Fig. 3. Joint angles, moments and powers for the forelimb (shoulder, A; elbow, B; wrist, C; MCP, metacarpophalangeal, D; FDIP, forelimb distal interphalangeal, E). The blue line represents slow speeds (<3.25 m s^–1), the red line medium speeds (3.25–4.00 m s^–1) and the grey line fast speeds (>4.0 m s^–1). The error bars on each curve are the standard deviation. The stick figure representations at the top are from every 20% of stance of the forelimb from one medium speed trial (with the same orientation as the forelimb in Fig. 1) with the direction and magnitude of the resultant ground reaction force included as a broken line.
