84 Trajectories of hippocampal microstructure following sport-related concussion and subconcussive exposure in football players

R=0.009, p=0.541) nor with peak running velocity reached before HAE (R=4e-04, p=0.896).Conclusion This demonstrates a possible direct relationship between HAE starting at 20 g and disturbed cardiac response.Given the repetitive nature of subconcussive hits beyond this !20g threshold, there is an urgent need to investigate whether or how altered heart rate kinetics could influence severity of head injury in contact sports.
