握力和伸膝力量经常被用来描述肢体的整体肌肉力量。我们试图确定这些措施是否实际上反映了一个共同的结构。对164名健康男性和女性(18-85岁)的等长握力和伸膝力量进行了双侧标准测量。使用皮尔逊相关(R)、克朗巴赫α、主成分分析和多元回归/相关分析来研究测量的维度。左右握力和膝关节伸展扭矩高度相关，内部一致，并加载在单个组件上。性别和年龄解释了这两项指标的差异，但身高增加了对握力的解释，而体重增加了对膝关节伸展力量的解释。在健康的成年人中，握力和伸膝力量反映了一种常见的潜在结构。然而，这些指标受到身高和体重的不同影响。
Both grip and knee extension strength are often used to characterize overall limb muscle strength. We sought to determine if the measures actually reflect a common construct. The isometric grip and knee extension strength of 164 healthy men and women (18–85 years) were measured bilaterally using standard procedures. Pearson correlations (r), Cronbach alpha, principal components analysis and multiple regression/correlation were used to investigate the dimensionality of the measures. Left and right grip forces and knee extension torques were highly correlated, internally consistent, and loaded on a single component. Gender and age explained the variance in both measures, but height added to the explanation of grip strength, whereas weight added to the explanation of knee extension strength. Among healthy adults, grip and knee extension strength reflect a common underlying construct. The measures, however, are affected differently by height and weight.
