Results: There were a total of 188 injuries in 121 wrestlers with overall injury rate of 5.13/1,000 athlete exposure
. 35 wrestlers sustained 71 knee injuries (71/188; 37.77%).
This study looked at the incidence of concussion in all levels of collegiate athletes (divisions I-III, including scholarship and nonscholarship athletes) and determined that linebackers (a defensive player who delivers violent, high-impact tackles to stop the advancing offensive player) experienced the highest rate of concussions at 0.99 concussions per athlete exposure
, whereas wide receivers (an offensive player responsible for catching passes, typically does not involve significant contact) exhibited the lowest incidence at 0.53 concussions per exposure.
An athlete exposure
was defined as one athlete participating in one practice or competition during which the athlete was exposed to the possibility of athletic injury.
Their analysis found that rugby had the highest concussion rates in children - 4.18 concussions per 1,000 athlete exposures
- compared to 1.2 for ice hockey and 0.53 for American football.
The research found rugby had the highest concussion rates in children - 4.18 per 1,000 athlete exposures
compared to 1.20 and 0.53 for ice hockey and American football respectively.

The outcome measures utilized in this study include number of athletes, number of reported injuries, number of athlete exposures
, age of athlete, injury rates, TKD experience level (black belt degree, also known as DAN), location of body part injured, injury type, injury mechanism, injury severity, and the point in time when the injury occurred (training or in competition).
Statistics are tracked in terms of athlete exposures
- the number of games or practices multiplied by the number of athletes participating.
Overall, the rate increased from .23 to .51 concussions per 1,000 athlete exposures
. An exposure is defined as one athlete participating in one competition or practice.
Rates per 100,000 athlete exposures
were calculated based on the actual number of time-loss heat illnesses reported by the schools.
1,000 game exposures, and 4 for girls and 5 for boys per 1,000 athlete exposures
. When data from practices alone were used, however, the injury rate ratio (the female rate divided by the male rate) suggested that girls are three times more likely than boys to injure a knee during practice and twice as likely to injure an ankle.
Prior studies have reported injury rates ranging from 0.4/1000 athlete exposures
to 25/1000 athlete exposures
to 12.7/100 athlete exposures
, depending on the definition of injury and experience level of fighters .
