In recent years, bone fatigue has become an serious problem in international bone mechanics and medical research, the bone fatigue play a decisive role in bone fatigue fractures . Bone fatigue may be into fractures by the excessive micro-damage. Because of fatigue fracture, the athletes will lose about 10-13 weeks of training, it is very cruel to the athletes who are participating in the competition; At the same time, bone fatigue may also occur through a positive feedback mechanism to avoid the occurrence of fracture. So, under the fatigue load, it is not very clear that internal changes in bone have taken place. Therefore, relationship among load, fatigue and the accumulation of micro-damage is particularly important in the bone biomechanics and bone biological nature and the development of bone fatigue.
