Sympatho-Vagal Imbalance is Associated with Sarcopenia in Male Patients with Heart Failure

Arq. bras. cardiol; 112 (6), 2019
Abstract Background: Resting sympathetic hyperactivity and impaired parasympathetic reactivation after exercise have been described in patients with heart failure (HF). However, the association of these autonomic changes in patients with HF and sarcopenia is unknown. Objective: The aim of this study wa...

Efectividad de ejercicio físico intervalado de alta intensidad en las mejoras del fitness cardiovascular, muscular y composición corporal en adolescentes: una revisión

Rev. méd. Chile; 147 (2), 2019
This review analyzes the effects of high intensity interval training (HIIT) on muscle and cardiovascular fitness and body composition in teenagers. A search was carried out in international databases, finding 145 papers and selecting five for analysis. In all the reviewed manuscripts, peak oxygen uptake ...

Voluntary wheel running: patterns and physiological effects in mice

Braz. j. med. biol. res; 52 (1), 2019
Exercise can prevent and improve the pathophysiology of diseases and promote healthy aging. Thus, understanding the mechanisms that regulate the beneficial effects of exercise may lead to the development of new strategies to enhance quality of life and to counteract chronic diseases. Voluntary wheel runn...

Effects of natural aging and gender on pro-inflammatory markers

Braz. j. med. biol. res; 52 (9), 2019
The term inflammaging is now widely used to designate the inflammatory process of natural aging. During this process, cytokine balance is altered, presumably due to the loss of homeostasis, thus contributing to a greater predisposition to disease and exacerbation of chronic diseases. The aim of the study...

Asociación del sobrepeso y obesidad, consumo de oxígeno y calidad del sueño con los síntomas del intestino irritable en estudiantes universitarios de la UPNFM

INTRODUCCIÓN: El interés de este estudio fue establecer posibles asociaciones con el estado físico, calidad de sueño y consumo de oxígeno máximo (VO2máx) con los síntomas de la enfermedad del síndrome de Intestino Irritables (SII) en los estudiantes universitarios. MÉTODOS: La muestra f...

Validation of the two-minute step test in obese with comorbibities and morbidly obese patients

Braz. j. med. biol. res; 52 (9), 2019
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...

Effects of a high-intensity pulmonary rehabilitation program on the minute ventilation/carbon dioxide output slope during exercise in a cohort of patients with COPD undergoing lung resection for non-small cell lung cancer

J. bras. pneumol; 45 (6), 2019
ABSTRACT Objective: Preoperative functional evaluation is central to optimizing the identification of patients with non-small cell lung cancer (NSCLC) who are candidates for surgery. The minute ventilation/carbon dioxide output (VE/VCO2) slope has proven to be a predictor of surgical complications and m...

Intensity of physical exercise and its effect on functional capacity in COPD: systematic review and meta-analysis

J. bras. pneumol; 45 (6), 2019
ABSTRACT Objective: To evaluate the effects of high-intensity interval training (HIIT), in comparison with those of continuous exercise, on functional capacity and cardiovascular variables in patients with COPD, through a systematic review and meta-analysis of randomized controlled trials. Methods: We ...

A detailed comparison of oxygen uptake kinetics at a range of exercise intensities

Motriz (Online); 25 (1), 2019
Aim: The aim of this study was to comprehensively examine oxygen uptake (V̇O2) kinetics during cycling through mathematical modeling of the breath-by-breath gas exchange responses across eight conditions of unloaded cycling to moderate to high-intensity exercise. Methods: Following determination of G...

Modulación de marcadores de inflamación y estrés oxidativo en pacientes con diabetes tipo 1 y sobrepeso que participan en un programa de cambio de estilo de vida

Introduction: Reduction in the expression of inflammatory markers and oxidative stress associated with exercise will protect against cardiovascular complications in Diabetes Mellitus (DM). Aim: The aim of this study was evaluated cardiovascular fitness (VO2 Max), interleukin-6 (IL-6), monocyte chemo-attr...
