Physical Testing of Potential Football Helmet Design Enhancements
<p>Football is a much loved sport in the United States. Unfortunately, it is also hard on the players and puts them at very high risk of concussion. To combat this an inventor in Santa Barbara brought a new design to Cal Poly to be tested.</p> <p>The design was tested in small scale first in order …

Using Laboratory Impact Devices to Quantify Football Helmet Performance
When football originated in the 1800s, players wore no protective equipment. Between 1869 and 1905, there were 18 deaths and 159 serious injuries attributed to the sport. Following this, players began to wear protective equipment. The first use of a football helmet was in 1893, made of leather and …

Improving energy dissipation to lower concussion risk in football helmets
American football is notorious for being a high impact sport. There exists an especially high amount of danger to each player's brain, created in part by gameplay, but also from the helmets worn by the athletes. Football helmet pads were comparatively investigated, in order to find a better …
