Which factor is described as causing different optimum weights among athletes of the same height due to frame size?

• A. Height
• B. Bone structure
• C. Muscle girth
• D. Gender

Answer: (B)

Frame size is the factor described. The size of your skeleton, or bone structure, defines your frame size. A larger frame has thicker bones and a wider torso and pelvis, adding bone mass and allowing more lean tissue, so the optimum weight for that height is higher. A smaller frame carries less bone mass, so the healthy weight is lower. Height is constant and doesn’t explain these differences, while muscle girth reflects current muscle mass rather than the stable frame, and gender affects typical body composition but not the frame-size concept being described.
