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 .
Sleep patterns and injury occurrence in elite Australian footballers.
OBJECTIVES To examine the potential relationship between sleep duration and efficiency and injury incidence in elite Australian footballers . DESIGN Prospect i ve cohort study . METHODS Australian footballers ( n=22 ) from one AFL club were studied across the 2013 competitive season . In each week sleep duration and efficiency were recorded via actigraphy for 5 nights ( the 3 nights preceding a game , the night of the game and the night after the game ) . Injury incidence was monitored and matched with sleep data : n=9 players suffered an injury that caused them to miss a game . Sleep in the week of the injury ( T2 ) was compared to the average of the previous 2 weeks ( T1 ) . A two-way repeated measures ANOVA was used to determine any effect of sleep duration and efficiency on injury . Significance was accepted at p<0.05 . RESULTS Injury incidence was not significantly affected by sleep duration , sleep efficiency or a combination of these factors . Analysis of individual nights for T2 versus T1 also showed no differences in sleep quality or efficiency . However , a main effect for time was found for sleep duration and efficiency , with these being slightly , but significantly greater ( p<0.05 ) at T2 ( 437±61min and 82±7 % ) than T1 ( 414±64min and 79±7 % ) . CONCLUSIONS No significant effect of sleep duration and efficiency on injury occurrence was found in elite Australian footballers
