The purpose of this study is to elucidate the effects of walking exercise based on the lactate threshold (LT) in a hypobaric environment on the energy expenditure of post-exercise in obese adults. The subjects walked for 60 minutes on a treadmill in two environments : a hypobaric environment (HE) at 1500 m simulated altitude, and normobaric environment (NE) at sea level. During and post exercise in HE and NE, comparisons were made of total energy expenditure, resting metabolic rate (RM) after fasting for 15 hours (the following morning), energy expenditure deduced from carbohydrate and fat. Total energy expenditure and energy obtained from carbohydrate and fat during exercise did not differ between HE and NE. Total energy expenditure at 30 and 60 minutes post-exercise in HF were significantly higher than those in NE(p<⇒<0.05,p<⇒<0.05). The energy expenditure obtained from fat at 60 minutes in HE was significantly higher than that in NE (p<⇒<0.05). The RM in HE was significantly higher than that in non-exercise (p<⇒<0.01). The energy expenditure obtained from fat in HE was significantly higher than that in NE (p<⇒<0.01). These results suggest that walking exercise based on the LT in a hypobaric environment enhances RM at least 15 hours, and elevates the rate of fat utilization.
