Background & aim: Decreased bone density, especially in women, is a health risk factor; therefore, the aim of the present study was to investigate the effect of a resistance training course with vitamin D supplementation on bone absorption markers in girls. Methods: The participants of the present semi experimental study were 24 non-athlete girls in Boroujerd (mean age 21.6 ± 2.04 years, mean height 155 ± 5.5 cm and average weight 64.13 64 4.9 kg) who participated voluntarily and were randomly divided into four groups of six (resistance training, vitamin D intake, resistance training with vitamin D intake and control group). Resistance training consisting of eight weeks (three one-hour sessions per week) was performed in accordance with the principle of overload. The participants were given Vitamin D supplementation for eight weeks (once a week) using vitamin D tablets (8 pearl IU50000) with 300 ml of water. Blood samples were taken 48 hours before the beginning of the protocol and 48 hours after the end of the last session to measure the serum concentrations of parathyroid hormone and calcitonin. ANCOVA and Bonferroni post hoc test were used to analyze the hypotheses. Results: The results indicated that after eight weeks of resistance training, as well as eight weeks of resistance training with vitamin D, a significant increase in serum calcitonin concentration (p=0.001) and a decrease in serum parathyroid hormone concentration (p=0.001) Occurred. Conclusion: It seems that resistance activity and vitamin D consumption increases calcitonin and decreases Parathormone in sedentary girls, which probably has a positive effect on bone mass.
