Studies have shown that sleep affects physical performance and certain aspects of motivation in general. Even though it is well known that adolescents are generally sleep deprived, very few studies have investigated the impact of sleep on the inactivity of teens. The aim of this study was to determine the association between sleep and sport motivation in teenagers. 176 young, physically active participants (10-18y; 86 male) completed an online survey comprised of questions extracted from the Adolescents Sleep Habits Survey, the Pediatric Daytime Sleepiness Scale, the Morningness Eveningness Questionnaire, and the Sports Motivation Scale-28. The self-determination theory of motivation was used to determine the different types of motivation, from the most autonomous motivation (intrinsic motivation) to the least autonomous (extrinsic motivation-externally regulated). Amotivation represent an absence of motivation. Pearson correlations were computed between the sleep variables (sleep habits, daytime sleepiness, chronotype score) and the motivation variables (different types of motivation, and amotivation scores). Results show that amotivation is significantly associated with daytime sleepiness (r=.16, p =.03). The external regulated form of extrinsic motivation score is significantly associated with daytime sleepiness (r=.157, p=.037), chronotype score (r=-.164, p=.03), and bedtimes on weekends (r=.156, p=.042). The intrinsic motivation score is significantly associated with wake times on weekdays (r=-189, p=.012). These results suggest that eveningness, higher daytime sleepiness, and later bedtimes on weekends are associated with amotivation and external regulation of sport motivation. Research has shown that teens who present those two characteristics are more likely to drop out of sports teams or leagues. This could have important implications when addressing inactivity and sport motivation problems in adolescents. N/A

Abstract Introduction Perfectionism has been related to cognitive anxiety in sports. The bidirectional association between sleep and anxiety has also been well studied. However, the relationship between sleep habits, anxiety and perfectionism in physically active young individuals hasn’t been documented yet. This was the objective of the present study. Methods 150 young, physically active participants (10 to 18 years old; 47% boys, 51% girls) completed an online survey comprised of questions extracted from the Sport Multidimensional Perfectionism Scale-2, the Competitive State Anxiety Inventory-2R and the Adolescent Sleep Habits Survey. First, independent t-tests were conducted to compare sleep habits, personal standards (PS), perceived parental pressure (PPP) and perceived coach pressure (PCP) of more anxious (ANX) to less anxious (NOANX) participants. Then, stepwise multiple linear regression analyses were computed to examine the significant sleep habits and perfectionism variables associations with competitive cognitive anxiety. Results Results show that ANX participants have higher PS (t(148)=3.19, p=0.002), less total sleep time on weekend (TST; t(148)=-2.94, p=0.004), longer sleep onset latency (SOL) on weeknights (t(128.09)=2.28, p=0.03) and report more daytime sleepiness (t(148)=3.06, p=0.003) compared to NOANX participants. The significant sleep variables and PS collectively explained 17.7% of competitive cognitive anxiety variance (p=0.00). PS was the largest predictor (β=0.27, p=0.00), followed by daytime sleepiness (β=0.21, p=0.007), weekend TST (β=-0.17, p=0.023) and weeknight SOL (β=0.16, p=.038). Conclusion These results suggest that, even though PS is associated with cognitive anxiety, sleep seem to be an important factor to consider. Specifically, increased daytime sleepiness accompanied by difficulties falling asleep during school nights and no recovery sleep during weekends significantly contribute to competitive cognitive anxiety. These results could have important implications when addressing competitive anxiety issues in young athletes. Support N/A
