010-111 Question #129: Real Exam Question with Answer & Explanation

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.

Question

Which four extrinsic risk factors may be associated with an increased risk of musculoskeletal injury?

Options

ARestricted range of motion, previous injury, adverse environmental conditions, faulty equipment
BAdverse environmental conditions, muscle weakness and imbalance, body composition, faulty
CExcessive Load on the body, training errors, adverse environmental conditions, faulty equipment
DBony alignment abnormalities, joint laxity, training errors, faulty equipment

Explanation

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.

Common mistakes.

A. 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.
B. Muscle weakness and imbalance and body composition are intrinsic factors because they reflect internal physical characteristics of the individual rather than outside variables.
D. Bony alignment abnormalities and joint laxity are intrinsic factors because they are anatomical and structural traits inherent to the individual's body.
