RESUMO Objetivo Verificar a variação dos parâmetros cardiorrespiratórios na alimentação de bebês cardiopatas. Método Estudo transversal controlado, realizado com bebês de 0 a 6 meses de idade, de ambos os gêneros, em um hospital de referência para cirurgia cardíaca pediátrica. Foram divi...
Cardiopulmonary fitness assessment is a valuable resource to obtain quantitative indicators of an individual's physical performance. The cardiopulmonary exercise test (CPX), considered the gold standard test for this evaluation, is costly and difficult to be accessed by the general population. In order t...

OBJECTIVES: To estimate the prevalence of exercise testing alterations in middle-aged women without symptoms of heart disease and to verify the associations of functional capacity and heart rate behavior during and after exercise with cardiovascular risk factors. METHODS: A cross-sectional study was con...
ABSTRACT The 30% maximal voluntary contraction protocol for isometric handgrip exercise is widely used to improve the cardiovascular system. However, it is unknown whether intensity modulation affects these responses. Objective: To analyze acute cardiovascular responses after isometric handgrip exercise ...

Aim:
The aim of the present study was to verify the agreement between the ventilatory method (VT) and the alternative method of heart rate deflection point (HRDP) in determining the anaerobic threshold (AT) during incremental treadmill test in dyslipidaemic patients.
Methods:
Twenty-seven dyslipidaemi...
El aleteo auricular (AA) con conducción auriculoventricular 1:1 es una condición de presentación infrecuente en la práctica clínica, se da debido a diversos factores entre los cuales los más importantes son la presencia de vías accesorias concomitantes o uso de ciertos medicamentos antiarrítmicos...
Aim: Heart rate variability threshold (HRVT) is a valid method to determine parasympathetic depression during an incremental exercise test (IET). However, HRVT is usually assessed using the last 60s of each 180s stage of an IET, resulting in longer and demotivating tests. This study aimed to evaluate th...
Aim: To verify the on and off heart rate (HR) and HR variability (HRV) kinetics during a high-load
aerobic exercise and a low-load aerobic exercise, with and without blood flow restriction (BFR). Methods: Fourteen
healthy male subjects performed three randomly assigned experimental sessions: 1) 10 minute...
Aims:
To investigate the early and late ischemic preconditioning (IPC) effect on the trained cyclists’ performance during incremental cycling test until exhaustion.
Methods:
Twenty-one male cyclists allocated to an IPC (2 x 5-min of blood flow occlusion at 50 mm Hg above systolic pressure followed +...
BACKGROUND: The Trendelenburg position (TP) has been empirically used to increase preload and thus cardiac output (CO). Transthoracic echocardiogram (TTE) is a noninvasive technique that estimates CO. We aimed to describe if the TP can improve CO. MATERIALS AND METHODS: We conducted a descriptive study i...
