The Effect of a Three-Month Intensive Intermittent Training on Plasma Chemerin and some Factors Related to Body Composition on Overweight Males

Chemerin is a new adipocytokine which has recently been discovered and has an important role in the metabolic syndrome. It plays a role in the regulation of adiposite and glucose metabolism of liver and skeletal muscle. In the present study the effect of a three-month intensive intermittent training on plasma chemerin and some factors related to body composition on overweight males was investigated. The present Quasi-experimental designed study used pre-test post-test for control and experimental groups. Twenty students of Kashan University of Medical Sciences with BMIs between 25 and 30 kg / m2, were purposefully selected and randomly and equally put in the experimental group with mean of (age: 22.40±4.49, weight: 93.60±4.64, height: 177±4.49) and in the control group with mean of (age: 22.60±1.42, weight: 93.20±3.15, height: 176.30±3.94). Experimental group practiced in a high-intensity interval training program for 12 weeks, 3 sessions per week with an intensity of 90% maximum heart rate. Before and after exercise, plasma chemerin levels, weight, body fat percentage, body mass index and waist-hip ratio (WHR) were calculated. Kolmogorov-Smirnov test was used for the normalization of the data. For within-group and between-group differences t-test (dependent and independent, respectively) was run (P≤ 0.05). Results showed that three-month of high-intensity interval training of running had a significant effect on decreasing the plasma chemerin levels, body weight, body fat percentage, BMI (P=0/0001), and WHR (P=0/012) in the experimental group compared to control group. Significant differences were observed for within group (P≤0/05). It seemed that three-month of high-intensity interval training as a non-invasive and non-pharmaceutical way could have a positive effect on reducing the levels of chemerin and some anthropometric indicators associated with obesity and overweight.
