1. Heart rate turbulence assessed through ergometry after myocardial infarction: a feasibility study
ABSTRACT BACKGROUND: Coronary artery disease is an important cause of morbidity and mortality. The impact of ventricular arrhythmias with impaired cardiac vagal activity is one of the most recently studied prognostic factors. However, there are no studies evaluating the phenomenon of heart rate turbulence (HRT) during physical exertion. OBJECTIVE: To stu

2. Hepatic Elastography in the Assessment of Heart Failure: Where We Came from and Where We Are Going
Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

3. QT Interval Dispersion Behavior in Patients With and Without Obstructive Coronary Artery Disease Undergoing Exercise Test
Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

4. Effect of transcranial direct current stimulation on supramaximal intermittent exercise performance
Abstract Aim: Our purpose was to determine whether Transcranial Direct Current Stimulation (tDCS) improves performance in untrained individuals for supramaximal intermittent exercise. Methods: In a cross-over design, 11 healthy male subjects (26.8 ± 4.6 years) performed four Wingate trials after 20 minutes of anodal or sham tDCS over the left Insular Cort

5. O nível de condicionamento físico interfere nas respostas psicofisiológicas?
Resumo Objetivou-se avaliar se o nível de condicionamento físico interfere na resposta psicofisiológica durante a corrida. Quinze atletas (25, 3 ± 2, 4 anos) corredores de fundo (G1) e 15 indivíduos ativos (23, 1 ± 4, 3 anos) não atletas (G2) fizeram uma sessão de corrida de 80 min com intensidade controlada entre 75 e 85% da frequência cardíaca de

8. Spontaneous Left Anterior Descending Coronary Artery Dissection Requiring Coronary Artery Bypass Surgery
Abstract Introduction: Spontaneous coronary artery dissection is a sudden separation between the layers of a coronary artery wall, non-iatrogenic or trauma related, that has been recognized as an important cause of myocardial infarction. Objective: To report an emblematic case, in terms of angiographic images, clinical presentation and predisposing factors

9. Effect of salbutamol on the cardiovascular response in healthy subjects at rest, during physical exercise, and in recovery phase: a randomized, double-blind, crossover study
ABSTRACT Aim To evaluate the effect of the short-acting beta agonists (SABAs) salbutamol on cardiovascular response rest, exercise and recovery phase. Methods This study was conducted as a randomized, double-blind, placebo controlled, crossover study in 15 healthy adults, with a mean age of 30.2±6.6 years. Participants underwent a maximal effort test on t

11. A escala CR-10 de Borg é viável para quantificar a intensidade do exercício aeróbio em mulheres com síndrome fibromiálgica
RESUMO Pacientes com síndrome fibromiálgica (SFM) relatam elevados níveis de percepção subjetiva de esforço (PSE) em comparação com indivíduos saudáveis para a mesma intensidade de exercício; no entanto, a nosso conhecimento, nenhum estudo avaliou a PSE no limiar de anaerobiose ventilatório (LAV) para essa população. Este estudo buscou avaliar

12. Does the incremental shuttle walk test require maximal effort in young obese women?
Obesity is a chronic disease with a multifaceted treatment approach that includes nutritional counseling, structured exercise training, and increased daily physical activity. Increased body mass elicits higher cardiovascular, ventilatory and metabolic demands to varying degrees during exercise. With functional capacity assessment, this variability can be eva
