Over the years, we have received numerous testimonials from happy customers who are confidently wearing the PaceGuard to do the things they love, including competitive sports. Because we take our mission very seriously here at PaceGuard (we literally “Play For Life”), we wanted more. We wanted outside scientific proof to support our own rigorous testing—and now we have it. An independent study was conducted by the Sports Science Laboratory (SSL)at Washington State University which confirmed our critical durability and force claims. As is the norm in engineering testing, PaceGuard was tested to failure to see how the materials behave under extreme loading conditions.

The third PaceGuard was mounted to the steel plate with a 1” thick
foam. It was successfully impacted at four times at 30mph, four times at 40mph, four times at 50mph, and once at 60mph. It broke on the second impact at 60mph. Using a fourth PaceGuard, it was impacted once at 70mph and broke.

Following are the results:

The Sports Science Laboratory (SSL) at Washington State University specializes in the dynamics of bat and ball collisions. Their research helps regulating agencies better understand equipment performance through experimental testing and numeric models. The lab is certified with the ASA and the NCAA and contracts with bat and ball manufacturers to verify compliance and evaluate prototype products. In the fall of 2014, a dynamic impact test was selected to characterize the PaceGuard protector by projecting baseballs at various inbound speeds (30, 40, 50, 60 and 70mph) at the PaceGuard while mounted to a steel rigid wall (an extreme condition).

Other materials, such as rubber and foam, were inserted between the PaceGuard and the wall to better characterize the response of the PaceGuard. (Note: the impact materials were not selected to be biofidelic or resemble any part of the human body.)The setup PaceGuard was mounted directly to the steel plate and was impacted at 60mph two times. On the second shot, the setup PaceGuard cracked. The second PaceGuard was mounted to the steel plate with a 1/2” thick piece of rubber between the guard and the plate. It was successfully impacted nine times at 30mph and six times at 40mph. It cracked on the seventh hit at 40 mph

The third PaceGuard was mounted to the steel plate with a 1” thick
foam. It was successfully impacted at four times at 30mph, four times at 40mph, four times at 50mph, and once at 60mph. It broke on the second impact at 60mph. Using a fourth PaceGuard, it was impacted once at 70mph and broke.

Results showed that the PaceGuard was an effective way of decreasing peak force from a ball impact.
As inbound speed increased, the PaceGuard force dissipation percentage increased. In fact, the largest peak force reduction of 70% was observed at 60mph when testing 1” foam. We were also pleased to see that the PaceGuard was capable of surviving over 12 shots at low speed (30-50mph) because this is more typical of the speeds recreational players will face in game conditions.

We didn’t stop there.

A force plate study of the PaceGuard was conducted by the Athletic Training Department at Montclair State University in New Jersey. There was no compensation given tothe university or the researchers for the workdone. The study set outto prove whether or not the PaceGuard absorbs a significant amount of force and aimed to use as much force as a 70mph baseball would create.

The results?

In a comparison of the averages it is clear that the PaceGuard does reduce force placed on the force plate—79.763N difference. According to the write-up in the Discussion section of the final report -

“The data we analyzed reported that the PaceGuard does have the value to protect humans using this device.”

Most of the customers who purchase the PaceGuard will never face the extreme conditions we had tested. However, they can now rest assured that the PaceGuard lives up to its expectation and performs as it was designed to do.

“I am a pediatric electrophysiologist and care for many children and young adults with pacemakers. The PaceGuard may help to protect the pacemaker in the young patient from injury. It is important, however, that all patients with implantable devices carefully follow the recommendations of their electrophysiologists when making choices regarding sports participation.”
