Cross-Sectional and Longitudinal Associations Between Athlete Burnout, Insomnia, and Polysomnographic Indices in Young Elite Athletes

Markus Gerber, Simon Best, Fabienne Meerstetter, Sandrine Isoard-Gautheur, Henrik Gustafsson, Renzo Bianchi, Daniel J. Madigan, Flora Colledge, Sebastian Ludyga, Edith Holsboer-Trachsler, and Serge Brand

). In the present study, we addressed the following research questions: First, we sought to identify the number of young elite athletes exhibiting clinically relevant symptoms of burnout and insomnia. Second, we examined whether athletes above versus below the cutoff for clinically relevant burnout

relationship between physical activity and insomnia. Insomnia—largely characterized by difficulty falling asleep and/or difficulty staying asleep—is prevalent in adulthood ( Mander, Winer, & Walker, 2017 ). The National Sleep Foundation ( 2013 ) reports that 44% of adults in the United States aged 55–84 years

performance, and reduced motor performance ( Lastella et al., 2014 ; Thun et al., 2015 ). Sleep disturbances are common among athletes ( Gerber et al., 2018 ; Montero et al., 2022 ) and can effectively be treated if identified and properly addressed. Insomnia is typically defined as difficulty falling

The COVID-19 Lockdown and Changes in Routine-Oriented Lifestyle Behaviors and Symptoms of Depression, Anxiety, and Insomnia in South Africa

Jonathan P. Davy, Karine Scheuermaier, Laura C. Roden, Candice J. Christie, Alison Bentley, Francesc X. Gomez-Olive, Stella Iacovides, Raphaella Lewis, Gosia Lipinska, Johanna Roche, Andrew Todd, Swantje Zschernack, and Dale E. Rae

The primary aim of the study was to quantify any changes in work, physical activity, screen time, caffeine and alcohol use, and sleep–wake behaviors, as well as symptoms of anxiety, depression, and insomnia before and during the national Alert Level 5 lockdown

Sleep Quality and Recommended Levels of Physical Activity in Older People

Iuliana Hartescu, Kevin Morgan, and Clare D. Stevinson

A minimum level of activity likely to improve sleep outcomes among older people has not previously been explored. In a representative UK sample aged 65+ (n = 926), cross-sectional regressions controlling for appropriate confounders showed that walking at or above the internationally recommended threshold of ≥ 150 min per week was significantly associated with a lower likelihood of reporting insomnia symptoms (OR = 0.67, 95% CI = 0.45−0.91, p < .05). At a 4-year follow-up (n = 577), higher walking levels at baseline significantly predicted a lower likelihood of reporting sleep onset (OR = 0.64, 95% CI = 0.42−0.97, p < .05) or sleep maintenance (OR = 0.63, 95% CI = 0.41−0.95, p < .05) problems. These results are consistent with the conclusion that current physical activity guidelines can support sleep quality in older adults.

Does Habitual Physical Activity Prevent Insomnia? A Cross-Sectional and Longitudinal Study of Elderly Japanese

Sachiko Inoue, Takashi Yorifuji, Masumi Sugiyama, Toshiki Ohta, Kazuko Ishikawa-Takata, and Hiroyuki Doi

Few epidemiological studies have examined the potential protective effects of physical activity on insomnia. The authors thus evaluated the association between physical activity and insomnia in a large population-based study in Shizuoka, Japan. Individual data were obtained from participants in an ongoing cohort study. A total of 14,001 older residents who completed questionnaires were followed for 3 yr. Of these, 10,211 and 3,697 participants were eligible for the cross-sectional and longitudinal analyses, respectively. The authors obtained information about the frequency of physical activity and insomnia. Then, the adjusted odds ratios and 95% confidence intervals between physical activity and insomnia were estimated. Habitual physical activity was related to lower prevalence of insomnia. Frequent physical activity also reduced the incidence of insomnia, especially difficulty maintaining sleep. For elderly people with sufficient mobility and no preexisting disease, high-frequency physical activity (e.g., 5 or more days/wk) may help reduce insomnia.

Influence of Exercise Time of Day on Salivary Melatonin Responses

Lara A. Carlson, Kaylee M. Pobocik, Michael A. Lawrence, Daniel A. Brazeau, and Alexander J. Koch

Background: Sleep deprivation negatively affects cognition, pain, mood, metabolism, and immunity, which can reduce athletic performance. Melatonin facilitates sleepiness and may be affected by the proximity of exercise to sleep. Purpose: To evaluate the influence of exercise time of day on salivary melatonin (s-melatonin) responses. Methods: Twelve regularly exercising men (age 20.75 [0.62] y, height 1.75 [0.04] m, mass 73.63 [10.43] kg, and maximal oxygen consumption 57.72 [6.11] mL/kg/min) participated in a randomized, crossover design. Subjects completed 3 protocols—morning exercise (09:00 h), afternoon exercise (16:00 h), and no exercise (CON)—at least 5 d apart. Exercise sessions consisted of 30 min of steady-state running at 75% of maximal oxygen consumption. Saliva was collected via passive drool at 20:00, 22:00, and 03:00 h following all sessions. Results: Repeated-measures analysis of variance revealed significant time (P = .001) and condition (P = .026) effects for melatonin. Levels of s-melatonin were significantly increased at 03:00 h compared with 20:00 and 22:00 h for all conditions. Post hoc analyses revealed that s-melatonin at 22:00 h was significantly higher after morning exercise (16.5 [7.5] pg/mL) compared with afternoon exercise (13.7 [6.1] pg/mL) sessions (P = .03), whereas neither exercise condition significantly differed from the control (P > .05). Conclusions: It appears that exercising in the afternoon may blunt melatonin secretion compared with morning exercise. If sleep is an issue, morning exercise may be preferable to afternoon exercise.

Aerobic Exercise and Self-Reported Sleep Quality in Elderly Individuals

Glenn S. Brassington and Robert A. Hicks

The purpose of this study was to explore the relationships between aerobic exercise, sleep quality, and daytime sleepiness by examining variables that may be associated with exercise in improving sleep (i.e., anxiety, depression, stress, and minor physical symptoms). Specifically, 33 sedentary and 46 exercising men and women (mean age 73, range 60–82) were asked to complete questionnaires on sleep, anxiety, depression, stress, and minor physical symptoms. Next, subjects were asked to complete a 14-day sleep log. The groups did not differ on a number of control variables: age, gender, trait sociability, trait shyness, number of social contacts, and body mass. Analyses revealed that the exercise group had greater sleep quality in the form of greater sleep duration, less sleep onset latency, and less daytime dysfunction. It was also found that exercise seems to be related to sleep quality and daytime naps independent of the psychological variables; however, exercise seems to be related to the other parameters of sleep by mediating the salience of the psychological variables.

Based on the previous research described above, we make the following two hypotheses: (a) Negative experiences of the COVID-19 pandemic (e.g., infection, quarantine), depression, anxiety or worry, and insomnia will negatively affect student-athlete well-being and QOL and (b) similar to previous findings
