hamstrings. extend the hip and flex the knee against resistance and are important knee stabilizers. help control hip flexion in weightbearing position by contracting eccentrically when the flexion occurs in same direction as gravity as dead lift or hip=hinge position.
The main purpose of the complex is to flex the hip joint or lift the thigh bone up towards the pelvis/trunk. With enough strengthening and flexibility, it is strong enough to lift the leg higher than the waist or greater than 90 degrees. The Iliopsoas complex is a group of 3 muscles in the hip.There is one group in the right and one on the left. It consists of the Psoas Major muscle, the Iliacus muscle, and the Psoas Minor muscle.The first is the Psoas Major muscle which begins on the side of the low back from the T12 vertebra (the vertebra with the 12th rib to the L1 through L5 vertebrae (the lumbar spine or low back).he main purpose of the complex is to flex the hip joint or lift the thigh bone up towards the pelvis/trunk.
