Assess the effects of exercise-training on resting arterial pressure and heart rate, placental fetuses morphologic alterations in pregnant spontaneously hypertensive rats (SHRs).Twenty SHRs and their respective control normotensive rats (WKY) were submitted or not to a swimming protocol during 9 weeks, resulting in four pregnant experimental groups: sedentary hypertensive (PSH), ...

The objective of this study was to investigate mechanisms of exercise-induced pulmonary hypertension in patients with congenital cardiac septal defects. This was a randomized, placebo controlled, crossover drug trial in a single national pediatric cardiology centre that performs congenital cardiac defect surgery. There were 14 patients with cardiac septal defects ...

BACKGROUND: /st>Disturbed breathing during sleep, with episodic upper airway obstruction, is frequent after major surgery. Ventilatory responses to hypercapnia and hypoxia during episodes of airway obstruction are difficult to investigate because the usual measure, that of ventilation, has been attenuated by the obstruction. We simulated the blood gas stimulus associated ...

Abstract Background: Recently, abdominal-breathing or diaphragmatic-breathing methods have increased in popularity. Little is known how abdominal breathing affects the circulatory system. This study was designed to determine the impact of the respiratory pattern on central venous flow using echocardiography. Methods: The superior vena cava (SVC) and inferior vena cava (IVC) ...

The aims of this study were: (i) to measure energy system contributions in maximal anaerobic running test (MART); and (ii) to verify any correlation between MART and maximal accumulated oxygen deficit (MAOD). Eleven members of the armed forces were recruited for this study. Participants performed MART and MAOD, both accomplished ...
