About this trial
This cross-sectional, comparative study aims to evaluate and compare the surface electromyographic (sEMG) activity of the gastrocnemius (medial and lateral) and soleus muscles during static and dynamic contraction tasks. Participants will perform three tests-resting state, isometric, concentric, and eccentric contraction, and dynamic gait-with bilateral measurements. A subgroup analysis will examine muscle activity variations based on foot posture, using the Foot Posture Index (FPI). The study uses the validated mDurance® sEMG system to obtain objective data under controlled lab conditions. The findings will enhance understanding of the functional role of each muscle and could inform rehabilitation and injury prevention strategies.
