Modern Artificial Turf | 3 points of safety
PREVENTING CONCUSSIONS IN SPORTS HAS BECOME A NATIONAL PRIORITY. STUDIES SHOW 1 IN 5 CONCUSSIONS OCCURS BY A HEAD TO SURFACE IMPACT. AND HIGHER ENERGY IMPACTS BETWEEN THE BODY AND THE SURFACE ALSO TAKE THEIR TOLL.
HEAD INJURY CRITERI0N (HIC); ASTM F355-E missile
The HIC test correlates with the likelihood and severity of a head injury, has been used to test playground surfaces for decades, and was adopted by ASTM for athletic fields in 2016. The HIC impact test drops a 10.1 lb. hemisphere projectile (curved like a human head) multiple times from increasing heights and determines the Critical Fall Height of the surface. The higher the Critical Fall Height, the safer the surface. A good natural grass field will produce a minimum critical fall height of about 6 feet or higher. Doing both the Gmax and HIC tests gives a more comprehensive picture of how the field is performing from an impact safety standpoint.
GMAX; F355-A MISSILE
The GMax test is not correlated with head injury risk. The GMax test drops a 20 lb. flat missile from just 2 feet high. The higher the GMax value, the harder the surface. A good natural grass field (the benchmark for a quality athletic field) will produce a GMax below 100, and often below 80.
Artificial turf over stone will produce a GMax above 140 and frequently higher, meaning far more impact energy is absorbed by the body rather than by the surface. Turf over a Brock Shock Pad will mimic the low Gmax of natural grass without making the field soft to run on. (Study: University of TN Dept. of Biomechanics, 2016)

Only turf over a Shock Pad can reach safety ranges found in natural grass.
UNDERSTANDING THE TEST
The Head Injury Criterion Test or “HIC” Test is an important, if not the most important, test for judging safety in an artificial turf field. The HIC Test identifies “Critical Fall Heights” for surfaces, so you know the risk of a critical head injuries for falls at varying heights. You want your field to have the highest critical fall height possible. This video shows the test results for an artificial turf e-layer, an artificial turf system with Brock ShockPad/19, and lastly, a system with Brock PowerBase/YSR.

PROTECT THE PLAYER
Dartmouth Football has been a pioneer of safety innovation for nearly a decade. With Coach Teevens at the helm, Dartmouth football eliminated all player-on-player tackling in practice. In 2016 they continued their safety mission by installing a Brock Shock Pad System for their Artificial Turf Field.
