Gluteal medius m. (臀中肌)的重要性

The gluteal medius and leg abduction are used in all sports requiring side stepping or movement to the side (lateral movement)
Leg abduction is also the key action in shifting your body weight in the hitting and throwing sports.
The gluteal medius plays an important role in walking and running by keeping the pelvis level. When the muscle is weak, your hips will drop on the side of the swing leg and in time this can cause back problems. Body-builder need the muscle development for shapely sides of the hips.
