Acute exercise markedly increases blood oxidative stress in boys and girls
(2007)This study investigated the effect of an acute swimming protocol on selected blood redox status indices in trained children. Eleven boys and 11 girls (aged 9-11 y) swam 12 bouts of 50 m at a pace corresponding to 70%-75% ... -
Comparison of the blood redox status between long-distance and short-distance runners
(2006)Exercise increases the production of reactive oxygen species, which may damage a number of cell constituents. Organisms have developed a sophisticated antioxidant system for protection against reactive oxygen species. Our ... -
Decreased blood oxidative stress after repeated muscle-damaging exercise
(2007)Purpose: To examine the effect of repeated muscle-damaging exercise on the time-course changes in several indices of muscle damage, and to compare them with changes in blood oxidative stress indices. Methods: Twelve females ... -
Effect of exercise on oxidative stress in individuals with glucose-6-phosphate dehydrogenase deficiency
(2006)The effect of exercise on oxidative stress in glucosee-phosphate dehydrogenase (G6PD)-deficient individuals was investigated. Materials and Methods: Nine G6PD-deficient males and nine males with normal G6PD activity were ... -
Effects of xanthine oxidase inhibition on oxidative stress and swimming performance in rats
(2008)The aim of this study was to examine the effect of allopurinol, a xanthine oxidase inhibitor, on oxidative stress and physical performance after swimming until exhaustion in rats. Blood and gastrocnemius muscle samples ... -
Exercise-induced oxidative damage in a person with glucose-6-phosphate dehydrogenase deficiency
(2004)The purpose of this case study was to examine the effects of a single submaximal aerobic workout on the extent of oxidative stress biomarkers in blood in a patient with glucose-6-phosphate dehydrogenase deficiency (G6PD) ... -
Exercise-induced oxidative stress in G6PD-deficient individuals
(2006)Purpose: This study was designed to investigate whether individuals with glucose-6phosphate dehydrogenase (G6PD) deficiency can exercise without greater perturbations in their redox status compared with non-G6PD-deficient ... -
Favorable and prolonged changes in blood lipid profile after muscle-damaging exercise
(2008)Purpose: To examine the effect of repeated muscle-damaging exercise on the time-course changes in blood lipid and lipoprotein profile and compare them with changes in indices of muscle function and damage. Methods: Twelve ... -
Flavonoids induce HIF-1 alpha but impair its nuclear accumulation and activity
(2008)Hypoxia-inducible factor-1 alpha (HIF-1 alpha) is the regulatory subunit of the transcription factor HIF-1, which is highly involved in the pathology of diseases associated with tissue hypoxia. In this study we investigated ... -
Increased oxidative stress indices in the blood of child swimmers
(2007)The blood redox status of child athletes is compared with that of age-matched untrained individuals. In the present study, 17 swimmers (10.1 +/- 1.6 years) and 12 non-athletes (9.9 +/- 1.1 years) participated. Reduced ... -
Lipid peroxidation and tissue damage
(1999)In recent years it has become apparent that the oxidation of lipids, or lipid peroxidation, is a crucial step in the pathogenesis of several disease states in adult and infant patients. Lipid peroxidation is a process ... -
Sampling time is crucial for measurement of aerobic exercise-induced oxidative stress
(2007)Purpose: To thoroughly investigate the time-course changes of several commonly used markers of oxidative stress by performing serial measurements during a 24-h period after an acute bout of strenuous cardiovascular exercise. ... -
TIME-COURSE OF CHANGES IN OXIDATIVE STRESS AND ANTIOXIDANT STATUS RESPONSES FOLLOWING A SOCCER GAME
(2010)Fatouros, IG, Chatzinikolaou, A, Douroudos, II, Nikolaidis, MG, Kyparos, A, Margonis, A, Michailidis, Y, Vantarakis, A, Taxildaris, K, Katrabasas, I, Mandalidis, D, Kouretas, D, and Jamurtas, AZ. Time-course of changes in ... -
Uniform and prolonged changes in blood oxidative stress after muscle-damaging exercise
(2007)Background: The effect of eccentric exercise on the time-course changes in several indices of muscle damage and blood oxidative stress was examined. Materials and Methods: Isometric torque, delayed-onset muscle soreness, ...
