Abstract
Abstract Purpose The purpose of this study was to investigate the effects of high-intensity interval training (HIIT) on body composition, pulmonary function, and respiratory muscles strength in sedentary adults with obesity. Methods Thirty-one physically inactive adults with obesity (male and female), aged between 1 8 - 4 5 years, were recruited from Chulalongkorn University and were randomized into 2 groups: high-intensity interval training group (n=15) and control group (n=16). The experimental group performed a high-intensity interval training (HIIT), 3 days a week for a period of 12-weeks, while the control group remained their normal activities of daily living. Physical characteristics, body compositions, pulmonary functions, and respiratory muscle strength were measured before and after 12 weeks of training. Data were analyzed using paired t-test and independent ttest with a level of statistical significant at p<.05. Results Following a 12-week training, the HIIT group displayed significant improvements in body weight, body mass index, resting heart rate, systolic and diastolic pressures, %body fat, lean body mass, maximum oxygen uptake (VO2max), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), peak expiratory flow rate (PEF), maximum voluntary ventilation (MVV), maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) compared to prior training (all p<.05). In addition, the HIIT showed better improvements in body weight, resting heart rate, % body fat, VO2max, PEF, MIP, and MEP compared to the control (all p<.05). Conclusion A 12-week of HIIT is effective in improving in body composition, pulmonary function, and respiratory muscles strength in sedentary adults with obesity.
