Sports and physical activity are becoming more important and more emphasized in the lives of the average person as the health benefits of maintaining an active lifestyle are recognized. In the past most people were primarily active in sports during their time in school. The trend is for more people to continue vigorous activity through middle age and beyond. In addition, as high level athletes continue to reach higher levels of performance more amateur athletes attempt to reach similar levels of intensity, which they may not be able to handle with their level or method of training. This has led to an increase in overuse injuries and chronic tendon injuries. It has been estimated that overuse type injuries account for 30-50% of sports injuries (1).
