The purpose of this study was to investigate the individual and combined antioxidant effects of menstrual cycle phase-related alterations in blood serum oestradiol concentrations and of dietary vitamin E supplementation on exercise-induced oxidative stress and muscle performance. A group of 18 sedentary women, aged 19–35 years, were given supplements of 300(More)
The oxidative effects were investigated of exhausting exercise in smokers, and the possible protective role of 400 mg · day−1 vitamin E (Vit E) supplementation over a period of 28 days. The subjects exercised to exhaustion including concentric-eccentric contractions following maximal cycling. The haematocrit and haemoglobin, leucocyte (WBC), plasma lactic(More)
BACKGROUND Black tea is known to have protective effects against plasma lipid and lipoprotein oxidation, but its influence on lipid peroxidation in tissue has been less studied. The effect of oral black tea consumption on protein oxidation has also not been demonstrated. The present study investigated the antioxidant effects of oral black tea consumption.(More)
The relative oxidative insult caused by exercise and smoking on biological systems are well documented, however, their cumulative influence needs to be clarified. In order to examine the collective effects of exercise and smoking on oxidant and antioxidant parameters, young male smokers (n=10) and non-smokers (n=10) made to perform a negative slope (10%)(More)
Autoxidation of globin chains and iron overload are the suggested mechanisms for the increased oxidative stress in beta-thalassemia. The aim of this study was to evaluate the extend of lipid peroxidation and antioxidant status of patients with beta-thalassemia and iron deficiency anemia (IDA) and compare the results with healthy subjects. Oxidant and(More)
