Celem pracy była ocena różnic w poziomie stresu oksydacyjnego w trakcie wysiłku tlenowego i beztlenowego. Przeprowadzono badania na grupach chłopców trenujących dyscypliny o różnym charakterze pracy. Do oceny poziomu stresu oksydacyjnego posłużono się markerem stresu, jakim jest kwas moczowy. Oceniono również wielkość spożycia białka.

The aim of this study has been to investigate the influence of aerobic and anaerobic exercise on oxidative stress. The research was undertaken over a group of 61 young people of different physical activity (age group 15-18 years). The control group included sedentary persons. In the sportsmen group the amounts of uric acid (UA) and urea excreted in urine and body weight were measured in two series before and after training camp. In sedentary group there was only one series. Protein intake was assesed using urea excrection. In the control group the amounts of uric acid reached 60 µmol/kg m.c; in the aerobic exercise group 45.46 µmol/kg before the camp and 55.29 µmol/kg after; adequately 70.2 µmol/kg and 62.51 µmol/kg in the anaerobic exercise group. Protein intake frequently was different in comparison to required. The study shows high correlation between protein intake and uric acid excretion in all groups. The high protein intake seems to decrease participation of uric acid in anyoxidative deffence.
