(1) Background: Regardless of the level of physical activity, performance monitoring is a valuable component of the training process. The aim of this research was to assess the reliability and sensitivity of parameter measurements using the Enode/Vmaxpro sensor. (2) Methods: Metric characteristics were examined for average velocity, peak velocity, average power, peak power, movement length, and movement duration. Twenty-seven participants (15 men and 12 women) underwent body composition analysis and testing on a combined leg extension/leg curl machine, performing the exercises with each leg individually under a 30% body mass load. Descriptive statistics, reliability analyses, and difference analyses were conducted to evaluate repeatability and sensitivity levels. The significance threshold was set at the level 0.05. (3) Results: Reliability parameters were found to be statistically significant, both overall (ICC: 0.937-0.991) and separately for men (ICC: 0.899-0.984) and women (ICC: 0.908-0.990). Sensitivity was confirmed through significant differences based on sex ( = 0.000), activity level ( = 0.000), and movement type ( = 0.000). No statistically significant differences were observed between right and left leg performance. (4) Conclusions: The findings suggest that the Enode/Vmaxpro sensor demonstrates sufficient sensitivity and reliability for muscle power testing in biomechanics and sports diagnostics.
(1) 背景：无论身体活动水平如何，运动表现监测都是训练过程中的一个重要组成部分。本研究的目的是评估使用Enode/Vmaxpro传感器进行参数测量的可靠性和敏感性。(2) 方法：对平均速度、峰值速度、平均功率、峰值功率、运动长度和运动持续时间等指标特征进行了检测。27名参与者（15名男性和12名女性）接受了身体成分分析，并在腿部伸展/腿部卷曲联合训练机上进行测试，每条腿在30%体重负荷下单独进行练习。进行了描述性统计、可靠性分析和差异分析，以评估重复性和敏感性水平。显著性阈值设定为0.05。(3) 结果：发现可靠性参数在总体上（组内相关系数：0.937 - 0.991）以及男性（组内相关系数：0.899 - 0.984）和女性（组内相关系数：0.908 - 0.990）中均具有统计学意义。通过基于性别（P = 0.000）、活动水平（P = 0.000）和运动类型（P = 0.000）的显著差异证实了敏感性。左右腿表现之间未观察到统计学上的显著差异。(4) 结论：研究结果表明，Enode/Vmaxpro传感器在生物力学和运动诊断中对肌肉力量测试具有足够的敏感性和可靠性。
