THE EFFECT OF RESTRICTING THE VISUAL SENSE ON THE KINEMATICS AND KINETICS OF A CUTTING MANOEUVRE

Abstract

The purpose of this study is to investigate the kinematic and kinetic parameters when performing a cutting manoeuvre blindfolded. Male rugby and football players (n=7) performed a 60 degree cutting manoeuvre blindfolded and without restriction while recording kinetic and kinematic data. Restricting the vision led to a significant decrease of knee and hip flexion angle, a decreased inversion in the ankle and a tendency for higher knee-stiffness in the sagittal plane. The hip joint moment was significantly reduced while the knee joint moment was significantly increased. Considerable effects occurred in the kinematic and kinetic parameters, while the approach velocity and contact time showed trivial effects.
