Generate Ideas The leg muscles that are active during the gait cycle are the gluteus maximus, iliopsoas, hamstrings, quadriceps, triceps surae, and tibialis anterior. During initial contact, the gluteus maximus, hamstrings, quadriceps, and tibialis anterior are active. At opposite toe off, the activity of the gluteus maximus is just beginning to decline, while the activity of the quadriceps is at its peak. Also at that moment the activity of the hamstrings is almost to zero and the activity of the tibialis anterior is decreased to halfway from its peak. At heel rise, the activity of the triceps surae is halfway to its peak activity, while there is no other activity in any of the other leg muscles. At opposite initial contact the activity of the triceps surae is halfway down from its peak, while the activity of the quadriceps is just beginning to increase. At toe off there is a good amount of activity in the iliopsoas, quadriceps, and tibialis anterior. At feet adjacent position, there is activity in the ilipsoas and the tibialis anterior, but the activity in both the muscles decreasing at that moment. At the tibia vertical position the activity in the hamstrings and quadriceps is just beginning to increase from zero activity, and there is also activity in the tibialis anterior, which is increasing at that moment. The triceps surae are activated at the beginning of the single limb support phase. The quadriceps are activated at the beginning of the second double support phase. The iliopsoas is activated right after the quadriceps at the beginning of the second double support phase. The gluteus maximus is activated right before initial contact in the right leg swing phase. The hamstrings are activated right in the middle of the right leg swing phase. The quadriceps are also activate again right when the right when the tibia is vertical in the right
