Musculotendinous Stiffness of Triceps Surae, Maximal Rate of Force Development, and Vertical Jump Performance

Figure 2

(a) Determination of slopes α1, α2 and intercepts β1, β2 of the torque-stiffness relationship. Torque () is expressed as a fraction of the torque produced during a maximal voluntary contraction in isometric mode (). (b) Determination of the curvature index equal to the torque corresponding to half of the difference in stiffness at 0.4 and 0.8 .
