Which of the following are skill-related fitness components?

While agility is indeed a skill-related fitness component, flexibility is classified under health-related fitness components. Flexibility refers to the range of motion in joints and is crucial for overall mobility and injury prevention but does not directly enhance athletic performance as agility does. Thus, this combination fails to represent two skill-related components.

Power is a skill-related fitness component that refers to the ability to exert maximum force in a short time, while muscular endurance relates to the ability of muscles to sustain repeated contractions over time. Since muscular endurance is a health-related component, this option does not fully encapsulate two skill-related fitness components.

Speed is a skill-related fitness component, but muscular strength falls under health-related fitness. Muscular strength measures the maximum amount of force a muscle can exert, which is important for overall fitness but not specifically for skill-related performance. This option, therefore, combines one skill-related component with one health-related component.
