What could be a general sign of an overuse injury in sports?

The persistent pain during activity signifies an overuse injury because it indicates that the body is experiencing stress and strain beyond its ability to recover. Overuse injuries often develop gradually as a result of repetitive motion or excessive loading on muscles, tendons, and joints without adequate rest or recovery time. This kind of pain arises when the tissues involved are unable to handle the repetitive forces being placed on them, leading to inflammation and discomfort during physical activity.

In contrast, sudden swelling can suggest acute injuries or trauma rather than the gradual onset typically seen in overuse injuries. Occasional soreness might simply point to normal muscle fatigue or minor strain, not necessarily indicating an injury. Minor bruising generally results from direct impact or trauma rather than repetitive stress, which is characteristic of overuse injuries. Thus, persistent pain during activity is a key indicator that should alert athletes and coaches to the potential for an overuse injury that needs to be addressed.
