Whether it's innovations like Tommy John surgery for battered pitching arms or a Cheetah prosthesis that lets an amputee run as fast as two-legged sprinters, athletes have depended on sports medicine research. The work these researchers do drives the research toward a better understanding of sports injuries and the development of treatments that can keep athletes healthy. This title examines the science behind sports medicine research in the following chapters: What is Sports Medicine?; Concussion Research; Overuse Injuries; Athletes and Prostheses, and The Exciting Future of Sports Medicine.
