Sarcopenia is among the most deleterious effects of aging. The objective of this study was to analyze the relationship between performance tests and muscular volume over the life span of male and female participants. A correlation study was conducted with healthy individuals (50 males and 47 females) between the ages of 20 and 94; the study group included active older people, sedentary younger people, and young athletes. Muscular volume was determined by tomography and muscular performance (4-meter speed tests [4 MSTs], chair test, and handgrip test), and a correlation analysis between the groups was performed. Sex-related differences were observed between the variables; in males, muscle volume and functional parameters were closely related with age and physical activity, whereas in females, they were not related at all. Male and female muscle volume and performance demonstrate strong differences, which should be considered during clinical evaluations of sarcopenia.
肌肉减少症是衰老最有害的影响之一。本研究的目的是分析男性和女性参与者在整个生命周期中性能测试与肌肉体积之间的关系。对20至94岁的健康个体（50名男性和47名女性）进行了一项相关性研究；研究组包括活跃的老年人、久坐不动的年轻人和年轻运动员。通过断层扫描确定肌肉体积，并进行肌肉性能测试（4米速度测试[4 MSTs]、椅子测试和握力测试），并对各组之间进行相关性分析。在变量之间观察到了性别相关差异；在男性中，肌肉体积和功能参数与年龄和身体活动密切相关，而在女性中，它们完全不相关。男性和女性的肌肉体积和性能表现出强烈差异，在肌肉减少症的临床评估中应予以考虑。
