Body composition refers to the proportions of which three components in the body?

Body composition is defined as the relative proportions of fat, muscle, and bone in the human body. This measurement is crucial for assessing an individual's overall fitness and health, as it provides insight into their metabolic health and physical capabilities.

Fat, particularly, is a critical component because it plays roles in energy storage, insulation, and hormone production. Muscle contributes to strength, metabolism, and overall functional capacity, while bone density is important for support and protection of vital organs. Understanding these three components allows for better health assessments and fitness programming tailored to an individual’s goals.

The other choices do not accurately reflect the standard components used to measure body composition. Muscle and fat are present in a variety of forms, while bone plays a key role in structural integrity, making them central to the concept of body composition.
