G-Max Testing in New England
When a player falls on a turf field, the impact is either absorbed by the surface of the synthetic field or by the player’s body. As a result, the harder the surface, the more opportunity the player has of absorbing the fall, resulting in an injury. When most of the impact is taken by the player, the injury can result in a concussion.
We use g-max testing to determine the rate upon which the player’s head would make contact with the turf surface. When g-max test results are higher, this results in the turf surface having poorer shock-attenuation. If a field does not meet the requirements of the ASTM, less than 200g, the turf is considered unsafe for players.
When Turf Prep installs a synthetic field, a g-max test is completed to get a base number. The following can affect your g-max values:
- Type of maintenance performed on the turf
- Materials used in the maintenance
- Location conditions
- How often the turf is used
- Construction procedures
Experts go back & forth on how often you should have your turf tested. Some suggest twice a year, while others say only once a year. Not only does annual testing keep track of any changes, but it shows parents that you are committed to their children’s safety. It is important to have your g-max testing done by a professional company. Turf Prep’s certified team meets all of the ASTM standards & criteria. After we install a synthetic field, we perform a g-max test & provide the client with the results to keep on file. As a coach, player or parent, knowing a turf has been g-max tested can put your mind at ease.
