A physiological strain index (PSI) based on rectal temperature (Tre) and heart rate was recently suggested to evaluate exercise/heat stress. This review summarizes the development of PSI which was evaluated from seven different databases during the last three years. PSI was developed from data obtained from man performing exercise in the heat and from a separate database of man wearing protective clothing and exercising in hot-dry and hot-wet environmental conditions. This index was also evaluated for heat strain associated with hypohydration and for exercise/heat stress and gender. In addition, PSI was adjusted for values in rats, and could be used to assess the individual roles played by heat acclimation and exercise training in rats. This simple to use index scales strain to a range of 0-10, can be used on-line or during data analysis, and includes the ability to depict rest and recovery periods. The PSI has the potential to be widely accepted and to serve universally.
最近有人提出基于直肠温度（Tre）和心率的生理应激指数（PSI）来评估运动/热应激。本综述总结了过去三年从七个不同数据库评估的PSI的发展情况。PSI是根据在热环境中进行运动的男性的数据以及一个单独的数据库开发的，该数据库涉及穿着防护服在干热和湿热环境条件下运动的男性。该指数还针对与低水合作用相关的热应激以及运动/热应激和性别进行了评估。此外，对大鼠的数值进行了PSI调整，可用于评估热适应和运动训练在大鼠中所起的个体作用。这个易于使用的指数将应激程度分为0 - 10的范围，可在线使用或在数据分析期间使用，并且具备描绘休息和恢复阶段的能力。PSI有潜力被广泛接受并普遍应用。
