Background: It has been shown that physical activity increases bone mass. The aim of this study was to examine the effect of aerobic exercise on the levels of parathormone (PTH), alkalin phosphatase (ALP), and calcium (Ca) in untrained obese men.

Materials and methods: Totally, 22 untrained obese men (33.9±3.6 years old; body mass index: 32.65±3.42 kg/m2) volunteered to participate in our study. They were randomly divided into two experimental (n=12) and control (n=10) groups. The experimental group performed a training program for 12 weeks (three sessions per week and each session lasted 80 minutes with the intensity of 60-80% maximum heart rate). The control group didn’t participate in any intervention program. For measuring biochemical factors (ALP. Ca and PTH), blood samples were taken from each group. . Finally, t-test was used for the comparison of intergroup mean changes.

Results: The study findings showed that there was a significant increase in PTH and ALP in the experimental group compared to the control group (p<0.001). However, no significant difference was seen in the concentration of Ca in the experimental group. Furthermore, there was a significant decrease in the fat percentage, body mass index, and weight in the experimental group (p<0.001).

Conclusion: Results showed that a three-month aerobic exercise with the intensity of 60-80% of maximum heart rate causes a significant change in markers of bone metabolism in the obese men. These changes can indicate an increase in calcium absorption and may be the effects of anabolic of PTH and exercise.
