Effects of Endurance and Resistance Training on Plasma Levels of Chemerin and Factors Related to Obesity in Overweight and Obese Females

Obesity is accompanied with a lot of metabolic disorders such as changing Adipokines like Chemerin. The present study evaluated the effects of endurance and resistance training on Plasma levels of chemerin and Factors related to obesity in overweight and obese females. In this study 34 overweight and obese females with an average of age (22.29±2.49 years), body mass index (BMI) (30.19±2.79 kg/m2), weight (77.23±10 kg) participated voluntarily and were randomly assigned into two experimental groups (n=12) and one control group (n=10). Endurance and resistance training groups trained for 8 weeks (4 days a week), respectively with intensity of 65 to 80% maximum heart rate (HRmax) and 65 to 80% one repetition maximum (1RM). In two steps of pre-test and post-test, after 12 hours of fasting, the blood samples were collected in the same conditions and ELIZA method was used to assess Plasma levels of Chemerin. Kolmogorov-Smirnove test was used to evaluate the normal distribution of data, the variation within groups using paired t-test and variation between groups analysis of variance (ANOVA) and LSD were used in significant level (P<0.05). Plasma Chemerin decreased significantly after 8 weeks of training in endurance group (P<0.05), but there was no significant change in resistance group (P>0.05). Also In the experimental groups, factors related to obesity (weight, fat mass, WHR and BMI) were significantly decreased while the maximum oxygen consumption were significantly increased (P<0.05). Both endurance and resistance training, improved Factors related to Obesity and maximum oxygen consumption, but endurance training with a significant reduction in plasma chemerin, has a more effective role in health and reducing inflammation in overweight and obese females.
