湿热环境训练的人体温度安全指标简

目的：通过分析文献,建立回归方程,结合实验记录综合确定湿热环境训练安全上限,保证训练安全,并将之封装成程序,以利推广.方法：选取30名男性志愿者为受试者,年龄在18～23岁,经体检和体能测试均合格.每次训练前后测量其人体温度相关指标（包括皮肤5点温度、肛温以及由此计算出的平均体温、积热指数BHSI）.与文献报道对比,确定其准确度,通过多元回归方程分析建立相关模型,并使用Visual Basic6.0软件封装安全上限结论.结果：平均体温和BHSI超过文献报道的例数均超过其置信区间;平均体温、BHSI均与环境的温度、湿度,以及劳动作业强度有关.为此建立了回归方程.结论：综合分析文献报道与本实验,提出在温热环境训练的3条安全上限.

Research on Body Temperature Used to Evaluate Safety of Training in Hot and Humid Environment

Purpose： Purpose： We try to define the upper limit to safety of training in hot and humid environment by analyzing litera- tures, founding regression equation and sorting our data in order to ensure training safety. We made a program for spreading its us- age. Methods： We collected data of body temperature （including 5 -dots temperature on skin, rectal temperature and average body temperature, and BHSI which were calculated） of 30 male volunteers （age： 18- 23y, both health examination and physical agility test are all right） before and after each time of training. Result： average body temperature and BHSI are over the upper limit report- ed, while rectal temperature is below it. So we built the regression equation. Conclusion： After comprehensive analysis, we put for- ward the upper limit for safety.
