Article Abstract
Background: Sleep and physical performance are strongly related and mutually influence each other. Athletes, particularly in disciplines like offshore sailing and ultra-endurance sports, often suffer from sleep deprivation due to factors like irregular training times, travel, and the extended duration of events like 100-mile mountain races. Despite growing interest in sleep's role in sports science, few studies have specifically investigated the sleep patterns of ultramarathon runners. This study aimed to investigate sleep patterns and sleep management strategies in ultramarathons, and the repercussions of sleep deprivation during and after races.
Methods: This cross-sectional study using e-survey was conducted on 1154 runners from two ultramarathons (a 165 km race with 9,576 m positive elevation; 2018 finish time [23:18:48-66:04:00], and a 111 km race with 6,433 m elevation; [15:34:56 - 41:54:16]).
Results: The results revealed that 58% of the runners reported implementing sleep management strategies before or during the race. Most runners began the race with some level of sleep debt (-50 min a week before the race). During the races, 77% of runners slept, with the cumulative sleep duration varying based on race duration and the number of nights spent on the race (76 min at 165 km and 27 min at 111 km). Short naps lasting less than 30 min were the most popular strategy. The prevalence of symptoms attributed to sleep deprivation during the race was high (80%), with reported falls and hallucinations. After the race, runners reported recovering a normal state of wakefulness relatively quickly (within two days); 22% believed that sleep deprivation during the race increased the risk of accidents in everyday life.
Conclusion: This study provides valuable insights into sleep patterns and strategies in ultramarathon running and emphasizes the importance of adequate sleep management for performance and post-race recovery.

Acute sleep deprivation (SD) rapidly alleviates depression, addressing a critical gap in mood disorder treatment. Rapid eye movement SD (REM SD) modulates the excitability of vasoactive intestinal peptide (VIP) neurons, influencing the synaptic plasticity of pyramidal neurons. However, the precise mechanism remains undefined.

Background: Affective disorders represent a major global health burden. Animal models are widely used for modeling brain disorders and neuroactive drug discovery. A novel powerful tool in translational neuroscience research, zebrafish provide multiple behavioral assays relevant to anxiety-like and depression-related conditions (including despair-like behavior, a common feature in depression).

Sleep deprivation (SD) is a major contributor to cognitive impairment, often accompanied by central neuroinflammation and gut microbiota dysbiosis. The tryptophan (TRP) pathway, activated via indoleamine 2,3-dioxygenase (IDO), serves as a critical link between immune activation and neuronal damage. Umbelliferone (UMB), a naturally occurring coumarin compound, possesses anti-inflammatory, antioxidant, and microbiota-modulating properties.

Consistent sleep patterns are associated with better cardiovascular health, while sleep loss is known to impair vascular function. This study examined whether consistent sleep could improve vascular function and mitigate the negative effect of 25-hour total sleep deprivation. Sixteen healthy adults (10 females, 6 males; 34 ± 9 years; BMI: 25 ± 3 kg/m²) completed a randomized crossover study involving two 12-night sleep conditions, habitual sleep and a consistent sleep/wake schedule that were separated by a 1-2-week washout.
