- Supplementary Figure 1 - Tendon travel results for the plantaris of the example individual at the A) knee, with cruralis and associate connective tissue intact, B) ankle, and C) tarso-metatarsal joint, all in flexion/extension. Slope (mm per degree) is proportional to muscle moment arm. For the knee, slope is only calculated for angles greater than 100 degrees. In all cases, shortening of the muscle reduces displacement, and 180 degrees is fully extended
- Supplementary Figure 2 - Muscle-joint decoupling for all trials, as in Figure 2. Regressions from tendon travel experiment are in black; in vivo fascicle length - joint angle relationships in red. Each panel (A-D) represents a single individual.
