How do sports helmets protect the brain?
A helmet protects the head from injuries. It is designed as a protective gear to minimize the injury on head and brain.
-Contain a layer of crushable foam: Foam part of helmet crushes when you hit and crash a hard surface. Crash energy is controlled and head’s stopping time is extended by about six thousandths of a second (6 ms) when you hit and crash a hard surface to minimise the peak impact of the brain. Internal strains and rotational forces are reduced by crushing. To have a better result, use less dense foam because it cruseh in lesser impact. In order to avoid crushing down I harder impact, the crushable foam should be thicker.
-Smooth plastic skin: It holds helmet foam together. Smooth plastic skin works by helping helmet foam crushes and skid easily on crush surface. To skid more easily, use rounder helmets. During crash sequence, the straps keep the helmet on your head. …show more content…
-Fitting pads were neglected before this but has received more attention in 1990’s. It features a suede-covered thick cotton sweatband that wa look-and-hook mounted which was discovered by MSR in its first model. Eventhough many high tech materials now touted as features for higher priced helmets, fitting pads in helmets has not been equaled or duplicated in comfort or sweat control.
-Helmets has evolved as well. American has head size crept upward throughout the 20th century. In early years, riders with larger heads find difficulties to get size larger than 7. Bell brought out their Kinghead in 1998 made first bicycle helmet designed uniquely for riders with extra-large heads.
- Improvement that could be made is using diagnostic software and microprocessors that can relay information toa a handheld device on the sideline. By using this, it can determine how much a player suffered from serious head injury.
