Which muscle is likely tight in hyperlordosis?

1. Abdominals

2. Gluteus maximus

3. Ilipsoas

4. Rectus femoris

The correct answer is: Ilipsoas

In cases of hyperlordosis, the iliopsoas muscle is commonly tight due to its role in hip flexion and lumbar spine stabilization. Hyperlordosis is characterized by an excessive inward curvature of the lumbar spine, which can result from tightness in the hip flexors, particularly the iliopsoas. When the iliopsoas is tight, it can pull the pelvis forward, contributing to an increased arch in the lower back. The iliopsoas consists of the psoas major and iliacus muscles, both of which are crucial in maintaining proper hip and spinal mechanics. Increased tension in this muscle group often occurs as a compensatory response to prolonged sitting or a lack of proper stretching, further exacerbating the lordotic posture. In contrast, while other muscles, such as the abdominals, gluteus maximus, and rectus femoris, can also influence lumbar spine health and posture, they are not typically characterized by tightness in hyperlordosis. Specifically, the abdominals may actually become weak and lengthened, while the gluteus maximus may also be inhibited in this postural condition. The rectus femoris, being a part of the quadriceps group, may also experience lengthening
