What is defined as an overuse injury?

An overuse injury is characterized by damage to a muscle, tendon, ligament, or joint caused by repetitive stress or strain over time, rather than a single traumatic event. This type of injury develops gradually as a result of continued physical activity, often without adequate rest or recovery. Examples include tendonitis, stress fractures, and bursitis, which frequently occur in sports or activities involving repetitive movements.

In contrast, an injury resulting from sudden trauma typically appears after a specific incident, such as a fall or collision, and does not fit the definition of an overuse injury. Inadequate hydration can lead to various conditions, but those are generally classified as dehydration-related issues rather than overuse injuries. Similarly, poor nutrition can affect overall performance and recovery but does not directly cause overuse injuries. Thus, the option that best defines an overuse injury is indeed the one that focuses on repetitive stress.
