The purpose of this study was to elucidate the effect of walking exercise basedon the lactate threshold (LT) in hypobaric and normobaric environments for body weight reduction in obese adults. For 3 days/week for 4 weeks of walking exercise, an experimental group (EG) of obese adults walked 1 day under hypobaric environment (1500m) and the remaining 2 days under normobaric environment. A control group (CG) of obese adults exercised under a normobaric environment for 3 days/week. All the subjects walked for 60 minutes on a treadmill. Before and after the training in EG and CG, the following parameters were measured ;body weight (BW), % body fat and resting metabolic rate (RMR) at 08:30-09:00 a.m.. BW and % body fat in EG and CG did not deffer between before and after 4 weeks. RMR was also not significantly different. However, the different magnitudes of the mean values between before and after 4 weeks in EG tended to be greater than that in CG. Energy obtained from lipids was determined based on the respiratory quotient at rest in EG, which was tended to have increased after the training. The improvement of obesity in EG may be more clearly induced to continue over a longer period of time than normobaric environment alone in CG. These results indicate that walking exercise based on the LT in hypobaric and normobaric environments may be a useful method for body weight reduction and exercise treatment for obesity.
