Abstract
Materials and Methods : 44 non-athletic women in their thirties (27.18±3.65) were studied randomly in four groups: 1) Exercise, 2) Calcium and vitamin D supplement, 3) Exercise and supplement, and 4) control. The subjects exercised three sessions a week for 9 weeks, each session lasted 30-45 minutes. The blood and urinary samples were collected from the experimental and control groups while they fasted either before or after exercise program. The concentration of alkaline phosphates and procollagen I, C terminal (PICP) had been measured using DGKC and HPLC techniques, respectively. The collected data had been combined with the statistical t-tests and were analyzed by ANCOVA (p<0.05).
Results : Significant increasing of ALP and PICP was observed in exercise group (p=0.001) and exercise + supplement group (p=0.001). In supplement group, alkaline phosphate and procollagen type 1, C-terminal show a significant decrease (p=0.001), while the difference was not significant in the control group.
Conclusion : Generally, the research results show that the intensive aerobic exercise and adequate intake of calcium and vitamin D affect positively the bone mass development during youth and they reduce fracture risk however, such claim needs further investigations.
