Mental fatigue does not affect heart rate recovery but impairs performance in handball players

Rev. bras. med. esporte; 24 (5), 2018
INTRODUCTION: This study involved an analysis of the impact of mental fatigue on heart rate recovery (HRR), subjective measures of fatigue and intermittent running performance in handball players. OBJECTIVE: This study was aimed at (1) examining the effects of an induced state of mental fatigue on the ae...

Dor torácica na sala de emergência: quem fica e quem pode ser liberado?

A dor torácica aguda é um sintoma muito frequente nas unidades de emergência, constituindo-se em um possível sinal de alerta para as doenças com risco iminente de morte. Como a maioria desses pacientes é internada para avaliação de uma possível síndrome coronariana aguda, isso gera um custo hos...

Six-minute walk distance and survival time in patients with idiopathic pulmonary fibrosis in Brazil

J. bras. pneumol; 44 (4), 2018
ABSTRACT Objective: To determine the cut-off point for the six-minute walk distance (6MWD) that indicates lower survival time in patients with idiopathic pulmonary fibrosis (IPF) in Brazil. Methods: This was retrospective study carried out in two referral centers for IPF. The 6MWT was performed twice, ...

Ecuación para predecir el consumo máximo de oxígeno a partir de la prueba de caminata de seis minutos en jóvenes sanos

Rev. méd. Chile; 146 (7), 2018
Background: The six-minute walk test (SMWT) is an easy-to-use test that measures walking distance. Aim: To elaborate an equation to estimate the maximum oxygen consumption (VO2 max) using the results of the SMWT. Material and Methods: Forty men and 40 women aged 22.5 ± 2 years, underwent a SMWT to mea...

Monitorização hemodinâmica em emergência. Visão do fisioterapeuta: fisiologia aos efeitos da ventilação mecânica

Em diversas situações de emergência cardiológica, a tomada de decisão rápida a beira leito deve estar bem fundamentada para melhor eficácia terapêutica e baseada no conhecimento fisiológico e fisiopatológico da disfunção cardíaca que associada com a adequada monitorização hemodinâmica do...

Exercício físico após infarto agudo do miocárdio: segurança durante o exercício

Atualmente, os benefícios da reabilitação cardíaca baseada em exercícios para pacientes após IAM são indiscutíveis a longo prazo. Porém, as sessões de exercício físico aumentam acentuadamente o risco de eventos cardiovasculares através dos mecanismos cardíacos, autonômicos, inflamatórios...

Performances on the Timed Up and Go Test and subtasks between fallers and non-fallers in older adults with cognitive impairment

Arq. neuropsiquiatr; 76 (6), 2018
ABSTRACT This work aimed to compare performances on the Timed Up and Go (TUG) test and its subtasks between faller and non-faller older adults with mild cognitive impairment (MCI) and mild Alzheimer's disease (AD). A prospective study was conducted, with 38 older adults with MCI and 37 with mild AD. Part...

Reference values for the six-minute pegboard and ring test in healthy adults in Brazil

J. bras. pneumol; 44 (3), 2018
ABSTRACT Objective: To determine reference values for the six-minute pegboard and ring test (6PBRT) in healthy adults in Brazil, correlating the results with arm length, circumference of the upper arm/forearm of the dominant arm, and the level of physical activity. Methods: The participants (all volunt...

Association of oscillatory ventilation during cardiopulmonary test to clinical and functional variables of chronic heart failure patients

Abstract Objective: The aim of this study is to characterize the presence of exercise oscillatory ventilation (EOV) and to relate it with other cardiopulmonary exercise test (CET) responses and clinical variables. Methods: Forty-six male patients (age: 53.1±13.6 years old; left ventricular ejection fr...

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...
