For example, the gluteals are used during walking or climbing steps. 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 men had significantly larger type I fiber areas (4597 vs 3483 microns2) and mean fiber areas (6632 vs 3963 microns2) than the women in biceps brachii and significantly larger type II fiber areas (7700 vs 4040 microns2) and mean fiber areas (7070 vs 4290 microns2) in vastus lateralis. Another key structure in low back pain is the hamstring muscles, the large muscles in the back of the thighs. See. Without specific back and abdominal exercises to target these muscles, they will naturally weaken over time, increasing the chance of developing or worsening back pain. Careers.
