Jeong, Ⅰ.G., Yoon, J.H., Lee, H.H. The Effects of Blood Somatomedin-C, Calcitonin and Osteocalcin Level on Weight Lift Athletes' BMD. Exercise Science, 11(2): 431-440, 2002. The purpose of this study was to investigate the relationship between bone mineral density(BMD) and Insulin-like growth factor-1(IGF-1), Osteocalcin and Calcitonin in adolescent weight lifter and non-athletes. The subjects in this study were 10 adolescent weight lifters and 10 age-matched non athletes. In all subjects, BMD in lumbar spine was measured using dual-energy x-ray absorptiometry and to investigate the possible hormonal relationships underlying the effects on BMD, serum concentrations of IGF-1, Osteocalcin and Calcitonin were measured. As a results, there were significant difference in mean BMD and resting IGF-1 level between two groups. But there was no significant difference in the level of Osteocalcin and Calcitonin between two groups. We also found the significant correlation between BMD and IGF-1 but not among the other variables.These findings suggest that resistance exercise training might increase the regional bone mineral density, which would be affected by the higher IGF-1 level found in weight lifters.
