Exercise intensity optimization for men with high cardiorespiratory fitness
(TAYLOR & FRANCIS LTD, 2011)
Exercise intensity is a key parameter for exercise prescription but the optimal range for individuals with high cardiorespiratory fitness is unknown. The aims of this study were (1) to determine optimal heart rate ranges ...
Chronic intermittent hypoxia enhances cat chemosensory and ventilatory responses to hypoxia
The carotid body (CB) chemoreceptors may play an important role in the enhanced hypoxic ventilatory response induced by chronic intermittent hypoxia (CIH). We studied the effects of cyclic hypoxic episodes of short duration ...
Age, invasive ventilatory support and outcomes in elderly patients admitted to intensive care units
(OXFORD UNIV PRESS, 2009)
Objective: to determine the relationship between age and in-hospital mortality of elderly patients, admitted to ICU, requiring and not requiring invasive ventilatory support. Design: prospective observational cohort study ...
Ventilatory compensation of the alkaline tide during digestion in the snake Boa constrictor
(Company of Biologists Ltd, 2004-03-01)
The increased metabolic rate during digestion is associated with changes in arterial acid-base parameters that are caused by gastric acid secretion (the 'alkaline tide'). Net transfer of HCl to the stomach lumen causes an ...
Ventilatory frequency of Nile tilapia subjected to different stressors
Ventilatory frequency (VF) was investigated in the fish Nile tilapia, Oreochromis niloticus, subjected to confinement, electroshock or social stressor. Fish were allowed to acclimatize to tank conditions for 10 days (1 ...
Chronic phenytoin treatment increases basal ventilation but reduces peripheral ventilatory drive in the anesthetized rat
The hypoxic ventilatory response (HVR) in rats depends on the carotid body (CB) chemoreceptors. The acute blockage of the persistent Na+ current (INaP) in rats reduces the CB chemosensory discharge, the basal ventilation ...
Effects of 12-week overground walking training at ventilatory threshold velocity in type 2 diabetic women
(Elsevier Ireland LtdClareIrlanda, 2011)
AGONISTIC PROFILE AND METABOLISM IN ALEVINS OF THE NILE TILAPIA
(Elsevier B.V., 1995-01-01)
Metabolic differences derived from social stress usually show data with high variance that may hinder the finding of important differences. Since such high variance may be caused by agonistic variability occurring during ...
