(苏州大学 体育学院,江苏 苏州 215021) 摘 要:运动性骨疲劳作为骨代谢的一个研究分支,因其在疲劳性骨折中的重要作用近年来引起人们的高度关注。骨疲劳可能通过与日俱增的疲劳微损伤和过多的骨重建演变成疲劳性骨折,同时也可通过积极的反馈机制避免骨折的发生。就运动性骨疲劳的性别和运动项目特点、运动性骨疲劳发生的可能机理、适宜运动对骨的保护性作用等方面的研究进展进行了综述评价。 |

(School of Sports Science,Soochow University,Suzhou 215021,China) Abstract: Exercise induced bone fatigue is puzzled by athletes and military trainers. 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. |
