Our brain is as important as any other muscle in an athlete’s body. Let’s develop its performance and functions, so we see more great plays, fewer injuries, and pure joy in the eyes of an athlete. Watching professional hockey, tennis, baseball, basketball, football, or other sports, we admire not only the athletes' performance, but more and more how smart they are, what play they can create. Mental, cognitive training is the new edge that helps athletes find the missing final margin, the difference between winning and losing. We know that synchronized development of their physical and mental skills improves their performance and makes them healthier, and happier members of winning teams. The “vehicle” we deliver the solution through is the environment of virtual and augmented reality.
