010-111 · Question #129
Which four extrinsic risk factors may be associated with an increased risk of musculoskeletal injury?
The correct answer is C. Excessive Load on the body, training errors, adverse environmental conditions, faulty equipment. Extrinsic risk factors for musculoskeletal injury originate outside the individual and include training-related and environmental variables, as opposed to intrinsic factors which reflect the individual's internal physiology. Only answer C lists exclusively extrinsic factors.

Why each option
Extrinsic risk factors for musculoskeletal injury originate outside the individual and include training-related and environmental variables, as opposed to intrinsic factors which reflect the individual's internal physiology. Only answer C lists exclusively extrinsic factors.
Restricted range of motion and previous injury are intrinsic factors because they describe the individual's own physiological state and injury history, not external conditions.
Muscle weakness and imbalance and body composition are intrinsic factors because they reflect internal physical characteristics of the individual rather than outside variables.
Excessive load on the body, training errors, adverse environmental conditions, and faulty equipment are all extrinsic factors because they exist outside the individual's own biology and can be modified by altering the training stimulus or environment. Extrinsic factors are contrasted with intrinsic factors such as joint laxity or prior injury, which are internal to the person. All four items in choice C are external influences that a trainer or athlete can adjust to reduce injury risk.
Bony alignment abnormalities and joint laxity are intrinsic factors because they are anatomical and structural traits inherent to the individual's body.
