ProTech proves effective in Penn State University Study on Football Head Safety

Philadelphia, PA (February 1, 2018)

Defend Your Head, the sports safety company based in Chester Springs, Pa., is proud to announce promising results of an independent study recently released by Penn State University centered on football related head injuries. The three year study indicates that ProTech, the exclusive soft shell helmet technology developed by DYH, was a primary factor in reducing traumatic head impacts by over 70% to the Nittany Lion players tested.

The results can be seen here in a video summarizing the independent study.

The PSU research team combined the ProTech soft shell technology with special helmet sensors to monitor collision impact forces and to collect valuable data from every practice and game day. Sensors in the helmets measured impacts of significant G-forces in real time, as well as rotational aspects of each impact and their location on the helmet.

Data analysis revealed a dramatic decrease in higher intensity sub-maximal impacts.








In 2015, before players were fitted with ProTech, linemen averaged 101.8 hits greater than 25Gs per player per week and 3 hits greater than 80Gs per player per week. In 2017, after players were fitted with ProTech, data showed an average of just 20.41 hits over 25Gs per player per week and 0.83 average weekly hits over 80Gs – a dramatic 72%+ reduction per player, per week in higher intensity impacts to the head.

“ProTech is changing the conversation around football and safety,” stated Defend Your Head Founder and former NFL football player John Roman adding, “It’s our goal to make football a safer sport for players at all levels.” Glenn Tilley, DYH’s Executive Chairman and CEO observed, “No other add-on safety technology company has subjected itself to this level of independent testing rigor. And no other company now has this authentic, independent data from actual on-field collisions that supports its technology in improving player safety. The recent Penn State Study underscores this performance representation. With the responsible and appropriate concern by parents to improve player safety, we believe it is time parents know solutions exists and ProTech is one of them.”
