Which postural distortion is characterized by anterior pelvic tilt and excessive lordosis (extension) of the lumbar spine?

The correct choice reflects lower crossed syndrome, which is defined by specific muscular imbalances leading to postural distortions. This condition is characterized by an anterior pelvic tilt and an excessive lordotic curve in the lumbar spine.

In lower crossed syndrome, the muscle groups on the anterior side of the pelvis, such as the hip flexors, become tight and shortened. Meanwhile, the muscles that are supposed to support the pelvis and lumbar spine, such as the gluteal muscles and the abdominal muscles, tend to be weak and lengthened. This imbalance results in the characteristic pelvic tilt and exaggerated lumbar curvature that defines this syndrome.

Understanding how these muscular imbalances interact is crucial for creating effective correction strategies in a fitness program. This includes focusing on strengthening the gluteal and abdominal muscles while stretching the hip flexors, ultimately promoting better posture and movement efficiency.

Other choices represent different postural distortions. For instance, upper crossed syndrome involves imbalances in the upper body, specifically between the neck and shoulder regions, leading to rounded shoulders and forward head posture. Flat back syndrome typically features a straightened lower back with a posterior pelvic tilt, conflicting with the excessive lordosis seen in lower crossed syndrome. Sway back syndrome, on the other hand, involves a
