Effects of Resistance Exercise on Adipokines According to Menstrual Cycle in Obese College Women

Abstract

PURPOSE The purpose of this study was to investigate the level of lipids and adipokines according to the menstrual cycle (follicular and luteal phase) and to investigate the effect of resistance exercise on the change of lipids and adipokines according to menstrual cycle. METHODS The subjects were living in C city and body fat of over 30% in the obesity college women students (n=30). These were divided into the follicular phase group (n=15) and the luteal phase group (n=15) by random sampling. All the contents of the study were approved by Kangwon National University IRB and applied to the guidelines for personal safety. RESULTS There was no interaction effect between group and time on body composition, lipid profiles and adipokines. Body composition showed a significant decrease in body percent fat in both groups. After the exercise program, there was a significant difference between groups in body percent fat. Also, TC was significantly decreased after 16 weeks compared with 0 week. Leptin concentration was significantly higher in the luteal group than in the follicular group and was significantly decreased after 16 weeks of exercise program in the luteal group. Adiponectin concentration was also significantly higher in the luteal group than in the follicular group, but in the luteal group, there was a significantly increase after 16 weeks of exercise program compared 0 week. CONCLUSIONS This study suggests that the concentration of aidpokine in the luteal phase is higher than that of the follicular phase and that the timing of blood collection is very important for women. Resistance exercise seems to have an effect on adipokine concentration.
