Fig. 6. Time series of three-dimensional angular excursions of (A) limb joints and (B) body segments relative to the water surface for the identical run presented in Figs 3, 4, 5. The left footfall pattern is indicated above A. All joint angles (A) greater than 90° indicate joint extension, whereas all angles less than 90° indicate flexion. Open symbols indicate when the foot is out of the water, whereas closed symbols indicate that the foot is submerged.
