在锦标赛场景中，运动员在相对较短的时间段内进行多次比赛是一种常见的要求，没有足够的恢复时间不允许完全恢复身体表现。本研究旨在更好地了解运动员在锦标赛中所经历的生理压力，以及常用的恢复策略冷水浸泡（CWI）如何影响这些标志物。21名受过训练的男性游戏玩家（年龄19 +/- 2;体重78.0 +/- 8.8 kg）被随机分为CWI组（n = 11）或对照组（n = 10）。为了模拟比赛，参与者在五天内完成了三次拉夫堡间歇穿梭测试（LIST）。在特定时间点使用短跑表现、肌肉功能、肌肉酸痛的标志物和损伤（肌酸激酶，CK）、炎症（IL-6和C-反应蛋白）和氧化应激（脂质氢过氧化物和6种脂溶性抗氧化剂的活性）的生化标志物评估恢复。模拟锦标赛与某些（但不是全部）生理应激和恢复标志物的扰动相关。冷水浸泡与最终LIST后24小时短跑速度恢复的改善相关（ES = 0.83 +/- 0.59; p = 0.034），并减弱了LIST 3前后CK的流出（p <0.01）。比赛的情况下，导致生理压力的升级，在主要的，冷水浸泡是无效的管理。这些数据表明，CWI是无害的，并提供有限的好处，在减弱比赛的情况下经历的有害影响。
It is a common requirement in tournament scenarios for athletes to compete multiple times in a relatively short time period, with insufficient recovery time not allowing full restoration of physical performance. This study aimed to develop a greater understanding of the physiological stress experienced by athletes in a tournament scenario, and how a commonly used recovery strategy, cold water immersion (CWI), might influence these markers. Twenty-one trained male games players (age 19 +/- 2; body mass 78.0 +/- 8.8 kg) were randomised into a CWI group (n = 11) or a control group (n = 10). To simulate a tournament, participants completed the Loughborough Intermittent Shuttle Test (LIST) on three occasions in five days. Recovery was assessed at specific time points using markers of sprint performance, muscle function, muscle soreness and biochemical markers of damage (creatine kinase, CK), inflammation (IL-6 and C-Reactive Protein) and oxidative stress (lipid hydroperoxides and activity of 6 lipid-soluble antioxidants). The simulated tournament was associated with perturbations in some, but not all, markers of physiological stress and recovery. Cold water immersion was associated with improved recovery of sprint speed 24 h after the final LIST (ES = 0.83 +/- 0.59; p = .034) and attenuated the efflux of CK pre- and post-LIST 3 (p < .01). The tournament scenario resulted in an escalation of physiological stress that, in the main, cold water immersion was ineffective at managing. These data suggest that CWI is not harmful, and provides limited benefits in attenuating the deleterious effects experienced during tournament scenarios.
