I have never heard of a NCAA BMI standard.
My conference will use a system that uses BMI along with body fat by age group, and waist size.
Example:
official 40-49 max body fat of 28.0 %, which is deemed obese = 28 points
waist max 40" = 40 points
BMI max 30 = 30 points
So if you exceed 98 points you would fail the standard.
You get a small amout of allowable body fat increase in each age group 30-39. 40-49. 50-59. 60-69 but not much, 60-69 max is 31.0
The BMI and waist size do not change with age.
We were given this in Sept so there is plenty of time to meet the standard for the 2011 season.
You could still be under the min standard and not be acceptable to the supervisor.
This is only one conference and not an NCAA standard.
