As an athletic director, you're responsible for protecting student-athletes while managing tight budgets and complex regulations. GMAX testing might seem like just another expense, but it's actually one of your most important tools for preventing catastrophic injuries and protecting your program from liability.
This comprehensive guide will help you understand everything you need to know about GMAX testing, from basic requirements to budgeting and scheduling.
What is GMAX Testing?
GMAX (Gravity Maximum) testing measures the maximum deceleration experienced when a standard mass impacts an artificial turf surface. Think of it as measuring how "hard" your field hits back when a player lands on it.
The Science Behind GMAX
The test uses a specialized missile that simulates a human head impact. The resulting measurement indicates the potential for head injuries - the higher the GMAX reading, the greater the risk.
GMAX Standards
- Below 165g: Optimal safety range
- 165-200g: Acceptable but requires monitoring
- Above 200g: Unsafe - immediate action required
- Above 325g: Extremely dangerous - field should be closed
Legal and Insurance Requirements
When GMAX Testing is Required
- Many insurance policies require annual testing
- State athletic associations may mandate testing
- NCAA requires testing for championship events
- Professional leagues have strict testing protocols
- Recommended after significant field repairs
Liability Protection
Critical: Having current GMAX test results can be crucial in defending against injury lawsuits. Courts increasingly expect athletic programs to demonstrate proactive safety measures.
Documentation Requirements
Proper GMAX testing provides legally defensible documentation that shows:
- You took reasonable steps to ensure player safety
- Your field met industry safety standards
- You followed professional maintenance protocols
- You have objective data to support safety claims

Timing and Scheduling
Optimal Testing Schedule
- Pre-Season: 4-6 weeks before first game
- Mid-Season: After heavy usage periods
- Post-Repair: Within 30 days of major maintenance
- Incident-Triggered: After any significant injury
Seasonal Considerations
Summer (June-August)
Best for: Major maintenance and testing
Fields are typically unused, allowing comprehensive evaluation
Fall (September-November)
Considerations: Peak usage season
Monitor carefully, test if readings were borderline in summer
Winter (December-February)
Planning phase: Schedule for spring
Weather may affect testing accuracy in some regions
Spring (March-May)
Pre-season prep: Final testing before sports seasons
Address any issues before fall activities begin
