Effects of 5-week Combined Exercise on Blood Lipid and Health-related Quality of Life in Obese Military Recruits

Abstract

PURPOSE This study was to investigate the effects of 5 weeks combined exercise on blood lipid profile and health-related quality of life in obese military recruits. METHODS Twenty-eight obese recruits were randomly assigned for exercise (n=14) and control (n=14) group. All groups performed a basic military training for 5 weeks. Additionally, exercise group conducted combined exercise consisting of twice a day, in the morning and afternoon, 3 days per week for 5 weeks. RESULTS The results of this study was following; The body weight and BMI were significantly decreased in all groups, in which rate of change showed higher in exercise group than control group (p<.001). In all groups, total cholesterol, triglycerides and LDL-C were significantly decreased compared to baseline (p<.001) whereas only HDL-C was significantly increased in exercise group (p<.01). In the 7 items of the health-related quality of life, there was no significant difference between groups while all groups showed significant improvements compared to baseline (p<.01). CONCLUSIONS These results showed that a 5 weeks combined exercise program during basic military training has positive effects on body composition, lipid profile and health-related quality of life in obese recruits.
