The purpose of this study is to evaluate the effects of air velocity on the human thermal responses during physical exercise. The experiments were carried out in a climatic chamber at different air temperatures ranging from 20℃ to 35℃ and for air velocities of 0.2 m/s, 1.4 m/s and 2.8 m/s. The relative humidity was 50% and the mean radiant temperature was equal to the ambient air temperature. The subjects were six collegiate females and they wore a short-sleeved cotton T shirts and cotton shorts. They stayed for 60 minutes and they took physical exercise for 40 minutes. The exercise intensities were 25 W and 50 W. The physiological responses, i.e., skin temperatures at 12 points, rectal temperature, heart rate, metabolic rate and weight loss were measured. Thermal sensation and comfort sensation were asked. Mean skin temperature, heat balance and skin wettedness were calculated. The effects of air velocities on the thermal responses were expressed in the change of air temperature.
