IB Sports, exercise and health science B.3.1.1 Internal and External Risk Factors That Predispose Individuals to Injury Key Definitions

The ACL is a key ligament in the knee that stabilizes the joint by preventing excessive forward movement of the tibia relative to the femur.

Injury risk is the probability of sustaining an injury based on the interaction of internal and external risk factors.

Internal risk factors refer to variables inherent to the individual that can affect their susceptibility to injury.

The probability or chance that an injury will occur during a specific activity or event.

The magnitude of risk is a concept used to quantify the likelihood and severity of an injury occurring.

Conditions or circumstances that can increase the likelihood of an individual developing an injury or condition.

Age-related loss of muscle mass and strength, often preventable or reduced through regular physical activity.

The potential seriousness or consequences of the injury. This refers to how severe the injury could be if it occurs (e.g., minor sprain vs. severe fracture).
