The aim of the present study was to examine the effect of exercise intervention in hypoxia as a novel treatment method for obesity in older men.
A total of 24 obese 65-70-year-old Korean men (66.5 ± 0.8 years) were randomly assigned to undergo hypoxic training (n = 12) or normoxic training (n = 12), and all participants carried out an exercise intervention composed of aerobic exercise on a treadmill (30 min) and bicycle (30 min), and resistance exercise (30-40 min) in normoxia, and 3000-m normobaric hypoxia separately for a total of 12 weeks, three times a week. Health-related dependent variables (body composition, physical fitness, pulmonary function and heart rate variability) were evaluated at pre- and post-exercise intervention.
Hypoxic training showed more improved body composition (bodyweight -5.68 vs -3.16 kg, %body fat -5.50 vs -1.97%, fat-free mass 2.09 vs 1.06 kg), physical fitness (chair sit-to-stand 5.67 vs 4.58, pegboard 3.58 vs 2.17, tandem test -1.74 vs -1.31 s, one leg standing 6.27 vs 3.71 s), pulmonary function (forced vital capacity 0.15 vs 0.02 L, forced expiratory volume in 1 s 0.23 vs 0.01 L, percent of forced expiratory volume in 1 s 0.87 vs 0.08, maximal voluntary ventilation 5.26 vs 2.22 L) and heart rate variability (high frequency 0.94 vs 0.19 ms , low frequency/high frequency -0.28 vs -0.08, salivary cortisol -0.13 vs -0.04 μg/dL) than normoxic training.
Compared with normoxic training, hypoxic training is a novel and successful health promotion method in obese older populations. Geriatr Gerontol Int 2019; 19: 311-316.
本研究旨在探讨在缺氧条件下进行运动干预作为一种治疗老年男性肥胖的新方法的效果。
共有 24 名肥胖的 65-70 岁韩国男性（66.5±0.8 岁）被随机分为缺氧训练组（n=12）和常氧训练组（n=12）。所有参与者均进行了运动干预，包括在常氧条件下进行跑步机（30 分钟）和自行车（30 分钟）有氧运动，以及阻力运动（30-40 分钟），并分别进行了 12 周的 3000 米常压低氧训练，每周 3 次。在运动干预前后评估健康相关的因变量（身体成分、体能、肺功能和心率变异性）。
缺氧训练组的身体成分（体重-5.68 比-3.16kg，%体脂-5.50 比-1.97%，去脂体重 2.09 比 1.06kg）、体能（坐站起 5.67 比 4.58，指板 3.58 比 2.17，串联测试-1.74 比-1.31s，单腿站立 6.27 比 3.71s）、肺功能（用力肺活量 0.15 比 0.02L，1 秒用力呼气量 0.23 比 0.01L，1 秒用力呼气量百分比 0.87 比 0.08，最大自主通气量 5.26 比 2.22L）和心率变异性（高频 0.94 比 0.19ms，低频/高频-0.28 比-0.08，唾液皮质醇-0.13 比-0.04μg/dL）均优于常氧训练组。
与常氧训练相比，缺氧训练是肥胖老年人群健康促进的一种新颖而成功的方法。
