Description

Competitive swimmers are faced with a range of post-warm-up recovery times (PWRTs) during competitions. Previous exercise science literature suggests that the optimal PWRT is between 8-20 minutes. However, research specific to competitive swimmers has focused on comparisons to longer PWRTs. Further, there is limited research comparing multiple PWRTs, especially PWRTs less than 20 minutes. PURPOSE To investigate the impact of PWRTs ranging from 5-20 minutes prior to swim performance. METHODS Baseline heart rate and core temperature were estimated at the start of each session. Swimmers then completed a standardized swim warm-up. Measures of heart rate (HR), skin temperature (ST), and RPE were estimated upon completion. Participants were then randomly assigned one of four groups to rest for either 5 minutes (5PWRT), 10 minutes (10PWRT), 15 minutes (15PWRT), or 20 minutes (20PWRT). Each participant completed all conditions on different days. Heart rate, temperature, and RPE were recorded at the end of the PWRT. Lastly, participants completed a maximal swim of 100 yards. Total time and splits at each 50 yards were recorded, in addition to HR, ST, and RPE immediately after the completion of the swim. RESULTS Pairwise comparisons displayed a significant difference (p < 0.05) between baseline HR and PWRT HR in all conditions (5PWRT; 85 ± 10.1 vs 104 ± 15.5 bpm, 10PWRT; 79 ± 8.8 vs 103 ± 17.9 bpm, 15PWRT; 84 ± 10.6 vs 99 ± 14.4 bpm, 20PWRT; 82 ± 8.7 vs 98 ± 13.5 bpm). ST was significantly lower when compared to 15PWRT and 20PWRT (95.5 ± 1.8° vs 97.5 ± 0.8° and 97.6 ± 0.7° respectively; p < 0.05). Pairwise comparisons for heart and swim performance displayed no difference between PWRTs.

CONCLUSION While there were no differences between performance and physiological variables across the PWRT conditions, heart rate remained significantly elevated in all PWRT conditions compared to baseline.
