Relation between Osteocalcin and Metabolic Profils in Overweight Men: Comparison of Aerobic and Resistance Trainings
Objectives: Recent studies have shown that exercise by affecting bones causes the release of hormones that are effective in
regulating blood glucose, lipid profile and preventing vascular calcification. The present study aims to Comparison effect
of aerobic and resistance exercises on Osteocalcin and Metabolic Profils in Overweight men.
Methods: total of 33 overweight healthy men (BMI 29 = 67.96 ± 0.96 and age 33.2 ± 2.23) were randomly assigned into
three groups: control (n = 11), aerobic (n = 11) and resistance exercise (n = 11) groups. The training program was conducted for 8 weeks, 3 sessions per week for the training groups. Body compositions parameters (weight, body fat percent,
BMI) were analyzed, osteocalcin and blood biochemical parameters were assessed from fasting blood samples before and
after 8-week exercise programme.
Results: Body fat, BMI and body weight reduction following exercise (P<0/05), significantly increased serum Osteocalcin
(P<0/05, baseline vs Post exercise) and blood biochemical parameters significantly changes (P < 0/05). Increase in osteocalcin had a negative correlation with changes in body composition, as well as HOMA-IR and HDL, LDL not significantly
(all P > 0/05).
Conclusion: Aerobic and Resistance exercise cause to changes in body weight, body fat, BMI, as well as the increase level of
osteocalcin and improvement of glucose metabolism and lipid profiles. However, the difference between the two training
groups was not statistically significant.
