背景训练恢复对于适应和表现至关重要，对于避免累积的疲劳和过度训练相关的症状至关重要。使用冷水浸泡(CWI)作为恢复策略是很常见的；然而，其使用背后的生理和生化原理仍不清楚。方法12名男子橄榄球运动员参加了为期3周的交叉试验，在60min的高强度训练后，立即进行14℃温水浸泡(WWI)、30℃温水浸泡(WWI)或被动对照(CON)恢复干预15min。记录运动后体温和恢复干预的主观评分，并在24小时后进行5x40m重复冲刺方案。结果与WWI(ES 1.04+/-0.84)和CON(ES 1.44+/-0.84)相比，CWI显著降低了融合后的核心体温(ES范围为1.05-3.21)，并提高了随后的冲刺成绩。融合后60分钟体温下降的程度(r=0.6948；p=0.0121)和恢复干预的主观评分(r=0.5886；p=0.0441)都与随后的冲刺成绩有关。当这两个因素综合在一起时，存在很强的线性相关性(r=0.7743；p=0.0031)。结论生理和心理指标的组合可以更好地反映随后的表现，表明个体知觉在促进训练恢复中起着重要作用。
Background Training recovery is vital for adaptation and performance, and to avoid cumulative fatigue and symptoms associated with overtraining. The use of cold-water immersion (CWI) as a recovery strategy is common; however, the physiological and biochemical rationale behind its use remains unclear. This study aimed to assess the relationship between body temperature responses to water immersion and individual perception of recovery, with subsequent exercise performance.Methods Twelve male rugby players participated in a 3-week cross-over trial where an intense 60 min conditioning session was followed immediately by 15 min of either 14 degrees C CWI, 30 degrees C warm-water immersion (WWI) or passive control (CON) recovery intervention. Postexercise body temperatures and subjective ratings of the recovery intervention were recorded and subsequently related to performance in a 5x40 m repeated sprint protocol undertaken 24 h later.Results CWI induced large reductions in core body temperature postimmersion (effect size (ES) range 1.05-3.21) and improved subsequent sprint performance compared to WWI (ES 1.04 +/- 0.84) and CON (ES 1.44 +/- 0.84). Both the degree of temperature decrease at 60 min postimmersion (r=0.6948; p=0.0121) and the subjective rating of the recovery intervention (r=0.5886; p=0.0441) were related to subsequent sprint performance. A very strong linear correlation was observed when these two factors were integrated (r=0.7743; p=0.0031).Conclusion A combination of physiological and psychological indices provides an improved indication of subsequent performance and suggests an important role of individual perception in enhancing training recovery.
