观察动态疲劳与等距疲劳收缩对后续强度性能的影响

Action observation (AO) and empathy engage neural networks involved in motor execution, suggesting that watching others perform actions might influence one’s own motor behavior. It remains unclear whether observing fatigue-inducing contractions, affects subsequent performance. Sixteen recreationally active participants completed maximal voluntary isometric contractions and dynamic tasks under both observation and no-observation conditions in a randomized, cross-over design. Key outcomes including quadriceps and hamstrings electromyography (EMG), maximal voluntary isometric contraction (MVIC) f
