Why might a person with a previous exercise injury be more likely to have a similar injury again?

A person with a previous injury may be more susceptible to recurring issues because prior injury is a recognized risk factor for conditions such as repetitive strain injury.

When tissues are subjected to repeated microtrauma, the body's normal repair process can be disrupted. This can lead to several long-term changes that alter the structural integrity of the affected area, including:

• Biomechanical changes: Alterations in the organization and type of collagen in tendons and ligaments can reduce their strength, compliance, and flexibility.1
• Tissue degradation: Chronic issues may result in scarring, muscle fiber loss, and reduced blood supply, which compromise the tissue's ability to function correctly under load.1
• Sensorimotor deficits: Previous injury can lead to poor sensorimotor feedback or a loss of fine motor control, which may increase the likelihood of further strain during physical activity.1

To mitigate these risks, physical therapy is often used to restore movement, improve muscle strength, and educate individuals on preventing future disability through proper posture and functional training.2
