enhancement (PAPE)

Post-activation performance enhancement is the rower's conditioning-contraction lever on severe-intensity performance, and the literature has converged on a small but real effect that scales with athlete strength and with the conditioning-contraction specificity ([32] Seitz 2016, Level 1a; [33] Blazevich 2016, Level 1a; [34] Behm 2017, Level 1a; [35] Wilk 2020, Level 1a; [36] Malatesta 2009, Level 2b). The [32] Seitz 2016 PAPE meta-analysis placed the PAPE-ergogenic side: post-activation performance enhancement is a real but small effect on explosive and sprint performance, with the largest benefit in stronger athletes and in tasks that resemble the conditioning contraction ([32] Seitz 2016, Level 1a). The [33] Blazevich 2016 PAPE review reached the same conclusion from the PAP-versus-PAPE side: post-activation performance enhancement (conditioning contractions 5-10 minutes before a sprint) improves subsequent sprint performance by a small but real lever, and the older post-activation potentiation (PAP) construct has been superseded by the broader PAPE framework ([33] Blazevich 2016, Level 1a).

The [34] Behm 2017 PAP review placed the rowing-applicability side: the conditioning contraction in rowing is a 3-5 second near-maximal stroke at the end of the warm-up, followed by a 5-10 minute settling window, and the PAPE effect transfers to severe-intensity rowing in most task-specific contexts ([34] Behm 2017, Level 1a). The [35] Wilk 2020 PAPE-combat-sports review reached the same conclusion from the cross-sport side: the conditioning contraction followed by a short rest is a real lever on sprint and severe-intensity performance across many sports ([35] Wilk 2020, Level 1a). The [36] Malatesta 2009 warm-up-and-VO2-kinetics study placed the VO2-kinetics-interaction side: the PAPE effect and the VO2-kinetics acceleration are complementary, and a properly structured warm-up captures both ([36] Malatesta 2009, Level 2b). The operational rule: 1-3 near-maximal strokes at the end of the warm-up, with 5-10 minutes of settling before the start, and the rower who is well-trained benefits more than the rower who is less-trained.

Warm-up degradation: how long the warm-up effect lasts

The warm-up effect is not infinite, and the literature has converged on a degradation window of 30-45 minutes from the end of the warm-up to the start of the test, with substantial individual variation ([15] Bishop 2008, Level 1a; [16] Faulkner 2007, Level 2b; [17] Tomaras 2019, Level 2b; [18] Andzelm 2014, Level 2b). The [15] Bishop 2008 warm-up II review placed the warm-up-degradation side: the warm-up effect degrades over 30-45 minutes, and a settling window longer than 10 minutes requires a brief re-warm-up at near-race pace to restore the priming effect ([15] Bishop 2008, Level 1a). The [16] Faulkner 2007 warm-up behaviour study reached the same conclusion from the physiological side: muscle temperature, oxygen-uptake kinetics, and motor-unit priming all degrade over 30-45 minutes, with substantial individual variation in the rate of degradation ([16] Faulkner 2007, Level 2b).

The [17] Tomaras 2019 warm-up-intensity study placed the intensity-interaction side: higher-intensity warm-ups produce longer-lasting priming effects, and the rower who finishes the warm-up at near-race pace retains the priming effect longer than the rower who finishes at conversational pace ([17] Tomaras 2019, Level 2b). The [18] Andzelm 2014 warm-up-duration study reached the same conclusion from the duration-interaction side: longer warm-ups produce longer-lasting priming effects, but the warm-up duration and the settling time must be balanced to avoid over-priming ([18] Andzelm 2014, Level 2b). The operational rule: if the settling window is longer than 10 minutes, include a 30-60 second near-race-pace rep 3-5 minutes before the start to restore the priming effect.

Distance-specific warm-up: 500 m, 2K, 5K, 6K, 30 min

The warm-up scales to the test distance, and the literature has converged on a tiered framework: shorter warm-ups for shorter pieces, longer warm-ups for longer pieces, and a sport-specific plus final high-intensity component scaled to the test energy system ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b; [18] Andzelm 2014, Level 2b; [25] Murtagh 2018, Level 1a; [45] Garland 2005, Level 4; [46] Astridge 2024, Level 2b; [47] Ingham 2002, Level 2b; [48] Hagerman 1984, Level 5). The [45] Garland 2005 elite-2K pacing-profile study placed the empirical-shape side: the empirical 2K profile is reverse-J, with a fast first 500 m, a slowest third 500 m, and a small finishing lift, and the warm-up must rehearse the first 500 m ([45] Garland 2005, Level 4). The [46] Astridge 2024 cross-distance pacing study reached the same conclusion from the cross-distance side: 2000 m pacing differs from 1500 m pacing in shape and in the relative weight of the end-spurt, and the warm-up must rehearse the distance-specific shape ([46] Astridge 2024, Level 2b).

The [47] Ingham 2002 2K-determinants study placed the physiology-ceiling side: power at VO2max, VO2max, lactate threshold, and maximal power together explain 98% of 2K variance in elite rowers, and the warm-up must prime each of these systems ([47] Ingham 2002, Level 2b). The [48] Hagerman 1984 applied-physiology-of-rowing review reached the same conclusion from the rowing-physiology side: the 2K is a synthesis of aerobic and anaerobic energy systems, and the warm-up primes both before the start ([48] Hagerman 1984, Level 5). The operational rule for distance-specific warm-up: short pieces (500 m, 2K) require shorter warm-ups with a larger anaerobic component; longer pieces (5K, 6K, 30 min) require longer warm-ups with a larger aerobic component and a longer settling window.

Conditions: heat, cold, indoor temperature, fan use, humidity

Race-day conditions shift the warm-up prescription, and the literature has converged on four conditions: heat, cold, indoor temperature, and humidity ([26] Castle 2006, Level 2b; [27] Racinais 2015, Level 5; [28] Périard 2015, Level 1a; [29] Ebert 2007, Level 2b; [61] EFSA 2010, Level 5; [81] Sundgot-Borgen 2004, Level 4). The [26] Castle 2006 cold-environment warm-up study placed the cold-environment side: warm-up is more important in cold than thermoneutral conditions, and longer warm-ups in cold environments protect severe-intensity performance ([26] Castle 2006, Level 2b). The [27] Racinais 2015 heat-acclimatisation consensus reached the same conclusion from the heat-acclimatisation side: pre-cooling, hydration, and acclimatisation protect performance in the heat ([27] Racinais 2015, Level 5).

The [28] Périard 2015 heat-acclimation review placed the heat-acclimation side: heat acclimation expands plasma volume, lowers resting core temperature, and protects severe-intensity performance in the heat, with the acclimation window typically 10-14 days ([28] Périard 2015, Level 1a). The [29] Ebert 2007 dehydration-performance study reached the same conclusion from the dehydration-performance side: 2% body-mass loss reduced time-to-exhaustion by 28% in trained cyclists, and indoor warm-up rooms with poor ventilation can shift the hydration balance before the start ([29] Ebert 2007, Level 2b). The operational rule: in cold environments, extend the warm-up by 3-5 minutes and include an extra layer for the first 500 m; in warm environments, hydrate aggressively in the 1-2 hours before the start and use a fan if available; in indoor environments, hold the room temperature at 18-22 degrees Celsius and monitor humidity.

Drag factor and warm-up

Drag factor is the rower's controllable lever on the perceived intensity of each stroke, and the literature has converged on holding the same drag factor across trials for valid rank submissions ([1] Concept2, Level 5; [3] Concept2, Level 5; [4] Concept2, Level 5; [5] Concept2, Level 5; [6] Concept2, Level 5). The [4] Concept2 damper-setting governance placed the drag-factor anchor: the rower-choice variable on the indoor rower is the damper setting (typically 100-130 on the Concept2 PM5), and the damper setting shifts the perceived intensity of the first 500 m and the back-half sustainability ([4] Concept2, Level 5). The [5] Concept2 Logbook governance reached the same conclusion from the monitor-calibration side: Concept2 recommends periodic monitor calibration and consistent drag factor settings across trials, with the same monitor and the same drag factor required for valid rank submissions ([5] Concept2, Level 5).

The [6] Concept2 PM5 Performance Monitor governance placed the monitor-side: the PM5 monitor reads drag factor directly, and the rower who uses a different monitor for the warm-up and the test introduces a calibration risk ([6] Concept2, Level 5). The operational rule: use the same monitor, the same drag factor (typically 100-130 on the Concept2 PM5 damper), and confirm the drag factor reading on the monitor before the warm-up. The honest read: the rower who treats drag factor as a rower-choice variable rather than a fixed constant absorbs the work better than the rower who changes drag factor between trials; the rower who warms up at a different drag factor than the test introduces a calibration risk that the monitor will catch.

Caffeine as warm-up aid

Caffeine is the rower's largest single-supplement lever on severe-intensity performance, and the literature has converged on 3-6 mg/kg of body weight taken 30-60 minutes before the start as the optimal dose for endurance and severe-intensity rowing ([53] Grgic 2019, Level 1a; [54] Grgic 2021, Level 1a; [88] EFSA 2015, Level 5; [90] Robertson 2004, Level 5). The [53] Grgic 2019 caffeine umbrella review placed the ergogenic side: caffeine produces small-to-moderate ergogenic effects on endurance and severe-intensity performance in most task-specific contexts ([53] Grgic 2019, Level 1a). The [54] Grgic 2021 caffeine meta-analysis update reached the same conclusion from the dose-response side: caffeine produces small ergogenic effects on endurance and severe-intensity performance, with the largest benefits at 3-6 mg/kg ([54] Grgic 2021, Level 1a).

The [88] EFSA 2015 caffeine-safety opinion placed the safety-governance side: no more than 200 mg per dose and 400 mg per day for healthy adults, with the safety profile well-characterised in the general population ([88] EFSA 2015, Level 5). The operational rule: 3-6 mg/kg of body weight taken 30-60 minutes before the start, with the rower who is caffeine-naive starting at the lower end of the range and the rower who is caffeine-habituated using the same dose as their training dose. The honest read: caffeine is a real lever on severe-intensity performance, but the dose-response curve is individual, and the rower who experiments with caffeine in training rather than on race day reads the test more honestly.

Carbohydrate pre-event

Carbohydrate pre-event is the rower's substrate lever on the back half of the test, and the literature has converged on 1-3 g/kg of body weight taken 1-3 hours before the start as the optimal pre-event carbohydrate dose ([55] Thomas 2016, Level 5; [56] Burke 2011, Level 1a; [63] Kerksick 2018, Level 1a; [64] Ivy 1988, Level 1b; [65] Burke 2017, Level 5; [89] Burke 2018, Level 1a). The [55] Thomas 2016 joint ACSM/AND/DC nutrition position stand placed the canonical-nutrition side: carbohydrate-plus-protein combinations are the standard pre-event meal pattern for moderate-to-hard training ([55] Thomas 2016, Level 5). The [56] Burke 2011 carbohydrate-intake framework reached the same conclusion from the carbohydrate-frame side: carbohydrate intake for training and competition is the canonical substrate anchor for the rower pre-event ([56] Burke 2011, Level 1a).

The [89] Burke 2018 pre-exercise-carbohydrate-fuelling review placed the pre-exercise-carbohydrate-fuelling side: carbohydrate intake in the 1-3 hours before exercise improves endurance performance, with the largest benefits in events longer than ~60 minutes or in events where the back half is the limiting factor ([89] Burke 2018, Level 1a). The [64] Ivy 1988 glycogen-synthesis study placed the early-timing side: muscle glycogen synthesis is significantly greater when carbohydrate is consumed within the first two hours after exercise, with implications for the race-week glycogen-loading pattern ([64] Ivy 1988, Level 1b). The [63] Kerksick 2018 ISSN review reached the same conclusion from the macronutrient-timing side: pre-event carbohydrate and protein timing anchors for the rower on race day ([63] Kerksick 2018, Level 1a). The operational rule: 1-3 g/kg of carbohydrate taken 1-3 hours before the start, with the rower who tolerates solid food eating a rice-based or pasta-based meal 3 hours before and the rower who prefers liquid eating a sports drink 30-60 minutes before.

Hydration pre-event

Hydration pre-event is the rower's thermoregulation lever on the back half of the test, and the literature has converged on 500-750 mL of fluid in the 2-3 hours before the start as the optimal pre-event hydration dose ([59] Sawka 2007, Level 5; [60] Shirreffs 2011, Level 5; [61] EFSA 2010, Level 5; [67] Halson 2014 sleep, Level 5). The [59] Sawka 2007 ACSM fluid-replacement position stand placed the canonical-hydration side: the rate of fluid replacement should match the rate of sweat loss as closely as practical, with sodium added when sessions exceed ~60 minutes ([59] Sawka 2007, Level 5). The [60] Shirreffs 2011 fluid-and-electrolyte-needs review reached the same conclusion from the per-rower-fluid-ladder side: per-rower sweat rate is the per-rower fluid replacement target ([60] Shirreffs 2011, Level 5).

The [61] EFSA 2010 water DRVs placed the daily-hydration-governance side: total daily water intake of 2.5-3.5 L for men and 2.0-2.7 L for women, with the pre-event window an extension of the daily plan ([61] EFSA 2010, Level 5). The [67] Halson 2014 sleep-and-nutrition review placed the recovery-sleep side: hydration interacts with sleep, and the night-before-test hydration state affects the morning-of-test hydration state ([67] Halson 2014 sleep, Level 5). The operational rule: 500-750 mL of fluid in the 2-3 hours before the start, with sodium added when the test exceeds ~60 minutes or when the room temperature exceeds 22 degrees Celsius.

Sodium pre-load

Sodium pre-load is the rower's plasma-volume lever on events longer than ~60 minutes, and the literature has converged on ~300-500 mg/h of sodium taken in the 1-2 hours before the start as the optimal pre-event sodium dose ([59] Sawka 2007, Level 5; [62] Sims 2015, Level 1a). The [62] Sims 2015 sodium-loading review placed the plasma-volume-expansion side: sodium pre-loading expands plasma volume and protects performance in events longer than ~60 minutes or in warm environments ([62] Sims 2015, Level 1a). The [59] Sawka 2007 ACSM fluid-replacement position stand reached the same conclusion from the sodium-and-fluid side: sodium replacement should scale to sweat sodium and to session length, with the pre-event window a sub-component of the total sodium plan ([59] Sawka 2007, Level 5). The operational rule: ~300-500 mg/h of sodium in the 1-2 hours before the start, with the rower who is sodium-sensitive starting at the lower end of the range.

Mental prep: arousal regulation, breathing, visualisation

Mental prep is the rower's arousal-regulation lever on the first 500 m, and the literature has converged on a four-component framework: imagery, self-talk, arousal regulation, and pre-performance routine ([37] Sheikh 1996, Level 5; [39] Birrer 2012, Level 5; [40] Gould 2002, Level 5; [90] Robertson 2004, Level 5; [91] Eston 2012, Level 5; [92] Smirmaul 2012, Level 5; [93] Tucker 2006, Level 5; [94] Marcora 2009, Level 2b; [95] Pageaux 2014, Level 5). The [90] Robertson 2004 perceived-exertion review placed the RPE-monitoring side: RPE is a real-time monitoring lever on exercise intensity, with the Borg 6-20 and CR-10 scales the principal instruments ([90] Robertson 2004, Level 5). The [91] Eston 2012 RPE-validation review reached the same conclusion from the validation side: RPE is a valid real-time monitoring lever on exercise intensity across many task-specific contexts ([91] Eston 2012, Level 5).

The [92] Smirmaul 2012 sense-of-effort review placed the central-governor side: perceived effort is a real-time modulator of pacing, with the central governor model the principal framework ([92] Smirmaul 2012, Level 5). The [93] Tucker 2006 pacing-regulation review reached the same conclusion from the teleoanticipation side: pacing is regulated by perception of effort and prior experience, with the teleoanticipation model the principal framework ([93] Tucker 2006, Level 5). The [94] Marcora 2009 mental-fatigue study placed the mental-fatigue side: mental fatigue reduces time to exhaustion in endurance exercise, with implications for the rower on race day ([94] Marcora 2009, Level 2b). The [95] Pageaux 2014 psychobiological-endurance-performance model placed the psychobiological side: endurance performance is regulated by perception of effort, motivation, and prior experience, with implications for race-day mental warm-up ([95] Pageaux 2014, Level 5).

The operational rule: 2-3 minutes of mental rehearsal of the race plan, a brief arousal-regulation breath (4-7-8 or box breath), and the pre-performance routine written down on the monitor or on a card. The honest read: the rower who treats the mental warm-up as part of the result rather than as an afterthought absorbs the first 500 m more efficiently than the rower who treats it as a delay to the test.

Pre-race routine: the hour before

The pre-race routine is the rower's hour-before framework for sleep, hydration, warm-up, nutrition, and the pre-performance routine, and the literature has converged on a multi-component framework that holds across the night-before, the morning-of, and the hour-before windows ([1] Concept2, Level 5; [15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [47] Ingham 2002, Level 2b; [48] Hagerman 1984, Level 5; [53] Grgic 2019, Level 1a; [55] Thomas 2016, Level 5; [59] Sawka 2007, Level 5; [60] Shirreffs 2011, Level 5). The [1] Concept2 Warm-up governance placed the manufacturer anchor: the pre-race routine is a real lever on the first 500 m of severe-intensity rowing, and Concept2 recommends a 10-15 minute warm-up for a 2K and a longer warm-up for a 5K or longer ([1] Concept2, Level 5). The [25] Murtagh 2018 rowing-specific load-management review reached the same conclusion from the rowing-context side: indoor rowers benefit from a sport-specific warm-up that primes the legs, the trunk, and the rate caps before a hard piece ([25] Murtagh 2018, Level 1a).

The operational pre-race routine: (1) the night before, hold 7-9 hours of sleep with consistent timing; (2) the morning of, hold a normal breakfast with 1-3 g/kg of carbohydrate and ~0.4 g/kg of protein, and hydrate to 500-750 mL; (3) 2-3 hours before the start, complete the pre-event meal with carbohydrate-plus-protein; (4) 60 minutes before the start, complete the warm-up; (5) 5-10 minutes before the start, complete the pre-performance routine and the mental rehearsal. The honest read: the rower who holds the pre-race routine across trials gets the more repeatable signal; the rower who wings it absorbs the work less well.

Eating-disorder red line: warm-up fasting

The eating-disorder red line is the rower's safety anchor for the pre-event window, and the literature has converged on a clear set of warning signs that warrant stopping the warm-up and seeking clinical advice ([79] Mountjoy 2018, Level 5; [80] Mountjoy 2014, Level 5; [81] Sundgot-Borgen 2004, Level 4; [82] Wasserfurth 2020, Level 5; [83] NIH ODS, Level 5). The [79] Mountjoy 2018 IOC RED-S consensus placed the eating-disorder-and-low-energy-availability anchor: relative energy deficiency in sport (RED-S) is a clinical syndrome that includes eating-disorder patterns, menstrual dysfunction, and impaired bone health, and the pre-event window is a sensitive time for energy-availability decisions ([79] Mountjoy 2018, Level 5). The [80] Mountjoy 2014 IOC consensus update reached the same conclusion from the broader-RED-S-framework side: the IOC framework extends the Female Athlete Triad into the broader RED-S framework, with implications for masters rowers, male rowers, and adaptive rowers ([80] Mountjoy 2014, Level 5).

The [81] Sundgot-Borgen 2004 eating-disorders-in-elite-athletes study placed the elite-athlete-prevalence side: elite athletes show higher rates of disordered eating than the general population across sports ([81] Sundgot-Borgen 2004, Level 4). The [82] Wasserfurth 2020 RED-S clinical review placed the clinical-anchor side: impaired metabolic health in athletes associated with relative energy deficiency in sport; the clinical anchor for the rower on race day ([82] Wasserfurth 2020, Level 5). The [83] NIH ODS Dietary Supplements for Exercise and Athletic Performance resource placed the supplement-governance side: ergogenic aids in the pre-event window should be evidence-based and clinician-cleared ([83] NIH ODS, Level 5).

The operational rule: the rower who is fasting in the pre-event window to "save weight" or to "sharpen the race" is on the RED-S spectrum, and the medical-stop discipline is the rower's safety anchor. The honest read: the rower who treats the pre-event meal as a per-bolus substrate opportunity absorbs the work better than the rower who treats it as a discipline move; the rower who experiences eating-disorder patterns, GI distress that does not resolve, or cardiac symptoms during warm-up should stop and seek clinical advice.

Recovery between warm-up and event (5-10 min settle)

Recovery between warm-up and event is the rower's settling window, and the literature has converged on 3-5 minutes for short pieces (500 m, 2K) and 4-5 minutes for longer pieces (5K, 6K, 30 min) ([15] Bishop 2008, Level 1a; [16] Faulkner 2007, Level 2b; [17] Tomaras 2019, Level 2b). The [15] Bishop 2008 warm-up II review placed the settling-window side: the duration between the final high-intensity component and the start of the test should be 3-5 minutes, with the rower returning to conversational pace during the settling window ([15] Bishop 2008, Level 1a). The [16] Faulkner 2007 warm-up behaviour study reached the same conclusion from the physiological side: heart rate, ventilation, and oxygen uptake all return toward baseline during the settling window, with the rower who rests at conversational pace allowing the physiological state to stabilise ([16] Faulkner 2007, Level 2b).

The [17] Tomaras 2019 warm-up-intensity study placed the settling-time-interaction side: settling times longer than 5 minutes did not produce larger performance gains, and settling times shorter than 2 minutes did not allow adequate physiological recovery from the warm-up ([17] Tomaras 2019, Level 2b). The operational rule: finish the final high-intensity rep 3-5 minutes before the start, drop to conversational pace (zone 1-2) during the settling window, and use the final 60 seconds for the pre-performance routine (mental rehearsal, breath, rate-cap confirmation).

Distance-specific warmup, pacing, and cooldown templates

The distance-specific templates below are the rower's pre-test framework for the five standard Concept2 indoor rowing test distances: 500 m, 2K, 5K, 6K, and 30 min. The [15] Bishop 2008 warm-up II review placed the warm-up-structure anchor: warm-up should comprise a general aerobic component, a sport-specific component, and a final high-intensity component, scaled to the test distance ([15] Bishop 2008, Level 1a). The [25] Murtagh 2018 rowing-specific load-management review reached the same conclusion from the rowing-context side: indoor rowers benefit from a sport-specific warm-up that primes the legs, the trunk, and the rate caps before a hard piece ([25] Murtagh 2018, Level 1a).

| Phase | 500 m | 2K | 5K | 6K | 30 min | |---|---|---|---|---|---| | Warmup length | 5-8 min easy + 3 × 30 s rate-cap build ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [1] Concept2, Level 5) | 10 min easy + 3 × 500 m build + 4 × 30 s rate-cap build ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [1] Concept2, Level 5) | 10-12 min easy + 2 × 1000 m build + 4 × 30 s rate-cap build ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [1] Concept2, Level 5) | 12-15 min easy + 2 × 1500 m build + 4 × 30 s rate-cap build ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [1] Concept2, Level 5) | 12-15 min easy + 2 × 1000 m build + 4 × 30 s rate-cap build ([15] Bishop 2008, Level 1a; [25] Murtagh 2018, Level 1a; [1] Concept2, Level 5) | | Settle time | 3 min before start ([15] Bishop 2008, Level 1a) | 5 min before start ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b) | 4 min before start ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b) | 4 min before start ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b) | 4 min before start ([15] Bishop 2008, Level 1a; [17] Tomaras 2019, Level 2b) | | Race start | Rate 36-40, anaerobic surge ([48] Hagerman 1984, Level 5; [47] Ingham 2002, Level 2b) | Rate 30-34, controlled-positive ([45] Garland 2005, Level 4; [46] Astridge 2024, Level 2b) | Rate 24-28, even-split ([46] Astridge 2024, Level 2b; [47] Ingham 2002, Level 2b) | Rate 24-28, even-split ([46] Astridge 2024, Level 2b; [47] Ingham 2002, Level 2b) | Rate 22-26, even-split ([46] Astridge 2024, Level 2b; [47] Ingham 2002, Level 2b) | | Cooldown | 8-10 min easy (zone 1-2) at rate 18-22 ([25] Murtagh 2018, Level 1a; [48] Hagerman 1984, Level 5) | 10-15 min easy (zone 1-2) at rate 18-22 ([25] Murtagh 2018, Level 1a; [48] Hagerman 1984, Level 5) | 10-15 min easy (zone 1-2) at rate 18-22 ([25] Murtagh 2018, Level 1a; [48] Hagerman 1984, Level 5) | 10-15 min easy (zone 1-2) at rate 18-22 ([25] Murtagh 2018, Level 1a; [48] Hagerman 1984, Level 5) | 10-15 min easy (zone 1-2) at rate 18-22 ([25] Murtagh 2018, Level 1a; [48] Hagerman 1984, Level 5) |

Conditions for test comparability: monitor, rower, sleep, recent training

Test-result comparability requires the same conditions across trials, and the literature has converged on four anchors: monitor, rower state, sleep, and recent training ([5] Concept2, Level 5; [8] Concept2, Level 5; [9] Concept2, Level 5; [10] World Rowing, Level 5; [13] British Rowing, Level 5; [49] Schabort 1999, Level 2b; [50] Currell 2007, Level 2b; [51] Jeukendrup 1996, Level 2b). The [50] Currell 2007 time-trial reliability study placed the validity-and-reliability side: a validated time-trial protocol produces low within-subject variability when conditions, monitor, and warm-up are held constant ([50] Currell 2007, Level 2b). The [51] Jeukendrup 1996 validated endurance performance test reached the same conclusion from the validation-protocol side: a structured endurance performance test produces consistent results when the warm-up, equipment, and pacing plan are held constant across trials ([51] Jeukendrup 1996, Level 2b).

The [49] Schabort 1999 2K-reliability study placed the rowing-specific side: three 2K trials in trained rowers gave coefficient of variation 2.0% for mean power and retest correlation 0.96, establishing the noise band a warm-up plan must beat to be detectable ([49] Schabort 1999, Level 2b). The [5] Concept2 Logbook governance reached the same conclusion from the monitor-calibration side: Concept2 recommends periodic monitor calibration and consistent drag factor settings across trials, with the same monitor and the same drag factor required for valid rank submissions ([5] Concept2, Level 5). The [10] World Rowing indoor rowing discipline governance reached the same conclusion from the international-governance side: World Rowing standardises indoor rowing race categories, monitor specifications, and result-validation rules for sanctioned competitions ([10] World Rowing, Level 5). The [13] British Rowing Go Row Indoor tests governance reached the same conclusion from the federation-coaching side: UK federation plain-language interpretation guide for indoor rowing tests describes how to read 2K, 5K, and other test scores in the context of personal fitness ([13] British Rowing, Level 5). The operational rule: use the same monitor, the same drag factor (typically 100-130 on the Concept2 PM5 damper), the same room temperature, the same sleep the night before, and the same recent training load; for an in-depth comparability framework, see our what-makes-a-test-repeatable guide and our ranking-scores-and-percentiles-a-calm-interpretation guide.

Repeatability and the "good day" trap

The "good day" trap is the rower's recurring temptation to over-interpret a single favourable result, and the literature has converged on within-subject variability as the rower's caution sign ([45] Garland 2005, Level 4; [49] Schabort 1999, Level 2b; [50] Currell 2007, Level 2b; [51] Jeukendrup 1996, Level 2b). The [50] Currell 2007 time-trial reliability study placed the sensitivity side: even with carefully controlled conditions, within-subject variation in time-trial performance falls in the range of ~1-3 percent, and a single favourable result must clear the within-subject corridor before being treated as a real improvement ([50] Currell 2007, Level 2b). The [51] Jeukendrup 1996 validated endurance performance test reached the same conclusion from the validation-protocol side: a single result on a validated endurance test is a noisy estimate of true endurance capacity, and multiple trials are required to confirm a change ([51] Jeukendrup 1996, Level 2b).

The [49] Schabort 1999 2K-reliability study placed the rowing-specific side: three 2K trials in trained rowers gave coefficient of variation 2.0% for mean power and retest correlation 0.96, establishing the noise band a warm-up plan must beat to be detectable ([49] Schabort 1999, Level 2b). The [45] Garland 2005 elite-2K pacing-profile study placed the elite-shape side: the empirical 2K profile is reverse-J, with a fast first 500 m, a slowest third 500 m, and a small finishing lift, and the warm-up must rehearse the first 500 m ([45] Garland 2005, Level 4). The operational rule: a single result that is a clear improvement over the previous result is a hypothesis, not a conclusion; the rower who treats it as a hypothesis plans the next session to confirm or refute it, and the rower who treats it as a conclusion has fallen into the "good day" trap.

HRV-guided race-week preparation

HRV is the rower's autonomic-recalibration signal in the race-week window, and the literature has converged on rolling-baseline averages rather than day-to-day spikes ([71] Halson 2014 monitoring, Level 5; [72] Buchheit 2014, Level 1a; [73] Plews 2018, Level 1b; [74] Fullagar 2015, Level 1a). The [73] Plews 2018 rowing-specific HRV comparison placed the rowing-specific HRV side: rowers benefit from a sport-specific multi-modal monitoring approach that pairs HRV with subjective wellness and training-load tracking, with rolling-baseline averages outperforming day-to-day spike detection ([73] Plews 2018, Level 1b). The [72] Buchheit 2014 monitoring-training-status-with-HR-measures review reached the same conclusion from the HRV-monitoring side: HRV-guided training uses rolling-baseline averages (typically 7-day) and individual variability, with day-to-day spikes too noisy to drive training decisions ([72] Buchheit 2014, Level 1a).

The [71] Halson 2014 training-load monitoring review placed the multi-modal-signal side: heart rate variability, sleep duration, sleep quality, and subjective wellness together catch the early fatigue signal before it becomes the late recovery signal, and the race-week window is particularly sensitive to multi-modal shifts ([71] Halson 2014 monitoring, Level 5). The [74] Fullagar 2015 sleep-and-athletic-performance review placed the post-test sleep-and-reaction-time side: poor sleep impairs reaction time, decision-making, and motor performance the following day, with the race-week window particularly sensitive to sleep loss ([74] Fullagar 2015, Level 1a). The operational rule: measure HRV first thing in the morning for 1-3 minutes; compare to a 7-day rolling baseline; treat a 7-day average that is more than one standard deviation below the rower's typical baseline as a "hold race-week intensity" signal; hold race-week intensity when the 7-day average returns to baseline.

Limitations

Race-day warm-up research in indoor rowers has limits. The [25] Murtagh 2018 rowing-specific load-management review placed the rowing-context caveat: rowing-specific warm-up evidence is thinner than running or cycling evidence, and the rower's per-rower implementation is the work ([25] Murtagh 2018, Level 1a). The [30] Jones 2006 VO2-kinetics review placed the VO2-kinetics caveat: most VO2-kinetics evidence is from cycling and running rather than rowing, and the rowing-specific transfer is a conceptual rather than empirical anchor ([30] Jones 2006, Level 1a). The [79] Mountjoy 2018 IOC RED-S consensus reached the same conclusion from the eating-disorder side: the long-term effects of pre-event warm-up routines on eating-disorder risk are still being characterised, especially in masters and adaptive rowers ([79] Mountjoy 2018, Level 5).

The [53] Grgic 2019 caffeine umbrella review placed the caffeine-dosing caveat: the dose-response curve for caffeine is individual, and the rower who experiments with caffeine in training rather than on race day reads the test more honestly ([53] Grgic 2019, Level 1a). The [54] Grgic 2021 caffeine meta-analysis update placed the population-side caveat: most caffeine evidence is from male endurance athletes rather than indoor rowers specifically, and the per-rower scaling is the work ([54] Grgic 2021, Level 1a). The [60] Shirreffs 2011 fluid-and-electrolyte-needs review reached the same conclusion from the per-rower-fluid-ladder side: per-rower sweat rate is the per-rower fluid replacement target, and the population-level average is a starting point rather than a destination ([60] Shirreffs 2011, Level 5).

The honest read for the rower: race-day warm-up is a per-rower implementation, and the rower's per-rower scaling is the work. The peer-reviewed literature on warm-up physiology, intensity and duration, specific versus general warm-up, dynamic versus static stretching, race-rhythm rehearsal, mental warm-up, post-activation potentiation, settling time, distance-specific templates, conditions, drag factor, caffeine, hydration, sodium pre-load, pre-race routine, comparability, HRV-guided race-week preparation, and the eating-disorder red line is converging but still young for the long tail — dose-response in female rowers, masters rowers, and adaptive rowers; the long-term effects of pre-event warm-up routines on rowing-specific adaptation; the optimal distance-specific warmup and pacing protocols for indoor rowers; and the cost-effectiveness of structured pre-race routines across a season. The honest coach names the boundary. The honest rower asks about it.

Summary in one paragraph

Race-day warm-up is the rower's pre-test system for turning the body's stored physiology into the result on the ergometer, and the peer-reviewed literature has converged on a small set of levers that move the first 500 m of severe-intensity rowing and the back half of threshold pieces. The [1] Concept2 Warm-up governance placed the manufacturer anchor ([1] Concept2, Level 5). The [2] Concept2 Pacing governance placed the manufacturer-pacing anchor ([2] Concept2, Level 5). The [3] Concept2 2K governance placed the manufacturer-2K anchor ([3] Concept2, Level 5). The [4] Concept2 Damper governance placed the drag-factor anchor ([4] Concept2, Level 5). The [5] Concept2 Logbook governance placed the monitor-calibration anchor ([5] Concept2, Level 5). The [6] Concept2 PM5 governance placed the monitor-side anchor ([6] Concept2, Level 5).

The right posture is to treat race-day warm-up as a multi-component pre-test system built on warm-up physiology, intensity and duration, specific versus general warm-up, dynamic versus static stretching, race-rhythm rehearsal, mental warm-up, post-activation potentiation, settling time, distance-specific templates, conditions, drag factor, caffeine, hydration, sodium pre-load, the pre-race routine, comparability, HRV-guided race-week preparation, and the eating-disorder red line. The rower who plans the warm-up to scale with the test distance — short for a 500 m sprint, longer and more structured for a 2K, 5K, 6K, or 30-minute piece — and who rehearses the rate caps and stroke rhythm rehearses the test rather than hoping for it. Race-day warm-up is the cheapest split-second gain on the ergometer, and the rower who treats the warm-up as part of the result rather than as a five-minute ritual absorbs the work faster than the rower who treats it as a delay to the test.

What to do with this article

Read the premise: warm-up is the cheapest split-second gain on the ergometer, and the structured general aerobic plus sport-specific plus high-intensity warm-up outperforms general warm-up alone for severe-intensity rowing. The [15] Bishop 2008 review places this on the warm-up-structure side; the [25] Murtagh 2018 review places it on the rowing-context side; the [41] Cumming 2008 meta-analysis places it on the mental-rehearsal side.

Read the warm-up physiology section: warm-up raises muscle temperature, accelerates pulmonary VO2 kinetics, and primes the motor units; the magnitude scales to warm-up intensity and to the cold-side baseline. The [16] Faulkner 2007 study places this on the physiological-response side; the [30] Jones 2006 review places it on the VO2-kinetics side; the [31] Burnley 2010 review places it on the prior-exercise-priming side.

Read the intensity and duration section: warm-up comprises 5-15 minutes of moderate-intensity work followed by 1-3 minutes of high-intensity work, with the duration scaled to the test distance; higher-intensity and longer-duration warm-ups produce larger performance gains. The [15] Bishop 2008 review places this on the warm-up-structure side; the [17] Tomaras 2019 study places it on the higher-intensity side; the [18] Andzelm 2014 study places it on the duration side.

Read the specific versus general section: sport-specific warm-up outperforms general warm-up for severe-intensity rowing; warm up on the rower rather than on a separate machine. The [15] Bishop 2008 review places this on the warm-up-structure side; the [23] Young 2002 study places it on the specific-priming side; the [25] Murtagh 2018 review places it on the rowing-context side.

Read the stretching section: dynamic mobility work is the preferred pre-event warm-up component; static stretching in the pre-event window costs measurable power and should be reserved for the post-event cooldown. The [22] Simic 2013 meta-analysis places this on the pre-event-static-stretching side; the [19] Behm 2016 meta-analysis places it on the broader-acute-stretching side; the [21] Page 2012 review places it on the stretching-taxonomy side.

Read the race-rhythm rehearsal section: 3-4 short strokes at increasing rate caps at the end of the warm-up prime the nervous system and the VO2 kinetics, finishing 3-5 minutes before the start. The [25] Murtagh 2018 review places this on the rowing-context side; the [1] Concept2 governance places it on the manufacturer-side; the [31] Burnley 2010 review places it on the priming-mechanism side.

Read the mental warm-up section: mental warm-up combines imagery, self-talk, arousal regulation, and the pre-performance routine; 2-3 minutes of mental rehearsal of the race plan primes the nervous system for the first stroke. The [38] Feltz 2013 meta-analysis places this on the imagery side; the [40] Gould 2002 survey places it on the coach-discipline side; the [39] Birrer 2012 review places it on the psychological-skills side.

Read the settling-time section: finish the final high-intensity rep 3-5 minutes before the start, drop to conversational pace during the settling window, and use the final 60 seconds for the pre-performance routine. The [15] Bishop 2008 review places this on the settling-time side; the [17] Tomaras 2019 study places it on the cycling-time-trial side; the [18] Andzelm 2014 study places it on the duration-interaction side.

Read the PAPE section: 1-3 near-maximal strokes at the end of the warm-up with 5-10 minutes of settling produce a small but real PAPE effect on severe-intensity rowing, with the largest benefit in stronger and well-trained rowers. The [32] Seitz 2016 meta-analysis places this on the PAPE-ergogenic side; the [33] Blazevich 2016 review places it on the PAP-versus-PAPE side; the [34] Behm 2017 review places it on the rowing-applicability side.

Read the warm-up degradation section: the warm-up effect degrades over 30-45 minutes; if the settling window is longer than 10 minutes, include a 30-60 second near-race-pace rep 3-5 minutes before the start to restore the priming effect. The [15] Bishop 2008 review places this on the warm-up-degradation side; the [16] Faulkner 2007 study places it on the physiological-degradation side; the [17] Tomaras 2019 study places it on the intensity-interaction side.

Read the distance-specific warm-up section: short pieces (500 m, 2K) require shorter warm-ups with a larger anaerobic component; longer pieces (5K, 6K, 30 min) require longer warm-ups with a larger aerobic component and a longer settling window. The [15] Bishop 2008 review places this on the warm-up-structure side; the [45] Garland 2005 study places it on the empirical-shape side; the [46] Astridge 2024 study places it on the cross-distance side.

Read the conditions section: cold environments require longer warm-ups; warm environments require aggressive pre-event hydration and heat acclimation; indoor environments require controlled room temperature and humidity. The [26] Castle 2006 study places this on the cold-environment side; the [27] Racinais 2015 consensus places it on the heat-acclimatisation side; the [28] Périard 2015 review places it on the heat-acclimation side.

Read the drag-factor section: use the same monitor and the same drag factor (typically 100-130 on the Concept2 PM5) for the warm-up and the test; confirm the drag factor reading on the monitor before the warm-up. The [4] Concept2 damper governance places this on the drag-factor anchor side; the [5] Concept2 logbook governance places it on the monitor-calibration side; the [6] Concept2 PM5 governance places it on the monitor-side.

Read the caffeine section: 3-6 mg/kg of body weight taken 30-60 minutes before the start is the optimal caffeine dose for endurance and severe-intensity rowing, with the safety profile well-characterised in the general population. The [53] Grgic 2019 umbrella review places this on the ergogenic side; the [54] Grgic 2021 meta-analysis update places it on the dose-response side; the [88] EFSA 2015 opinion places it on the safety-governance side.

Read the carbohydrate section: 1-3 g/kg of carbohydrate taken 1-3 hours before the start is the optimal pre-event carbohydrate dose, with the largest benefits in events longer than ~60 minutes. The [55] Thomas 2016 position stand places this on the canonical-nutrition side; the [56] Burke 2011 framework places it on the carbohydrate-frame side; the [89] Burke 2018 review places it on the pre-exercise-fuelling side.

Read the hydration section: 500-750 mL of fluid in the 2-3 hours before the start is the optimal pre-event hydration dose, with sodium added when the test exceeds ~60 minutes or when the room is warm. The [59] Sawka 2007 position stand places this on the canonical-hydration side; the [60] Shirreffs 2011 review places it on the per-rower-fluid-ladder side; the [61] EFSA 2010 opinion places it on the daily-hydration-governance side.

Read the sodium-pre-load section: ~300-500 mg/h of sodium in the 1-2 hours before the start is the optimal pre-event sodium dose, with the largest benefits in events longer than ~60 minutes or in warm environments. The [62] Sims 2015 review places this on the plasma-volume-expansion side; the [59] Sawka 2007 position stand places it on the sodium-and-fluid side.

Read the mental-prep section: mental prep combines imagery, self-talk, arousal regulation, and the pre-performance routine; 2-3 minutes of mental rehearsal of the race plan primes the nervous system for the first stroke. The [90] Robertson 2004 review places this on the RPE-monitoring side; the [93] Tucker 2006 review places it on the teleoanticipation side; the [94] Marcora 2009 study places it on the mental-fatigue side.

Read the pre-race routine section: the pre-race routine holds across the night-before, the morning-of, and the hour-before windows: sleep, breakfast, pre-event meal, warm-up, pre-performance routine, mental rehearsal. The [1] Concept2 governance places this on the manufacturer-side; the [25] Murtagh 2018 review places it on the rowing-context side; the [55] Thomas 2016 position stand places it on the nutrition-side.

Read the eating-disorder red line section: warm-up fasting is on the RED-S spectrum; the rower who treats the pre-event meal as a per-bolus substrate opportunity absorbs the work better than the rower who treats it as a discipline move. The [79] Mountjoy 2018 consensus places this on the eating-disorder-and-RED-S side; the [80] Mountjoy 2014 update places it on the broader-RED-S-framework side; the [81] Sundgot-Borgen 2004 study places it on the elite-athlete-prevalence side.

Read the distance-specific templates section: the 500 m, 2K, 5K, 6K, and 30 min templates scale the warmup, settle time, race start, and cooldown to the test distance; the rower who follows the template absorbs the work. The [15] Bishop 2008 review places this on the warm-up-structure side; the [25] Murtagh 2018 review places it on the rowing-context side; the [45] Garland 2005 study places it on the empirical-shape side.

Read the conditions-for-comparability section: use the same monitor, drag factor, room temperature, sleep, and recent training load across trials; within-subject variation is low when conditions hold. The [50] Currell 2007 study places this on the validity-and-reliability side; the [51] Jeukendrup 1996 study places it on the validation-protocol side; the [49] Schabort 1999 study places it on the rowing-specific side.

Read the HRV-guided race-week preparation section: HRV-guided race-week preparation uses 7-day rolling-baseline averages rather than day-to-day spikes; treat a 7-day average more than one standard deviation below baseline as a "hold race-week intensity" signal. The [73] Plews 2018 study places this on the rowing-specific side; the [72] Buchheit 2014 review places it on the HRV-monitoring side; the [71] Halson 2014 monitoring review places it on the multi-modal-signal side.

When the warm-up plan is working, the rower is treating the warm-up as part of the result rather than as a five-minute ritual; scaling the warm-up to the test distance — short for a 500 m sprint, longer and more structured for a 2K, 5K, 6K, or 30-minute piece; rehearsing the rate caps and stroke rhythm; finishing the final high-intensity rep 3-5 minutes before the start; including 1-3 near-maximal strokes at the end of the warm-up to capture the PAPE effect; holding the same monitor, drag factor, room temperature, sleep, and recent training load across trials; using the same warm-up template across trials; using the same pre-race routine across trials; using 3-6 mg/kg of caffeine taken 30-60 minutes before the start; using 1-3 g/kg of carbohydrate taken 1-3 hours before the start; using 500-750 mL of fluid in the 2-3 hours before the start; using ~300-500 mg/h of sodium in the 1-2 hours before the start; using 2-3 minutes of mental rehearsal of the race plan; using HRV-guided race-week preparation with 7-day rolling-baseline averages; and stopping and seeking clinical advice for eating-disorder red flags. When the plan is not working, the rower audits the daily sleep, checks for DOMS disproportionate to effort, audits the warm-up template, and asks a clinician or registered dietitian if the warm-up signal is not matching the work. Race-day warm-up is the cheapest split-second gain on the ergometer, and the rower who treats it as part of the result rather than as a five-minute ritual absorbs the work faster than the rower who treats it as a delay to the test.
