Fig. 1. Typical example of length and force traces of eccentric contractions as imposed during the eccentric exercise. Length (top panels) and force (bottom panels) traces during eccentric contractions of a medial gastrocnemius (GM) muscle. The first (A), 20th (B) and last (C) contraction of the eccentric fatiguing protocol are shown. The length of the muscle-tendon complex is expressed relative to the isometric optimum length for maximal stimulation (L_0,200Hz). The bold line below the force trace indicates stimulation.
