Which of the following is NOT one of the five health-related physical fitness components?

The five health-related physical fitness components are essential aspects of fitness that are directly linked to good health and are important for overall well-being. These components include cardiorespiratory endurance, body composition, muscular strength, muscular endurance, and flexibility.

Power, while an important aspect of fitness, primarily relates to athletic performance and is considered a component of skill-related fitness rather than health-related fitness. Skill-related fitness includes components such as agility, balance, coordination, reaction time, and power, which are more related to athletic performance than to overall health. Therefore, the correct answer identifies power as not being part of the set of health-related physical fitness components.
