"Extreme" or tariff sports: their injuries and their prevention (with particular reference to diving, cheerleading, gymnastics, and figure skating).

The interface between sports medicine and performing arts medicine is closest for "tariff" sports, where the sportsperson can select their own programme of varying difficulty with the more complex skills carrying potential for higher marks. Inevitably, some performers over-reach themselves. Examples of injuries and prevention strategies to avoid such injuries are discussed in a preliminary analysis of four sports: diving, cheerleading, gymnastics, and figure skating.
