Abstract
The purpose of this study was to investigate the optimum muscle temperature required to maintain work performance with attenuation of heat stress. Nine male subjects (23±0.36 year) performed eight 8-sec bouts of maximal cycling exercise at a load intensity of 60% of their peak power output, with a 40-sec resting period between bouts, in a room maintained at 24.8±0.2°C and 52±1% relative humidity. The subjects worn trousers lined with tubes perfused water at 6°C, 17°C, 30°C or 44°C, and the target thigh muscle temperatures were 32°C (32.4±0.2°C), 34°C (34.4±0.2°C), 36°C (36.3±0.1°C) and 38°C (37.5±0.2°C), respectively. The peak power output from first to fourth bouts and the total work output during eight bouts were significantly greater at the 36°C and 38°C conditions than at the 32°C and 34°C conditions (p
