摘要

通过结合基于肌电图（EMG）的振幅和频率参数、快慢抽动肌纤维比率、线性化时间累积效应的时间乘数和标准化所考虑的肌肉数量的综合效应的肌肉乘数，我们开发了一个多肌肉疲劳模型（MMFM）。我们通过研究10名男性受试者使用0.91 kg和2.72 kg哑铃执行一个持续到筋疲力尽的静态任务和两个重复的动态任务（低和高任务难度水平）的疲劳发展模式来验证该模型。结果表明MMFM对疲劳相关的神经肌肉变化敏感，能准确预测肩关节疲劳。

An electromyography-based multi-muscle fatigue model to investigate operational task performance.

We developed a multi-muscle fatigue model (MMFM) by incorporating electromyography (EMG)-based amplitude and frequency parameters, the fast-to-slow twitch muscle fiber ratio, a time multiplier to linearize the cumulative effect of time, and a muscle multiplier to standardize the combined effect of the number of muscles being considered. We validated the model by investigating fatigue development patterns of 10 male subjects performing one sustained-till-exhaustion static and two repetitive dynamic tasks (low and high task difficulty levels) using 0.91 kg and 2.72 kg dumbbells. The results indicated that the MMFM was sensitive to fatigue-related neuromuscular changes and predicted shoulder joint fatigue accurately.
