Filter by:The overall aim of this project is to compare protein supplementation on performance, recovery, and body composition changes in adolescent soccer players between the whey protein and the control group in response to the 10-12-week intervention.
The aim of this study is to investigate the effect of oral ketone ester administration on sleep architecture. To investigate this, the investigators use a randomised, placebo-controlled, cross-over research design. The study comprises three experimental sessions, each separated by a one-week washout period. Two of the three experimental sessions consist of a 120 minutes cycling endurance training session (ET) two hours after breakfast and an evening high-intensity-interval training (HIIT) ending one hour before bedtime. After each training session, and 30 minutes before sleeptime, subjects receive a ketone ester or a control drink . To investigate the effects of strenuous exercise on sleep alone, an additional experimental session without exercise is added. Before bedtime, a venous blood sample is taken to evaluate hormones playing an important role in sleep regulation. During the experimental sessions, the subjects sleep in a sleep facility to evaluate quality of sleep. Time spent in different sleep phases is measured via polysomnography (PSG). Urine output throughout the day and night will be collected for measurement of urinary excretion of adrenaline and noradrenaline as an index of intrinsic sympathetic activity.
The aim of this trial is to evaluate the efficacy of an intervention (delivered through a smartphone) for improving the mood, physical activity, and sleep of medical interns.
The purpose of the study is to examine the feasibility, acceptability, and initial outcomes of clinical decision support (CDS) and a Sleep Navigation program to enhance primary to specialty care management of pediatric sleep-disordered breathing (SDB).
This project will investigate traditional sleep routines and the current sleep environment in American Indian children to develop a culturally appropriate and novel sleep intervention to increase total sleep time for families with K-3rd grade children. The outcomes of this study will provide a comprehensive understanding of a relatively unknown behavior (sleep) in American Indians, show results from a novel sleep intervention in a high risk and underserved population, and will also contribute to the research and training development of an American Indian investigator, all defined missions of NHLBI.
This study aims to to test effects of sleep loss on perceived discrimination and cardiovascular functioning as well as identify moderators of the racial discrimination and objective sleep link in a sample of 80 African Americans.
The purpose of this study is to examine the impact that sleep duration has on blood pressure (BP) levels during sleep. The investigator will examine the effect of an 8-week sleep hygiene/extension intervention vs. control on sleep BP.
The proposed longitudinal project aims to understand parental influences on children's sleep and will investigate the effect of sleep-related parental factors - (1) parents' value of their children's sleep relative to other activities, (2) parental involvement in setting children's sleep habits and enforcing good sleep hygiene, and (3) parent's own sleep habits - on school-age children's sleep, mental health, socio-emotional resilience, and academic/cognitive performance. It will also investigate the impact of social economic status on these sleep -related parental factors.
This study will evaluate the impact of sleep, circadian health and melatonin on flu vaccine immunogenicity.
This research aims to determine the effect of acupressure applied to nurses actively working in internal clinics on sleep quality and fatigue during the COVID-19 pandemic process. This research hypothesizes that acupressure improves sleep quality and reduces fatigue.
