What Is It?
A Global Standard
For Athletic Speed
Just as VO2max gives you a precise, comparable measure of aerobic fitness, the Universal Speed Rating gives athletes a standardized, globally comparable score for their speed and athleticism.
The USR system uses a scientifically validated testing protocol to assess multiple dimensions of athletic speed, including acceleration, top-end velocity, first-step quickness, and change-of-direction ability, and converts them into a single, standardized score.
Your USR score is not just a number. It's a diagnostic tool that tells you exactly where you rank among athletes in your age group, sport, and position, and precisely where to focus your training to climb the ranks.
