This study investigated the relative efficacy of postgame recovery modalities on jump height performance and subjective ratings of muscle soreness and muscle damage at 1, 18, and 42 hours after professional rugby league competition games. Twenty-one professional rugby league players performed 3 different postmatch recovery modalities: cold water immersion (CWI), contrast water therapy (CWT), and active recovery (ACT). The effects of the recovery treatments were analyzed with mixed modeling including a covariate (fatigue score) to adjust for changes in the intensity of each match on the postmatch values of the dependent variables of interest. Standardization of effects was used to make magnitude-based inferences, presented as mean with ±90% confidence limits. Cold water immersion and CWT clearly recovered jump height performance (CWI 2.3 ± 3.7%; CWT 3.5 ± 4.1%), reduced muscle soreness (CWI -0.95 ± 0.37; CWT -0.55 ± 0.37), and decreased creatine kinase (CWI -11.0 ± 15.1%; CWT 18.2 ± 20.1%) by 42 hours postgame compared with ACT. Contrast water therapy was however clearly more effective compared with CWI on the recovery of muscle soreness and creatine kinase by 42 hours postgame. Based on these findings, CWT recovery is recommended postmatch for team rugby sports.
本研究调查了赛后恢复方式对职业英式橄榄球联赛比赛后 1、18 和 42 小时跳跃高度表现和肌肉酸痛及肌肉损伤主观评分的相对效果。21 名职业英式橄榄球联赛运动员进行了 3 种不同的赛后恢复方式：冷水浸泡（CWI）、对比水疗（CWT）和主动恢复（ACT）。使用混合模型分析恢复治疗的效果，其中包括协变量（疲劳评分），以调整每个比赛的强度变化对感兴趣的因变量的赛后值。采用标准化效应进行基于幅度的推断，以平均值表示，置信区间为 90%。与 ACT 相比，冷水浸泡和 CWT 可明显恢复跳跃高度表现（CWI 2.3 ± 3.7%；CWT 3.5 ± 4.1%）、减轻肌肉酸痛（CWI -0.95 ± 0.37；CWT -0.55 ± 0.37）和肌酸激酶（CWI -11.0 ± 15.1%；CWT 18.2 ± 20.1%）至比赛后 42 小时。然而，与 CWI 相比，CWT 在比赛后 42 小时对肌肉酸痛和肌酸激酶的恢复效果更为明显。基于这些发现，建议在赛后使用 CWT 恢复。
