Each of the group was re-divided into exercise-training group and non-exercise-training group. The values of BMD were detected by the Hologic Sahara Clinical Bone Sonometer, the jump performances were measured by the Rebound Jumping Device. results: The values of BMD show a increasing tendency during adolescence. And there are significant differences of the values of BMD between 10-15years group and 16-20 years group;The values of BMD in training groups were significant difference with the values of BMD in non- training groups,which showed exercise-training can increase the values of BMD;The index reflecting the jump power of the inferior limb has a significant correlation with the values of BMD,and sport training can affect this correlation. |
