Table 2.

Fifteen separate trials were used to identify the passive moment-angle relationships. Shown are the approximate joint angles, joint excursions, and the muscles that were stretched. Positive angles represent hip flexion, knee flexion, and ankle dorsiflexion. Negative angles represent hip extension and ankle plantarflexion.
