The Australasian College of Sports Physicians (ACSP) is the professional body representing sports physicians in both Australia and New Zealand. Sports physicians are committed to excellence in the practice of medicine as it applies to all aspects of physical activity. Safe and effective sporting performance at all levels is a major focus. Alongside this is the increasing recognition of the importance of exercise in the prevention and treatment of common and often serious medical conditions, such as arthritis, heart disease, diabetes and many cancers. Exercise does not replace traditional measures such as surgery, medication and rest in many of these conditions, but it can improve recovery and greatly improve long term outcomes.
