山东大学医学院病理生理学课件 hypoxia
A higher-than-average maximal oxygen consumption (VO2max), is closely associated with decreased morbidity and mortality and improved quality of life and acts as a marker of cardiorespiratory fitness. ...
Purpose: To compare hemoglobin mass (Hbmass) changes during an 18-d live high–train low (LHTL) altitude training camp in normobaric hypoxia (NH) and hypobaric hypoxia (HH). Methods: Twenty-eight well...
Purpose: Slight physiological differences between acute exposure in normobaric hypoxia (NH) and hypobaric hypoxia (HH) have been reported. Taken together, these differences suggest different physiolog...
Purpose: This study investigated the efficacy of an intermittent critical power (CP) model, termed the “work-balance” (W′BAL) model, during high-intensity exercise in hypoxia (HYPO). Methods: Eleven ...
Purpose: Physical exercise or hypoxic exposure influences hemorheology and acid–base homeostasis. Band 3 protein in erythrocytes modulates cells’ rheological properties and anion transport ability. Th...
天津医科大学病理生理学课件 Hypoxia.
Hypoxia is a condition in which an area of the body or a tissue is deprived of sufficient supply of oxygen. The lack of nutrients in a hypoxic tissue generally causes apoptosis but some cells are able...
Anyone working with highly trained athletes will be doubtful toward any intervention that increases exercise performance by 55% after six training sessions, as recently reported by Faiss et al. (1). T...
We read with interest the recently published work from Hoshikawa et al. (3) in which the authors perform a rigorous evaluation of various sleep measures, first during five nights’ stay in normoxia, an...
Purpose: The purpose of this study was to evaluate the effects of five nights’ sleep under normobaric hypoxia on ventilatory acclimatization and sleep quality. Methods: Seven men initially slept for ...
The purpose of this study was to determine whether acute hypoxia alters the deoxygenation level in vastus lateralis muscle during a 30 s Wingate test, and to compare the muscle deoxygenation level bet...
Purpose: To generate parametric images of tumor hypoxia in a tumor-bearing rat model using voxel-based compartmental analysis of dynamic fluorine-18 labeled misonidazole (18F-FMISO) microPET? images, ...
This study addresses the question of whether repeated acute exposure to hyperbaric oxygen, such as encountered in O2 diving, affects the peripheral oxygen chemosensors. Groups of nondivers, active O2 ...
Respiratory quotient (RQ) was used to assess the effectiveness of exercise interventions in shifting substrate utilisation. The body's RQ can be estimated non-invasively from the ratio of CO2 producti...
