Fig. 6. Net negative and positive work done at each joint, and total limb (forelimb on the top plot and hindlimb on the bottom plot) for each of the three speed ranges (slow <3.25 m s^–1, medium 3.25–4.00 m s^–1 and fast >4.00 m s^–1). FDIP and HDIP, fore and hind distal interphalangeal, respectively; MCP, metacarpophalangeal, MTP, metatarsophalangeal. Colored bars indicate the means, and black lines the standard deviation. *Significant differences (P<0.05 using repeated measures ANOVA) with speed. To obtain the total work for each joint and limb (as seen in Fig. 2), the negative and positive work are added together for each joint or for the total limb.
