Knee kinematics Is altered post-fatigue while performing^ a crossover task

摘要

Purpose To examine the effect of a sequential fatigue protocol on lower extremity biomechanics during a crossover cutting task in female soccer players. Methods Eighteen female collegiate soccer players alternated between a fatigue protocol and two consecutive unanticipated crossover trials until fatigue was reached. Lower extremity biomechanics were evaluated during the crossover using a 3D motion capture system and two force plates. Repeated-measures AJSTOVAs analysed differences between three sequential stages of fatigue (pre, 50, 100 %) for each dependent variable (a = 0.05).
