“You mean that thing that’s going to tell me how fat I am?”
Yes, in fact, that’s exactly what it will do.
Study after study shows that there is a significant correlation between body composition and sport performance. Volleyball players don’t jump as high beyond a certain body fat percentage; softball players don’t get to second base as fast; swimmers who lose lean mass during the season are more likely to underperform.
College athletics is results-oriented, and like any results-oriented profession there are a set of best practices to follow. If body composition affects performance then it’s a best practice and we ought to measure it. How you feel about best practices is irrelevant (with obvious exceptions in the above case).
It’s likely you’ll work for a results-oriented organization in the future, and their best practices might make you uncomfortable too.
