What is body composition?

• A. Ratio of fat to bone and muscle
• B. Range of movement around a joint
• C. Quickness of movement
• D. Maximal amount of force a muscle generates

Answer: (A)

Body composition is about the proportions of different tissues in the body, especially how much of the body is fat versus lean tissue such as bone and muscle. This helps explain how much of the body is fat and how much is lean tissue, which can influence health, energy use, and athletic performance. The statement describing the ratio of fat to bone and muscle captures this idea directly, since it compares fat tissue to the lean tissues that make up the rest of the body. The other descriptions refer to what the body can do: the range of movement around a joint is flexibility or mobility, quickness of movement is speed or agility, and the maximal amount of force a muscle generates is strength.
