Document Summary
Day 14 20/10/16 exercise, diet, and weight control: outline. Bmi = kg/m2; this is not % fat. Measure used to assess obesity in large epidemiological studies. Underestimates those with a small musculoskeletal system. Ok for large studies but not good for individual (not very accurate) Does not take into account muscle mass. Densitometry = mass/volume (higher density = less % fat) (lower density = more % fat) Volume taken via water displacement or air displacement. Muscle and bone are more dense than fat, therefore more dense a person is the lower. Error primarily in converting from density to % fat. Does not take into account density of bones - assume the same if bones are denser than the normal it will throw it off (-% body fat) If bones are less dense than the normal it will throw it off (higher % body fat) Measure the density of the body but uses air instead of water.
