Effects of vigorous late-night exercise on sleep quality and cardiac autonomic activity

2011

Sleep is the most important period for recovery from daily load. Regular physical activity enhances overall sleep quality, but the effects of acute exercise on sleep are not well defined. In sleep hygiene recommendations, intensive exercising is not suggested within the last 3 h before bed time, but this recommendation has not been adequately tested experimentally. Therefore, the effects of vigorous late-night exercise on sleep were examined by measuring polysomnographic, actigraphic and subjective sleep quality, as well as cardiac autonomic activity. Eleven (seven men, four women) physically fit young adults (VO(2max) 54±8 mL·kg(-1)·min(-1) , age 26±3 years) were monitored in a sleep labor…

A survey on sleep questionnaires and diaries.

2017

[EN] Sleep assessment is a fundamental part of health evaluation. In fact, many diseases (such as obesity, diabetes, or hypertension, as well as psychiatric, neurological, and cardiovascular diseases) produce sleep disorders that are often used as indicators, diagnosis (symptoms), or even as predictors (eg, for depression) of health. For this reason, many efforts have been devoted to designing methods to control and report on sleep quality. Two of the most used sleep assessment tools are sleep questionnaires and sleep diaries. Both methods have a very low cost are easy to administer do not require a sleep centre (unlike, eg, polysomnography), and can be self-administered. Most important, as…

Analysis of the sleep period and the amount of habitual snoring in individuals with sleep bruxism

2019

Background The literature does not report any association between habitual snoring and sleep bruxism, but these situations can be a reason for frequent complaints of individuals, impairing the quality of life. This study was performed to investigate the sleep period and amount of habitual snoring in individuals with sleep bruxism observing expiratory, inspiratory, and mixed snoring. Material and Methods A total of 90 individuals were screened and divided into the following groups: with sleep bruxism (n=45) and those without sleep bruxism (n=45). Single night sleep polysomnography was performed to diagnose sleep bruxism, quantify habitual snoring and sleep period. The results were tabulated …

Dimensional analysis of the upper airway in obstructive sleep apnoea syndrome patients treated with mandibular advancement device: A bi‐ and three‐di…

2020

BACKGROUND The efficiency of the mandibular advancement device (MAD) in patients with obstructive sleep apnoea syndrome (OSAS) has been demonstrated. Nevertheless, the behaviour of the upper airway once MAD is placed and titrated, and its correlation with the apnoea-hypopnoea index (AHI) is still under discussion. OBJECTIVES To analyse the morphological changes of the upper airway through a bi- and three-dimensional study and correlate it with the polysomnographic variable, AHI. METHODS Patients were recruited from two different hospitals for the treatment of OSAS with a custom-made MAD. A cone-beam computer tomography and a polysomnography were performed at baseline and once the MAD was ti…

Editorial commentary: Sleep disordered breathing and cardiovascular outcomes: is it time to change our thinking?

Both daily demands as well as training and competition characteristics in sports can result in a psychobiological state of mental fatigue leading to feelings of tiredness, lack of energy, an increased perception of effort, and performance decrements. Moreover, optimal performance will only be achievable if the balance between recovery and stress states is re-established. Consequently, recovery strategies are needed aiming at mental aspects of recovery. The aim of the study was to examine acute effects of potential mental recovery strategies (MR) on subjective-psychological and on cognitive performance outcomes after a mentally fatiguing task. A laboratory-based randomized cross-over study w…

Prevalence of physician-diagnosed asthma in patients with suspected obstructive sleep apnea syndrome: A cross-sectional analysis of the ESADA database

2015

It has been reported that bronchial asthma is often associated with obstructive sleep apnea (OSA) and daytime sleepiness. We analyzed the prevalence of physician-diagnosed asthma in 4929 subjects with suspected obstructive sleep apnea (OSA) in the European Sleep Apnea database (ESADA) Cohort. Patients were studied by respiratory polygraphy (PG: n=1624, 66.6% males) or full polysomnography (PSG: n=3305, 70.4% males), and the clinical characteristics of asthmatic (A) and non-asthmatic (non-A) patients were analyzed according to OSA severity. Significance was at p 2 , p=0.0004) and showed more severe daytime sleepiness (Epworth score: 10.4±5.6 vs 9.5±5.3, p=0.0015) and a trend for worse noctur…

Hypoxic burden and angiogenic factors in patients with myocardial infarction and obstructive sleep apnea

2019

Introduction: The amount and severity of hypoxia have been related to risk of cardiovascular events. Aim: To determine the relationship between nocturnal hypoxic burden and pro- angiogenic factors in patients with obstructive sleep apnea (OSA) and myocardial infarction (MI). Method: A prospective, observational study in patients with a first acute MI. Eligible patients underwent a polysomnography within 30 days after MI, and a serum blood sample was drawn in order to measure a panel of angiogenic factors by Luminex technology. A hypoxic burden index (HBI) was calculated as the integral area under the desaturation curve (obtained by calculating the integral of the oxygen saturation reduction…

Intensity of Respiratory Cortical Arousals Is a Distinct Pathophysiologic Feature and Is Associated with Disease Severity in Obstructive Sleep Apnea …

2021

Background: We investigated whether the number, duration and intensity of respiratory arousals (RA) on C3-electroencephalographic (EEG) recordings correlate with polysomnography (PSG)-related disease severity in obstructive sleep apnea (OSA) patients. We also investigated if every patient might have an individual RA microstructure pattern, independent from OSA-severity. Methods: PSG recordings of 20 OSA patients (9 female
