This study aimed to investigate the effect of cold and thermoneutral water immersion on post-exercise parasympathetic reactivation, inferred from heart rate (HR) recovery (HRR) and HR variability (HRV) indices. Twelve men performed, on three separate occasions, an intermittent exercise bout (all-out 30-s Wingate test, 5 min seated recovery, followed by 5 min of submaximal running exercise), randomly followed by 5 min of passive (seated) recovery under either cold (CWI), thermoneutral water immersion (TWI) or control (CON) conditions. HRR indices (e.g., heart beats recovered in the first minute after exercise cessation, HRR(60)(s)) and vagal-related HRV indices (i.e., natural logarithm of the square root of the mean of the sum of the squares of differences between adjacent normal R-R intervals (Ln rMSSD)) were calculated for the three recovery conditions. HRR(60)(s) was faster in water immersion compared with CON conditions [30+/-9 beats min(-)(1) for CON vs. 43+/- 10 beats min(-)(1) for TWI (P=0.003) and 40+/-13 beats min(-)(1) for CWI (P=0.017)], while no difference was found between CWI and TWI (P=0.763). Ln rMSSD was higher in CWI (2.32+/-0.67 ms) compared with CON (1.98+/-0.74 ms, P=0.05) and TWI (2.01+/-0.61 ms, P=0.08; aES=1.07) conditions, with no difference between CON and TWI (P=0.964). Water immersion is a simple and efficient means of immediately triggering post-exercise parasympathetic activity, with colder immersion temperatures likely to be more effective at increasing parasympathetic activity.
本研究旨在探讨冷水和常温水中浸浴对运动后副交感神经再激活的影响，通过心率（HR）恢复（HRR）和心率变异性（HRV）指标推断。12 名男性在三种不同情况下进行了间歇性运动（全力 30 秒威格特测试，5 分钟坐姿恢复，然后进行 5 分钟亚最大强度跑步运动），随机在冷水（CWI）、常温水中浸浴（TWI）或对照（CON）条件下进行 5 分钟被动（坐姿）恢复。计算了三种恢复条件下的 HRR 指标（例如，运动停止后第 1 分钟内恢复的心跳数，HRR(60)(s)）和与迷走神经相关的 HRV 指标（即，相邻正常 R-R 间期差值的均方根的自然对数（Ln rMSSD））。与 CON 条件相比，水浸浴中的 HRR(60)(s)更快[CON 条件下为 30+/-9 次/min(-)(1)，TWI 条件下为 43+/-10 次/min(-)(1)（P=0.003），CWI 条件下为 40+/-13 次/min(-)(1)（P=0.017）]，而 CWI 和 TWI 之间没有差异（P=0.763）。CWI 中的 Ln rMSSD 高于 CON（1.98+/-0.74 ms，P=0.05）和 TWI（2.01+/-0.61 ms，P=0.08；aES=1.07）条件，CON 和 TWI 之间没有差异（P=0.964）。水浸浴是一种简单有效的触发运动后副交感神经活动的方法，较冷的浸浴温度可能更有效地增加副交感神经活动。
