Ss (N = 12) performed maximal countermovement jumps with and without fatigue. Fatigue was induced by continuous jumping until a height of 70% of non-fatigued jumping was achieved.

Fatigued jumping was characterized by a longer contact time with the ground, an earlier movement initiation, and several differences in variables used to describe coordination. When movement time was normalized in relation to ground-contact time, the differences were removed. A consistent movement pattern was indicated with and without fatigue.

Implication. Vertical jumping involves a consistent movement pattern under non-fatigued and fatigued conditions. When performance deteriorates in fatigue, the overall time of each movement segment increases.
