Fig. 4. Trajectory of a jump. The position of the left and right eyes (see cartoon inset) in the vertical plane are plotted against time. Selected frames to show the orientation of the body are shown at the times indicated. Once airborne the body spins about the longitudinal axis of the body with each rotation lasting about 4 ms, as indicated by the periodic convergence of the two sets of points at these intervals. Images were captured at 2000 s^–1.
