The primary function of the gluteus medius muscle is to move the hip and thigh outward, a movement called abduction. This is important for maintaining balance when standing on one leg, such as when walking or running.
The gluteus medius also helps to rotate the thigh inward, a movement called medial rotation. This movement is important for proper alignment of the legs and pelvis when walking or running.
In addition to these movement functions, the gluteus medius also plays a role in stabilizing the pelvis when standing on one leg. It works with other muscles in the hip and pelvis to maintain proper alignment and balance.
Weakness or imbalances in the gluteus medius can lead to problems with posture and gait, as well as lower back and hip pain. Exercises that target the gluteus medius, such as side leg raises, clamshells, and single leg squats, can help to strengthen and improve the function of this muscle.
