Entrenamiento físico de alta intensidad en maratonistas produce mayor remodelado cardíaco y reduce respuesta de estrés oxidativo

Rev. chil. cardiol; 37 (2), 2018
Resumen: Introducción: El ejercicio físico reduce la mortalidad cardiovascular y genera remodelado cardíaco. Altas cargas de entrenamiento pueden generar remodelado cardíaco adverso. Biomarcadores (BMC) de inflamación Interleukina 6 (IL-6) y de estrés oxidativo Malondialdehído (MDA), potencialmen...

Effects of high-intensity inspiratory muscle training associated with aerobic exercise in patients undergoing cabg: randomized clinical trial

Abstract Objective: Evaluate the interaction between high-intensity inspiratory muscle training (IMT) and aerobic exercise on physical capacity, respiratory muscle strength, peripheral muscle strength, and quality of life of patients who underwent coronary artery bypass grafting (CABG). Methods: Twenty...

Oficina de expressividade vocal para pessoas idosas

A voz, nada mais é do que a necessidade de se comunicar e, quando esta encontra-se comprometida passa a interferir nas relações sociais, no quadro emocional e interação com outros sujeitos. Assim, sabendo-se da realidade do que seja uma pessoa idosa isolada e o quanto o uso da expressividade vocal p...

Ejercicio físico en pacientes con diabetes e hipertensión: prevalencia de respondedores y no respondedores para mejorar factores de riesgo cardiometabólicos

Rev. méd. Chile; 146 (6), 2018
Background: There is a wide interindividual variability in the response to a period of exercise training. The science have reported that a minimum of participants could be non-responders for improving different health-related outcomes after training. Aim: To compare the effects of a 6-weeks exercise pro...

Combatiendo el metabolismo de las células cancerosas mediante la activación de SIRT3 y el ejercicio físico

Rev. méd. Chile; 146 (6), 2018
One of the main features of cancer is the high rate of cell proliferation and growth. To do this, cancer cells need to redirect their metabolism mainly towards anaerobic glycolysis and an increased mitochondrial glutamine energy metabolism. Sirtuins are cellular proteins with regulatory functions on meta...

Hipertensión arterial pulmonar: el entrenamiento físico como complemento de la terapia farmacológica

Rev. méd. Chile; 146 (5), 2018
Cardiopulmonary rehabilitation is a promising therapy for Pulmonary arterial hypertension (PAH) whose survival does not exceed 65% at five years. We performed a literature search about rehabilitation on PAH in MEDLINE, LILACS and COCHRANE databases, considering articles from 2005 to 2017. Fifteen article...

Safety and Efficacy of Aerobic Exercise Training Associated to Non-Invasive Ventilation in Patients with Acute Heart Failure

Arq. bras. cardiol; 110 (5), 2018
Abstract Background: Exercise training (ET) improves functional capacity in chronic heart failure (HF). However, ET effects in acute HF are unknown. Objective: To investigate the effects of ET alone or combined with noninvasive ventilation (NIV) compared with standard medical treatment during hospitali...

Influence of Aerobic Training on The Mechanics of Ventricular Contraction After Acute Myocardial Infarction: A Pilot Study

Arq. bras. cardiol; 110 (4), 2018
Abstract The study of myocardial contractility, based on the new anatomical concepts that govern cardiac mechanics, represents a promising strategy of analysis of myocardial adaptations related to physical training in the context of post-infarction. We investigated the influence of aerobic training on ph...

Moderate Continuous Aerobic Exercise Training Improves Cardiomyocyte Contractility in Β1 Adrenergic Receptor Knockout Mice

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: The lack of cardiac β1-adrenergic receptors (β1-AR) negatively affects the regulation of both cardiac inotropy and lusitropy, leading, in the long term, to heart failure (HF). Moderate-intensity aerobic exercise (MCAE) is recommended as an adjunctive therapy for patients w...

Exercise Training Attenuates Sympathetic Activity and Improves Morphometry of Splenic Arterioles in Spontaneously Hipertensive Rats

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Alterations in the structure of resistance vessels contribute to elevated systemic vascular resistance in hypertension and are linked to sympathetic hyperactivity and related lesions in target organs. Objective: To assess the effects of exercise training on hemodynamic and autonomi...
