The professional world, mostly. The people that have the most to gain are the least likely to look into stuff like this.

The Moneyball revolution in sports has taken over front offices, scouting departments, and stats geeks. But not the holiest of holies, the world of player development. Keeping a player on the court for a few extra minutes per game could result in a huge gain for the team. Keeping Lebron James or Troy Tulowitzki healthy could literally be worth $20 million or more to the team. Yet they pay nothing on that side of the game and do not look for new avenues or approaches.

It is insanity. But it is also professional sports, so, it is what it is. Eventually, there will be a revolution. I only hope it's within the next 20 years.
