The purpose of this study was to elucidate the effects of walking exercise based on the lactate threshold(LT)in a hypobaric environment on the body composition and energy metabolism in body weight reduction of athletes and obese adults. Before and after the training in experimental group I(EG I)of athletes, experimental group II(EG II)of obese adults and control group(CG), the following parameters were measured; body weight(BW), body composition and resting metabolic rate(RM)at 8 : 30-9 : 00a. m.. The subjects performed exercise under hypobaric environment(1500m)in EG I and II, and under normobaric environment in CG, for 60 min/day, 3 days/week for 4 weeks. BW in EG I and II after the training for 4 weeks was significantly lower than that before the training(p<0.01,p<0.05). Body composition of body fat, was also significantly decreased after the training(p<0.01,p<0.01). RM after the training in EG I and II was significantly higher than that before the training(p<0.05,p<0.05). Energy obtained from lipids was deterined based on the respiratory quotient at rest in EG I and II, which was observed to have increased after the training(p<0.01,p<0.05). These results indicate that walking exercise based on the LT in a hypobaric enironment may be a useful method for body weight reduction and exercise treatment for obesity.
