The Grass Versus Turf Debate

Grass versus turf: it may not seem like a big deal, but in the world of sports, the playing surface can be as crucial as the game itself. The debate over the safety of natural grass against artificial turf is a long-lived issue, intensifying with the evolution of playing surfaces and high-profile sports injuries. The argument does not solely affect professional leagues – it also influences high school and college athletics, and recreational sports.  

The Evolution of Playing Surfaces 

Artificial turf in athletics dates back to the 1960s, with the introduction of AstroTurf: specifically created for the Houston Astros’ Astrodome. AstroTurf, at the time, was a revolutionary surface that guaranteed lower maintenance costs and better durability than grass.  Since then, the technology has advanced significantly, leading to modernized and improved synthetic turf designed to mimic the feel of natural grass. However, the safety of artificial turf continuously stays a topic of discussion.  

Injury Risks: Grass vs. Turf 

Jets quarterback Aaron Rodger’s Achilles tendon injury in late 2023 ignited a new fire in the old debate. While injuries can occur on any surface, studies suggest a higher incidence of foot and ankle injuries on artificial turf. Recently, a group of researchers analyzed 53 articles on sports injuries published between 1972 and 2020. The studies suggested that artificial turf is associated with more injuries, particularly to the lower extremities, compared to natural grass.  

Dr. Calvin Hwang, a team physician for Stanford University and the San Jose Earthquakes, noted that while newer turf technologies may reduce some risks, the natural grass poses fewer dangers. Dr. Brian Cole, a team doctor for the Chicago Bulls, echoes this sentiment. Cole claims that the increased speed and agility on artificial surfaces can lead to more severe impacts in collision sports.  

The Role of Footwear 

The combination of footwear and playing surface is another crucial factor in sports safety. Dr. Joseph Donnelly, an orthopedic surgeon at Stanford Health Care, points out that certain cleat designs can worsen injury risks on artificial turf. For instance, the blade-shaped cleats can increase torsional forces on the knee, heightening the risk of ACL injuries, particularly among female athletes.   

Economic and Practical Considerations 

For athletic directors and facility managers, the choice between grass and turf often extends beyond safety concerns. Artificial turf offers a consistent playing surface and greater resilience under diverse weather conditions, making it an attractive possibility for multi-use venues and areas with difficult climates. However, despite its durability, turf is proven to garner higher injury rates in comparison to grass. Instead of accommodating cleats, the way a natural surface would, a turf limits the movement of a cleat and redirects the force back up the leg. 

While grass proves to be a safer playing surface, poorly maintained natural grass fields can also be hazardous. Grass needs significantly more upkeep and maintenance, thus requiring a larger chunk of your budget.  

Hybrid fields are a newer possibility for playing fields, combining natural grass with synthetic fibers, and presenting a promising compromise. These surfaces aim to provide the natural feel and safety benefits of grass with the durability of artificial turf. Notably, several NFL stadiums, including the Green Bay Packers’ Lambeau Field, have implemented hybrid surfaces, highlighting a growing trend toward these innovative solutions. 

The Future of Playing Surfaces 

The debate over grass versus turf is far from settled. Ongoing research aims to clarify the safety of different surfaces, considering variables such as player age, physical condition, and the type of footwear used. As the data evolves, so too will the approaches to ensuring athlete safety.  

It is important for athletic directors to weigh the pros and cons of each surface type, considering not only the safety and performance of athletes, but also the financial and logistical implications. The push for safer player conditions is also a workplace issue, as highlighted by the NFL Players Association Executive Director Lloyd Howell. The association has advocated for natural grass fields, citing data that suggests lower injury rates compared to artificial surfaces.  

As sports and technology continue to evolve, so must our understanding and management of the environments in which they are played. The decision between grass and turf is multifaceted, involving safety, cost, and practicality considerations. As hybrid and advanced artificial surfaces appear, they offer new opportunities for safer and more adaptable playing fields. However, the priority stays clear: ensuring the health and safety of athletes, whether they play on grass, turf, or a combination of both. As research continues to shed light on this complex issue, the hope is to reach a consensus that aligns the needs of athletes, managers, and the broader sports community.
