研究概览
简要总结
This study examines how different standing postures and whole-body vibration conditions affect spinal reflex activity. Participants will stand in various positions-with and without vibration of two amplitudes-and H-reflex responses from the soleus muscle will be recorded. Additionally, vibration-induced reflex latency will be assessed across multiple vibration frequencies.
详细描述
Participants will engage in a structured set of experimental tasks designed to evaluate the effects of postural mechanical loading, and whole-body vibration.
The protocol includes four primary standing conditions:
Quiet bipedal stance,
Single-leg stance on the left side,
Bipedal stance during whole-body vibration (WBV), and
