How did fatigue fracture happen? How to prevent fatigue fracture?

In the case of exercise, some bones with concentrated stress will break part of trabecular bone, which is normal. The human body will repair and rebuild the trabecular bone without affecting the strength and hardness of the bone.

However, under the long-term and repeated stress stimulation, the fracture of trabecular bone increased, and the repair speed could not keep up with the fracture speed. Finally, all trabecular fractures occur in a certain stress concentration area, which leads to fractures.

Fatigue fractures mostly occur in tibia and metatarsal.

Therefore, as long as it is a long-distance walk, fatigue fractures may occur, and the prevention method is simple: rest more!
