Effects of Aerobic and Resistance Exercises on Anthropometric Indices and Osteocalcin, Leptin, Adiponectin Levels in Overweight Men. (English)

Background and Aim: Physical activity causes the releases of bone resorption indices in the bloodstream by the mechanical load on bone, which in interaction with adipokines reduces obesity and prevent its complications. So, the present study aims to compare the effects of aerobic and resistance exercise on Anthropometric Indices and osteocalcin, leptin, adiponectin levels in overweight men. Materials and Methods: A total of 40 overweight young healthy men (BMI 28.67±0.96 and age 31.50 ± 2.23) were randomly assigned to control (n = 14), aerobic exercise (n = 13) and resistance exercise (n = 13) groups. Subjects in the exercise group were on 8-week supervised exercise training programme for three sessions per week (aerobic exercise were performed at 60-85% of HRR, and resistance exercise were performed at 55-75% of 1RM). Osteocalcin and adipocytokines (leptin, adiponectin) were assessed from fasting blood samples before and after the 8-week exercise programme. Data were analyzed by t-test and ANOVA. Ethical Considerations: This study with research ethics code IR.IAU.RASHT.REC.1396.124 has been approved by research ethics committee at Islamic Azad University, Rasht branch, Iran and also has been registered with code IRCT20180226038876N1 at Iranian Registry of Clinical Trials (IRCT). Findings: Aerobic and resistance training led to decrease in anthropometric indices (p0.05). Conclusion: Considering to the effects of aerobic and resistance exercise on osteocalcin and adipocytokines level, it seems that both exercise methods can be increasing mechanical load on bone mass and cause to change in energy metabolism and body weight and can be an important factor in decrease of obesity complications.
