The purpose of this study was to determine the difference in 40-yd dash and pro-agility time on artificial turf and natural grass. Twenty-four red-shirt freshmen college football players performed two trials each of a 40-yd dash and pro-agility run on each surface. The first test series was performed on the artificial turf, and the second test series on natural grass. Each sprint was timed by an electronic system and by 2 hand timers. Agility was timed on each surface by 2 hand timers. There was no significant difference between sprint times on turf (5.37 ± 0.30 s) and grass (5.36 ± 0.33 s). Hand timed sprints were significantly faster (5.12 ± 0.31 s) than electronically timed ones (5.36 ± 0.33 s). Agility times were significantly faster on turf (4.64 ± 0.28 s) than on grass (4.76 ± 0.32 s). Artificial turf may enhance some aspects of football performance and leave others unchanged.
