Conclusions : Chronic lack of sleep in adolescents is associated with greater risk of sports and musculoskeletal injuries .
Current evidence can not yet definitively determine the effect of acute lack of sleep on injury rates .
Background : Although sleep has been identified as an important modifiable risk factor for injury , the effect of decreased sleep on sports injuries in adolescents is poorly studied .
The objective of this study was to quantitatively and qualitatively review published literature to examine if a lack of sleep is associated with sports injuries in adolescents and to delineate the effects of chronic versus acute lack of sleep .
Epidemiology of sports-related concussion in seven US high school and collegiate sports
Background The epidemiology of sports-related concussion is not well-described in the literature . This paper presents a descriptive epidemiology of concussion in seven high school and collegiate sports . Methods We used the data from Concussion Prevention Initiative ( CPI ) , which enrolled 8905 athletes at 210 high schools and 26 colleges in a prospect i ve cohort study of 7 sports ( football , men ’s and women ’s soccer , men ’s and women ’s lacrosse , and men ’s and women ’s ice hockey ) between 1999 and 2001 . Injury risks and injury rates were used to characterize the incidence of concussion , and changes in symptoms over time were described . Results A total of 375 concussions were observed . The incidence of concussion was highest in football , followed by women ’s lacrosse , men ’s lacrosse , men ’s soccer , and women ’s soccer ( only 10 ice hockey teams were included , too few to quantify incidence ) . The rate of incident concussion was strongly associated with history of concussion in the previous 24 months ( rate ratio = 5.5 ; 95 % CI : 3.9 , 7.8 , for 2 or more concussions relative to no previous concussion ) . The most common symptoms at time of injury were headache ( 87 % ) , balance problems/dizziness ( 77 % ) , and feeling “ in a fog ” ( 62 % ) . Loss of consciousness and amnesia were present in relatively few cases ( 9 and 30 % ) . The most common mechanism of injury was collision with another player . Conclusions Sports-related concussions present with a diverse range of symptoms and are associated with previous concussion history
