Overuse injuries occur from stressing your joints, muscles, or other tissues without allowing them to recover. For example, throwing a baseball at high speeds over and over can stress your shoulder joint and cause an injury to part of that joint (the rotator cuff). Stress fractures, in which a bone breaks from the pressure placed on it through activity, are also common for athletes.
Overuse injuries can be caused by:
Doing too much too soon.
Doing intense exercise.
Not varying your activity or exercise routine.
Doing too much without proper conditioning.
Not using the proper form for the activity.
Not using proper equipment, such as wearing poorly fitting shoes.
