BACKGROUND the assessment of functional capacity in patients with chronic obstructive pulmonary disease (COPD) has been performed by simple and easy to apply methods that mimic everyday activities, such as the Chester step test (TChester). OBJECTIVES to investigate whether TChester is able to differentiate functional capacity and the magnitude of cardiorespiratory response of patients with CO...

This study examined the effect of acute hypoxic and hypercapnic cardiorespiratory stimuli, superimposed on existing cardiorespiratory disturbances in tambaqui. In their natural habitat, these fish often encounter periods of hypoxic hypercapnia that can be acutely exacerbated by water turnover. Tambaqui were exposed to periods of normoxia, hypoxia, hyperoxia and hypercapnia during which, externa...

BACKGROUND It is being increasingly recognised that reduced cardiorespiratory fitness is associated with poorer outcomes after major surgery. Exercise limitation and reduced aerobic capacity are common in people with end-stage liver disease. There is limited evidence about the role of exercise therapy in the management of primary biliary cirrhosis (PBC) and no studies have looked at the effect ...

BACKGROUND AND DESIGN Few studies have investigated the association between maximal cardiorespiratory capacity (fitness) and the clustered cardiovascular disease (CVD) risk in children and youth from culturally diverse countries. This cross-sectional study examined the association between fitness and clustered CVD risk in children and adolescents from three European countries. METHODS Partici...

Cardiorespiratory fitness (aerobic exercise capacity) is one of the most important prerequisites for successful aging in human beings and depends on adequate oxygen transport by the respiratory and circulatory systems from environmental air to the working muscles and the efficient utilization of oxygen by the mitochondria. A linear dose-response relation between aerobic exercise capacity, morbi...

Background. A respiratory gymnastics program introduced in subjects with essential arterial hypertension is assumed to improve their cardiorespiratory parameters. Also, respiratory gymnastics could increase the exercise capacity of hypertensive persons. Aims. Designing a respiratory gymnastics program applied to subjects with essential arterial hypertension, which can improve their blood pressu...
