| 摘 要： | 探讨青春发育期男性青少年在生长发育过程中骨密度(bone mineral density，BMD)值与下肢跳跃能力的关系及运动训练对其影响。对10～20岁男性青少年63名，依据年龄分为10～15岁和16～20岁组；依据是否从事规律的运动训练，再分为运动员组和非运动员组。超声法测量跟骨BMD，下肢跳跃能力指标使用日产Rebound Jumping测跳仪测量。结果：男性青少年的BMD在整个青春期呈上升趋势，且10～15岁和16～20岁组BMD有显著性差异；运动组和非运动组的BMD也呈显著性差异，提示早期运动训练可以改变骨密度；男性青少年的BMD与反映下肢跳跃能力的指标具有明显相关性，且此相关度受运动训练的影响，运动训练具有正向促进作用。 |

| Abstract: | To know the relationship between bone mineral density and jump power of the inferior limb in male teenagers and the effect of sport training on it,63 Shanghai schoolboys aged 10-20 years were measured, and they were divided into 10-15 years group (including 26 subjects ) and 16-20 years group (including 37 subjects). 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. |
| Keywords: | male adolescent bone mineral density jump power of the inferior limb sport training |
