Young football players are more likely to experience a brain-jarring hit to the head if they’re part of a team’s running and passing game or a fast-moving defender, a small study found.
High-magnitude head impacts most often involve positions such as quarterback, running back and linebacker as those players sprint across an open field, Virginia Tech researchers concluded after watching a season of youth football in Blacksburg, Va.
These players experienced nearly twice the number of severe head hits as linemen did, the study reported.
“Players who are able to get up to speed prior to impact, players who are off the line of scrimmage, those players are more likely to experience a high-magnitude head impact,” said lead researcher Eamon Campolettano. He is a graduate research assistant at the university’s department of biomedical engineering and mechanics.
Campolettano and his colleagues classified high-magnitude impacts as those amounting to greater than 40 times the force of gravity—or 40g.
About 8 percent of the head impacts that occurred during youth play and practice were hard enough to be classified as high-magnitude, the researchers found.
