摘要

目的

采用经典热习服训练方法复合缺氧训练以探索提升机体耐热能力的有效方法。

方法

在温度33 ℃以上、湿度大于70%的湿热条件下，以2018年某部队60名经严格筛查的男性健康志愿者为对象，进行为期12 d的热习服训练和测试。60名志愿者分为3组，分别为对照组、热习服组和缺氧训练复合热习服组，每组20名。采集热习服前后耳温、心率、出汗量、心肺功能、综合感受评分、生理紧张指数(physiological strain index，PSI)、最大摄氧量(maximal oxygen uptake

)、心率为170次/min时的体力工作能力(physical work capacity at heart rate of 170 beats per minute

PWC

170

)进行耐热能力的评估。

结果

与对照组相比，热习服组以及缺氧复合热习服组基础耳温、耐热测试后的耳温均显著下降(

0.05)，基础心率以及耐热测试后的心率均显著下降(

0.05)；PSI与呼吸频率也显著降低(

0.05)；出汗量、VO

0.05)，并且PSI与呼吸频率也出现显著降低(

0.05)。与热习服组相比，缺氧复合热习服组的出汗量、VO

Abstract

Objective

To explore an effective method to improve the heat resistance of the body by combining classic heat acclimation and hypoxia training.

Methods

In 2018

a total of 60 healthy male volunteers who were strictly screened from a troop were recruited in this study. They were equally divided into control group

heat acclimation group

and hypoxia training combined heat acclimation group. Then they were trained for 12 d under a damp heat condition (temperature

33 ℃ and humidity

70%). Their ear temperature

heart rate

sweating amount

cardiopulmonary function

comprehensive feeling scores

physiological strain index (PSI)

maximal oxygen uptake (VO

2max

)

and physical work capacity at heart rate of 170 beats per minute (PWC

170

) were tested and evaluated before and after heat acclimation.

Results

Compared with the control group

the heat acclimation group and the combination group had significantly lower basic ear temperature and the ear temperature after heat test (

0.05)

decreased basic and post-test heart rate (

0.05)

and reduced PSI and respiratory rate (

0.05)

but increased sweating amount

2max

PWC

170

maximum cardiac output

oxygen consumption/maximal heart rate

maximum CO

emission

and maximum lung ventilation (

0.05). What's more

the heart rate and ear temperature after heat test were obviously lo

wer in the combination group than the heat acclimation group (

0.05)

so were PSI and respiratory rate (

0.05). But the former group had notably higher sweating amount

2max

PWC

170

maximum cardiac output

oxygen consumption/maximal heart rate

maximum CO

emission

and maximum lung ventilation than the latter group (

0.05).

Conclusion

Based on the classic heat acclimation

combination of hypoxia training can promote heat acclimation more effectively.
