Sleep is an important determinant of collegiate athlete health, well-being and performance. However, collegiate athlete social and physical environments are often not conducive to obtaining restorative sleep. Traditionally, sleep has not been a primary focus of collegiate athletic training and is neglected due to competing academic, athletic and social demands. Collegiate athletics departments are well positioned to facilitate better sleep culture for their athletes. Recognising the lack of evidence-based or consensus-based guidelines for sleep management and restorative sleep for collegiate athletes, the National Collegiate Athletic Association hosted a sleep summit in 2017. Members of the Interassociation Task Force on Sleep and Wellness reviewed current data related to collegiate athlete sleep and aimed to develop consensus recommendations on sleep management and restorative sleep using the Delphi method. In this paper, we provide a narrative review of four topics central to collegiate athlete sleep: (1) sleep patterns and disorders among collegiate athletes; (2) sleep and optimal functioning among athletes; (3) screening, tracking and assessment of athlete sleep; and (4) interventions to improve sleep. We also present five consensus recommendations for colleges to improve their athletes’ sleep.
DORAs offer an additional treatment option for insomnia. More clinical trials are needed to robustly evaluate their safety and effectiveness in several subclasses of individuals with insomnia. Given the published literature, head-to-head comparisons to existing treatment for insomnia are warranted.
Tobacco use and depression/anxiety disorders are both independently associated with more sleep problems in college students. Students with depression and/or anxiety are more likely to be daily tobacco users, which likely exacerbates their sleep problems.
The genetic and epigenetic influences that establish and maintain the unique phenotype of the extraocular muscles (EOMs) are poorly understood. The vestibulo-ocular reflex (VOR) represents an important input into the EOMs, as it stabilizes eye position relative to the environment and provides a platform for function of all other eye movement systems. A role for vestibular cues in shaping EOM maturation was assessed in these studies using the ototoxic nitrile compound 3',3'-iminodipropionitrile (IDPN) to eliminate the receptor hair cells that drive the vestibulo-ocular reflex. Intraperitoneal injections of IDPN were followed by a 2-week survival period, after which myosin heavy chain (MyHC) analysis of the EOMs was performed. When IDPN was administered to juvenile rats, the proportion of eye muscle fibers expressing developmental and fast myosins was increased, while EOM-specific MyHC mRNA levels were downregulated. By contrast, IDPN treatment in adult rats affected only the proportion of fibers expressing developmental MyHC isoforms, leaving the EOM-specific MyHC mRNA unaltered. These data provide evidence that the VOR modulates EOM-specific MyHC expression in development. The lack of significant changes in EOM-specific MyHC expression in adult EOM following IDPN administration suggests that there may be a critical period during development when alterations in vestibular activity have significant and permanent consequences for the eye muscles.
The present study investigates risk behaviors, sleep habits, and mental health factors associated with caffeinated beverage use in young adults. Students from a midsize private university ( = 159) completed a 15-minute anonymous questionnaire, including questions on risk behaviors, sleep habits, alcohol, and caffeine consumption. We compared behaviors between the top ∼15% ("high end") of energy drink users (≥3/month) and coffee users (≥16/month) to those with less frequent or no caffeine consumption. Caffeine consumption was frequent among young adults. In the last month, 36% of students had an energy drink, 69% had coffee or espresso, and 86% reported having any caffeine; however, the majority of students were unaware of the caffeine content in these beverages. High-end energy drink consumers reported more risk-taking behaviors (increased drug and alcohol use and less frequent seat belt use), sleep disturbances (later bedtimes, harder time falling asleep, and more all-nighters), and higher frequency of mental illness diagnoses than those who consumed fewer energy drinks. In contrast, the frequency of most risk behaviors, sleep disturbances, and mental illness diagnoses was not significantly different between the high-end and general population of coffee drinkers. Students with delayed sleep patterns, mental illness, and higher frequency of substance use and risk behaviors were more likely to be regular energy drink users but not regular coffee drinkers. It is unclear whether the psychoactive content in energy drinks results in different behavioral effects than just caffeine in coffee, and/or different personality/health populations are drawn to the two types of beverages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
