Effects of endurance training and heat acclimation on psychological strain in exercising men wearing protective clothing

摘要

Two experiments examined the influences of endurance training and heat acclimation on ratings of perceived exertion (RPE) and thermal discomfort (RTD) during exercise in the heat while wearing two types of clothing. In experiment 1, young men underwent 8 weeks of physical training [60-80/100 of maximal aerobic power (VO_2max) for 30-45 min day~-1, 3-4 days week~-1 at 20-22 deg. C dry bulb (db) temperature] followed by 6 days of heat acclimation [45- 55/100 Vo_2max for 60 min day~-1 at 40 deg. C ab, 30/100 relative humidity (rh)] (n = 7) or corresponding periods of control observation followed by heat acclimation (n = 9).
