It has been suggested that heat exposure prior to exercise could induce changes in anaerobic exercise. Therefore, the purpose of this study was to observe the effects of high temperature heat exposure prior to an anaerobic test. Twenty-one men (age: 19.76 ± 1.22 years; height: 1.69 ± 0.12 m; weight: 67.89 ± 11.78 kg) voluntarily participated in this investigation. All of them performed two Wingate tests, vertical jump and macronutrient intake control. On the first day, the test was performed under normal environmental conditions. On the second day, it was performed in a similar way, but with previous exposure to heat at high sauna temperatures (15 min; 100 ± 2 °C). There were no differences in the vertical jump and macronutrient intake. However, the results showed an improvement in power (W) ( < 0.05), relative power (W/kg) ( < 0.01) and revolutions per minute ( < 0.05) 10 s after the start of the test. There was also an increase in thigh ( < 0.01) and skin temperature ( < 0.01) with pre-heat exposure. The results obtained suggest that this pre-exercise protocol could improve power in short and intensive actions.
有人认为，运动前的热暴露会导致无氧运动发生变化。因此，本研究的目的是观察高温热暴露对无氧测试前的影响。21 名男性（年龄：19.76±1.22 岁；身高：1.69±0.12m；体重：67.89±11.78kg）自愿参加了这项研究。他们都进行了两次蛙跳测试、垂直跳跃和宏量营养素摄入控制。第一天，在正常环境条件下进行测试。第二天，以类似的方式进行测试，但之前在高温桑拿（15 分钟；100±2°C）中暴露。垂直跳跃和宏量营养素摄入没有差异。然而，结果显示，在测试开始后 10 秒，功率（W）（<0.05）、相对功率（W/kg）（<0.01）和每分钟转速（rpm）（<0.05）有所提高。股四头肌（<0.01）和皮肤温度（<0.01）也随着预热暴露而升高。研究结果表明，这种运动前方案可以提高短时间、高强度运动的力量。
