Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Knee joint position sense will be assessed before and immediately after the fatigue protocols/control condition, through active concentric and eccentric positionings/repositionings, in sitting and prone positions, to a target range of 45º of knee flexion in an isokinetic dynamometer. Surface electromyography electrodes will also be placed on the vastus lateralis and biceps femoris during all procedures.
