What factors may cause a normative value to be non-applicable to an individual?

• A. Injury or medical conditions only.
• B. Unique athletic specialties only.
• C. Significant deviations in body size or training history from the reference group.
• D. Injury, medical conditions, unique athletic specialties, or significant deviations in body size or training history from the reference group.

Answer: (B)

Normative values are based on a reference group, so they apply best when an individual matches that group in key aspects. If something about you differs in meaningful ways, those norms may not apply. Injury or medical conditions can change how you perform or recover, altering physiology or mechanics from the reference standard. Unique athletic specialties push your body in directions the general norms don’t account for, so your performance profile can diverge from the norm. Significant deviations in body size or training history also shift baseline capabilities, meaning someone much different in size or with a different training background may not fit the reference values. The most complete option acknowledges all of these possibilities—that any of them, alone or in combination, can make a normative value non-applicable.
