Are Your Tests Valid, Reliable, and Accurate? mikeyoungphd discussing some of the pitfalls associated with combine testing in the NFL. At Athletic Lab we try to minimize the error associated with testing. We strive for reliable, accurate, and valid test measures. If this is not the case, athletes who have been training for years may achieve a PR that wasn't actually a PR. It may have been starting in a different position, using different equipment, or cheating the test. As scientists and coaches, we hold ourselves to extremely rigorous standards, and try to use lab proven tests and methods. #sportscientist #sportscience #speedtest #sprinttest #NFL #football #rugby #rugbytraining #footballtraining
