: The present study examined the agreement and associations of the 5-time sit-to-stand (5STS) test, the countermovement jump test, and lower-limb muscle power equations with a set of physical performance tests in older adults. Five hundred and thirty-four community-dwelling older adults were recruited for the study. Lower-limb muscle power measures included 5STS, the countermovement jump test, and muscle power equations. Isometric handgrip strength, timed "up-and-go!", the 6 min walking test, one-leg stand, and walking speed at usual and fast paces were used to assess physical performance. Pearson's correlations and Bland-Altman analyses were conducted to examine associations among muscle power measures. Linear and multiple regressions were run to explore associations of 5STS, the countermovement jump test, and muscle power equations with physical performance tests. Weak correlations were observed among lower-limb muscle power measures. Bland-Altman results indicated important differences among the countermovement jump test, 5STS, and muscle power equations. Results of multiple linear regressions indicated that 5STS, the countermovement jump test, and muscle power equations were significantly associated with measures of muscle strength and mobility. However, only 5STS was significantly associated with balance. Our results indicate that the performance on the countermovement jump test and 5STS is weakly correlated with lower-limb muscle power equations. The only exception was the correlation found between the countermovement jump test and relative muscle power, highlighting the importance of accounting for body mass in muscle power evaluations. Muscle power measures were similarly associated with performance on handgrip strength, timed "up-and-go!", and the 6 min walking test. The exclusive association of 5STS with balance suggests that a reassessment of 5STS muscle power equations may be warranted.
本研究检验了5次坐立试验（5STS）、反向运动跳跃试验以及下肢肌肉力量方程与一组老年人身体机能测试之间的一致性和关联性。招募了534名居住在社区的老年人参与该研究。下肢肌肉力量测量包括5STS、反向运动跳跃试验以及肌肉力量方程。采用等长握力、定时起立行走试验、6分钟步行试验、单腿站立以及正常步速和快速步速下的步行速度来评估身体机能。进行Pearson相关性分析和Bland-Altman分析以检验肌肉力量测量之间的关联性。进行线性回归和多元回归以探究5STS、反向运动跳跃试验以及肌肉力量方程与身体机能测试之间的关联性。下肢肌肉力量测量之间观察到弱相关性。Bland-Altman分析结果表明反向运动跳跃试验、5STS和肌肉力量方程之间存在显著差异。多元线性回归结果表明，5STS、反向运动跳跃试验和肌肉力量方程与肌肉力量和活动能力测量显著相关。然而，只有5STS与平衡显著相关。我们的结果表明，反向运动跳跃试验和5STS的表现与下肢肌肉力量方程弱相关。唯一的例外是反向运动跳跃试验与相对肌肉力量之间的相关性，这突出了在肌肉力量评估中考虑体重的重要性。肌肉力量测量与握力、定时起立行走试验和6分钟步行试验的表现同样相关。5STS与平衡的独特关联表明可能有必要重新评估5STS肌肉力量方程。
