We looked at various data from the weight certification process conducted by state high school wrestling associations during the 2016-17 season. For the 226,000 wrestlers in the database, average fat percentage at certification was 16.9%, up slightly from 16.6% in the previous year.
By grade, fat percentage at certification dips for eight graders then trends back up and levels off in 10th grade.
By minimum weight class, average fat percentage looks very similar to the last two seasons.
Lastly, a look at fat percentage at certification by state.
New Mexico sure has some lean wrestlers! Note that the two states with the highest fat percentage at certification -- Oklahoma and Texas -- are the same two states that added the most wrestlers from 2010-11 to 2015-16. Hmmm.
