The American Football Helmet and Concussions John Krauss

Football accounts for the most sports-related concussions in the United States. The National Operating Committee on Standards for Athletic Equipment (NOCSAE) Overview Ruling Change in 1975 prohibiting players from leading with their heads.

F = m Striking a Striking +FN F = m Struck a Struck Forces At Work SI = ∫ a(t)2.5dt * The resulting SI score has to be below 1200 in order for a helmet to pass the safety test.

Concussions * One of the dangers associated with concussions is that after receiving one, a player is more susceptible to further trauma for up to 14 days. * Tendency of concussions to show no pathological changes on standard MRI and CT scans. * After the initial trauma, there is a marked decrease in blood to the affected area of the brain. * Multiple traumatic brain injuries can lead to severe long term health effects and can become fatal * Two areas of the brain that show susceptibility to trauma are the frontal and temporal lobes.
