The rectus femoris functions as an eccentric stabilizer to restrain or slow down posterior tilt of the pelvis at the hip joint during tasks requiring forceful hip extension, such as running or jumping. This is due to its attachment to the anterior inferior iliac spine and the superior border of the acetabulum, which allows it to act as a hip flexor and an anterior pelvic rotator.
