Sub-Concussive Hits
CTE: Chronic Traumatic Encephalopathy
11. CONCUSSION FACTS
Concussion: By the Numbers
•CDC estimates reveal that 1.6 million to 3.8 million concussions occur each year
•5-10% of athletes will experience a concussion in any given sport season
•Fewer than 10% of sport related concussions involve a Loss of Consciousness (e.g., blacking
out, seeing stars, etc.)
•Football is the most common sport with concussion risk for males (75% chance for concussion)
•Soccer is the most common sport with concussion risk for females (50% chance for
concussion)
•78% of concussions occur during games (as opposed to practices)
•Some studies suggest that females are twice as likely to sustain a concussion as males
•Headache (85%) and Dizziness (70-80%) are most commonly reported symptoms immediately
following concussions for injured athletes
•Estimated 47% of athletes do not report feeling any symptoms after a concussive blow
•A professional football player will receive an estimated 900 to 1500 blows to the head during a
season
•Impact speed of a professional boxers punch: 20mph
•Impact speed of a football player tackling a stationary player: 25mph
•Impact speed of a soccer ball being headed by a player: 70mph
