This study investigated the effects of cold water immersion on recovery from anaerobic cycling. Seventeen (13 male, 4 female) active subjects underwent a crossover, randomised design involving two testing sessions 2 - 6 d apart. Testing involved two 30-s maximal cycling efforts separated by a one-hour recovery period of 10-min cycling warm-down followed by either passive rest or 15-min cold water immersion (13 - 14 degrees C) with passive rest. Peak power, total work and postexercise blood lactate were significantly reduced following cold water immersion compared to the first exercise test and the control condition. These variables did not differ significantly between the control tests. Peak exercise heart rate was significantly lower after cold water immersion compared to the control. Time to peak power, rating of perceived exertion, and blood pH were not affected by cold water immersion compared to the control. Core temperature rose significantly (0.3 degrees C) during ice bath immersion but a similar increase also occurred in the control condition. Therefore, cold water immersion caused a significant decrease in sprint cycling performance with one-hour recovery between tests.
本研究调查了冷水浸泡对无氧骑行恢复的影响。17名（13名男性，4名女性）活跃受试者采用交叉随机设计，进行了两次间隔2 - 6天的测试。测试包括两次30秒的最大骑行努力，中间有1小时的恢复期，先进行10分钟的骑行放松，然后要么是被动休息，要么是15分钟的冷水浸泡（13 - 14摄氏度）并被动休息。与第一次运动测试和对照条件相比，冷水浸泡后峰值功率、总功和运动后血乳酸显著降低。对照测试之间这些变量没有显著差异。与对照相比，冷水浸泡后运动峰值心率显著降低。与对照相比，冷水浸泡对达到峰值功率的时间、主观用力程度评分和血液pH值没有影响。冰浴浸泡期间核心温度显著升高（0.3摄氏度），但对照条件下也出现了类似的升高。因此，冷水浸泡导致短跑骑行表现显著下降，测试之间有1小时的恢复时间。
