- The main cause of swimming injuries is overuse
- As a swimmer fatigues the use of proper swimming technique decreases, causing stress on the muscles and joints that are already under stress from repetitive motions
- Even a minor injury can progress to a serious injury due to the volume and intensity of swimming. Mild irritation of the shoulder can result in shoulder instability with severe pain.
- Overuse injuries may occur at the knee from kicking or pushing of the wall, at the hip from the breaststroke kick, and in the back from the butterfly dolphin kick
