What does health-related physical fitness not include among its components?

Health-related physical fitness is generally classified into several key components that directly contribute to an individual's overall health and quality of life. These components typically include muscular strength, muscular endurance, cardiorespiratory fitness, flexibility, and body composition.

Agility, while an important aspect of physical fitness, falls under skill-related components rather than health-related components. Skill-related components focus on performance abilities that can enhance athletic performance, such as agility, balance, coordination, power, reaction time, and speed. In contrast, health-related fitness components are specifically aimed at improving health and functioning in everyday life.

Thus, agility does not contribute to health-related physical fitness as defined by its standard components, making it the correct choice in distinguishing between the different categories of fitness.
