RELIABILITY AND SMALLEST WORTHWHILE DIFFERENCE OF THE NFL-225 TEST IN NCAA DIVISION I FOOTBALL PLAYERS.

The article reports on research conducted to investigate the reliability and smallest worthwhile difference in the National Football League-225 test in National Collegiate Athletic Association division one football players. Researchers evaluated the test with 72 players. They found that a small technical error provided strong reliability and that the smallest worthwhile difference suggested that change in performance of three repetitions or more after training would improve the test's performance.
