ACTIVE NOT RECRUITING

NCT04037605

Hormonal Mechanisms of Sleep Restriction - Axis Study in Older Men and Postmenopausal Women

The purpose of this study is to 1) determine how hypothalamic-pituitary-adrenal axis (HPA axis) activation occurs with sleep restriction and 2) evaluate how hypothalamic-pituitary-gonadal axis (HPG axis) deactivation occurs with sleep restriction. The investigator will also examine the cognitive function associated with sleep restriction, including food intake and food cravings.

NCT03377543

Sleep and Inflammatory Resolution Pathway

Goal of this project is to investigate whether increases in inflammation that result from common patterns of restricting sleep on week nights and catching up on sleep over the weekend are caused by disruption in the newly discovered inflammatory resolution pathways. These pathways are crucial in the active termination of the inflammatory response, and their disruption may contribute to ongoing unresolved inflammation, which has been observed not only during periods of sleep restriction, but also after recovery sleep has been obtained. If the hypothesis is true, it is possible that increasing the body's natural production of endogenous, inflammatory resolution mediators may provide a non-behavioral strategy to limit the inflammatory consequences in those undergoing periods of sleep restriction with intermittent recovery sleep.

Acoustic Stimulation During Restricted Sleep After Sleep Deprivation

The purpose of this study is to determine if brief sounds or tones presented within a restricted period of recovery sleep after a period of sleep deprivation will enhance restorative properties and improve performance during a subsequent period of wakefulness.

NCT06223776

Effects of Sleep Restrictions on Maximal Strength, Muscle Power, and Strength Endurance in Resistance-trained Women.

The study aims to see how acute sleep restriction will affect women resistance trainers. Above all, the investigators will be interested in observing the relationship between shorter sleep and athletic performance, as well as other important aspects, such as their level of motivation to exercise, how much pain participants felt during exercise and how demanding they found exercise. The investigators assume that differences in subjective measures (such as pain levels, motivation and mood) will be most apparent.
