Which statement accurately describes the onset of gluteus maximus activation in the gait cycle?

• A. It begins in toe-off
• B. It begins at heel contact
• C. It begins during midstance
• D. It begins in terminal swing

Answer: (D)

Gluteus maximus activation begins in terminal swing. This timing sets up the hip for the transition from swing to stance: as the leg finishes swinging forward, the muscle starts to fire so that, at heel contact, the hip extension moment is ready to help stabilize the pelvis and control the forward momentum of the trunk and thigh. Activating just before ground contact allows the gluteus maximus to contribute to hip extension early in the stance phase, aiding weight acceptance and progression. Activation earlier (toe-off or midstance) or at heel contact itself would not provide the same anticipatory stabilization and hip-extensor support as late swing.
