Which of the following are components of physical fitness?

The components of physical fitness are typically classified into health-related and skill-related categories. Option B includes cardiovascular endurance, muscular strength, and flexibility, which are all recognized as essential components of health-related physical fitness.

Cardiovascular endurance refers to the efficiency of the heart and lungs to supply oxygen to the body during prolonged physical activity. Muscular strength is the ability of a muscle or muscle group to exert force against resistance, and flexibility is the range of motion available at a joint. These components are critical for overall health and performance in daily activities as well as in athletic endeavors.

In contrast, other options contain some elements that may contribute to physical performance but are not classified as foundational components of physical fitness. For example, speed, agility, and coordination relate more to skill-related fitness aspects, impacting athletic performance but not necessarily overall health fitness. Body mass index, muscle mass, and fat percentage are measures used in health assessments but do not directly classify the physical fitness components themselves. Finally, power, balance, and neurological efficiency also pertain more to performance abilities and skill-related aspects rather than being direct constituents of physical fitness.
