I think it is definitely a product of the increased attention on sports. Like it or not, sports brings people in, athletes and non-athletes alike. So there’s an added incentive to allowing athletes whose positions/events require specific body types to have accommodations.
I think an interesting debate question would be if the Academy should change its physical standards to have either an Academy standard with age accommodations or move to Fleet standards. On one end, exemplary physical fitness is definitely desired in officers. However, why should the Navy lose their investment when they separate a 25 yr old prior who would have passed in the Fleet since they couldn’t pass the 10:30/12:40 (M/F) 1.5 mi run time without any age accommodation.
