Movement Analysis Practice Test

Gluteus maximus remains active from heel contact to midstance to do what?

Produce knee flexion only Elevate the swing-side pelvis Support body weight and produce hip extension Extend the toes during swing

Correct Answer:

Support body weight and produce hip extension

Explanation:

During heel contact through early stance, the body’s weight tends to flex the hip and tip the trunk forward. The gluteus maximus acts as a powerful hip extensor and stabilizer to oppose that tendency, keeping the pelvis and trunk upright and controlling the forward collapse of the thigh. This stabilization also sets up the limb for forward progression into midstance, contributing to propulsion by extending the hip as weight is borne. That’s why the best choice describes both supporting body weight and producing hip extension. The other options don’t fit: knee flexion isn’t the gluteus maximus’s role, pelvis elevation of the swing side is handled by other hip abductors, and toe extension occurs in the foot, not at the hip.
