The purpose of this study was to develop a body characteristic index (BCI) based on the distribution of maximal oxygen uptake per body mass (VO2max/mass), body surface area per body mass (BSA/mass), and percentage of body fat (Fat%) to evaluate the relative level of individual physiological responses to heat strain in a group of workers. BCI was based upon the data obtained from 10 males and 10 females exercising for 60 min on a treadmill at 2 relative exercise intensities of 25% and 45% VO2max in mild, warm wet, and hot dry climate condition, separately. BCI was developed into 2 formulas, which were proved to be better predictors for heat strain responses than each individual characteristic, and more sensitive than body type to describe the distributions of individual characteristics and distinguish the differences in physiological responses to heat.
本研究的目的是基于每体重最大摄氧量（VO2max/体重）、每体重体表面积（BSA/体重）和体脂百分比（Fat%）的分布情况，开发一种身体特征指数（BCI），以评估一组工人个体对热应激的相对生理反应水平。BCI基于分别在温和、温暖潮湿和炎热干燥气候条件下，10名男性和10名女性以25%和45%VO2max这两种相对运动强度在跑步机上运动60分钟所获得的数据。BCI被开发为2个公式，事实证明，与每个单独的特征相比，它们是热应激反应更好的预测指标，并且比体型更敏感，能够描述个体特征的分布并区分对热的生理反应差异。
