Figure 2.

A remarkable pattern was observed for some of the dependent measures, hip flexion at initial contact, A, hip flexion at peak stance, B, knee abduction at initial contact, C, knee-adduction moment at peak stance, D, and knee flexion at peak stance, E. These variables describe improved performance from prefatigue to 50% fatigue and a sudden decline from 50% to 100% fatigue. ^a Indicates less than at prefatigue and 50% fatigue. ^b Indicates less than at prefatigue. ^c Indicates less abducted than at 50% fatigue. ^d Indicates less than at 50% fatigue.
