Which of the following is NOT a defined injury type outlined in sport first aid practices?

Inflammatory injuries are not classified as a specific type of injury in sport first aid practices. While inflammation can occur as a response to various types of injuries—such as tension, compression, or shearing injuries—it itself describes a physiological process rather than a distinct injury type.

In sports medicine, the focus is on specific injury mechanisms and their effects on the body. Tension injuries refer to injuries caused by excessive stretching of tissues, compression injuries involve the compression of tissues leading to damage, and shearing injuries occur when forces are applied parallel to a surface, causing tissue damage. Each of these types has specific characteristics and treatment protocols associated with them, making them identifiable and manageable in the context of sports injuries.

Inflammation, however, is a broader concept that can result from various injury types. It often indicates a reaction to injury rather than defining a particular injury mechanism. Therefore, it does not fit the same category as the others listed, which are distinct injury types with unique presentations and treatments.
