Introduction
Shock absorption reduces injury risk and enhances athletic performance. This article explains the physics and engineering involved.
Key Concepts
Force Reduction (FR): Measures how much impact force the floor absorbs (DIN 18032-2 standard requires 53% minimum).
Vertical Deformation: How much the floor compresses under load (2.3–5.0 mm range).
Ball Rebound: Ensures consistent playability (≥90% of concrete rebound).
Design Features
Resilient underlayments (rubber, foam, or spring systems).
Subfloor spacing to allow controlled flex.
Conclusion
Balancing FR and deformation is critical for optimal athlete safety and performance.
