The hazards of low skeletal muscle in women are mainly the following: a. Slowed blood circulation: due to weak muscle strength and power, it will lead to slowed blood circulation throughout the body, mainly because skeletal muscle can play the role of muscle pump to promote venous return, so patients will have cold limbs, limb strength weakening and other hazards. Second, the joint stability becomes poor: female skeletal muscle strength and strength is weaker, but also make the joint stability becomes poor, the daily wear and tear of the joint will continue to increase, prone to joint trauma, degenerative changes in joint cartilage, resulting in serious osteoarthritis, joint life will be significantly shortened. Therefore, if girls have low skeletal muscle, attention should be paid to strengthening exercise, increase nutrition, so that the strength and intensity of skeletal muscle back to normal levels, in order to avoid the adverse effects.
