A new study says reducing full contact during Wisconsin high school football practices has led to a 57 percent decline in the rate of concussions, according to the University of Wisconsin School of Medicine and Public Health.
The study examined concussion reports in the WIAA before and after a 2014 league rule that put a weekly limit on full contact activities. Before the rule was implemented, there were 86 concussions per 1,000 athletic exposures from 2012-13. After the rule was put in place in 2014, that number went down to 15 concussions per 1,000 exposures.
The WIAA rule currently bans full contact during the first week of preseason, and puts roughly an hour limit on full contact drills every week after during the season.
