This study investigated whether contrast water therapy (CWT) has a dose-response effect on recovery from high-intensity cycling. Eleven trained male cyclists completed four trials, each commencing with a 75-min cycling protocol containing six sets of five 15-s sprints and three 5-min time-trials in thermoneutral conditions. Ten minutes post-exercise, participants performed one of four recovery protocols: CWT for 6 min (CWT6), 12 min (CWT12), or 18 min (CWT18) duration, or a seated rest control trial. The CWT commenced in hot water (38.4 ± 0.6°C) and alternated between hot and cold water (14.6 ± 0.3°C) every minute with a 5-s changeover. The cycling protocol was repeated 2 h after completion of exercise bout one. Prior to exercise bout two, core temperature was lower in CWT12 (-0.19 ± 0.14°C, mean ± 90% CL) and CWT18 (-0.21 ± 0.10°C) than control. Compared with control, CWT6 substantially improved time-trial (1.5 ± 2.1%) and sprint performance (3.0 ± 3.1%), and CWT12 substantially improved sprint total work (4.3 ± 3.4%) and peak power (2.7 ± 3.8%) in exercise bout two. All CWT conditions generally improved thermal sensation, whole body fatigue and muscle soreness compared with control, but no differences existed between conditions in heart rate or rating of perceived exertion. In conclusion, CWT duration did not have a dose-response effect on recovery from high-intensity cycling; however, CWT for up to 12 min assisted recovery of cycling performance.
本研究旨在探讨对比水疗（CWT）对高强度骑行恢复是否具有剂量反应效应。11 名训练有素的男性自行车运动员完成了四项试验，每项试验均从 75 分钟的骑行方案开始，该方案包括在热中性条件下进行六组五次 15 秒冲刺和三次 5 分钟计时赛。运动后 10 分钟，参与者进行了以下四项恢复方案之一：CWT 6 分钟（CWT6）、12 分钟（CWT12）或 18 分钟（CWT18），或坐姿休息对照试验。CWT 从 38.4 ± 0.6°C 的热水开始，每 1 分钟交替使用热水和冷水（14.6 ± 0.3°C），转换时间为 5 秒。运动方案在运动结束后 2 小时再次重复。在第二次运动前，CWT12（-0.19 ± 0.14°C，平均值±90%置信区间）和 CWT18（-0.21 ± 0.10°C）的核心温度低于对照。与对照相比，CWT6 显著提高了计时赛（1.5 ± 2.1%）和冲刺表现（3.0 ± 3.1%），CWT12 显著提高了冲刺总工作量（4.3 ± 3.4%）和冲刺峰值功率（2.7 ± 3.8%）。与对照相比，所有 CWT 条件均显著改善了热感觉、全身疲劳和肌肉酸痛，但各条件之间的心率或感知努力评分没有差异。总之，CWT 持续时间对高强度骑行后的恢复没有剂量反应效应；然而，CWT 持续 12 分钟有助于恢复骑行表现。
