Summary

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.

Conditions

  • Muscle Fatigue
  • Muscle Elasticity
  • Athletic Performance

Interventions

DEVICE

Isometric Plantar Flexion Fatigue Protocol

Participants undergo a localized isometric fatigue protocol in a supine position with their feet placed against a solid wall. They perform maximal isometric plantar flexion pushing against the wall. The protocol continues until the participant reports a score of 8 or higher (indicating 'very strong' to 'maximal' exertion) on the Borg CR-10 Scale. Task failure is also confirmed by the inability to maintain the required isometric pressure or foot position despite verbal encouragement. This ensures a standardized level of subjective and objective muscle fatigue across all participants.
