Summary:Namboonlue C, Yuyongsin S, Wanna S, Muangritdech N. The Effects of Five Weeks Low-Intensity Aerobic Training Under Hypoxia on Body Composition and Oxygen Consumption in Overweight/Obesity Men. JEPonline 2021;24(4):33-44. The purpose of this study was to examine and compare the effects of low-intensity aerobic training under moderate hypoxia on body composition, muscle strength-endurance and maximum oxygen uptake of overweight or obese males. Twenty healthy overweight or obese males, aged 19 to 24 years, from Ubon Ratchathani Rajabhat University were randomly divided into 2 Groups: (a) Control Group (Normoxia; NORM, [F.sub.I][O.sub.2] = 20.9%); and the (b) Experimental Group (Hypoxia; HYP, [F.sub.I][O.sub.2] = 15.8%). Both Groups performed low-intensity aerobic training for 30 min*[d.sup.-1], 3 d*w[k.sup.-1] over a 5-week period at 60% heart rate reserve, while the subjects in the NORM performed exercise under normoxic condition. All variables were measured before and after the 5-weeks of the experimental period. The number of repetitions in the knee flexion and maximum oxygen uptake were significantly increase in the HYP (31.0 [+ or -] 18.4% and 18.9 [+ or -] 14.7%, mean [+ or -] SD) compared with the NORM (17.5 [+ or -] 13.0% and 6.8 [+ or -] 4.7) Similarly, HYP showed a substantial decrease in body weight, body mass index, body fat, and visceral adipose tissue (-2.3 [+ or -] 2.8%, -2.6 [+ or -] 3.0%, -7.9 [+ or -] 10.5%, and -12.0 [+ or -] 15.0%, respectively) when compared to their baseline with no significant difference between the 2 Groups. Low-intensity aerobic training under hypoxia could be used as an alternative and novel therapeutic strategy to improve body composition and oxygen consumption in overweight or obese subjects.
