Vascular and ventilatory mechanical responses in three different stages of pulmonary development in the rabbit model of congenital diaphragmatic hernia

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To evaluate the vascular ventilatory response in different stages of lung development and to compare them to the neonates with congenital diaphragmatic hernia (CDH) in a rabbit model. Methods: New Zealand rabbits were divided into 8 groups (n=5): E25, E27, E30, and CDH. All groups wer...

Is cardiorespiratory optimal point measured during the maximal cardiopulmonary exercise test a relevant indicator of sports performance?

Maximal oxygen consumption (VO2max) and ventilatory threshold (VT) obtained during a cardiopulmonary exercise test (CPX) are used in the evaluation of athletes. However, the identification of these variables may sometimes be unreliable, which limits their use. In contrast, the cardiorespiratory optimal p...

Ponto Ótimo Cardiorrespiratório em Futebolistas Profissionais: Uma Nova Variável Submáxima do Exercício

O consumo máximo de oxigênio (VO2max) e o limiar anaeróbico (LA) obtidos no teste cardiopulmonar de exercício (TCPE) são utilizados na avaliação de atletas. Todavia, dificuldades na identificação e mensuração dessas variáveis dificultam sua utilização prática. O ponto ótimo cardiorrespira...

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.
