摘要

Purposes: The purposes of this study were to investigate the effects of different types of sport trainings on bone mineral density (BMD) as well as on different factors of body composition and muscle strength. Methods: Fourteen highly trained athletes and six untrained people participated in this study. Subjects were volleyball players (V; n=7) swimmers (S; n=7) and control groups (C; n=6). First, all of the subjects went to hospital having their femoral (F), lumbar (L2-4; L) and radius (R) bone density measured by dual energy x-ray absportiometer (DEXA). Then seven days later, subjects went to the lab to be measured on their body compositions and muscle strength (including: knee, hip and shoulder) were also tested. One-way ANOVA and Tukey post-hoc were used to analyze the differences among these three groups. The α level was set at .05. Results: V and S teams had significant higher muscle mass (p＜.05) and bone mass (p＜.05) than C team. On (F) and (L) sits bone density, V and S teams were also significant higher than C team (p＜.05). On (R) sit bone density, only V team was significant higher than C team (p＜.05). During the muscle strength comparison, the great performance on V team and S team were significantly different to C team, except on shoulder flexion performance. Conclusion: According to this study, high impact exercise will help person increase BMD, and low impact exercise may as well. Doing exercise regularly can increase muscle mass, bone mass and muscle strength performance, also BMD increased may due to muscle strength performance.
