Which of the following is NOT a health-related component of fitness?

• A. Cardiovascular endurance
• B. Muscular strength
• C. Muscular endurance
• D. Agility

Answer: (D)

Health-related components describe how the body supports overall health and daily functioning: cardiovascular endurance (heart and lung efficiency), muscular strength (maximal force a muscle can produce), muscular endurance (sustained or repeated muscle contractions), flexibility (range of motion), and body composition (balance of fat and lean mass). Agility, by contrast, is a skill-related attribute that reflects how quickly and accurately you can change direction, maintain balance, and coordinate movements. It relates more to athletic performance and neuromuscular coordination than to basic health status, so it isn’t classified as a health-related component. That’s why agility is the correct choice.
