By-products included determining incidence estimates of football-related brain injuries characterizing their cognitive effects identifying projected recovery curves distinguishing risk factors for injury and examining the long-term effects of multiple MTBIs. Unlike other areas of research research that uses athletes as participants has the advantage of a low incidence of complicating factors associated with cognitive decline such as poor health advanced age and substance abuse Ruchinskas et al. 1997 . Furthermore issues of motivation or effort are uncommon with athletes insofar as there is less risk of secondary gain as can be seen in litigation contexts. Athletes are usually highly motivated for recovery and return to play in fact they may hide deficits to avoid benching. In contrast to prior methods of research this study verified the presence and course of recovery of significant acute deficits in healthy individuals with appropriate motivation and effort. Athletes demonstrated mild neurocognitive deficits and a 5-10 day natural recovery curve when controlling for practice effects after very mild brain injuries. Although primarily clinically motivated this study provided the foundations for the study of the neurocognition of sports-related MTBIs which are more broadly termed concussions in the sports arena.
