Hypoxia-Induced Oxidative Stress Modulation with Physical Activity
Increased oxidative stress, defined as an imbalance between prooxidants and antioxidants, resulting in molecular damage and disruption of redox signaling, is associated with numerous pathophysiological processes and known to exacerbate chronic diseases. Prolonged systemic hypoxia, induced either by exposure to terrestrial altitude or a reduction in ambient O2 availability is known to elicit oxi...
متن کاملOxidative Stress and Physical Activity
The cells continuously produce free radicals and reactive oxygen species as a part of metabolic processes. Increased aerobic metabolism during exercise is a potential source of oxidative stress. Also, anaerobic physical activity and oxidative stress are interrelated because the intense anaerobic activity leads to damage proteins, lipids and nucleic acids in muscle cells and blood. Complex syste...
متن کاملHypoxia-Induced Oxidative Stress in Health Disorders
Chronic hypoxia has been shown to promote a large number of pathologies such as hypertension, cardiovascular and metabolic disorders, and respiratory diseases. The oxidative stress that occurs during intermittent or continuous cellular hypoxia is likely involved in all these diseases. Indeed, the reactive species were demonstrated to inhibit active substances, modulate the signaling of intracel...
متن کاملHypoxia-Induced Oxidative Stress in Ischemic Retinopathy
Oxidative stress plays a crucial role in the pathogenesis of retinal ischemia/hypoxia, a complication of ocular diseases such as diabetic retinopathy (DR) and retinopathy of prematurity (ROP). Oxidative stress refers to the imbalance between the production of reactive oxygen species (ROS) and the ability to scavenge these ROS by endogenous antioxidative systems. Free radicals and ROS are implic...
متن کاملHypoxia, Oxidative Stress and Fat
Metabolic disturbances in white adipose tissue in obese individuals contribute to the pathogenesis of insulin resistance and the development of type 2 diabetes mellitus. Impaired insulin action in adipocytes is associated with elevated lipolysis and increased free fatty acids leading to ectopic fat deposition in liver and skeletal muscle. Chronic adipose tissue hypoxia has been suggested to be ...
