Global Longitudinal Strain Predicts Poor Functional Capacity in Patients with Systolic Heart Failure

Arq. bras. cardiol; 113 (2), 2019
Abstract Background: Left ventricular global longitudinal strain value (GLS) can predict functional capacity in patients with preserved left ventricular ejection fraction (LVEF) heart failure (HF) and to assess prognosis in reduced LVEF HF. Objetive: Correlate GLS with parameters of Cardiopulmonary Exe...

Comparative Analysis of Direct and Indirect Methods for the Determination of Maximal Oxygen Uptake in Sedentary Young Adults

Maximal oxygen uptake is a powerful prognostic indicator and a reliable measure of physical conditioning. It can be measured directly by cardiopulmonary exercise testing (CPET) or indirectly by formulas derived from conventional protocols. Objective: We compared the VO2 max obtained by formula using exe...

Teste cardiopulmonar no diagnóstico de doença coronariana: acurácia da curva do pulso de oxigênio

A isquemia miocárdica induzida por esforço em níveis significativos interferiria no aumento no volume sistólico e levaria à deflexão da curva do PuO2. A alteração da resposta curvilínea do PuO2, que resulta em achatamento da curva, demonstraria redução do volume sistólico e/ou falha para aum...

Analysis of Methods for Evaluating the Functional State and Physical Fitness of Men and Women in The Second Period of Adulthood

Prensa méd. argent; 105 (4), 2019
Methods for evaluating the functional state of the body and physical fitness of men and women in the second period of adulthood have been analyzed in the article. The timely diagnosis of these indicators allows to optimally distribute exercises and adjust them to each trainee. Indicators of the functiona...

Association of flexibility with sociodemographic factors, physical activity, muscle strength, and aerobic fitness in adolescents from southern brazil

ABSTRACT Objective: To identify sociodemographic, physical activity, and physical fitness factors associated with flexibility. Methods: Cross-sectional study with 909 adolescents (486 girls) aged 14 to 19 years from the city of São José, Santa Catarina, Brazil. To evaluate flexibility, we used the ...

Predictive equations of maximum oxygen consumption by shuttle run test in children and adolescents: a systematic review

ABSTRACT Objective: To systematically review the literature as for the level of evidence of predictive equations of VO2peak through the 20-meter shuttle run test (20m-SRT) in children and adolescents. Data sources: Searches were conducted independently by two researchers, according to the procedures ...

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...

Fiabilidad de dos pruebas de velocidad de marcha de diferentes fases cronometradas e iguales fases no cronometradas en personas mayores que viven en la comunidad

Medwave; 19 (3), 2019
ANTECEDENTES La velocidad de la marcha es una medida rápida, económica y precisa para evaluar la capacidad funcional de las personas mayores, tanto saludables como con diferentes comorbilidades. Estudios previos han evaluado la velocidad de la marcha medida a lo largo de cursos de diferentes distancias...

Is a short-stage protocol during an incremental exercise test reliable for heart rate variability threshold analysis?

Motriz (Online); 25 (3), 2019
Aim: Heart rate variability threshold (HRVT) is a valid method to determine parasympathetic depression during an incremental exercise test (IET). However, HRVT is usually assessed using the last 60s of each 180s stage of an IET, resulting in longer and demotivating tests. This study aimed to evaluate th...

Football training session rises creatine kinase but does not impair performance

Motriz (Online); 25 (3), 2019
Aim: Determine the relationship between changes in oxidative stress markers, muscle damage, DOMS, and their relationship with performance in response to a session of football training during a 1-week recovery period of young football players. Methods: Nineteen young football players aged 16.7±1.0 yea...
