Mindoo | Key Performance Analysis: How Vertical Deformation, Energy Return, and Ball Bounce Define Game Quality

The true value of professional sports wood flooring is hidden in three technical metrics that determine athletic fluidity and fair play. Mindoo dives into Vertical Deformation, Energy Return, and Ball Bounce, explaining how they collectively meet the highest FIBA certification standards for your venue.

When evaluating a sports wood floor, most attention focuses on Shock Absorption (SA), the foundation of athlete safety. However, a professional floor that genuinely enhances athletic performance is supported by three equally critical metrics: Vertical Deformation (VD), Energy Return (ER), and Ball Bounce.

Mindoo understands the importance of these indicators for both athlete performance and equitable competition. This article will detail how these three crucial data points work together to ensure your venue complies with the stringent requirements set by FIBA.

Vertical Deformation (VD) – The Guarantee of Foot Stability

Vertical Deformation measures the downward distance a floor displaces when subjected to an athlete’s weight or impact.

1. International Standard and Safe Range

According to the European Standard EN 14904, the Vertical Deformation for professional sports flooring must be controlled within:

Vertical Deformation (VD) Range:2.3mm ~ 5.0mm

• Below 2.3 mm: The floor is too stiff, offering insufficient cushioning, which increases athlete fatigue.
• Above 5.0 mm: The floor deformation is excessive, which can make athletes feel like they are "stepping into a hole." This severely compromises foot stability and force efficiency, especially during quick starts or stops.

2. Impact on Athletic Fluidity

A Mindoo system with optimal Vertical Deformation provides adequate "give" (absorbing impact) while recovering quickly to prevent an unsettling feeling. This is crucial for a basketball player’s jump shot stability and a volleyball player’s take-off power.

Energy Return (ER) – The Secret to Enhanced Jump Performance

Energy Return measures the efficiency with which the floor returns stored energy to the athlete after deformation.

1. The Balance with Shock Absorption

Many assume high Shock Absorption (high cushioning) inevitably leads to low Energy Return, but professional flooring must break this trade-off:

• Mindoo’s Solution: Through optimized resilient structure design (such as the Mindoo multi-layer sleeper system), our floors absorb impact to protect joints while simultaneously returning energy to the athlete with higher efficiency.
• Direct Effect: This reduces the energy an athlete expends during a jump, making them feel "lighter" during runs and jumps, significantly boosting endurance and athletic performance.

2. Reducing Fatigue, Boosting Performance

High Energy Return is not just about "jumping higher," but more importantly, "jumping longer." It mitigates fatigue accumulation during extended gameplay, ensuring athletes maintain high-level explosive power in the final stages of a match.

Ball Bounce – The Iron Rule of Fair Competition

Ball Bounce is a mandatory requirement for fairness stipulated by FIBA and all professional basketball competitions.

1. Mandatory International Requirements

The Ball Bounce for professional sports wood flooring (using a standard basketball) must achieve a rebound height of:

Ball Bounce: ≥90% of the bounce on concrete

• Cornerstone of FIBA Certification: Mindoo’s FIBA certification ensures that our flooring system maintains a high and consistent rebound performance under varying conditions of temperature and humidity.
• Data Uniformity: Certification requires manufacturers to ensure high consistency in ball bounce across the entire court, eliminating the presence of "dead spots."

2. Decisive Impact on Game Quality

High and consistent Ball Bounce is fundamental to maintaining game quality:

• Coach Trust: Coaches and players can trust the floor's rebound performance to execute precise passing and dribbling strategies.
• Spectator Experience: Fluid, accurate dribbling and passing provide a more exciting, higher-level viewing experience for the audience.
