TL;DR: The runners showed less rapid eye-movement activity during sleep than the nonrunners under both experimental conditions, indicating a strong and unexpected effect of physical fitness on this measure.
Abstract: We tested the hypothesis that EEG sleep stages 3 and 4 (slow-wave sleep, SWS) would be increased as a function of either acute of chronic exercise. Ten distance runners were matched with 10 nonrunners, and their sleep was recorded under both habitual (runners running and nonrunners not running, 3 night) and abruptly changed (runners not running and nonrunners running, 1 night) conditions. Analyses of both visually scored SWS and computer measures of delta activity during non-rapid eye-movement (NREM) sleep failed to support the SWS-exercise hypothesis. The runners showed a significantly higher proportion and a greater absolute amount of NREM sleep than the nonrunners. The runners showed less rapid eye-movement activity during sleep than the nonrunners under both experimental conditions, indicating a strong and unexpected effect of physical fitness on this measure. Modest afternoon exercise in nonrunners was associated with a strong trend toward elevated heart rate during sleep. Mood tests and personality profiles revealed few differences, either between groups or within groups, as a function of exercise.

TL;DR: A meta-analytical review of the effects of acute and regular exercise on sleep, incorporating a range of outcome and moderator variables, reveals that acute exercise has small beneficial effects on total sleep time, sleep onset latency, sleep efficiency, stage 1 sleep, and slow wave sleep.
Abstract: A significant body of research has investigated the effects of physical activity on sleep, yet this research has not been systematically aggregated in over a decade. As a result, the magnitude and moderators of these effects are unclear. This meta-analytical review examines the effects of acute and regular exercise on sleep, incorporating a range of outcome and moderator variables. PubMed and PsycINFO were used to identify 66 studies for inclusion in the analysis that were published through May 2013. Analyses reveal that acute exercise has small beneficial effects on total sleep time, sleep onset latency, sleep efficiency, stage 1 sleep, and slow wave sleep, a moderate beneficial effect on wake time after sleep onset, and a small effect on rapid eye movement sleep. Regular exercise has small beneficial effects on total sleep time and sleep efficiency, small-to-medium beneficial effects on sleep onset latency, and moderate beneficial effects on sleep quality. Effects were moderated by sex, age, baseline physical activity level of participants, as well as exercise type, time of day, duration, and adherence. Significant moderation was not found for exercise intensity, aerobic/anaerobic classification, or publication date. Results were discussed with regards to future avenues of research and clinical application to the treatment of insomnia.

TL;DR: A comprehensive account of contemporary research examining the anxiolytic effects of exercise for anxiety disorders is provided, synthesize pertinent research regarding the effects of various types of exercise within the different anxiety disorders, and considers impact of various kinds of exercise regimens on anxiety.
Abstract: Research over the past few decades has focused on the therapeutic effects of physical exercise among those affected by mood disorders. Only recently has attention turned to maladaptive and persistent expressions of anxiety, with a growing body of evidence indicating promise for exercise as an effective treatment for some of the anxiety disorders. The current review provides a comprehensive account of contemporary research examining the anxiolytic effects of exercise for anxiety disorders. We synthesize pertinent research regarding the effects of various types of exercise within the different anxiety disorders, consider impact of various types of exercise regimens on anxiety, and examine potential anxiolytic mechanisms responsible for positive mental health gains. We conclude with important considerations for implementing exercise as a treatment for clinically significant anxiety as well as future research directions.
