3.4. Oxidative Stress and Nordic Walking
Changes in 3-NT and 4-HNE concentrations showed that Nordic walking training induced a decrease in the concentration of these indicators (for 3-NT after 3 weeks of training, for 4-HNE after 3 and 6 weeks). Moreover, these changes were observed also 3 weeks after the training period (follow up). Changes in 8-OHdG and 8-isoPGFa2 were ambiguous, and no effect of exercise was observed for 8-OHdG, but there was a tendency to increase in 8-isoPGFa2. Similar results were obtained by Kortas et al. [
