The purpose of the study was to analyze the test-retest reliability of an isometric and isometric/vibratory muscular strength protocol in the bilateral seated bench press (BSBP), bilateral seated rowing (BSR), unilateral seated right knee extension (USKER), and left knee extension (USKEL) tests controlled using functional electromechanical dynamometry (FEMD) in healthy young adults. A repeated measures design was used to determine the reliability of a muscular strength protocol in isometric and isometric vibration modes with FEMD. No significant differences were found in test-retest analysis ( > 0.05; ES < 0.20); and high reliability (CV = 4.65-5.02%; ICC = 0.99-0.98) was found for BSBP measures, and acceptable reliability (CV = 3.71-9.61%; ICC = 0.98-0.95) was found for BSR, USKER, and USKEL. Furthermore, the coefficients between the two measures were strong (r = 0.963-0.839) and highly significant ( = 0.001) for maximal strength in the isometric and maximal isometric/vibratory assessment of muscle strength in all muscle strength tests. This study demonstrates that isometric and maximal isometric/vibratory strength in the BSBP, BSR, USKER, and USKEL tests can be measured with high reliability and reproducibility using the FEMD.
本研究的目的是分析在健康年轻成年人中，使用功能机电测力计（FEMD）控制的双侧坐姿卧推（BSBP）、双侧坐姿划船（BSR）、单侧坐姿右膝伸展（USKER）和左膝伸展（USKEL）测试中，等长和等长/振动肌肉力量方案的重测信度。采用重复测量设计来确定FEMD在等长和等长振动模式下肌肉力量方案的信度。重测分析未发现显著差异（>0.05；效应量<0.20）；BSBP测量结果具有高信度（CV = 4.65 - 5.02%；ICC = 0.99 - 0.98），BSR、USKER和USKEL具有可接受的信度（CV = 3.71 - 9.61%；ICC = 0.98 - 0.95）。此外，在所有肌肉力量测试的等长最大力量和最大等长/振动肌肉力量评估中，两种测量之间的系数很强（r = 0.963 - 0.839）且高度显著（= 0.001）。本研究表明，使用FEMD可以高度可靠且可重复地测量BSBP、BSR、USKER和USKEL测试中的等长和最大等长/振动力量。
