The Efieds of Walking Exercise in High Altitude (Hypobaric Hypoxic Environment) and RunneMnotion-resjwnse-type Training Systems for Weight Reductionin Obese A&ifcs

本研究旨在探讨常压和常压环境下步行锻炼对肥胖成人静息代谢率(RMR)和体成分的影响。在12周的步行锻炼中，肥胖组(EG)每周步行3天，其中1天在减压环境下行走，其余2天在常压环境下步行。对照组(CG)肥胖成年人在常压环境下每周锻炼3天。所有受试者在跑步机上步行60分钟，在减压环境下步行，总能量消耗增加至少15小时(第二天早上)。训练组和对照组训练后体重均显著低于训练前。训练后，训练组和对照组的体脂组成均显著下降。实验组训练后RMR显著高于训练前。训练后，实验组和对照组从HPIDs中获得的能量有所增加。随着RMR的增加，实验组的体重减轻可能比仅在常压环境下更明显地持续更长的时间。这些结果表明，结合常压和常压环境下的步行锻炼可能是一种有效的减肥和运动治疗肥胖症的方法。

The purpose of this study was to elucidate the effects of walking exercisein hypobaric and normobaric environmentson the resting metabolic rate (RMR) and the body composition in obese adults. For 3 days per week during 12 weeks ofwalking exercise, an experimental group (EG) of obese adults walked 1 day under a hypobaric environment and the remaining 2 days under a normobaric environment A control group (CG) of obese adults exercised under anormobaric environment for 3 days per week. All the subjects walked for 60minutes on a treadmill Walking exercise in a hypobaricenvironment enhancedtotal energy expenditure at least 15 hours (the following morning). The body weight in EG andCG after the training was significantly lower than that before the training. The composition of body fat in EG and CG decreased significantly after the training. RMR after the training in EG was significantly higher than that before the training. Energy obtained from Hpids in EG and CG was observed to have increased after the training. The body weight reduction with the increase in RMR in EG may be more clearly induced to continue over a longer period of time than the normobaric environment alone hi CG. These results indicate that the combination of walking exercise hi hypobaric and normobaric environments may be a useful method for body weight reduction and exercise treatment for obesity.
