Injuries occur in two ways; externally or internally.

An externally caused injury might involve someone bumping into you, impacting on your body to cause a fracture or dislocation. The external environment also brings risks, like dehydration in severe heat.

Internally, sudden movements can tear and strain muscles, something that’s also possible from overuse. Chronic injuries arise when a condition is left untreated. The type of injury could be mild or severe, like an ‘open fracture’, when bones break and come out through the skin. Ouch!

Causes of injury

Injuries in sport happen as a result of external force from outside your body or internal force from inside your body.

Impact injuries are common in invasion sports

There are two types:

  • Impact with someone (tackle, collision, punch, kick) or something (landing hard, running into a post). These cause bruises, sprains, fractures, dislocations or concussion.
  • The environment – very hot or cold conditions. Heat causes dehydration. Cold causes hypothermia.

Internal Force

Very sudden, powerful movements can tear or strain muscles and tendons.
