Abstract
Background In a randomized, controlled trial, we showed that high-intensity rehabilitation, combining resistance training and body-weight interval training, improves sleep efficiency in Parkinson's disease (PD). Quantitative sleep EEG (sleep qEEG) features, including sleep spindles, are altered in aging and in neurodegenerative disease. Objective The objective of this post-hoc analysis was to determine the effects of exercise, in comparison to a sleep hygiene, no-exercise control group, on the quantitative characteristics of sleep spindle morphology in PD. Methods We conducted an exploratory post-hoc analysis of 24 PD participants who were randomized to exercise (supervised 3 times/week for 16 weeks) versus 26 PD participants who were assigned to a sleep hygiene, no-exercise control group. At baseline and post-intervention, all participants completed memory testing and underwent polysomnography (PSG). PSG-derived sleep EEG central leads (C3 and C4) were manually inspected, with rejection of movement and electrical artifacts. Sleep spindle events were detected based on the following parameters: (1) frequency filter = 11–16 Hz, (2) event duration = 0.5–3 s, and (3) amplitude threshold 75% percentile. We then calculated spindle morphological features, including density and amplitude. These characteristics were computed and averaged over non-rapid eye movement (NREM) sleep stages N2 and N3 for the full night and separately for the first and second halves of the recording. Intervention effects on these features were analyzed using general linear models with group x time interaction. Significant interaction effects were evaluated for correlations with changes in performance in the memory domain. Results A significant group x time interaction effect was observed for changes in sleep spindle density due to exercise compared to sleep hygiene control during N2 and N3 during the first half of the night, with a moderate effect size. This change in spindle density was positively correlated with changes in performance on memory testing in the exercise group. Conclusions This study is the first to demonstrate that high-intensity exercise rehabilitation has a potential role in improving sleep spindle density in PD and leading to better cognitive performance in the memory domain. These findings represent a promising advance in the search for non-pharmacological treatments for this common and debilitating non-motor symptom.

FRONTIERS IN NETWORK PHYSIOLOGY 2022; 2:869787. [PMID: 36926086 PMCID: PMC10013041 DOI: 10.3389/fnetp.2022.869787] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 03/29/2022] [Indexed: 12/13/2022]
Abstract
Introduction: High-intensity interval exercise (HIIE) is deemed effective for cardiovascular and autonomic nervous system (ANS) health-related benefits, while ANS disturbance increases the risk for cardiovascular disease (CVD). Postprandial lipemia and acute-partial sleep deprivation (APSD) are considered as CVD risk factors due to their respective changes in ANS. Exercising in the morning hours after APSD and have a high-fat breakfast afterwards may alter the interactions of the cardiovascular, autonomic regulation, and postprandial lipemic systems threatening individuals' health. This study examined postprandial network interactions between autonomic regulation through heart rate variability (HRV) and lipemia via low-density lipoprotein (LDL) cholesterol in response to APSD and HIIE. Methods: Fifteen apparently healthy and habitually good sleepers (age 31 ± 5.2 SD yrs) completed an acute bout of an isocaloric HIIE (in form of 3:2 work-to-rest ratio at 90 and 40% of VO2 reserve) after both a reference sleep (RSX) and 3-3.5 h of acute-partial sleep deprivation (SSX) conditions. HRV time and frequency domains and LDL were evaluated in six and seven time points surrounding sleep and exercise, respectively. To identify postprandial network interactions, we constructed one correlation analysis and one physiological network for each experimental condition. To quantify the interactions within the physiological networks, we also computed the number of links (i.e., number of significant correlations). Results: We observed an irruption of negative links (i.e., negative correlations) between HRV and LDL in the SSX physiological network compared to RSX. Discussion: We recognize that a correlation analysis does not constitute a true network analysis due to the absence of analysis of a time series of the original examined physiological variables. Nonetheless, the presence of negative links in SSX reflected the impact of sleep deprivation on the autonomic regulation and lipemia and, thus, revealed the inability of HIIE to remain cardioprotective under APSD. These findings underlie the need to further investigate the effects of APSD and HIIE on the interactions among physiological systems.

Abstract
Sleep deprivation in healthy adults has been associated with disrupted autonomic nervous system function, which in turn has been linked to cardiovascular health. High-intensity interval exercise (HIIE) may affect both sleep and cardiac autonomic modulation. Purpose: To investigate the impact of acute partial sleep deprivation on autonomic cardiac regulation before and after an acute bout of HIIE and the length of time for the autonomic system to return to resting levels. Methods: Fifteen healthy males with body mass index (BMI) of 25.8 ± 2.7 kg·m-2 and age 31 ± 5 y participated in a reference sleep (~9.5 hr) with no HIIE (RS), a reference sleep with HIIE (RSX), and an acute partial sleep deprivation (~3.5 hr) with HIIE (SDX). HIIE was performed in 3:2 intervals at 90% and 40% of VO2 reserve. Autonomic regulation through HRV selected time and frequency domain indices were recorded the night before, the morning of the next day, 1 hr-, 2 hr-, 4hr-, and 6-hr post-exercise. Results: HIIE performed in a 3:2 W:R ratio decreased the HRV (p < .05) at 1-hr post exercise and it took up to 4 hr to return to baseline levels. Parasympathetic related HRV indices increased the morning of the next day for SDX (p < .05). Acute partial sleep deprivation and HIIE did not modify the HRV responses compared to reference sleep and HIIE. Conclusion: HRV disturbance typically seen in responses to an acute episode of HIIE is not influenced by acute partial sleep deprivation.

Abstract
OBJECTIVE To analyze the association between the continuous physical activity (PA) at different life stages with sleep quality in adults. METHODS This is an observational study with a cross-sectional design. A sample of 843 adults (61.7% female) with a mean age of 56.6 (±18.3) years was randomly selected. The PA at different life stages was assessed retrospectively in childhood and adolescence, and the current PA was assessed by Baecke Physical Activity Questionnaire. Sleep quality was assessed using the Mini-Sleep Questionnaire. Variables of sex, age group, ethnicity, socioeconomic status, and current physical activity were covariates. The association between continuous PA at different life stages with sleep quality was analyzed by binary logistic regression models. RESULTS Overweight adults who practiced PA in adolescence were 46% less likely to have poor sleep quality when compared to those who did not practice physical activity in this life stage (Odds ratio = 0.54, p = 0.031). Adults who continued to practice PA at youth and adulthood were 49% less likely to have poor sleep quality when compared to those without continuous PA (Odds ratio = 0.51, p = 0.009). CONCLUSIONS Poor sleep quality was negatively associated with continuous PA between youth and adulthood in overall sample and negatively associated with PA in adolescence among overweight adults.

Abstract
BACKGROUND Exercise has been found to be associated with improved sleep quality. However, most of the evidence is based on resistance exercise, walking, or gym-based aerobic activity. PURPOSE This study aimed to examine the effects of an 8-week aquatic exercise program on objectively measured sleep parameters among older adults with mild sleep impairment. METHODS A total of 67 eligible older adults with sleep impairment were selected and randomized to exercise and control groups, and 63 participants completed the study. The program involved 2 × 60-min sessions of aquatic exercise for 8 weeks. Participants wore wrist actigraphs to assess seven parameters of sleep for 1 week before and after the intervention. Mixed-design analysis of variance (ANOVA) was used to assess the differences between groups in each of the sleep parameters. RESULTS No significant group differences on demographic variables, life satisfaction, percentage of body fat, fitness, seated blood pressure, and any parameter of sleep were found at baseline. Significant group × time interaction effects were found in sleep onset latency, F(1,58) = 6.921, p = .011, partial eta squared = .011, and in sleep efficiency, F(1, 61) = 16.909, p < 0.001, partial eta squared = .217. The exercise group reported significantly less time on sleep onset latency (mean difference = 7.9 min) and greater sleep efficiency (mean difference = 5.9 %) than the control group at posttest. There was no significant difference between groups in change of total sleep time, wake after sleep onset, activity counts, or number and length of awakenings. CONCLUSIONS An 8-week aquatic exercise has significant benefits on some sleep parameters, including less time for sleep onset latency and better sleep efficiency in older adults with mild sleep impairment.
