Since the times of the 40 - yard dash in the professional field earlier ( and at amateur level continues ) were measured by hand, some of the details of any previous players have to be considered critical. The fastest electronically recorded time in the 40 - yard dash ran in 1999, the wide receiver Rondel Melendez in 2008 and the running back Chris Johnson, each with 4.24 seconds. For comparison, the former world record holder in the 100 - meter sprint, Maurice Green, a time of 9.82 seconds ran at the IAAF 2001 World Championships in Edmonton. He took 4.21 seconds for the first 40 yards.

The aforementioned Maurice Green measures 1.76 meters and weighs 75 kilograms, while 1.80 meters and 84 kilograms are in Fabian Washington. In this context, also noteworthy are the 4.35 seconds needed by the 1.97 -meter and 109 -pound Calvin Johnson 's 40 -yard sprint.
