The results, obtained by The Associated Press and expected to be released later Wednesday, show that 4.3 percent of players from ages 5 to 14 were diagnosed with concussions. Thirty-four percent of the players who did report injuries complained of bruises. Ligament sprains were the second-most common injury, coming in at 16 percent.
Indianapolis-based USA Football asked another Indy-based organization, the Datalys Center, to conduct the research which evaluated more than 4,000 youth players in six states between 2012 and 2013.
Researchers found that the behavior of coaches has a direct correlation on the number of injuries, and that the youngest athletes were the least likely to be injured.
