[2 max]

body composition is composed of 2 main components, fat and fat-free mass ✔

fat-free mass is made up of water, bone and tissues such as muscle ✔

eg

for a power athlete like a shot putter/prop in rugby/sumo wrestler a higher level of fat mass does not limit performance ✔

Very few students were able to list the exact components to daily energy expenditure; instead many discussed general aspects when the markscheme required specific definitions.

There were many students who did not relate this question to fat vs. fat-free mass. Instead they tended to just discuss general aspects of body type and the benefits to certain sports.
