  Why are body composition/BMI and the Cardio
   tests linked for the Physical Fitness Test?

• Body Composition is a critical factor in the
  exercise performances used to estimate aerobic
  capacity.
  Physically active youth will generally have levels of
         aerobic fitness and levels of fatness.

   It is possible for youth to be overweight and still be aerobically
    fit
                           and
  for youth to be of normal weight and be aerobically
       unfit.
