摘要：

背景：超声检测骨强度是骨骼状态的一项重要指标。
目的：探讨舞蹈学员骨强度特点及其影响因素。
方法：纳入专业舞蹈学习8年以上受试者60人，采用超声骨密度仪对其进行身体成分和左脚脚踝骨强度测试。
结果与结论：舞蹈专业受试者骨强度值显著高于同龄人平均水平。无论男、女受试者骨强度值均具有随着体质量指数增长而增长的趋势，女受试者骨强度具有与脂肪量成正比，与左腿推定肌肉量成反比的趋势。提示体质量指数可能是决定骨强度的重要因素，运动影响骨强度可能存在阈值，阈值下运动能提高骨强度，超过阈值则无益。

Abstract:

BACKGROUND: Bone strength as one of national physical examination items is an important health index.
OBJECTIVE: To investigate the dancer’s bone strength features and the influential factors.
METHODS: A total of 60 dance professional subjects were included and bone mineral density was measured through the use of ultrasound bone mineral density apparatus.
RESULTS AND CONCLUSION: Bone mineral density was significantly greater in the dance professional subjects than in age cohorts. The bone mineral density of male and female dance professional subjects was significantly increased with increasing body mass index. The bone mineral density of female dance professional subjects was positively proportional to fat amount and negatively proportional to the amount of presumption trend of left leg muscle. Results showed that body mass index may be an important factor determining bone mineral density. There may be a threshold for exercise influencing bone strength, and under the threshold, exercise can increase bone mineral density and excessive threshold is of no use for increasing bone mineral density.
