Fig. 3

EMG Traces for medial quadriceps and hamstrings (vastus medialis and semi-membranosus respectively), and lateral quadriceps and hamstrings (vastus lateralis and biceps femoris respectively). NB: Quad = quadricep; HS = hamstring; Rlxd = relaxed and observed on first step-up; Pre = pre-activated and observed on step-up with deliberate co-activation. 0 = timing of peak vastus medialis activation for all graphs (msec)
