What are the health-related components of fitness?

The health-related components of fitness are crucial for overall health and well-being, and they primarily focus on aspects that benefit physical health rather than athletic performance alone. The correct choice includes flexibility, muscular strength/endurance, and cardiorespiratory endurance, which are all essential for maintaining a healthy body.

Flexibility contributes to the range of motion of joints and can prevent injuries. Muscular strength and endurance are important for performing daily activities and supporting metabolic health, while cardiorespiratory endurance is vital for heart and lung health, influencing overall stamina and the body's ability to perform sustained activity.

The other choices include components that emphasize performance in sports or physical activities rather than general health. For instance, speed, power, and agility are more related to athletic performance, while reaction time, coordination, and balance focus on skills necessary for sports rather than health. Similarly, endurance, explosiveness, and mental toughness pertain to performance aspects and psychological resilience, which do not directly correlate with the health-related components of fitness.
