1. Evaluation of respiratory dynamics by volumetric capnography during submaximal exercise protocol of six minutes on treadmill in cystic fibrosis patients
Resumo Objetivos: A capnografia volumétrica fornece o padrão de eliminação do CO2, pelo volume expirado por ciclo respiratório e avalia o comprometimento pulmonar. O objetivo do estudo foi avaliar a dinâmica respiratória de indivíduos controles saudáveis e em indivíduos com fibrose cística, em um protocolo de exercício submáximo por seis minuto

2. Use of cardiopulmonary exercise testing to assess early ventilatory changes related to occupational particulate matter
Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive enough to show abnormalities before extensive damage, as seen in restrictive lung diseases. Therefore, we hypothesized that cardiopulmonary ex

3. Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS
OBJECTIVE: The purpose of this study was to compare aerobic function [anaerobic threshold (%VO2-AT), respiratory compensation point (%VO2-RCP) and peak oxygen uptake (VO2peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile

4. Efeito da correção cirúrgica nas variáveis do teste cardiopulmonar de exercício em pacientes com insuficiência mitral crônica. / Effect of surgical correction on cardiopulmonary exercise testing in patients with organic mitral regurgitation.
Introduction: Chronic organic Mitral Regurgitation (MR) has a complex physiopathology. The symptoms of heart failure and functional capacity worsening may appear too late, when a left ventricle (LV) contractile dysfunction already exists. The cardiopulmonary exercise testing (CPET) may objectively assess the functional capacity and helps in the medical condu

5. The slope of the oxygen pulse curve does not depend on the maximal heart rate in elite soccer players
INTRODUCTION: It is unknown whether an extremely high heart rate can affect oxygen pulse profile during progressive maximal exercise in healthy subjects. OBJECTIVE: Our aim was to compare relative oxygen pulse (adjusted for body weight) curves in athletes at their maximal heart rate during treadmill cardiopulmonary exercise testing. METHODS: A total of 180 e

6. Determinação das zonas de transição metabólica durante a corrida mediante os limiares de variabilidade da frequência cardíaca / Determination of transition metabolic zones during running using hert rate variability thresholds
The aim of the present study was to obtain evidences of validity and reliability of the thresholds of heart rate variability (HRV). Nineteen male subjects, healthy and runners (30,4 ± 4,1 years; 175,9 ± 6,4 cm; 74,3 ± 8,5 kg) performed a progressive maximal test on a treadmill with initial velocity 5 km.h-1 e increases of 1 km.h-1 every 3 minutes (1% slop

7. Analysis of physiological responses in women undergoing different protocols of treadmill inclinations / Análise das respostas fisiológicas em mulheres submetidas a diferentes protocolos de inclinação na esteira
A caminhada e a corrida são formas de exercício físico que promovem mudanças no estilo de vida, mas, existem muitas controvérsias dos possíveis benefícios e riscos a respeito da caminhada ou corrida quando realizada em diferentes inclinações. O presente estudo teve como objetivo determinar o limiar anaeróbio bem como avaliar e comparar as respostas

8. Inverse correlation between testosterone and ventricle ejection fraction, hemodynamics and exercise capacity in heart failure patients with erectile dysfunction
BACKGROUND: Neurohormonal activation and abnormalities in growth hormone and testosterone concentrations have been reported in heart failure (HF). Erectile dysfunction(ED) is common in these patients and contributes to a low quality of life. No data are known regarding the correlation between testosterone and hemodynamics, exercise capacity and cardiac funct

9. The relationship between heart rate reserve and oxygen uptake reserve in heart failure patients on optimized and non-optimized beta-blocker therapy
BACKGROUND: The relationship between the percentage of oxygen consumption reserve and percentage of heart rate reserve in heart failure patients either on non-optimized or off beta-blocker therapy is known to be unreliable. The aim of this study was to evaluate the relationship between the percentage of oxygen consumption reserve and percentage of heart rate

10. Reproducibility of the self-controlled six-minute walking test in heart failure patients
INTRODUCTION: The six-minute walk test (6WT) has been proposed to be a submaximal test, but could actually demand a high level of exercise intensity from the patient, expressed by a respiratory quotient >1.0, following the guideline recommendations. Standardizing the 6WT using the Borg scale was proposed to make sure that all patients undergo a submaximal wa

11. Acute effects of a single dose of phosphodiesterase type 5 inhibitor (sildenafil) on systemic arterial blood pressure during and after exercise in heart transplant recipients. / Efeito agudo do inibidor da fosfodiesterase tipo 5 (sildenafil) na pressão sanguínea arterial durante e após exercício em pacientes submetidos a transplante cardíaco
Background: Systemic hypertension (SH) can be associated with a decrease in endothelium-dependent nitric oxide (NO). Sildenafil determines increment in cyclic guanosine monophosphate (cGMP) that a mediator of NO. However, little is known about the effects of PDE5 inhibition on 24-hour ambulatory (ABP) and exercise blood pressure, noreprinephrine (Nor) and ex

12. Treino em esteira com suporte parcial de peso associado à estimulação elétrica funcional melhora a marcha de hemiparéticos crônicos e efeitos da inclinação da esteira na marcha de sujeitos hemiparéticos.
The purpose of this study was to evaluate the effect of the combined use of functional electrical stimulation (FES) and treadmill training with body weight support (BWS) in walking functions and voluntary limb control in chronic hemiparetic patients. Eight hemiparetic individuals (mean age, 56.6 10.26 years) were evaluated in the present clinical trial. The
