The pattern and timing of breathing during incremental exercise: a normative study
(European Respiratory Soc Journals Ltd, 2003-03-01)
Clinical evaluation of the pattern and timing of breathing during submaximal exercise can be valuable for the identification of the mechanical ventilatory consequences of different disease processes and for assessing the ...
Assessment of functional impairment after knee anterior cruciate ligament reconstruction using cardiorespiratory parameters: a cross-sectional study
(Biomed Central Ltd, 2014-05-20)
Background: A dynamic sub-maximum exercise with the same absolute intensity, performed with different muscle groups, may present exacerbated cardiorespiratory responses. Therefore, cardiorespiratory responses to unilateral ...
Hypercarbic cardiorespiratory reflexes in the facultative air-breathing fish jeju (Hoplerythrinus unitaeniatus): the role of branchial CO2 chemoreceptors
(Company of Biologists Ltd, 2010-08-15)
The aim of the present study was to determine the roles that externally versus internally oriented CO2/H+-sensitive chemoreceptors might play in promoting cardiorespiratory responses to environmental hypercarbia in the ...
Evidence for a respiratory component, similar to mammalian respiratory sinus arrhythmia, in the heart rate variability signal from the rattlesnake, Crotalus durissus terrificus
(Company of Biologists Ltd, 2006-07-15)
Autonomic control of heart rate variability and the central location of vagal preganglionic neurones (VPN) were examined in the rattlesnake ( Crotalus durissus terrificus), in order to determine whether respiratory sinus ...
Regulation of ventilation in the caiman (Caiman latirostris): effects of inspired CO2 on pulmonary and upper airway chemoreceptors
(Springer, 2006-02-01)
In order to study the relative roles of receptors in the upper airways, lungs and systemic circulation in modulating the ventilatory response of caiman (Caiman latirostris) to inhaled CO2, gas mixtures of varying concentrations ...
Cardiorespiratory responses to hypoxia in the African catfish, Clarias gariepinus (Burchell 1822), an air-breathing fish
(Springer Heidelberg, 2011-10-01)
The African catfish, Clarias gariepinus, possesses a pair of suprabranchial chambers located in the dorsal-posterior part of the branchial cavity having extensions from the upper parts of the second and fourth gill arches, ...
Influência das variáveis antropométricas nas respostas cardiorrespiratórias de crianças durante o esforço
(Universidade Federal de Santa Catarina, 2011-10-01)
O objetivo deste estudo foi verificar a influência das diferentes dimensões corporais de meninos de 11 a 13 anos de idade, nas respostas cardiorrespiratórias, ao longo dos estágios de um teste incremental de esforço máximo ...
