Muscle oxygenation of the quadriceps and gastrocnemius during maximal aerobic effort

Rev. bras. med. esporte; 27 (2), 2021
ABSTRACT Introduction: Near infrared spectroscopy (NIRS) is a non-invasive technique that is used in the assessment of tissue oxygenation and the monitoring of physical activity. Objective: To determine the influence of sexual, anthropometric and ergospirometric factors on muscle oxygenation of the qua...

Exercise tests in Chagas cardiomyopathy: an overview of functional evaluation, prognostic significance, and current challenges

Abstract Patients with Chagas cardiomyopathy (ChC) usually progress with fatigue and dyspnea. Exercise tests are valuable for the functional evaluation of these patients. However, information about the applicability of the exercise tests is scattered, and no studies have systematically reviewed the resul...

RESUMO Objetivo Verificar se existem diferenças em pacientes com doença pulmonar obstrutiva crônica (DPOC) fenótipos exacerbador e não exacerbador submetidos a um programa de reabilitação pulmonar (PRP). Métodos Estudo retrospectivo de vida real que incluiu pacientes com DPOC da rede pública d...

Qual o melhor protocolo e ponto de corte no teste 4-metre gait speed para discriminar capacidade de exercício na Doença Pulmonar Obstrutiva Crônica?

J. bras. pneumol; 46 (6), 2020
RESUMO Objetivo Verificar o poder discriminativo e o ponto de corte de diferentes protocolos do teste 4-metre gait speed (4MGS) para identificar capacidade de exercício preservada ou reduzida no teste de caminhada de 6 minutos (TC6min) em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC); compa...

Effects of high- and moderate-intensity exercise on central hemodynamic and oxygen uptake recovery kinetics in CHF-COPD overlap

Braz. j. med. biol. res; 53 (3), 2020
The oxygen uptake (V˙O2) kinetics during onset of and recovery from exercise have been shown to provide valuable parameters regarding functional capacity of both chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients. To investigate the influence of comorbidity of COPD...

Construct validity and reproducibility of the six-minute step test in subjects with obstructive sleep apnea treated with continuous positive airway pressure

J. bras. pneumol; 46 (3), 2020
ABSTRACT Objective: To evaluate the construct validity and reproducibility of the six-minute step test (6MST) in individuals with obstructive sleep apnea (OSA) treated with continuous positive airway pressure (CPAP). Methods: We evaluated 48 volunteers diagnosed with OSA and treated with CPAP for at le...

Effect of an interdisciplinary intervention with motivational approach on exercise capacity in obese adolescents: a randomized controlled clinical trial

ABSTRACT Objective To evaluate the effect of an interdisciplinary intervention with a motivational approach on exercise capacity and usual physical activity levels in overweight and obese adolescents. Methods This is a randomized, controlled clinical trial with single blinding of subjects. Adolescent...

Associação da fadiga com capacidade do exercício em pacientes hepatopatas crônicos candidatos a transplante hepático

Arq. gastroenterol; 56 (3), 2019
ABSTRACT BACKGROUND: Fatigue is highly prevalent in end stage liver disease, the studies about its association with exercise capacity in cirrhotic patients before liver are scarse. OBJECTIVE: In this study, we evaluated fatigue in 95 in end stage liver disease patients awaiting transplantation, compa...

Influence of obesity in pulmonary function and exercise tolerance in obese women with obstructive sleep apnea

ABSTRACT Objective: To evaluate the influence of obesity on pulmonary function and exercise tolerance in women with obstructive sleep apnea (OSA). Subjects and methods: A descriptive analytic cross- sectional study was carried out. Thirty-nine (39) sedentary climacteric women, aged 45 to 60 years, were...

Ventilation distribution as a contributor to the functional exercise capacity in patients with systemic sclerosis-associated interstitial lung disease without pulmonary hypertension

Braz. j. med. biol. res; 52 (8), 2019
Phenotypic differences have been described between patients with systemic sclerosis (SSc)-associated interstitial lung disease (ILD) and SSc-associated pulmonary hypertension, including performance differences in the 6-min walk test (6MWT). Moreover, the correlations between the 6MWT and traditional pulm...
