Abstract
The aim of this study was to investigate the effect of cold-water immersion (CWI) on lipid peroxides and antioxidant enzymes in adult Taekwondo athletes after a match. A cross-sectional study was performed. After a Taekwondo match, the control group remained seated passively, while the treatment group immersed their legs below the knee joint in cold water at 10 °C. Blood samples were taken at pre-match, post-match, post-treatment, and post-rest, and changes in malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx) concentrations were analyzed. The results showed that there was a significant difference in MDA between the two groups, and while the CWI group had 19% lower SOD concentration compared to the control group, and the difference was not significant. However, in case of interaction for GPx concentration (p < 0.001), a statistically significant difference was found between the two groups (p < 0.05). In conclusion, CWI after a Taekwondo match elevates the concentration of antioxidant enzymes.

Summary
It is well known that free radicals and reactive oxygen species (ROS) produced in the human body cause cellular damage as well as aging and various chronic disease [1]. ROS are free radicals containing oxygen that are highly reactive. They contain an unpaired electron and have a strong tendency to achieve a stable state, by either taking or giving up an electron. When ROS is produced in the body, they react with lipids, proteins and DNA, and can cause functional impairments. When ROS attacks cellular membranes, they oxidize unsaturated fatty acids and form lipid peroxides; malondialdehyde (MDA) is used as a marker of lipid peroxide [3]
