“…Insufficient sleep has been shown to cause metabolic deficiencies [1,2], reduce muscle strength [3], shorten time to exhaustion during exercise [4], alter perceived exertion during exercise [5,6], and increase lapses of attention and reaction times [7,8]. All these effects can be detrimental to athletic performance and underline the importance of elite athletes obtaining sufficient sleep.…”

Sleep Quality and Chronotype Differences between Elite Athletes and Non-Athlete Controls

2018

Previous research has found that elite athletes have insufficient sleep, yet the specific kinds of sleep disturbances occurring as compared to a control group are limited. Here we compare the subjective sleep quality and chronotype of elite athletes to a control group of non-athlete good sleepers. Sixty-three winter Canadian National Team athletes (mean age 26.0 ± 0.0; 32% females) completed the Pittsburgh Sleep Quality Index (PSQI) and the Athlete Morningness Eveningness Scale. They were compared to 83 healthy, non-athlete, good-sleeper controls (aged 27.3 ± 3.7; 51% females) who completed the PSQI and the Composite Scale of Morningness. The elite athletes reported poorer sleep quality (PSQI global score 5.0 ± 2.6) relative to the controls (PSQI global score 2.6 ± 1.3), despite there being no group difference in self-reported sleep duration (athletes 8.1 ± 1.0 h; controls 8.0 ± 0.7 h). Further, athletes' chronotype distribution showed a greater skew toward morningness, despite there being no group differences in self-reported usual bedtime and wake time. These results suggest that a misalignment of sleep times with circadian preference could contribute to poorer sleep quality in elite athletes.

“…First, sub-optimal sleep is associated with increased reaction times; 30,32,39 attentional lapses; 29,31 degraded visual tracking; 31,32 reduced postural control and strength; 29,33,40,41 impaired emotional recognition, responsiveness, and control 34 ; and increased impulsivity and risky behavior. [35][36][37] Second, the cardiovascular, 38,39 endurance, 38 strength, 40,41 and accuracy 31,32 components of sport performance are reduced or impaired under inadequate or low quality sleeping conditions as well as daytime sleepiness. Consequently, individuals who experience poor sleep may be more likely to have degraded overall physical sport performance as well as brief lapses in attention to and poor visual tracking of in-game activities.…”

“…Chronic under-sleeping, sleep restriction, and sleep deprivation are associated with, and can result in, mental fatigue; 29,30 attentional lapses; 30,31 increased reaction time; 29,32 impaired predictive visual tracking; 31,32 reduced postural and dynamic motor control; 29,33 degraded intra-and inter-personal emotion regulation, perception, and responsiveness 34 ; and increased impulsivity and risk-taking behavior. [35][36][37] Furthermore, sport performance indices -including cardiovascular, 38,39 endurance, 38 strength, 40,41 and accuracy 31,32 outcomes -are reduced or impaired under inadequate or low quality sleeping conditions as well as daytime sleepiness or fatigue. Thus, individuals with habitually poor sleep may be more likely to have degraded overall sport performance, take more on-field risks, make poorer in-the-moment decisions, have less body control to appropriately act and react to cues, as well as experience brief lapses in attention to, and poor visual tracking of, in-game activities.…”

Insomnia and daytime sleepiness: risk factors for sports-related concussion

et al. 2019

Objective/Background: Poor quality and inadequate sleep are associated with impaired cognitive, motor, and behavioral components of sport performance and increased injury risk. While prior work identifies sports-related concussions as predisposing factors for poor sleep, the role of sleep as a sports-related concussion risk factor is unknown. The purpose of this study was to quantify the effect of poor sleep quality and insomnia symptoms on future sports-related concussion risk. Patients/Methods: 190 NCAA Division-1 athletes completed a survey battery, including the Insomnia Sleep Index (ISI) and National Health and Nutrition Examination Survey (NHANES) Sleep module. Univariate risk ratios for future sports-related concussions were computed with ISI and NHANES sleepiness scores as independent predictors. An additional multiple logistic regression model including sport, sports-related concussion history, and significant univariate predictors jointly assessed the odds of sustaining a concussion. Results: Clinically moderate-to-severe insomnia severity (RR = 3.13, 95% CI: 1.320-7.424, p = 0.015) and excessive daytime sleepiness two or more times per month (RR = 2.856, 95% CI: 0.681-11.977, p = 0.037) increased concussion risk. These variables remained significant and comparable in magnitude in a multivariate model adjusted for sport participation. Conclusion: Insomnia and daytime sleepiness are independently associated with increased sports-related concussion risk. More completely identifying bidirectional relationships between concussions and sleep requires further research. Clinicians and athletes should be cognizant of this relationship and take proactive measures-including assessing and treating sleepdisordered breathing, limiting insomnia risk factors, improving sleep hygiene, and developing daytime sleepiness management strategies-to reduce sports-related concussion risk and support overall athletic performance.

“…Los estudios que han examinado, los efectos de la restricción de sueño sobre la fuerza son mixtos (Simpson et al, 2017). Un estudio publicado recientemente mostró como un sueño inadecuado puede afectar a la fuerza muscular máxima en movimientos poliarticulares cuando se realiza sin intervenciones específicas diseñadas para aumentar la motivación (Knowles, Drinkwater, Urwin, Lamon, & Aisbett, 2018). Además, el deportista durante la competición, requiere de una óptima función neurocognitiva.…”

El sueño es un determinante fundamental en el rendimiento y la salud del deportista. En la actualidad algunos expertos la definen como la mejor estrategia de recuperación debido a sus efectos fisiológicos y restaurativos. Los deportistas deben ser alentados a dormir más horas que la población general, debido a las demandas de recuperación impuestas por el ejercicio. La presente revisión teórica busca esclarecer los factores que afectan al sueño, los efectos de éste sobre el rendimiento deportivo y la salud, así como explicar las estrategias más determinantes para mejorar la cantidad y calidad del sueño del deportista. Para ello es importante tener en cuenta los horarios de los eventos deportivos, el estrés psicosocial del deportista, el uso de dispositivos electrónicos, los viajes, el uso de sustancias estimulantes como la cafeína o la ingesta de alcohol, entre otros. Diferentes estrategias como la extensión del sueño, las siestas, estrategias de higiene del sueño y nutricionales deben ser consideradas en la mejora del sueño del deportista.
