The Effects of Eight Weeks Upper Body and Lower Body Resistance Training on Plasma Adiponectin and Leptin Levels in Young Men

Background. Adipose tissue secrets various hormones in body such as adiponectin which has close relationship with controlling weight. Objectives. Therefore, the present article determines movement pattern effect of resistance training on adiponectin, in young men. Methods. 40 male untrained students in 23.8&plusmn;2.66 years old and weight of 67.43&plusmn;4.96 kg were randomly selected, who participated volunteering in this investigation, from upper body exercise, lower body exercise , combined (three resistance exercise sessions were held in each week during 8 weeks, 5 exercise sets with 60-85% of one repetition maximum) and control exercise (n=10). Blood samples were measured completely similarly in three steps of pre-test, fourth week, and one day after the eighth week exercise analyzed. Results. It is showed that in upper body group after the 8th week, adipose percentage reduced 7.39% (P<0.002) and leptin was decreased up to 64.02% (P<0.001), adiponectin significantly increased 90.42% (P<0.001) than pre-test step. In addition, in lower body group, adipose percentage reduced 7.39% (P<0.006) and leptin decreased 56.95% (P<0.001), adiponectin significantly increased 87.82% (P<0.012), than pre-test step. In combined group, body mass index (BMI) increased 1.88% (P<0.006), muscular mass increased 2.24% (P<0.007), and adiponectin significantly increased 91.56% (P<0.001), leptin (P<0.001) (59.3%) after eight weeks training significantly decreased than pre-test step. Conclusion. Various resistance exercises, increase adiponectin and leptin that are associated with change body composition. These changes can be effective for prevention of cardiovascular diseases.
