Question: 1 / 400

Which of the following is a key component of physical fitness?

Muscle strength

Flexibility

Cardiovascular endurance

Cardiovascular endurance is a key component of physical fitness as it measures the efficiency of the heart, lungs, and muscles during physical activity. This component is crucial because it reflects the body's ability to supply oxygen to working muscles and efficiently utilize that oxygen throughout exercise. Improved cardiovascular endurance results from consistent aerobic exercise and contributes to overall health by reducing the risk of chronic diseases, enhancing physical performance, and improving stamina for daily activities.

While muscle strength, flexibility, and body composition are important aspects of fitness, they serve different purposes and do not encompass the overall endurance capabilities that cardiovascular fitness entails. Therefore, recognizing cardiovascular endurance as a critical component helps in developing well-rounded fitness programs aimed at improving overall health and physical performance.
