Non-invasive approach for the assessment of oxidative stress after intense judo activities

Oxidative stress induced by physical activity has received much attention in recent years due to numerous research papers. Physical activities (aerobic, anaerobic and resistance training) lead to an increased production of highly oxidative substances (RONS, both oxygen and nitrogen containing radicals) and this effect depends mainly on the intensity of muscular work. The combination of anaerobic and aerobic energy systems, as seen in judoka, provides more pathways for free radical production than single exercise training. The purpose of this study was to investigate the use of a non-invasive, simple battery to assess and monitor oxidative stress in judo athletes to better characterize the oxidative stress response to anaerobic and aerobic incremental exercise typical of the judo discipline.
