Which of the following is considered under body composition?

Body composition refers to the proportion of fat and non-fat mass in the body. It is a critical aspect of overall health and fitness because it provides insight into the distribution and total amount of body fat relative to muscle and other tissues. Body fat percentage is a direct measurement that indicates how much of your body weight is made up of fat.

By focusing on body fat percentage, one can assess their body composition, which can help in setting fitness goals, monitoring changes in weight, and understanding overall health risks associated with different levels of body fat. This aspect is essential in fitness and wellness pursuits, as it can be an indicator of both health status and physical fitness.

Other options like cardiovascular endurance, flexibility, and muscle hypertrophy relate to fitness capacities or physical skills rather than the actual makeup of the body in terms of fat and lean mass ratios. Cardiovascular endurance measures how well your body can perform aerobic activities, flexibility relates to the range of motion in joints, and muscle hypertrophy addresses the increase in muscle size. While all of these components contribute to overall fitness, they do not measure body composition directly.
