10.3.2.Chronic injury
The second type of sports injury is called an overuse or chronic injury. Chronic injuries are those that happen over a period of time. Chronic injuries are usually the result of repetitive training, such as running, overhand throwing, or serving a ball in tennis. These include:

• stress fractures - tiny cracks in the bone's surface often caused by repetitive overloading (such as in the feet of a basketball player who is continuously jumping on the court)
• tendinitis - inflammation of the tendon caused by repetitive stretching
• epiphysitis or apophysitis - growth plate overload injuries such as Osgood-Schlatter disease
