The investigation of oxidative metabolism and the potential adaptation of students bodies to physical activity remains a pressing issue. Objective: This study aims to examine the characteristics of free radical processes and the activity of the antioxidant system in students at different academic levels, both at rest and during maximal physical activity. Materials and methods: The oxidative metabolism at rest was analyzed in 286 male students from the 1st to 3rd years. From this group, 75 students were chosen to evaluate the response of oxidative metabolism during maximum physical activity. We evaluated the maximum intensity of luminescence and the inverse index related to the total light sum of biochemiluminescence, as well as the concentration of malonic dialdehyde and the activity of superoxide dismutase and catalase, enzymes that inhibit lipid peroxidation reactions. Results: The results indicate that, in a resting state, third-year students exhibited signs of relative maladaptation when compared to first-year males, as demonstrated by an increased rate of free radical production measured by the biochemiluminescence method. This is reflected in elevated levels of maximum luminescence intensity (Imax), the reciprocal of the total light sum, and malonic dialdehyde concentration. Additionally, there is a moderate decrease in the activity of antioxidant enzymes, such as superoxide dismutase and catalase. During physical activity, there is a considerable increase in lipid peroxidation and the levels of reactive oxygen species (ROS) observed during 100 m sprints and pull-ups. The Imax values increased by 37.1% and 45.5%, respectively, while the inverse index of the total light sum of chemiluminescence (1/S) values decreased by 49.2% and 45.9%. The dynamics of the secondary product of lipid peroxidation, malondialdehyde (MDA), revealed an increase in its concentration of 17.0% and 19.4%, respectively. Additionally, maximum physical work capacity contributed to a reduction in the activity of superoxide dismutase and catalase, which decreased by 10.8% and 15.0%, and by 11.7% and 13.1%, respectively. Conclusions: The results of this study can be used to inform recommendations for enhancing the physical education and sports training programs for university students. They may also serve as a foundation for evaluating the effectiveness of proposed strategies and programs aimed at improving the physical and somatic health of future professionals.
