The Effects of Combined Exercise on Body Compositions and Blood Lipid Profiles in Korean Obese Women

Abstract

The purpose of this study was to investigate the effects of a combined exercise including weight training, ashtanga yoga, jazzercise on the body compositions and blood lipid profiles in Korean obese women. Twenty obese women (more than 30% of body fat (BF)) were allocated combined exercise (CE, n=10) and single exercise (SE; jazzercise only, n=10) groups. They took exercise for 90 minutes a day, 3 times a week during 12 weeks. The body compositions and blood lipid profiles measured before and after exercise. Collected data were analyzed with SPSS program (version 12.0) by using paired and independent t‐tests and Pearson's correlation. After 12 weeks exercise, CE presented decreased weight, BMI, % BF, and increased muscle mass (MM). SE also presented decreased weight, BMI, and % BF but there was no change in MM. Compared to SE, CE had higher MM change after exercise (P<0.01). CE and SE presented decreased TC and TG; however only CE had HDL increase after exercise. Compared to SE, CE presented higher TG reduction (P<0.01) and HDL increase (P<0.001) after exercise. In both groups, there was negative correlation between changes of MM and TG (P<0.01); whereas, fat mass and % BF changes were positively correlated with TG change (P<0.05). In conclusion, CE can improve body compositions and blood lipid profiles than SE in Korean obese women. In addition, body composition changes after exercise may ameliorate blood lipid profiles.
