Just like any other tissue in our body, bones adapt to stresses that we put them trough. When we walk, run or jump, forces that go through your body can be as high as 12 times your body weight.
That is a lot of pressure on your bones! For bones to be able to absorb that much weight, they need to get stronger. However, contrary to muscles for example, bones take much longer to adapt.
Whenever you do any physical activity, your bones undergo microscopic damage. When you sleep and eat properly, the body can heal this microscopic damage and make bones stronger over time.
However, if you train too much and do not eat/sleep properly, your body cannot keep up with these accumulated stresses, and bones start to weaken. Eventually, bones get so weak that this leads to a fracture - a small crack within the bones.
Individuals who acquire stress fracture often describe a localized discomfort somewhere along the bone. Many individuals will have an excruciating pain upon palpating the tender spot. This discomfort gets worse with more physical activity until it reaches a point where any weight bearing causes pain.
Compared to any other sport, stress fractures are most common in running and they tend to occur most frequently in shin bones (tibia and fibula), followed by thigh bone (femur) and foot bones (metatarsal and navicular bone).
