Effects of fatigue recovery by HSP expression and possibility of effective muscular strength

本研究的目的是研究不同类型的沐浴对综合竞技游泳运动员睡眠反应的影响。本研究以12名健康的大学生竞技游泳运动员为对象。受试者接受两种不同的沐浴；全身浸泡浴（WBIB）和淋浴浴（SB）。两次洗澡的水温都是42摄氏度。为了测量睡眠-觉醒周期，使用加速度计（Lifecorder GS， SUZUKEN, Japan）。睡眠-觉醒数据由昼夜节律分析软件（SleepSign Act, KISSEI COMTEC，日本）分析。分析的睡眠变量为床上时间（TIB）、睡眠周期时间（SPT）、总睡眠时间（TST）、睡眠开始后清醒时间（WASO）、睡眠效率（SE）、睡眠潜伏期（SL）、睡眠开始时间、清醒开始时间和离床潜伏期（BOL）。WBIB组的SL明显短于SB组（p < 0.05）， SE明显高于SB组（p < 0.05）， SPT明显长于SB组（p < 0.05），提示WBIB可使体核温度升高到一定程度，可能引起深度睡眠。在WBIB之后的睡眠似乎对从疲劳中恢复非常有用。

The purpose of this study was to examine the effect of different types of bathing on responses to sleep in colligatecompetitive swimmers. Twelve healthy colligate competitive swimmers were participated inthis study. The subjects were taken two different types of bathing; whole body immersion bathing (WBIB) and shower bathing (SB). The water temperature of both bathing was 42 degrees Celsius. To measure the sleep-wake cycle, accelerometers (Lifecorder GS, SUZUKEN, Japan) was used. The sleep - wake data were analysed by circadian rhythm analysis software (SleepSign Act, KISSEI COMTEC, Japan). Analysed a sleep variables were time in bed (TIB), sleep period time (SPT), total sleep time (TST), wake time after sleep onset(WASO), sleep efficiency (SE), sleep latency (SL), time of sleep onset, time of wake onset, and bed out latency (BOL). SL was significantly shorter (p < .05) in WBIB than that in SB. SE was significantly higher (p < .05) in WBIB than that in SB. SPT was significantly longer (p < .05) in WBIB than that in SB. Therefore, these results suggest that as WBIB could raise body core temperature enough, this hyperthermia may cause a deep sleep. The sleep after the WBIB seems to be extremely useful in the recovery from fatigue.
