Figure 3


Fig. 3. Average values of the ankle (AA) knee (KA) and hip (HA) angles during running for all velocities and groups. The x-axis is normalised to the stride cycle (from heel strike to the next heel strike of the same foot). The vertical lines separate the contact and swing phases (mean ± 1 s.d.). Group 1, high running economy (N=10). Group 2, moderate running economy (N=12). Group 3, low running economy (N=6). (A) Velocity 1 (3.0 m s-1), (B) velocity 2 (3.5 m s-1), (C) velocity 3 (4.0 m s-1).
