1. Tai Chi exercise and functional electrical stimulation of lower limb muscles for rehabilitation in older adults with chronic systolic heart failure: a non-randomized clinical trial
Exercise-based training decreases hospitalizations in heart failure patients but such patients have exercise intolerance. The objectives of the study were to evaluate the effect of 12 weeks of Tai Chi exercise and lower limb muscles' functional electrical stimulation in older chronic heart failure adults. A total of 1,084 older adults with chronic systolic h

2. Hemodynamic, Metabolic and Ventilatory Responses to Exercise in Adults with Congenital Heart Disease
Abstract Background: Congenital heart disease in adults shares some features with heart failure (HF), including exercise intolerance, ventilatory inefficiency, inflammatory and neurohormonal activation, cardiac arrhythmias and myocardial fibrosis. Over the last years, cardiopulmonary exercise test has gained importance in the diagnostic and prognostic evalu

4. Nitrogen single-breath washout test for evaluating exercise tolerance and quality of life in patients with chronic obstructive pulmonary disease
Pulmonary function tests (PFTs) traditionally used in clinical practice do not accurately predict exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess whether the nitrogen single-breath washout (N2SBW) test explains exercise intolerance and poor quality of life in stable COPD patients. This c

5. Relationship between ventilation heterogeneity and exercise intolerance in adults with sickle cell anemia
Sickle cell anemia (SCA) causes dysfunction of multiple organs, with pulmonary involvement as a major cause of mortality. Recently, there has been growing interest in the nitrogen single-breath washout (N2SBW) test, which is able to detect ventilation heterogeneity and small airway disease when the results of other pulmonary function tests (PFTs) are still n

6. Exercise training on cardiovascular diseases: Role of animal models in the elucidation of the mechanisms
Abstract Cardiovascular diseases, which include hypertension, coronary artery disease/myocardial infarction and heart failure, are one of the major causes of disability and death worldwide. On the other hand, physical exercise acts in the preventionand treatment of these conditions. In fact, several experiments performed in human beings have demonstrated the

7. Perception of effort monitors internal load during compounded circuit training
Abstract The aim of this study was to determine if rating of perceived exertion (RPE) could be used to monitor the internal load during compounded circuit training (CCT) sessions in women. Thirteen young adults women performed three sessions of CCT varying the intensity according to participants' maximum heart rate (50, 70 and 90%HRmax). Throughout the main

8. Effects of exercise and metformin on the prevention of glucose intolerance: a comparative study
We aimed to evaluate the effects of aerobic exercise training (4 days) and metformin exposure on acute glucose intolerance after dexamethasone treatment in rats. Forty-two adult male Wistar rats (8 weeks old) were divided randomly into four groups: sedentary control (SCT), sedentary dexamethasone-treated (SDX), training dexamethasone-treated (DPE), and dexam

9. Effect of L-carnitine on exercise performance in patients with mitochondrial myopathy
Exercise intolerance due to impaired oxidative metabolism is a prominent symptom in patients with mitochondrial myopathy (MM), but it is still uncertain whether L-carnitine supplementation is beneficial for patients with MM. The aim of our study was to investigate the effects of L-carnitine on exercise performance in MM. Twelve MM subjects (mean age±SD=35.4

10. Relação entre estrutura e função muscular de membros superiores em pacientes com doença pulmonar obstrutiva crônica. / Relation between structure and muscular function of superior members in patients with pulmonary illness obstrutiva chronicle.
Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation that is not fully reversible. COPD is also characterized by exercise intolerance which can be caused by multiple factors. Quadriceps femoris is the most commonly muscle studied in skeletal muscle dysfunction syndrome in COPD. However, it ha

11. Oxygen uptake and skeletal muscle reoxygenation kinetics in high-intensity exercise recovery of patients with mitochondrial myopathy: Implications on the mechanisms of exercise intolerance. / Avaliação das cinéticas do consumo de oxigênio e da reoxigenação muscular esquelética na recuperação do exercício de alta intensidade em pacientes com miopatia mitocondrial: Implicações sobre os mecanismos de intolerância ao exercício
Introdução: Os pacientes com Miopatia Mitocondrial (MM) e Oftalmoplegia Externa Progressiva (OEP) apresentam disfunção na cadeia respiratória com incapacidade de aumentar a extração de oxigênio muscular e sintetizar ATP aerobicamente, levando à intolerância ao esforço e lentificação da cinética do O2. Quando a extração de oxigênio é comprom

12. Neuromuscular electrical stimulation improves exercise tolerance in chronic obstructive pulmonary disease patients with better preserved fat-free mass
BACKGROUND: High-frequency neuromuscular electrical stimulation increases exercise tolerance in patients with advanced chronic obstructive pulmonary disease (COPD patients). However, it is conceivable that its benefits are more prominent in patients with better-preserved peripheral muscle function and structure. OBJECTIVE: To investigate the effects of high-
