One of the main factors affecting the accuracy of isokinetic parameters during maximum activation efforts is visual feedback. During a withdrawal reflex, the flexors in the withdrawing limb contract and the extensors relax, while in the other limb, the opposite occurs as part of the crossed extensor reflex. The abdominal muscles and back muscles are key components of this muscular network, and provide the strength to keep the body upright and for movement. The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex. The hip extensor group of muscles produce the greatest torque across the hip in comparison to the other hip Athletic injuries to the hip flexors and iliopsoas have been described in populations across all levels of competitive sports.
