Sports medicine or sport medicine is an interdisciplinary subspecialty of medicine which deals with the treatment and preventive care of athletes, both amateur and professional. The team includes specialty physicians and surgeons, athletic trainers, physical therapists, coaches, other personnel, and, of course, the athlete.

Illness or injury in sport can be caused by many factors - from environmental to physiological and psychological. Consequently, sports medicine can encompass an array of specialties - cardiology, orthopaedic surgery, biomechanics, traumatology, etc. For example, heat, cold or altitude during training and competition can alter performance or may even be life threatening. What about the female triad of disordered eating, menstrual and bone density problems, and the pregnant or the aging athlete? In addition, the management of dermatological and endocrinological diseases and other such problems in the athlete demands expertise and sport-specific knowledge. The use of supplements, pharmacological or otherwise, and the topics of doping control and gender verification present complex moral, legal and health-related difficulties.

Then there are the particular problems associated with international sporting events, such as the effects of travel, acclimatization and the attempt to balance an athlete's participation and her or his health. Much of this represents new fields of study where extensive clinical and basic science research is burgeoning.

Finally, prevention is an area of increasingly specialized knowledge, interest and expertise.
