Setup for the fatigue-inducing exercise and measurement of MVCs. The complete setup is shown in (A) with the subject strapped into a chair with ball placement and leg straps included. The foot is positioned on a sliding foot plate (1) and foot adduction is achieved by the subject pushing their 1st metatarsal head against the dynamometer (3). The MVCs were measured by locking the foot plate while the subject pushed isometrically against the dynamometer. A pulley system that allowed the placement of weights (2) provided adjustable resistance while the subject performed the fatiguing exercise through a 30° range of motion (B).
