The effect of 6-months aerobic exercises on Bone-specific alkaline phosphatase and parathyroid hormone in obese inactive woman

Empirical evidence reveals positive effects of physical activity on skeletal mass. Hormones and biochemical markers of bone measurements indicate that the intracellular metabolism can explain the relationship between physical activity and bone metabolism. The aim of this study was to evaluate the effects of six months of aerobic exercise training on bone-specific alkaline phosphatase and parathyroid hormone in obese women idle. This is an quasi-experimental study. Sample consisted of 15 middle-aged female employees who were targeted sampling method. samples randomly into two experimental groups (ten patients) and control group (five patients) were classified by body mass index greater than 30 kg per square meter، and accordingly the women were overweight. Aerobic exercise protocol consisted of six months (75 sessions)، each session lasting 60 minutes with an intensity of 65-55% heart rate reserve ((HRR was. To measure PTH-specific ELISA kit was used. well as calcium، phosphorus and alkaline phosphatase were measured by Atvanalayz. statistical operations were performed using SPSS 16 software and a significance level of P<0. 05 was considered. Results showed that aerobic training no significant difference on BMI and percent body fat in the control group. but in the experimental group were significantly decreased. Also، none of the parameters studied serum (alkaline phosphatase، Pratvrmvn، phosphorus، and calcium) showed no significant change. 6-month aerobic exercise training with the intensity of 55-65 percent of heart rate reserve does not significant change in the parathyroid hormone، phosphorus، calcium and bone-alkaline phosphatase in Inactive obese women.
