One of the most contentious debates resonating throughout the world of sports is the impact on player safety posed by different playing surfaces, namely natural grass versus artificial turf. This crucial discussion encompasses not only football, but extends its relevance to soccer, various recreational activities and a broad cross-section of high school and college athletics, and hones its focus specifically on those sports wherein athletes are required to execute abrupt changes in direction that may lead to an undue strain on joints or result in torn ligaments.
Engaged in ongoing research, scientists are consistently exploring this issue, albeit with certain impediments. In order to derive accurate conclusions, a multitude of variables must be taken into account, such as the athletes’ age, fitness levels, prevailing weather and surface conditions, the type of footwear and the nature of injuries, which might be contact or spontaneous. Moreover, advancements in technology have led to significantly variable surfaces over the years, adding another layer of complexity to the ongoing research.
A tangible example stimulating this debate transpired when Aaron Rodgers, NFL player, suffered a torn Achilles’ tendon during a game played on artificial turf. Despite the likelihood of sustaining a similar injury on grass under those circumstances, the discussion pertaining to the dangers of artificial surfaces have been rekindled.
Drawing from various studies, it has been suggested that there is a discernible increase in the risk of foot and ankle injuries on artificial turf, regardless of the generational technology; although, the prevalence of knee and hip injuries remains consistent across both surfaces. Intriguingly, studies revealing a higher injury rate on grass have notably been funded by the artificial turf industry.
In the epicenter of professional football, the NFL, the players’ union has shown a preference for grass fields and has been advocating for the same. Conversely, the NFL management points out how certain artificial turf fields are seen to be safer than a few grass fields and aims to reduce injury rates across all playing surfaces.
The sporting community witnessed a nearly 20% increase in non-contact injuries on artificial turf compared to natural grass, based on an analytical study of NFL foot and leg injuries during the 2012-2016 regular season games.
Addressing the interplay between shoe cleats and playing surfaces, more athletes, particularly female ones, are encouraged to opt for specific cleats designs that interact more favorably with the artificial turf. Orthopedic surgeon Dr. Joseph Donnelly highlighted that lower torque levels are experienced when playing on grass, regardless of the style of cleats worn.
Beyond the paramount concern of player safety, financial angles and logistical feasibility come into play when considering the adoption of synthetic surfaces, especially for sizeable stadiums, which demand versatility for hosting a variety of events like concerts.
Looking forward, the industry is leaning towards hybrid fields, for instance, the Lambeau Field in Wisconsin which features a blend of Kentucky bluegrass sod mixed with synthetic fibers. Grass field technology continues to evolve, endorsing increased incorporation in sporting arenas as the overriding preference for the 2026 World Cup. This notable trend coupled with technology’s aiding hand suggests a bright yet safer future for athletes, regardless of the sporting arena.
