Revolutionizing Gymnastics Safety: Highlighting the Limitations of Current Testing Methods

"The future development of gymnastics is a complex and complicated process. Part of it involves new technique for elements and creation of new skills. But human abilities are limited, and therefore, we need new, modern gymnastics apparatus, which would help gymnasts perform new skills and at the same time provide safety.” - Nellie Kim , VP Fédération Internationale de Gymnastique (FIG)

Dear Gym Owners, Coaches and Athletes,

I hope this message finds you well. I wanted to bring to your attention some crucial insights regarding the safety testing protocols for gymnastics floor apparatus, particularly in light of recent advancements in safety technology.

As you may know, traditional testing methods, such as the drop tests conducted by Fédération Internationale de Gymnastique (FIG) , have been the standard for assessing the safety of gymnastics equipment. When, in fact, they are not a measure of safety, at all. They only confirm that the spring rate is in a certain range. Therefore, these tests have significant limitations, particularly when it comes to evaluating the performance and safety features of innovative technologies like the Weller Floor.


FIG Floor Apparatus Test?conducted?at AAI's?Jefferson, Iowa plant?over 3 days in November 2008

“It consists of a 10kg mass (and we repeated with 20kg) configured to drop at various heights.? The impactor is instrumented with an accelerometer and LVDT (displacement transducer).? We can either directly measure or calculate: velocity, acceleration, force, impact time, deflection, and rebound. ?A good indicator of your spring being easier on an athlete would be if the impact time is longer than ours. ?Therefore the peak force transmitted to the athlete would be decreased.? The only criteria I would set today would be if your impact time is shorter than ours than we may consider it a failure.? The displacement data could be used in the future to prove/deny any claims of a closer matched response to the athlete but at this time I do not have any data on the athlete side either.” – Todd Reindors, American Athletic, Inc Engineering Manager

Data showed Weller Spring Floor meets FIG requirement, that impact time is longer, and post impact floor vibration is reduced significantly in intensity and duration. The board, foam and carpet were constant. “x” marks on carpet (above) indicate 9 positions on the board where 10kg and 20kg weight was dropped from various heights.


Key Findings from Our Research:

  • Superior Shock Absorption: Weller Spring Floor demonstrates a slightly lower dominant frequency (~8 Hz) compared to traditional cylindrical springs and foam blocks (~9 Hz), indicating better shock absorption capabilities.
  • Enhanced Energy Transfer: In terms of impulse, which measures the total force over time, Weller showed lower values. This means Weller provides better energy dissipation, crucial for both performance and injury prevention.
  • Superior Rate of Force Development: Weller Spring Floor produces a higher rate of force development on the downward motion and a lower rate of force development on the upward motion. This translates to safer landings, more power on takeoff, greater control over movements, and more time in the air.


FIG Floor?Apparatus Test Doesn't Measure Safety

Let's do a thought experiment. Imagine testing a new iPhone using criteria designed for an old rotary phone. Both devices pass the test, but it doesn't account for the iPhone's advanced features like internet capabilities. Similarly, traditional gymnastics floor tests may not detect the safety and performance benefits of our innovative technology.


While traditional testing methods may not fully capture the benefits of our technology, we believe it is essential to highlight these advancements and their potential impact on gymnastics safety. By raising awareness of the limitations of current testing protocols and advocating for updated regulations that reflect the latest advancements in safety technology, we can work towards a safer and more equitable environment for gymnasts worldwide.

“Nothing is more important than the safety of athletes. As a company, we are committed to advancing the technology of gymnastics equipment to make the sport safer and more enjoyable for all. We are proud to introduce our latest innovation, variable pitch engineering, and are excited to work with industry leaders to prioritize the safety of gymnasts around the world.” Scott Weller, Founder and Inventor, King Bars Sports, LLC.

I would be happy to provide further information or demonstrations of our technology to support these efforts. Thank you for your attention to this matter, and I look forward to any opportunities to collaborate on improving gymnastics safety standards.

Play Safe!

Why Gymnasts LOVE Weller Spring Floor

Most Frequently Asked Question

Q: Is it difficult for gymnasts to train on Weller Floor and compete on other floors?

A: Gymnasts LOVE training on Weller Floor because the forgiving nature of the floor allows more training with fewer injuries. Legs, knees, ankles, and Achilles feel better so having fresh legs is a competitive advantage. The loading is identical to other floors so it’s just not an issue, otherwise.


?? EASIER ON THE ATHLETE? Weller Floor Features Patented Variable Pitch Engineering.

? What is Variable Pitch Engineering? It works by altering the pitch of the springs within the floor, resulting in a frequency response that reduces the stress on the athlete’s body during certain movements, i.e., dorsiflexion.

?? An Analogy: This innovation has been likened to airbags in automobiles, which increase the impact time over which the body is stopped, reducing the force and risk of injury.
