Growing as people age, the elastic fibers of the striated muscle of control bones by connective tissue instead. Connective tissue, although very strong, but there is no flexibility, so the muscles become weak, not strong contraction. Old age, muscle strength decline, the reaction is slow. Older peop

As the age of the people has continued to grow, control activities of the bones of the stripes on the elastic fibers will be gradually replaced by connective tissue. Connective tissue while it is strong, but there is no elasticity, and therefore muscle becomes weak, not strong contraction. It is old

Grows unceasingly along with human's age, controls the skeletal muscle elastic fiber which the bone moves to be able gradually by the knot to contract the organization to replace.The knot contracts the organization although very solid, but does not have the elasticity, therefore the muscle becomes w

Growing as people get older, controlling the bone elasticity of activities of striated muscle fibers will be gradually replaced by connective tissue.
