Which of the following is NOT a component of physical fitness?

Body composition analysis is not a component of physical fitness itself. Instead, it is a method used to assess the various elements that contribute to physical fitness. The main components of physical fitness typically include cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition.

Cardiovascular endurance refers to the ability of the heart and lungs to supply oxygen during sustained physical activity. Muscular strength indicates the amount of force a muscle can produce. Flexibility is the range of motion available at a joint. These components directly influence an individual's overall fitness level.

Body composition analysis, on the other hand, evaluates the proportions of fat and non-fat mass in the body. While it provides valuable information related to one's health and fitness, it is not classified as a component of physical fitness itself but rather a reflective metric that assists in understanding one’s physical fitness status.
