Abstract:
Purpose: Serum Alkalin phosphatase (ALP) is an osteoblastic protein whose levels may be affected by exercise. Research has shown that exercise may increase bone density through increasing the level of bone constitute markers such as calcium, phosphor, and ALP. The aim of the present research was to compare the markers of the bone metabolism (calcium, phosphor, and ALP) between 20-35 year-old female basketball players and non-athletes in Golestan province.
Material and Methods: 12 female, professional basketball players and 15 non-athletes participated in this study as the experimental group and the control group respectively. To study the intended markers, 5 cc of blood was collected from the archival vein of the participants in a sitting position. To analyze the data, shapiro wilk, mann whitney u and independent T-test were used. SPSS software version 18 was used to analyze the data. The significance level was set at p<0.05.
Results: Data showed a significant increase in the ALP level of the experimental group (p=0.001) but no significant difference was observed in the calcium (p=0.792) and phosphor (p= 0.905) levels between the two groups. Discussion and Conclusions: According to the results, different intensities of exercise may improve and maintain the level of bone osteoblastic proteins and bone formation stimulating factors such as ALP.

As exact mechanisms of interaction between physical activity and bone metabolic markers are still unknown on one hand, and on the other, not enough attention has been paid to studying bone metabolic markers in young women before menopause, the present research aims at comparing the effects of weight bearing exercises on calcium, phosphor, and serum APL levels in 20 to 35- year old, female, basketball players and non-athletes in Golstan province.
The results of the present study indicated that exercise training in the experimental group positively correlates with the ALP serum levels and may increase bone calcification, bone formation or mineralization (mechanical stress theory).
Kemmler et al ( 2007) studied the effects of long-term exercise, stretching, and intense aerobic exercise on the BMD of pelvic and cervical vertebrae of 40 women and observed an increase in the BMD and a decrease in the rate of bone density loss, in the experimental group as compared to the control group [35]."
