Background Assessment of sleep quality is essential to address poor and understand changes. Owing the advances in Internet Things wearable technologies, monitoring under free-living conditions has become feasible practicable. Smart rings smartwatches can be employed perform mid- or long-term home-based monitoring. However, validity such wearables should investigated terms parameters. Sleep validation studies are mostly limited short-term laboratory tests; there a need for study assess attributes everyday settings, where users engage their daily routines.

Sex differences in sleep and influence of the menstrual cycle on women’s sleep in junior endurance athletes

PLoS ONE, Journal Year: 2021, Volume and Issue: 16(6), P. e0253376 - e0253376

Previous research shows that female athletes sleep better according to objective parameters but report worse subjective quality than male athletes. However, existing studies did not investigate variations in and stages over longer periods have, so far, elucidated the role of menstrual cycle athletes’ sleep.

Sleep Patterns Fluctuate Following Training and Games across the Season in a Semi-Professional, Female Basketball Team

Brain Sciences, Journal Year: 2023, Volume and Issue: 13(2), P. 238 - 238

Quantifying athlete sleep patterns may inform development of optimal training schedules and strategies, considering the competitive challenges faced across season. Therefore, this study comprehensively quantified a female basketball team examined variations in between nights. Seven semi-professional, players had their monitored using wrist-worn activity monitors perceptual ratings during 13-week in-season. Sleep variables were compared different nights (control nights, before games, non-congested game congested nights), generalized linear mixed models, as well Cohen’s d odds ratios effect sizes. Players experienced less on games to control (p < 0.05, = 0.43–0.69). also exhibited later onset times 0.01, 0.68), earlier offset following all other 0.74–0.79). Moreover, attaining better perceived quality was 88% lower than 0.001). While attained an adequate duration (7.3 ± 0.3 h) efficiency (85 2%) average in-season, they susceptible poor games. Although limited team-based case series design, these findings suggest coaches need reconsider scheduling team-based, on-court sessions prior consider implementing suitable psychological recovery strategies around optimize player sleep.

The Effect of Sleep Quality and Quantity on Athlete's Health and Perceived Training Quality

Frontiers in Sports and Active Living, Journal Year: 2021, Volume and Issue: 3

University athletes are unique because they not only have to cope with the normal psycho-physiological stress of training and playing sport, but also need accommodate associated their academic studies along considerable from social environment. The ability manage adapt ultimately helps improve athletic performance, when becomes too much for athlete, it can result in maladaptation's including sleep disruption which is performance loss, negative mood changes, even injury or illness. This research aimed determine if quantity quality were maladaptation university athletes. We examined subjective measures duration state, energy levels, stress, quantity, frequency illness 82 young (18–23 years) elite over a 1 year period 2020. Results indicate decreased first few weeks coincided increased training, stress. Regression analysis indicated levels perceived (1.3, 1.1–1.5, Odds Ratio 95% confidence limits), (2.9, 2.5–3.3), (1.2, 1.0–1.4), 1.1–1.5), improved (1.1, 1.0–1.3) ≥8 h sleep. Athletes that slept had higher less likely suffer injury/illness (0.8, 0.7–0.9, 0.6, 0.5–0.7 quality, respectively). In conclusion, who maintain good habits (sleep h/night high scores) problems elevated levels. Educating athletes, coaches, trainers signs symptoms excessive (including deprivation) may help reduce athlete's outcomes.

Published: Jan. 20, 2025

This study aimed to examine the sleep parameters and sleep/wake regularity of a cohort student-athletes who start training between 06:30 07:00. Twenty-one male Rugby Union players, aged 21 ± 2 years competing at national level, were assessed using actigraphy over two weeks, Athlete Sleep Screening Questionnaire (ASSQ). Sleep/wake was calculated Regularity Index (SRI). Wilcoxon signed-rank tests showed that nocturnal preceding morning had significantly shorter duration (1.8 hr, r = .67), advanced onset (0.9 .50) offset times (3.2 .85) compared free days. The variability demands resulted in an inconsistent pattern consecutive days, resulting median SRI score 67.0 (interquartile range: 17.0). Pearson correlations revealed lower associated with higher daily including naps (r -.62), delayed -.50) -.60), later chronotype ASSQ .52). These findings indicate early is factor contributing irregular patterns student-athletes, where feasible should be scheduled alternative time.
