WHAT IS ROTATIONAL RESISTANCE?
- Rotational resistance, also known as rotational friction or traction, refers to the resistance offered by a surface when an object rotates or pivots on it. It's a measure of how much force is needed to initiate and maintain rotational movement on that surface.
- Rotational resistance is a key factor in assessing the safety and performance of sports surfaces like artificial turf or natural grass.
- Too much rotational resistance can lead to injuries as the foot gets stuck and the joint twists excessively. Too little resistance can cause slipping.
- A good surface should allow for controlled movements like pivoting and cutting without causing the athlete to slip or experience excessive joint stress.
- Test results should always be between 25 and 50 n-m
- Applicable standards EN 15301, EN 15330, and FIFA 06
WHY IS IT IMPORTANT TO PERFORM A ROTATIONAL RESISTANCE TEST ON YOUR NATURAL OR SYNTHETIC SPORTS FIELD?
1. Demonstrates a proactive approach to safety.
2. Potentially help protect field owners from lawsuits.
