This study examined the effect of contrast water therapy (CWT) on the physiological and functional symptoms of delayed onset muscle soreness (DOMS) following DOMS-inducing leg press exercise. Thirteen recreational athletes performed 2 experimental trials separated by 6 weeks in a randomized crossover design. On each occasion, subjects performed a DOMS-inducing leg press protocol consisting of 5 x 10 eccentric contractions (180 seconds recovery between sets) at 140% of 1 repetition maximum (1RM). This was followed by a 15-minute recovery period incorporating either CWT or no intervention, passive recovery (PAS). Creatine kinase concentration (CK), perceived pain, thigh volume, isometric squat strength, and weighted jump squat performance were measured prior to the eccentric exercise, immediately post recovery, and 24, 48, and 72 hours post recovery. Isometric force production was not reduced below baseline measures throughout the 72-hour data collection period following CWT ( approximately 4-10%). However, following PAS, isometric force production (mean +/- SD) was 14.8 +/- 11.4% below baseline immediately post recovery (p < 0.05), 20.8 +/- 15.6% 24 hours post recovery (p < 0.05), and 22.5 +/- 12.3% 48 hours post recovery (p < 0.05). Peak power produced during the jump squat was significantly reduced (p < 0.05) following both PAS (20.9 +/- 13.4%) and CWT (12.8 +/- 8.0%), with the mean reduction in power for PAS being marginally (not significantly) greater than for CWT (effect size = 0.76). Thigh volume measured immediately following CWT was significantly less than PAS. No significant differences in the changes in CK were found; in addition, there were no significant (p > 0.01) differences in perceived pain between treatments. Contrast water therapy was associated with a smaller reduction, and faster restoration, of strength and power measured by isometric force and jump squat production following DOMS-inducing leg press exercise when compared to PAS. Therefore, CWT seems to be effective in reducing and improving the recovery of functional deficiencies that result from DOMS, as opposed to passive recovery.
本研究考察了对比水疗法（CWT）对诱发延迟性肌肉酸痛（DOMS）的腿部推举运动后DOMS的生理和功能症状的影响。13名休闲运动员采用随机交叉设计，进行了两次间隔6周的实验性试验。每次试验时，受试者进行一项诱发DOMS的腿部推举方案，包括以1次最大重复量（1RM）的140%进行5组每组10次的离心收缩（组间恢复180秒）。随后是15分钟的恢复期，期间采用CWT或不进行干预，即被动恢复（PAS）。在离心运动前、恢复后即刻、恢复后24小时、48小时和72小时测量肌酸激酶浓度（CK）、疼痛感知、大腿体积、等长蹲举力量和负重纵跳蹲举表现。在CWT后的72小时数据收集期内，等长力产生未降至基线测量值以下（约4 - 10%）。然而，在PAS后，恢复后即刻等长力产生（平均值±标准差）比基线低14.8±11.4%（p < 0.05），恢复后24小时低20.8±15.6%（p < 0.05），恢复后48小时低22.5±12.3%（p < 0.05）。PAS（20.9±13.4%）和CWT（12.8±8.）后，纵跳蹲举期间产生的峰值功率均显著降低（p < 0.05），PAS的功率平均降低幅度略大于CWT（效应量 = 0.）。CWT后即刻测量的大腿体积显著小于PAS。未发现CK变化有显著差异；此外，各治疗组之间的疼痛感知也无显著（p > 0.01）差异。与PAS相比，对比水疗法与诱发DOMS的腿部推举运动后通过等长力和纵跳蹲举产生测量的力量和功率的较小降低及更快恢复相关。因此，与被动恢复相反，CWT似乎在减少和改善由DOMS导致的功能缺陷恢复方面有效。
