Effects of Gastrocnemius Fatigue on Muscle Elasticity and Jumping

This study investigates the acute and 24-hour recovery effects of localized muscle fatigue on the viscoelastic properties of the medial gastrocnemius (MG) muscle and vertical jump performance. The research aims to quantify the changes in muscle stiffness, tone, and elasticity immediately after a standardized fatigue protocol and to monitor the recovery of these parameters 24 hours later. Additionally, the study evaluates the impact of fatigue on explosive power, measured by countermovement jump (CMJ) height, across these time points.
