A physiological strain index to evaluate heat stress.
A physiological strain index (PSI), based on rectal temperature (Tre) and heart rate (HR), capable of indicating heat strain online and analyzing existing databases, has been developed. The index rates the physiological strain on a universal scale of 0-10. It was assumed that the maximal Tre and HR rise during exposure to exercise heat stress from normothermia to hyperthermia was 3°C (36.5-39.5...

متن کاملCan gender differences during exercise-heat stress be assessed by the physiological strain index?
A physiological strain index (PSI) based on rectal temperature (Tre) and heart rate (HR) was recently suggested to evaluate exercise-heat stress. The purpose of this study was to evaluate PSI for gender differences under various combinations of exercise intensity and climate. Two groups of eight men each were formed according to maximal rate of O2 consumption (V˙o 2 max). The first group of men...
متن کاملAging and assessment of physiological strain during exercise-heat stress.
The purpose of this study was to evaluate the physiological strain index (PSI) for different age groups during exercise-heat stress (EHS). PSI was applied to three different databases. First, from young and middle-age men (21 +/- 2 and 46 +/- 5 yr, respectively) matched (n = 9 each, P > 0.05) for maximal aerobic power. Subjects were heat acclimated by daily treadmill walking for two 50-min bout...
متن کاملHyperthermia during exercise – a double-edged sword
An excessive elevation in body temperature is known to decrease exercise performance. The physiological mechanisms involved with hyperthermia-induced fatigue include central nervous system dysfunction and cardiovascular instability. Conversely, a moderate increase in body temperature has been shown to actually improve exercise performance. Asmussen and Boje reported that sprint performance impr...
