GIRLS ARE MORE SUSCEPTIBLE TO WHIPLASH
"Girls as a group have far weaker necks. That same force delivered to a girl's head spins it much more because of the weak neck. Girls don't produce enough testosterone to build big, bulging necks, but they're going to be stronger which will help protect them."
Dr Robert Cantu M.D., Boston University School of Medicine
BIGGEST THREAT: ROTATIONAL ACCELERATION
"As the head rocks back and forth, it's also twisting a little on the brain stem, and it's those accelerative and rotational forces as the brain is impacting inside the skull that are really what's causing these concussions. A stronger neck means you're reducing those accelerative and rotational forces."
Dr Dawn Comstock, Colorado School of Public Health
