Influence of post-warm-up recovery time on swim performance in international swimmers

Does post-warm-up rest interval affect the diurnal variation of 30-s Wingate cycle ergometry?

“…Likewise, in competition, this interval can vary, in terms of sports rules, from a few minutes in athletics, up to 45 min in swimming. To our best knowledge, relatively few studies have investigated the effect of rest interval separating WU from exercise performance (Poprzęcki et al 2007;Zochowski et al 2007;West et al 2013). Furthermore, we did not find data examining the effect of time-of-day and rest interval on the high-intensity cycling performance.…”

“…The effectiveness of the warm-up on high-intensity effort performance is influenced by its intensity, duration, and the rest interval separating the warm-up and the exercise performance (Bishop 2003;West et al 2013). The rest interval, often introduced between the WU and the onset of exercise, must be long enough to allow for the replenishment of phosphocreatine stores and not so long that muscle temperature and _ V O 2 return to baseline (Zochowski et al 2007).…”

Heated jackets and dryland-based activation exercises used as additional warm-ups during transition enhance sprint swimming performance

“…23 In the present study, T core increased during the pool warm-up by a similar magnitude (∼0.7 ± 0.1 • C) to previous reports. 3 However during transition, T core declined within all conditions, with a significant ∼0.6 • C reduction recorded under the Control condition. This magnitude of reduction in T core is greater than previously reported, 3,5,24 though a longer transition phase (more common in swimming competitions) was investigated in this study (30 versus 10-20 min).…”

“…Importantly, core temperature (T core ) remained elevated during the shorter transition. 3 It seems there is a greater risk of a significant decline in T core with longer transitions. Indeed muscle temperature (T muscle ) declines immediately following exercise, with a significant reduction evident after ∼15-20 min of recovery.…”

“…[1][2][3] After the pool warm-up, swimmers must change into their racing swimsuit, confer with their coach and report to marshalling ∼15-20 min prior to race start, 3 thus transition phases of 30-45 min are not uncommon. 3 Several studies have demonstrated that reducing the transition from 45 to 20 min, 3 or to 10 min, 4 yields faster 200 m swimming performance (∼1.5% and ∼1.4%, respectively). Importantly, core temperature (T core ) remained elevated during the shorter transition.…”
