从机械应力对骨组织代谢影响的假设出发，提出了肌力与骨矿含量（BMC）、骨矿密度（BMD）的关系。然而，在年轻男性中，直接的关系还没有很好地建立起来，因为力量的增强能够有效地改变骨骼健康，仍然需要进一步研究。本研究的目的是分析肌肉力量对大学生骨矿含量和骨密度的影响。36名男性（24.9 +/- 8.6 y/o）通过双能X线吸收测定法（DXA）评估局部和全身组成。一次重复最大测试（1 RM）进行了评估，在平板卧推（BP），lat-pull down（LPD），腿卷曲（LC），膝关节伸展（KE），腿按45度（LP 45）的演习。线性回归模型的BMD和BMC的区域身体组成和1 RM值的关系。对离散度和误差（R-adj（2）和估计标准误差（SEE））的测量进行了测试，设置。在
The relationship between muscle strength and bone mineral content (BMC) and bone mineral density (BMD) is supposed from the assumption of the mechanical stress influence on bone tissue metabolism. However, the direct relationship is not well established in younger men, since the enhancement of force able to produce effective changes in bone health, still needs to be further studied. This study aimed to analyze the influence of muscle strength on BMC and BMD in undergraduate students. Thirty six men (24.9 +/- 8.6 y/o) were evaluated for regional and whole-body composition by dual energy X-ray absorptiometry (DXA). One repetition maximum tests (1RM) were assessed on flat bench-press (BP), lat-pull down (LPD), leg-curl (LC), knee extension (KE), and leg-press 45 degrees (LP45) exercises. Linear regression modelled the relationships of BMD and BMC to the regional body composition and 1RM values. Measurements of dispersion and error (R-adj(2) and standard error of estimate (SEE)) were tested, setting. at
