Exercise Physiology: Energy, Nutrition and Human Performance

Objective: The recent obesity epidemic has been accompanied by a parallel growth in chronic sleep deprivation. Physiologic studies suggest sleep deprivation may influence weight through effects on appetite, physical activity, and/or thermoregulation. This work reviews the literature regarding short sleep duration as an independent risk factor for obesity and weight gain.

Sleep Disturbance, Sleep Duration, and Inflammation: A Systematic Review and Meta-Analysis of Cohort Studies and Experimental Sleep Deprivation

Sleep has a critical role in promoting health. Research over the past decade has documented that sleep disturbance has a powerful influence on the risk of infectious disease, the occurrence and progression of several major medical illnesses including cardiovascular disease and cancer, and the incidence of depression. Increasingly, the field has focused on identifying the biological mechanisms underlying these effects. This review highlights the impact of sleep on adaptive and innate immunity, with consideration of the dynamics of sleep disturbance, sleep restriction, and insomnia on (a) antiviral immune responses with consequences for vaccine responses and infectious disease risk and (b) proinflammatory immune responses with implications for cardiovascular disease, cancer, and depression. This review also discusses the neuroendocrine and autonomic neural underpinnings linking sleep disturbance and immunity and the reciprocal links between sleep and inflammatory biology. Finally, interventions are discussed as effective strategies to improve sleep, and potential opportunities are identified to promote sleep health for therapeutic control of chronic infectious, inflammatory, and neuropsychiatric diseases.

Why Sleep Is Important for Health: A Psychoneuroimmunology Perspective

Physical function limitation is a common disorder in chronic hemodialysis (HD) patients, relating to increased morbidity and mortality. The aim of this study was to determine the effects of aerobic and resistance trainings on blood lipids and inflammation status in HD patients. Out of 30 volunteer males who had been undergoing conventional maintenance HD within an HD unit in Tehran, 21 subjects were enrolled. They were randomly assigned into aerobic exercise group – resistance training group undergoing an 8-week intradialytic exercise program (three times/week) and control group (n = 7, each). Training program consisted of 10-30 min stationary cycling at an intensity of 12–16 out of 20 at the rate of perceived exertion (RPE) of Borg scale in aerobic group and using ankle weights for knee extension, hip abduction and flexions at an intensity of 15–17 out of 20 at the RPE of Borg scale in resistance group. Fasting blood samples for serum biochemistry were drawn at baseline and 8 weeks. The age, HD duration, and physical activity score were 51.6±18.9yrs; 25.1±13.9 mo, and 19.2±7.6, respectively. Diabetes mellitus (43%), hypertension (28%), and obstructive uropathy (14%) were the most common underlying diseases. Aerobic and resistance exercises were correlated with serum creatinine (P 0.05). Both intradialytic aerobic and resistance exercises showed beneficial effects on inflammation status without any influences on serum lipid levels probably due to short duration of the study which was not accompanied with body weight changes. Solute removal had no change during exercise programs. There is a need for more investigation on the role of exercise in HD patients.

Purpose: The inflammatory state of adipose tissue in obese subjects may be the most important factor linking increased adipose tissue mass to insulin resistance. Chemerin is a newly discovered adipokine that plays an important role in macrophage infiltration into adipose tissue and may contribute to the development of inflammation and insulin resistance. We examined the effects of 12 weeks of aerobic training on serum chemerin levels in association with cardiovascular risk factors in overweight and obese males. Methods: Twenty-one overweight and obese subjects [44.3 (4.1 yrs, body mass index (BMI) ?25 kg/m2) were assigned to exercise training (obese EX, n= 11) and control (obese CON, n= 10) groups. The obese EX group participated in 12 weeks of progressive aerobic training 5 days a week. Serum chemerin, insulin resistance, lipid profiles, blood pressure, and body composition were all measured before and after the training. Results: After the aerobic training, waist circumference ( P =0.009), fat percent ( P =0.03), visceral fat ( P =0.03), subcutaneous fat ( P =0.01), fasting glucose ( P =0.01), insulin resistance ( P =0.03), triglyceride ( P =0.05), total cholesterol ( P =0.04), low-density lipoprotein cholesterol ( P =0.05) and systolic blood pressure ( P =0.04) of participates were significantly decreased. Concurrently, serum chemerin concentrations were significantly decreased after aerobic program ( P =0.02). Conclusion: Aerobic training caused an improvement in cardiometabolic risk factors in obese subjects, and this improvement was accompanied by decreased chemerin levels.

Twelve-week aerobic training decreases chemerin level and improves cardiometabolic risk factors in overweight and obese men.

Introduction. Sleep disorders are common in hemodialysis patients. They can affect their quality of life. The purpose of this study was to evaluate the effects of aerobic training on sleep quality, inflammatory status, and serum leptin levels in hemodialysis patients. Materials and Methods. Twenty-eight men in the age range of 28 to 74 years who were on maintenance hemodialysis and had sleep problems were enrolled in this study. They were randomly assigned into control and training groups (14 patients in each group). Patients in the training group performed a 10- to 30-minute stationary cycling, 3 times a week, during the 1st two hours of every dialysis session, for 8 weeks. The Pittsburgh Sleep Quality Index and the Baecke questionnaire on physical activity were filled out for all participants. To assess serum leptin and C-reactive protein levels, blood samples were drawn before the beginning and at the end of the eighth week. Results. At the end of the study, serum leptin and C-reactive protein levels were significantly reduced (P < .001 and P < .001, respectively). Furthermore, the Pittsburgh Sleep Quality Index scores of the training group declined significantly after 8 weeks (P < .001). There was a positive correlation between sleep quality and serum levels of leptin and C-reactive protein (P = .03 and P = .04, respectively). Conclusions. Aerobic exercise with moderate intensity during the first two hours of a dialysis session could improve sleep quality and inflammatory status of hemodialysis patients, which predicts morbidity, mortality, and quality of life. However, additional research is needed to confirm these effects.
