摘　　要：采用文献法资料法和实验法调查119名中等职业学校学生（以下简称中职生）（16～18岁）的骨密度（bone mineral density，BMD）和参加运动的情况。结果显示男性运动组与不运动组BMD值有显著差异性。女性中职生运动组有使骨密度增加的趋势。运动时间长、运动频率高的组别BMD也高。男性每日运动时间大于1h组与小于1h组的BMD值具有显著性差异。结论：运动对BMD有积极影响，运动频率大于3次／周及每日运动时间超过1h对BMD的影响最为明显。Objective： To understand the movement factor on bone mineral density in the impact of the post of Health, Physical Education workers to provide a reference and basis for intervention. Methods： The survey of 119 secondary schools in a grade of Health 116 - 18 years） bone mineral density （bone mineral density, BMD）, and participate in the case of movement. Results： The male exercise group and non - exercise group BMD values significantly different. The female exercise group movement so that the trend of increase in bone mineral density. Movement time, movement of groups of high frequency high BMD. Daily movement of men is greater than 1 hour time of less than 1 hour group and the BMD value of group with significant difference. Conclusion： The campaign has had a positive impact on BMD, frequency greater than 3 times in a week and a daily exercise time more than 1 hours of the most obvious impact of BMD.
