Intermittent hypoxia: cell to system.
This symposium was organized to present research dealing with the effects of intermittent hypoxia on cardiorespiratory systems and cellular mechanisms. The pattern of neural impulse activity has been shown to be critical in the induction of genes in neuronal cells and involves distinct signaling pathways. Mechanisms associated with different patterns of intermittent hypoxia might share similar ...
متن کاملRole of nitric oxide in cardiovascular adaptation to intermittent hypoxia.
Hypoxia is one of the most frequently encountered stresses in health and disease. The duration, frequency, and severity of hypoxic episodes are critical factors determining whether hypoxia is beneficial or harmful. Adaptation to intermittent hypoxia has been demonstrated to confer cardiovascular protection against more severe and sustained hypoxia, and, moreover, to protect against other stress...
متن کاملMuscle fiber specific antioxidative system adaptation to swim training in rats: influence of intermittent hypoxia.
The aim of the present study was to examine the influence of intermittent hypoxia at rest and in combination with long-term high-intensity swimming exercise on lipid peroxidation and antioxidant defense system adaptation in skeletal muscles differing in fiber type composition. High-intensity chronic exercise was performed as swimming training with load that corresponded to ~ 75 % VO2max (30 min...
متن کاملHigh-intensity kayak performance after adaptation to intermittent hypoxia.
CONTEXT Live-high train-low altitude training produces worthwhile gains in performance for endurance athletes, but the benefits of adaptation to various forms of artificial altitude are less clear. PURPOSE To quantify the effects of intermittent hypoxic exposure on kayak performance. METHODS In a crossover design with a 6-week washout, we randomized 10 subelite male sprint kayak paddlers to...
متن کاملAdaptation to Nocturnal Intermittent Hypoxia in Sleep-Disordered Breathing: 2,3 Diphosphoglycerate Levels: A Preliminary Study
The oxygenation of tissues depends on several factors such as blood flow, oxygen carrying capacity of the blood and the affinity of the hemoglobin for oxygen. Patients with an abnormality of one of these factors depend on adjustment in one or more other factors in order to maintain optimal tissue oxygenation. For instance, people who reside at high altitudes have two available modes of compensa...
