1. Bilevel positive airway pressure improves the autonomic balance in the postoperative period following cardiac surgery: a randomized trial
RESUMO O uso da pressão positiva de duplo nível nas vias aéreas (BiPAP) tem repercussões sobre desfechos cardiorrespiratórios. No entanto a influência da BiPAP na modulação do sistema nervoso autônomo no pós-operatório de cirurgia cardíaca ainda não foi explorada. O objetivo do estudo foi avaliar os efeitos da BiPAP na saturação periférica de

2. Vitamin D, vitamin D binding protein, vitamin D receptor levels and cardiac dysautonomia in patients with multiple sclerosis: a cross-sectional study
RESUMO A vitamina D é um hormônio esteroide pleiotrópico que modula o equilíbrio autonômico. Sua deficiência tem sido descrita como fator de risco ambiental para esclerose múltipla (EM). O objetivo deste estudo foi investigar os níveis séricos de vitamina D, proteína de ligação à vitamina D (VDBP) e receptor de vitamina D (VDR) e avaliar a disau

3. HEART RATE VARIABILITY IN TENNIS PLAYERS
RESUMO Introdução Alguns estudos sugerem que a modalidade esportiva tênis traz benefícios aos perfis antropométrico e metabólico de seus praticantes, reduzindo o risco de mortalidade de forma mais significante que outras modalidades esportivas. Além disso, as alterações na regulação autonômica cardiovascular têm sido evidenciadas como fator co

4. SEDENTARY LIFESTYLE IN ADOLESCENTS IS ASSOCIATED WITH IMPAIRMENT IN AUTONOMIC CARDIOVASCULAR MODULATION
RESUMO Introdução A prática regular de exercícios físicos ou o estilo de vida mais ativo são importantes na prevenção de doenças cardiovasculares, reduzindo não somente a mortalidade cardiovascular, mas também favorecendo a redução dos fatores de risco relacionados com essas doenças. Objetivo Avaliar a associação entre inatividade física

5. Familial history of hypertension-induced impairment on heart rate variability was not observed in strength-trained subjects
Family history of hypertension is an important predictive factor for hypertension and is associated with hemodynamic and autonomic abnormalities. Previous studies reported that strength training might reduce arterial blood pressure (AP), as well as improve heart rate variability (HRV). However, the benefits of strength training in the offspring of hypertensi

6. ACE gene dosage determines additional autonomic dysfunction and increases renal angiotensin II levels in diabetic mice
OBJECTIVES: The present study aimed to investigate cardiovascular autonomic modulation and angiotensin II (Ang II) activity in diabetic mice that were genetically engineered to harbor two or three copies of the angiotensin-converting enzyme gene. METHODS: Diabetic and non-diabetic mice harboring 2 or 3 copies of the angiotensin-converting enzyme gene were

7. Resting spontaneous baroreflex sensitivity and cardiac autonomic control in anabolic androgenic steroid users
OBJECTIVES: Misuse of anabolic androgenic steroids in athletes is a strategy used to enhance strength and skeletal muscle hypertrophy. However, its abuse leads to an imbalance in muscle sympathetic nerve activity, increased vascular resistance, and increased blood pressure. However, the mechanisms underlying these alterations are still unknown. Therefore, w

8. Neural mechanismsand post-exercise hypotension: The importance of experimental studies
Abstract A single bout of exercise can decrease blood pressure level in hypertensive individuals and this phenomenon is known as post-exercise hypotension (PEH). PEH is clinically important and reduces blood pressure after physical exercise in hypertensive subjects. This reduction has been attributed to autonomic mechanisms, e.g., reduced peripheral sympathe

9. Time course of changes in heart rate and blood pressure variability in rats with myocardial infarction
Our aim was to determine the time course of changes in autonomic balance in the acute (1 and 3 days), sub-acute (7 days) and chronic (28 days) phases of myocardial infarction (MI) in rats. Autonomic balance was assessed by temporal and spectral analyses of blood pressure variability (BPV) and heart rate variability (HRV). Pulsatile blood pressure (BP) record

10. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have

11. Correlation between heart rate variability and pulmonary function adjusted by confounding factors in healthy adults
The autonomic nervous system maintains homeostasis, which is the state of balance in the body. That balance can be determined simply and noninvasively by evaluating heart rate variability (HRV). However, independently of autonomic control of the heart, HRV can be influenced by other factors, such as respiratory parameters. Little is known about the relations

12. Cardiac autonomic responses during upper versus lower limb resistance exercise in healthy elderly men
Objective: To investigate the cardiac autonomic responses during upper versus lower limb discontinuous resistance exercise (RE) at different loads in healthy older men. Method: Ten volunteers (65±1.2 years) underwent the one-repetition maximum (1RM) test to determine the maximum load for the bench press and the leg press. Discontinuous RE was initiate
