Australian rules football injuries
Australian rules football is a sport known for its high level of physical body contact compared to other ball sports such as soccer and basketball, as upper body tackling is legal in a similar fashion to the rugby codes and American football. High-impact collisions can occur from any direction, although deliberate collisions sometimes occur from a front-on direction (known specifically within the code as a "shirtfront" when the contact is a body-on-body collision). In addition, players of the code typically wear no protective padding of any kind except for a mouthguard or, occasionally, a helmet (unlike the full-body gear in gridiron football codes or the shin guards in soccer). As such, injury rates tend to be high.
