【摘要】：研究目的:高温高湿环境是包括奥运会在内的各项大型赛事都不可避免的环境问题,而恢复阶段作为训练和比赛中至关重要的一个阶段,对于运动员保持良好的机能状态以应对接下来的训练和比赛都显得举足轻重。训练和比赛后的冷疗恢复是一项可以帮助运动员既抵御高温高湿热压力又能快速恢复的新兴物理恢复手段。本文旨在比较研究不同冷疗对高温高湿环境下自行车运动后生理指标影响,探索合理的恢复方法。研究方法:本实验采用随机分组设计,12名男性(平均年龄22.08±2.02岁)进行三次冷疗干预试验,即空白对照(CON)、冷疗(CWI)和冷热交替疗法(CWT),每次间隔7天。同一名受试者不同干预方式形成自身对照。受试者进入温度为35℃-38℃,湿度为60%-70%的高温高湿环境中进行递增负荷至力竭的功率自行车运动后,立即进行冷疗干预15min。实验中采集相关生理指标和运动成绩,数据结果采用SPSS23.0统计软件进行分析。研究结果:1.恢复结束后,与CON组相比,CWT组心率平均降低7次/min,CWI组心率平均降低5次/min,没有显著性差异(P0.05)。2.恢复结束后,与CON组相比,CWT组核心温度没有明显变化,CWI组核心温度平均降低0.3℃,表现出了显著性差异(P0.05)。3.恢复至第5min时,CWI组比CON组降低了0.7℃,表现出显著性差异(P0.05)。在恢复至第8min时,CWT组比CON组降低了0.7℃,表现出了显著性差异(P0.05)。其他时刻各组之间未表现出显著性差异(P0.05)。4.在恢复的第13min和恢复结束后,与CON组相比,CWT组血乳酸分别平均降低了1.7mmol/L和1.9mmol/L,均表现出了非常显著性差异(P0.001)。5.Omega Wave测试表明受试者机能状态反应各不相同,没有统一规律。研究结论与建议:1.冷疗可以显著降低核心温度;冷疗及冷热交替疗法对于皮肤表面温度的影响表现为先下降后上升;运动后进行冷热交替疗法相比于冷疗,血乳酸的恢复速度更快。2.冷疗与冷热交替疗法对于恢复阶段心率、血氧饱和度以及机体综合指标的恢复没有明显效果。3.建议在恢复阶段针对不同个体设计不同恢复方案,并对室温进行严格掌控。使之保持在合理区间。
[Abstract]:Research objective: high temperature and high humidity environment is an inevitable environmental problem in all major events, including the Olympic Games, and the recovery stage is a crucial stage in training and competition. For the athletes to maintain a good state of function to cope with the next training and competition are important. Cold therapy recovery after training and competition is a new physical recovery method which can help athletes to resist high temperature, high humidity and heat pressure as well as to recover quickly. The purpose of this paper is to compare the effects of different cold therapy on the physiological indexes of bicycle under high temperature and high humidity, and to explore a reasonable recovery method. Methods: 12 male subjects (mean age 22.08 卤2.02 years) were randomly divided into two groups to undergo three cold therapy intervention trials, namely, blank control group (Conn), cold therapy (CWI) and alternate cold and heat therapy (CWTT), with a 7-day interval. The same subject was self-controlled by different intervention methods. The subjects entered the temperature range of 35 鈩，
