Figure 1

Representative set of muscle forces for the stance phase of gait. Muscles are semimembranosus (SM); semitendinosus (ST); long/short head of biceps femoris (BFL, BFS); rectus femoris (RF), vastus medialis, lateralis and intermedius (VM, VL, VI); medial/lateral gastrocnemius (MG, LG). The hamstrings and quadriceps are majorly active during loading response, with VL carrying the most force. Gastrocnemeii generate force primarily in the propulsive phase, with peak MG force being greater than that of LG.
