MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Very limited data has been collected in children while they are playing contact sports to study the relationship between repetitive head impacts and neurocognitive outcomes. We previously published a 1-year analysis of youth tackle football players and found no association between the number or severity of head impacts and performance on neurocognitive testing before to after the football season. We are now reporting the results from the 2nd year of our study, tracking children through two seasons of football participation.
We measured head impacts using helmet sensors during the 2016 and 2017 football seasons. In the total group of 166 players age 9-18, one outcome measure (processing speed), out of the 23 outcome measures studied, declined over time. However, several other measures that also assessed processing speed did not decline. Neither the total burden of head impacts nor the intensity of individual impacts were associated with changes in testing performance over the course of the two seasons.
