What is the primary role of the gluteal muscles at toe off?

The primary role of the gluteal muscles at toe off is to produce hip extension. During the gait cycle, particularly at the toe-off phase of the stance, the body transitions from support to propulsion. The gluteus maximus, the main extensor of the hip, contracts to extend the hip joint, which helps to propel the body forward. This extension is crucial as it provides the necessary power to push off the ground effectively, enabling movement into the next phase of walking or running.

Additionally, the activation of the gluteal muscles during this phase stabilizes the pelvis and assists in maintaining a balanced gait. While the other functions such as hip flexion counteraction, hip abduction, and limiting lateral rotation are also important aspects of gluteal muscle function, the core action at toe-off is primarily focused on hip extension to facilitate Forward propulsion.
