Effect of Aerobic Training on Adiponectin and Resistin Serum and Anthropometric Factors in Obese Women

Adiponectin and resistin are very important inflammatory factors in cardiovascular diseases. The objective of this study was to investigate the effect of a course of aerobic training on adiponectin, resistin serum, and anthropometric factors in obese women. Twenty-eight obese female volunteered and were randomly divided into experimental (14 subjects with means of age 37.1 ± 4.9 years, weight 82 ± 10.2 kg, and BMI 34.2 ± 4.3 kg/m2) and control (14 subjects with means of age 37.5 ± 5.3 years, weight 79.9 ± 9.5 kg, and BMI 34 ± 3.9 kg/m2) groups. Aerobic training protocol consisted of 4 sessions per week for 9 weeks. Each training session was a slow running trial at intensity of 65 to 75 percent of maximal heart rate for a period of 15 minutes. To follow the principle of overload, half-a-minute was added to each session after the second week, so that, at the last session the running time reached to 31 minutes. Before and after the training period, blood samples were taken. Data were analyzed using independent T-Test and ANCOVA. Food-regimen questionnaire was analyzed using “Food PROCESSOR 2”. Significance level of tests was considered P<0.05. Results showed that there is no significant difference in serum levels of adiponectin and resistin between control and experimental groups (P>0.05). However, aerobic training significantly reduced body mass index, body weight, waist to hip ratio, and body fat percent, and significantly increased the lean body weight and maximum oxygen uptake(P<0.05). It can be said that 9 weeks of aerobic training has no significant effect on serum levels of adiponectin and resistin in the obese women. But, it may cause improvements in anthropometric factors of the subjects. However, to achieve more conclusive results, further investigation is warranted.
