The components of health-related physical fitness specifically include cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Each of these elements plays a crucial role in overall health and physical performance.

Cardiovascular endurance refers to the ability of the heart and lungs to supply oxygen to the muscles during prolonged physical activity, which is essential for activities such as running, cycling, and swimming. Muscular strength is the maximum amount of force that a muscle or group of muscles can exert, important for daily tasks and injury prevention. Muscular endurance relates to the ability of a muscle to sustain repeated contractions over time, vital for activities like weightlifting or sports that require prolonged physical exertion. Flexibility involves the range of motion around a joint and is necessary for performing movements efficiently and preventing injuries. Body composition reflects the proportions of fat and non-fat mass in the body, influencing overall health and fitness levels.

The other choices include components more aligned with performance-related fitness, which focuses on skills relevant to athletic performance rather than general health benefits. For instance, agility, balance, and speed are essential for sports-specific training but do not directly correlate with overall health-related fitness, making the correct choice focused on health outcomes rather than athletic performance.
