Final answer:
Excessive anterior pelvic tilt is typically associated with weakness of the gluteus maximus and abdominal muscles. The gluteal group, consisting of gluteus maximus, medius, and minimus, is the large muscle group attaching the leg to the pelvic girdle and is responsible for extending the hip joint.
Step-by-step explanation:
An excessive anterior pelvic tilt is typically associated with weakness or inhibition of the gluteus maximus and abdominal muscles. When these muscle groups are weak, they cannot effectively counteract the pull of the relatively tighter and stronger opposing muscle groups, such as the hip flexors and erector spinae of the lower back, which can result in an increased curvature of the lower back, or hyperlordosis. Strengthening the gluteal muscles and abdominals is often recommended to help correct or reduce excessive anterior pelvic tilt.
The large muscle group that attaches the leg to the pelvic girdle and produces extension of the hip joint is the gluteal group. In the gluteal region, the large and strong muscles, specifically the gluteus maximus, gluteus medius, and gluteus minimus, are responsible for extending and abducting the femur. These gluteal muscles are essential for stable hip movement and provide powerful motions needed for activities such as walking, running, and climbing.
