Abstract

This study investigates the effects of the eyes-closed condition on lower limb muscle activation, ground reaction force, and three-dimensional kinematics during repeated countermovement jumps in healthy young male adults. Data were collected in a controlled laboratory setting using a force platform, 3D motion capture, and wireless electromyography. The results offer insight into the interplay between sensory re-weighting and motor control under altered visual conditions. While key performance parameters remain largely consistent between eyes-open and eyes-closed trials, subtle differences in joint kinematics suggest compensatory adaptations may occur. These findings contribute to a better understanding of sensory integration in dynamic motor tasks within this specific population.
