negative value indicates valgus; positive value indicates varus. Pkf = Peak vertical ground reaction force, BW = body weight, KFlexCon = Knee flexion angle at initial contact, FPmax = Frontal plane knee angle at maximum knee flexion, FP30 = Maximum frontal plane angle at 30 degrees of knee flexion, FProm30 = Knee range of motion in the frontal plane from 0 degrees of knee flexion to 30 degrees of knee flexion, FPrommax = Knee range of motion in the frontal plane from 0 degrees of knee flexion to maximum knee flexion, VL = vastus lateralis muscle, VM = vastus medialis muscle, MH = medial hamstring muscles, LH = lateral hamstring muscle, GA = gastrocnemius muscle (Lateral head), * = RMS was normalized to a percent of the greatest RMS value, for that muscle, during the pre-fatigue condition.
