Athletes Often Suffer A Concussion – Part 2 of 3
And “We did see significant differences in concussion rates with elevation changes,” study co-author Dawn Comstock, an partner professor of epidemiology at the University of Colorado School of Public Health, said in a UC Denver news release. “This could mean that kids in Colorado are less able to sustain a concussion playing sports than kids in Florida”. The reasons for the lower concussion rates at higher altitudes are unclear, but Comstock and colleagues offered one possible explanation.
They distinguished that sports-related concussions occur when the brain collides with the skull when a player is hit in the head. But as altitude increases, blood vessels in the brain undergo mild swelling. This swelling, along with other changes, causes the thought to fit more snugly in the skull. As a result, the brain does not move around as violently when the head is struck.
