요약1 The purpose of this study was to compare the physiological responses according to environmental temperature variations during 60 min submaximal exercise between normal and obese groups, for the scientific approach to the optimal exercise prescription in obese subjects. The subjects consisted of male college-aged students, who were divided into two groups, such as one group of 6 obese subjects (body fat ratio higher than 25%) and another group of 6 normal subjects. Changes of heart rate, body temperature, and blood lactate were measured during 60 min submaximal exercise on intensity corresponding to 60%VO2max utilizing bicycle ergometer and recovery phase in different environmental condition of normal (20 1oC, humidity 65 2%), heat (40 1oC, humidity 60 2%), and cold (6 1oC, humidity 30 2%), respectively. Both groups showed the higher values of heart rate during exercise as compared to resting values in all conditions. Especially, heat condition induced to the highest response of heart rate and body temperature, but cold condition arised the blunting tendency of the heart rate increase and the steady state of body temperature response in both groups. Both groups showed the increase of blood lactate concentration during exercise as compared to resting values in all conditions, but it could not showed the upcurve to 4 mM. This results imply that the exercise intensity corresponding to 60%VO2max in submaximal exercise could be regard as optimal exercise intensity in all condition for the both groups, but it could be suggested obese subjects were required the additional water intake and the careful treatment during exercise in heat condition.
