Which of the following is a health-related fitness component?

• A. Flexibility
• B. Agility
• C. Power
• D. Reaction time

Answer: (A)

Health-related fitness components reflect overall health and everyday functional ability. Flexibility fits here because it describes how well joints and muscles move through a full range of motion, which affects posture, movement efficiency, and the ability to perform daily tasks without injury. When you can stretch and move through your joints comfortably, you’re better prepared to handle everyday activities and reduce the risk of strains. On the other hand, agility, power, and reaction time center on performing specific skills and athletic tasks—quick direction changes, maximal force generation, and rapid responses—so they’re considered skill-related fitness components rather than measures of general health.
