Define "acute injury" in the context of sports.

An acute injury is defined as one that occurs suddenly during activity, often as a result of a specific traumatic event or impact. This type of injury is characterized by immediate pain and often requires prompt medical attention. In sports, acute injuries can include sprains, fractures, strains, or concussions, and they typically happen while performing a specific movement or action, such as jumping, running, or tackling. Recognizing the sudden onset is crucial, as it guides athletes and coaches in responding appropriately, such as administering first aid or seeking professional medical evaluation to address the injury effectively.

Other options may describe different circumstances: the gradual development of an injury aligns more with chronic injuries, while minor bruises or scrapes typically don't categorize as acute in severity. Additionally, injuries that happen during routine training could be acute or chronic, depending on the nature of the injury and its onset.
