From: Contribution of non-extensor muscles of the leg to maximal-effort countermovement jumping
The musculotendon model utilized in this study. The musculotendon model was composed of a contractile element (CE) and a series elastic element (SEE). The effect of pennation angle (αpen) was also taken into consideration. The contractile element had the force-length-velocity relation, and the series elastic element had a non-linear force-length relation.
