1. 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.

5. Efeitos agudos da ingestão de cafeína no desempenho em teste específico de pádel
Resumo Objetivou-se mensurar os efeitos da cafeína em teste de precisão de voleio específico (TPVE). Após 30 min da ingesta de 6mg•kg–1 de cafeína (CAF) ou placebo (PLA), 12 atletas fizeram duas sessões de treino de 45 min. Mediu-se resistência de preensão manual (RPM), foram registradas frequência cardíaca (FC) e percepção subjetiva de esfor

6. SODIUM BICARBONATE SUPPLEMENTATION IMPROVES PERFORMANCE IN ISOMETRIC FATIGUE PROTOCOL
RESUMO Introdução: A suplementação de bicarbonato de sódio (NaHCO3) tem demonstrado atenuar a fadiga e melhorar o desempenho do exercício de alta intensidade, mas os efeitos sobre a manutenção de contrações isométricas são pouco claros. Objetivo: Investigar o efeito do NaHCO3 no desempenho de indivíduos submetidos ao protocolo de fadiga em exe

7. Carbohydrate mouth rinse reduces rating of perceived exertion but does not affect performance and energy systems contribution during a high-intensity exercise
ABSTRACT Aim The study aimed to verify the effect of carbohydrate (CHO) mouth rinse on time to exhaustion, energy systems contribution and rating of perceived exertion (RPE) during a high-intensity exercise. Methods Fourteen men performed an incremental exercise test to determine their maximal oxygen uptake and peak power output (PPO) and two time-to-exhau

8. Acute effects of maximal isometric muscle action of the elbow extensors on contralateral dynamic task of the elbow flexors: a pilot study
ABSTRACT Aim the aim was to investigate the influence of a maximal isometric muscle action of the elbow extensors on the contralateral dynamic task of the elbow flexors. Methods Seventeen recreationally trained men (23.3 ± 4.9 yrs, BMI: 24.8 ± 2.2 Kg/m²) underwent two randomized different testing sessions separated by one week. In the control session (C

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. Effects of a 4-week high-intensity interval training on pacing during 5-km running trial
This study analyzed the influence of a 4-week high-intensity interval training on the pacing strategy adopted by runners during a 5-km running trial. Sixteen male recreational long-distance runners were randomly assigned to a control group (CON, n=8) or a high-intensity interval training group (HIIT, n=8). The HIIT group performed high-intensity interval-tra

12. Evaluating respiratory musculature, quality of life, anxiety, and depression among patients with indeterminate chronic Chagas disease and symptoms of pulmonary hypertension
Abstract INTRODUCTION: Chagas disease (CD) is progressive and incapacitating, especially when cardiopulmonary function is affected. For example, respiratory muscle weakness can cause dyspnea upon exertion and fatigue, which may be exacerbated when it is associated with pulmonary hypertension (PH). The present study aimed to evaluate respiratory musculature
