Player preference
A recent survey of 1,511 active NFL players by the NFL players association found that 73% of the players preferred playing on a natural grass system, while only 18% preferred artificial turf (4). Nine-percent of the players had no preference.
Player injuries
There is a lack of research comparing injuries incurred on new in-fill artificial fields vs. natural grass fields (5). There are data indicating that the traditional artificial turf fields increased athlete injury, primarily due to increased surface hardness.
Although actual data are not available, anecdotal data are available from NFL players. Players were asked in a 2006 survey “Which surface do you think causes more soreness and fatigue to play on?”. Five-percent felt like natural grass systems increased fatigue, while 74% felt that artificial turf systems were more responsible for fatigue (5). Twenty-one percent felt they were the same. In the open comments section of the survey, the most common comment was “make all fields grass to prevent injuries.”
Potential increases in infections
An aspect of synthetic turf that is now receiving increased scrutiny is the potential for increased incidences of infections among players that play primarily on in-fill systems. In a report titled “Texas Football Succumbs to Virulent Staph Infection From Turf”, at least 276 football players were reported to be infected with an antibiotic-resistant staph infection, a rate of 517 for each 100,000 individuals (6). The U.S. Centers for Disease Control and Prevention in Atlanta reported a rate for the general population of 32 in 100,000. These infections were primarily associated with increased skin abrasions associated with synthetic turf and the risk of infection that might occur off the field from infections. In-fill systems must now be routinely treated with special disinfectants to reduce the likelihood of infections, adding another cost to the maintenance of these fields.
High temperatures
Artificial fields cannot be played on all the time due to temperature build-up on warm-sunny days. Artificial field surface temperatures have been documented as high as 199°F on a sunny day with an air temperature of 98°F (7). Researchers at Brigham Young University reported that the surface temperature of a synthetic football field on campus averaged 117°F, with a daily high of 157°F (8). On an adjacent natural grass field the surface temperature averaged 78°F, with a daily high of 89°F. Researchers at Penn State University studied the effect of using irrigation to reduce surface temperatures of synthetic fields and discovered that temperature could be decreased with irrigation, but the effects were short-lived (20 minutes) (9). Because of these high temperatures, an artificial field will remain largely unusable during warm days. Additionally, practicing on an artificial field could increase the incidence of heat stroke, muscle cramping, and overall athlete fatigue. Coaches holding practices on synthetic fields will need to monitor athlete health more closely and will need to limit the duration of practices on these surfaces to reduce the risk of athlete injury.
The images below comparing air, water, bermudagrass, sand, asphalt, and synthetic turf surface temperatures illustrate how hot a synthetic field can reach during a warm day.
