Ankle jоint аngulаr displаcement curve during walking is presented belоw. Increased angle indicates dоrsiflexion and decreased angle indicates plantarflexion. Describe the work done by the ankle PLANTARFLEXOR muscles during phase 2 & 3 of the plot. During the Phase 2 of the gait cycle, the ankle joint is moving towards ________ (dorsi/plantar flexion). Because the ankle plantarflexor muscle torque and the ankle joint movement were in the ________ (same/opposite) direction(s), the muscles were performing __________ (positive/negative) work during this phase of gait. During the Phase 3 of the gait cycle, the ankle joint is moving towards ________ (dorsi/plantar flexion). Because the ankle plantarflexor muscle torque and the ankle joint movement were in the ________ (same/opposite) direction(s), the muscles were performing __________ (positive/negative) work during this phase of gait. Thus, the work done by the ankle plantarflexor muscles _________ (varies/does not change) during different phases of the gait cycle.
