尽管冷水浸泡(CWI)是最广泛使用的运动后策略之一,以加速恢复过程,CWI的益处可能与安慰剂效应相关.这项研究旨在比较CWI和安慰剂干预对拉夫堡间歇穿梭试验(LIST)后恢复时间的影响。在一个随机的,平衡,交叉研究,十二名半职业足球运动员(年龄21.1±2.2岁,体重72.4±5.9kg,高度174.9±4.6厘米,V•O2max56.1±2.3mL/min/kg)完成LIST,然后是CWI(在11°C下15分钟),安慰剂(恢复PLA饮料),和被动恢复(休息)在三个不同的星期。肌酸激酶(CK),C反应蛋白(CRP),尿酸(UA),延迟性肌肉酸痛(DOMS),深蹲跳跃(SJ),反运动跳跃(CMJ),10米冲刺(10毫秒),在基线以及LIST后24和48小时评估20米冲刺(20mS)和重复冲刺能力(RSA)。与基线相比,在所有条件下,CK浓度在24小时均较高(p<0.01),而仅在CWI和Rest条件下,CRP在24小时较高(p<0.01)。与Pla和CWI条件相比,休息条件在24和48小时时的UA较高(p<0.001)。与CWI和Pla条件相比,24小时休息条件下的DOMS评分更高(p=0.001),并且仅在48小时时达到Pla条件(p=0.017)。在休息条件下的LIST后,SJ和CMJ性能显着下降(24小时:-7.24%,p=0.001和-5.45%,p=0.003;48h:-9.19%,p分别<0.001和-5.70%p=0.002),但在CWI和Pla条件下并非如此。与CWI和Rest条件相比,Pla在24小时时的10mS和RSA性能较低(p<0.05),而20mS时间没有观察到显著变化。这些数据表明CWI和Pla干预在肌肉损伤标志物的恢复动力学和身体表现方面比休息条件更有效。此外,可以解释CWI的有效性,至少在某种程度上,通过安慰剂效应。
Although cold water immersion (CWI) is one of the most widely used post-exercise strategies to accelerate recovery processes, the benefits of CWI may be associated with placebo effects. This study aimed to compare the effects of CWI and placebo interventions on time course of recovery after the Loughborough Intermittent Shuttle Test (
LIST). In a randomized, counterbalanced, crossover study, twelve semi-professional soccer players (age 21.1 ± 2.2 years, body mass 72.4 ± 5.9 kg, height 174.9 ± 4.6 cm, V ˙ O2max 56.1 ± 2.3 mL/min/kg) completed the
LIST followed by CWI (15 min at 11°C), placebo (recovery Pla beverage), and passive recovery (Rest) over three different weeks. Creatine kinase (CK), C-reactive protein (CRP), uric acid (UA), delayed onset muscle soreness (DOMS), squat jump (SJ), countermovement jump (CMJ), 10-m sprint (10 mS), 20-m sprint (20 mS) and repeated sprint ability (RSA) were assessed at baseline and 24 and 48 h after the
LIST. Compared to baseline, CK concentration was higher at 24 h in all conditions (p < 0.01), while CRP was higher at 24 h only in CWI and Rest conditions (p < 0.01). UA was higher for Rest condition at 24 and 48 h compared to Pla and CWI conditions (p < 0.001). DOMS score was higher for Rest condition at 24 h compared to CWI and Pla conditions (p = 0.001), and only to Pla condition at 48 h (p = 0.017). SJ and CMJ performances decreased significantly after the
LIST in Rest condition (24 h: -7.24%, p = 0.001 and -5.45%, p = 0.003 respectively; 48 h: -9.19%, p < 0.001 and -5.70% p = 0.002 respectively) but not in CWI and Pla conditions. 10 mS and RSA performance were lower for Pla at 24 h compared to CWI and Rest conditions (p < 0.05), while no significant change was observed for 20 mS time. These data suggests that CWI and Pla intervention were more effective than the Rest conditions in recovery kinetics of muscle damage markers and physical performance. Furthermore, the effectiveness of CWI would be explained, at least in part, by the placebo effect.
