The Ivy League will announce on Wednesday that, in an effort to minimize head injuries among its football players, it will sharply reduce the number of allowable full-contact practices teams can hold.
The changes, to be implemented this season, go well beyond the rules set by the N.C.A.A. and are believed to be more stringent than those of any other conference. The league will also review the rules governing men’s and women’s hockey, lacrosse and soccer to determine if there are ways to reduce hits to the head and concussions in those sports.
The new rules will be introduced as a growing amount of research suggests that limiting full-contact practices may be among the most practical ways of reducing brain trauma among football players. According to a study of three Division I college teams published last year in the Journal of Athletic Training, college players sustain more total hits to the head in practices than in games.
