Sagittal plane knee angles of the weight-bearing leg. a Knee flexion-extension angles over a GC. The solid lines represent the medians, the shaded areas represent the range of all GCs, and the dashed vertical lines represent the mean of the TO events. b–e Summary statistics of the 1st knee flexion peak (b) and its timing (c), and the 2nd knee flexion peak (d) and its timing (e). The black horizontal lines indicate nonsignificant differences
