The present study aimed to explore the possibility of comprehensively assessing whole-body muscle strength by testing as few muscle groups as possible, using a single testing method (isometric or isokinetic dynamometry) and a single variable (maximal force or rate of force development). Knee, hip, shoulder and elbow extensors and flexors were evaluated in males with high (n = 26) and low strength levels (n = 32). The principal component analysis revealed three factors that explained 62.5% of the total variance, while the main factors were loaded by the different testing methods and strength variables for the muscles acting on the knee (first component), hip (second component) and arm joints (third component). These results were confirmed by a three-way ANOVA which revealed a significant factor of group (P < 0.001) and the interaction test type × group (P = 0.002), but not of test type (P = 0.644), muscle group (P = 0.999), or their interactions (P > 0.205). The correlations of strength outcomes across the muscles ranged from trivial to very large ( range = -0.17, 0.84), being generally higher for the antagonistic muscles. Overall, a comprehensive assessment of whole-body muscle strength can be obtained using isometric dynamometry and maximal force, but it should consider at least one muscle group from the antagonistic pair.
本研究旨在探讨通过使用单一测试方法（等长或等速测力法）和单一变量（最大力量或力量发展速率），尽可能少地测试肌肉群来全面评估全身肌肉力量的可能性。对高力量水平（n = 26）和低力量水平（n = 32）的男性进行了膝、髋、肩和肘伸肌及屈肌的评估。主成分分析揭示了三个因素，解释了总方差的62.5%，而主要因素由作用于膝关节（第一成分）、髋关节（第二成分）和手臂关节（第三成分）的肌肉的不同测试方法和力量变量所负荷。这些结果通过三因素方差分析得到证实，该分析揭示了显著的组因素（P < 0.001）以及测试类型×组的交互作用（P = 0.002），但未揭示测试类型（P = 0.644）、肌肉群（P = 0.999）或它们的交互作用（P > 0.205）。各肌肉力量结果之间的相关性范围从微不足道到非常大（范围 = -0.17, 0.84），拮抗肌之间的相关性通常更高。总体而言，使用等长测力法和最大力量可以获得对全身肌肉力量的全面评估，但应考虑拮抗肌对中的至少一组肌肉。
