“…Concomitantly, the common scheduling of training in the morning may further impair the time available for sleep 14 . A wide array of interventions can compensate in these situations, for example, sleep hygiene education 11 and sleep extension have been explored with positive findings in some studies 15 , 16 . However, for appropriate interventions to be implemented, precise tools are required to first obtain information on the athlete’s current sleep habits and behaviors.…”

Introduction:Considering the specificity of the sporting context and the influence of sleep on athletic performance, the "athlete sleep behavior questionnare" (ASBQ) was developed to evaluate sleep behavior in English-speaking athletes. Objective: The aim of this study was to perform a cross-cultural adaptation and validation of the ASBQ in Brazilian athletes. Methods: The cross-cultural adaptation was processed by procedures of translation and back-translation. Content validity was performed by 9 experts, calculating the coefficient of content validity for the equivalence of the individual items (Cvci) and the total global score (Cvct), in addition we conducted a pilot study using the translated version of the questionnaire. The next phase of the study included 52 athletes completing the translated ASBQ. The reliability of the questionnaire was assessed by the intraclass correlation coefficient (ICC), standard error of measurement (SEM) and by Cronbach's alpha (α). Results: The ASBQ passed the process of cross-cultural adaptation, obtaining the Brazilian Version of the ASBQ (ASBQ-BR), and with acceptable values of Cvci (0.89-1.00) and Cvct (0.96). Additionally, the ASBQ-BR showed acceptable values of reliability (ICC=0.857; Cronbach's α=0.78) and a SEM of 3.05 AU. Conclusion: The ASBQ was translated to a newly developed ASBQ-BR, resulting in acceptable values for content validity and reliability. The ASBQ-BR provides a valuable tool for monitoring sleep behaviors in Brazilian athletes.

“…Elite athletes’ sleep may be more disturbed than normal due to reasons such as jetlag, altitude, early morning training, increases in training load and traveling to sport meetings which might involve getting up early in the morning or retiring late at night [ 55 ]. In addition, a recent systematic review focused on the effect of sleep extension in athletes and concluded that the most important factor is athlete’s normal sleep pattern and whether he/she is getting adequate sleep [ 56 ].…”

The effect of 40-min nap (NAP) opportunity on psycho-physiological outcomes and technical performance during small-sided basketball game (SSG) was examined in ten professional basketball players. Nocturnal sleep and naps were monitored by actigraphic recording and sleep diaries. Nocturnal total sleep time (TST), time in bed (TIB), sleep efficiency (SE), sleep onset latency (SOL) and wake after sleep onset (WASO) were analyzed. Subjective sleep quality was assessed with visual analogue scale (VAS). Profile of mood state (POMS) and simple reaction time (SRT) were measured before and after Nap and no-nap (CON) conditions. During both test sessions, participants played 10-min SSG. Technical and tactical performances were assessed using Team Sport Assessment Procedure. Volume of play (VP), attack with ball (AB), efficiency index (EI) and performance score (PS) were determined. Heart rate (HR) was measured during SSG, and rating of perceive excretion (RPE) after. Lower HR (p ≤ 0.03, d ≥ 0.78) and RPE (p = 0.007, d = 1.11) were obtained in NAP compared to CON. There was no significant difference in TIB, TST, SE, WASO and VAS between CON and NAP conditions. AB, EI and PS were higher in NAP compared to CON (0.0002 ≤ p ≤ 0.001, 1.3 ≤ d ≤ 1.8). A significant reduction was observed in POMS’ fatigue (p = 0.005, d = -1.16, Δ = -53.6%), anxiety (p = 0.02, d = -0.9, Δ = -32.1%), anger (p = 0.01, d = -0.94, Δ = -30.3%), and an improvement in vigor (p = 0.01, d = 0.99, Δ = + 23.8%); which may reflect better readiness after nap and more concentration to start a game-situation. In summary, NAP reduced fatigue, anger, anxiety and enhanced vigor, allowing better technical and tactical performances during basketball SSG.

“…It is generally accepted among the sport science community that many elite athletes accrue insufficient amounts of sleep 4 and the quality of their sleep is suboptimal. 5 Much of the available work prioritizes evidence on differences in mean levels of sleep metrics between individuals (interindividual variability) for interventions or strategies, [6][7][8] with little consideration of intraindividual variability for optimizing sleep health. This gap in knowledge limits our potential to generate innovative tactics that might optimize sleep health, that is, multidimensional sleep patterns (e.g., duration, efficiency, and quality) contextualized to personal and contextual factors, which give rise to positive health and well-being.…”

Via systematic review with narrative synthesis of findings, we aimed to document the ways by which researchers have defined, operationalized, and examined sleep variability among athletes. We identified studies in which scholars examined intraperson variability in sleep among athletes via a search of six databases (Web of Science, Embase, Medline, PsycINFO, CINHAL Plus, and ProQuest Dissertations and Theses Global) using a protocol that included keywords for the target outcome (sleep*), population (athlet* OR sport*), and outcome operationalization (variability OR variation OR “standard deviation” OR fluctuate OR fluctuation OR stability OR instability OR reactivity OR IIV OR intraindividual). We complemented this primary search with citation searching of eligible articles. Assessments of study quality captured eight core elements, namely aims/hypotheses, sample size justification, sample representativeness, number of days sleep assessed, measures of sleep and its correlates, missing data, and inferences and conclusions. From a total of 1209 potentially relevant papers, we identified 16 studies as meeting our eligibility criteria. Concept definitions of variability were notably absent from this work and where available were vague. Quantitative deviations from one's typical level of target sleep metrics reflected the essence by which all but one of the research teams operationalized sleep variability. We assessed the overall quality of empirical work as moderate in nature. We propose a working definition of sleep variability that can inform knowledge generation on the temporal, day‐to‐day dynamics of sleep functioning that is required for personalized interventions for optimizing sleep health.
