2 ABSTRACT SD & athletic performance Injuries & self- evaluation Questionnaires- 4 sports Partially/fully supported

3 RESEARCH QUESTION What is the correlation between sleep deprivation and the quality of athletic performance in adolescents?

4 PURPOSE Competitive gymnast: optimal performance? School + gym = sleep deprived

5 GENERAL INFORMATION What is sleep? Sleep and daytime functioning Adolescents: 8-10 hours (NSF)

6 SLEEP DEPRIVATION (SD) Reduced or interrupted sleep Mass media and academic burdens What are the effects? Image 1

7 SLEEP AND ATHLETES Reduced quantity and quality Essential for recovery and preparation Affects important factors Image 2

8 Image 3

9 PREVIOUS STUDIES Sleep & goalkeeper (Jarraya et al.) Slow reaction time Sleep & risk of injury (Kim et al.) Impulsivity, attention, decision making

10 HYPOTHESIS Increased frequency of injuries Negative self-evaluation of performance Image 4

11 METHODS Create questionnaires Occurrence of injuries Self-evaluated performance Epworth Sleepiness Scale (ESS) Cross country, gymnastics, lacrosse, volleyball

12 METHODS (CONT.) Separate into 3 groups: Score 0-6 Score 6-12 Score12-18 ANOVA TEST & scatterplots

14 RESULTS Sleep deprivation & Injuries: ANOVA.0002 Sleep deprivation & Performance: significant

15 Cross Country and Gymnastics Processed Data Table for Sleep Deprivation and the Occurrence of Injuries Sport Avg. ESS Score Avg. # of injuries Mode Injury Type Cross Country Shin splints Gymnastics Muscle pull/ strain

16 Lacrosse and Volleyball Processed Data Table for Sleep Deprivation and Self-Evaluated Performance Sport Avg. ESS Score Avg. performance score Lowest avg. score Highest avg. score JV Lacrosse I make sleep my top priority The amount of sleep I get can influence my performance the following day Varsity Lacrosse I make sleep my top priority The amount of sleep I get can influence my performance the following day Volleyball I make sleep my top priority The amount of sleep I get can influence my performance the following day

17 Number of Injuries Epworth Sleepiness Scale Score and the Number of Injuries in Cross Country Runners and Competitive Gymnasts Epworth Sleepiness Scale y = x R² = Cross country runners and competitive gymnasts

18 Self Evaluated Performance Score Epworth Sleepiness Scale Score and Self Evaluated Performance Score in Volleyball and Lacrosse Players Epworth Sleepiness Scale Score y = x R² = Volleyball and Lacrosse players

19 HYPOTHESIS Increased frequency of injuries Negative self-evaluation of performance

20 HYPOTHESIS SUPPORT SD & Injuries: partially supported R-squared: not significant ANOVA: significant SD & Performance: supported

21 MAJOR FINDINGS More SD and injuries in gymnasts Varsity more significant than JV Highest avg. score vs. lowest

22 EXPLANATIONS Gymnastics intensity & hours Varsity reaction time & age Effects recognized/ sleep sacrificed

23 IMPROVEMENTS Larger sample Sports Ages Limiting factor: surveys

24 FUTURE RESEARCH Sleep deprivation and injuries Sleep deprivation and academics Sleep deprivation and nutrition Nutrition and athletic performance

25 IMPLICATIONS Athletes: educated for optimal performance Importance of sleep Image 5

26 ADDING TO THE FIELD Overall effect on athletic performance More than specific factor General conclusion

27 INTERNATIONAL RELEVANCE Essential to all Occurs everywhere Universal & prevalent issue Image 6
