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 CRH on NO bioavailability, ROS production and antioxidant defense systems in endothelial EAhy926 cells
(2010)Local or 'Immune' Corticotropin-Releasing Hormone (CRH) is secreted in peripheral tissues and plays a direct immunomodulatory role as an endocrine or paracrine mediator of inflammation. The present study was undertaken to ... -
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 as a model to study redox homeostasis in blood: the effect of protocol and sampling point
(2012)Twenty males ran either on a level treadmill (nonmuscle-damaging condition) or on a downhill treadmill (muscle-damaging condition). Blood and urine samples were collected before and after exercise (immediately after, 1h, ... -
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 ... -
The impact of sodium nitroprusside and ozone in kiwifruit ripening physiology: A combined gene and protein expression profiling approach
(2015)Background and Aims Despite their importance in many aspects of plant physiology, information about the function of oxidative and, particularly, of nitrosative signalling in fruit biology is limited. This study examined ... -
INCREASED OXIDATIVE STRESS BLOOD MARKERS IN WELL-TRAINED ROWERS FOLLOWING TWO THOUSAND-METER ROWING ERGOMETER RACE
(2009)Kyparos, A, Vrabas, IS, Nikolaidis, MG, Riganas, CS, and Kouretas, D. Increased oxidative stress blood markers in well-trained rowers following two thousand-meter rowing ergometer race. J Strength Cond Res 23(5): 1418-1426, ... -
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 ... -
Oxidative stress due to radiation in CD34(+) Hematopoietic progenitor cells: protection by IGF-1
(2012)Radiation exerts direct as well as indirect effects on DNA through the generation of reactive oxygen species (ROS). Irradiated hematopoietic progenitor cells (HPCs) experience DNA strand breaks, favoring genetic instability, ... -
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. ... -
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, ...
