Vibration exercise has a positive effect on bone. This is based upon Wolffe's law, which states that bone responds to the physical stresses put on it. Rapid muscular contractions will lead to increased strength and favorable stresses being placed on the bone.
Gentle rapid contractions allow the muscle to work as a pump, resulting in increased blood flow within the circulatory system. This allows the body to carry off waste products much faster, thereby enhancing circulation and recovery.
