Which action(s) can the gluteus maximus perform?

The gluteus maximus is a powerful muscle located in the posterior hip, and it plays a crucial role in various movements of the hip joint. Understanding its actions is essential for effective corrective exercises.

Hip extension is one of the primary functions of the gluteus maximus. During this movement, the muscle contracts to pull the thigh backward, which is especially important during activities like standing up, climbing stairs, and running.

In addition to extending the hip, the gluteus maximus also assists in external rotation of the hip. This action involves rotating the thigh outward, which is significant for maintaining proper alignment and stability of the hip joint during various physical activities.

Furthermore, the gluteus maximus contributes to abduction. While this is not its primary function (that role is mainly fulfilled by the gluteus medius and minimus), the gluteus maximus aids in moving the thigh away from the center of the body, particularly when the hip is in a flexed position.

Given these multiple roles — hip extension, external rotation, and assistance with abduction — the gluteus maximus is a multifaceted muscle involved in a wide range of movements. Thus, the answer that encompasses all these actions accurately reflects the muscle's
