‘Shocking’ findings
In an accompanying editorial, Christopher J. Nowinski, PhD, of the Concussion Legacy Foundation, Boston, and Robert C. Cantu, MD, department of neurosurgery, Emerson Hospital, Concord, Massachusetts, said the findings could have significant policy implications and offer a valuable expansion of prior research.
“From 2005 to 2010, studies on college football revealed that about two-thirds of head impacts occurred in practice,” they noted. “We cited this data in 2010 when we proposed to the NFL Players Association that the most effective way to reduce the risks of negative neurological outcomes was to reduce hitting in practice. They agreed, and in 2011 collectively bargained for severe contact limits in practice, with 14 full-contact practices allowed during the 17-week season. Since that rule was implemented, only 18% of NFL concussions have occurred in practice.”
“Against this backdrop, the results of the study by McCrea et al. are shocking,” they added. “It reveals that college football players still experience 72% of their concussions and 67% of their total head injury exposure in practice.”
Even more shocking, noted Dr. Nowinski and Dr. Cantu, is that these numbers are almost certainly an underestimate of the dangers of practice.
“As a former college football player and a former team physician, respectively, we find this situation inexcusable. Concussions in games are inevitable, but concussions in practice are preventable,” they wrote.
“Laudably,” they added “the investigators call on the NCAA and football conferences to explore policy and rule changes to reduce concussion incidence and HIE and to create robust educational offerings to encourage change from coaches and college administrators.”
