- W2464231560 abstract "PURPOSE: Fears over the long term effects of repeated head impacts have resulted in sporting organizations to place restrictions on full contact football practice at the professional, collegiate and high school levels. Prior to the 2014 season, the Michigan State High School Athletic Association limited full contact practices to no more than two days per week. This investigation sought to evaluate head impact exposure during interscholastic football prior to and following the rule change. METHODS: As part of a larger investigation on head impact exposure and cognitive function, 41 athletes participated in the 2013 (n=26) and 2014 (n=24) seasons. Nine athletes participated in both years. Following informed consent/assent, each athlete’s helmet was fitted with a Head Impact Telemetry (HIT) System encoder to monitor head impact frequency during all games and practices. Impact exposure was evaluated by player position for each year of the study. RESULTS: In 2013, 15,398 impacts were recorded and 8,269 in 2014. In 2013, the average football athlete sustained 592+391 head impacts, compared to 345+236 in 2014. Overall, there was a 41.8% decline in head impacts between the two seasons. Quarterbacks had the largest decline (-48.1%); followed by the Linemen (-37.3%); Receivers, Corners, and Safeties (-22.8%); and Tight Ends, Running Backs, and Linebackers (-18.5%). CONCLUSIONS: This investigation demonstrated a substantial reduction in head impacts following restriction of full contact football practices that goes beyond previous estimates. How this change influences long term cognitive health is not clear, but reduced impact exposure during practice has been shown to diminish overall concussion rates. This investigation was funded by The National Institutes of Health: National Institute of Neurological Disorders and Stroke (1R15NS081691-01)" @default.
