“…However, the activity of catalase significantly increased after control exercise. Postexercise increase of CAT activity was also observed by other authors [ 33 – 35 ]. The increase of antioxidant enzymes activity measured in cellular material is usually related to elevated enzyme synthesis.…”

The aim of the study was to determine the effect of single whole-body cryotherapy (WBC) session applied prior to submaximal exercise on the activity of antioxidant enzymes, the concentration of lipid peroxidation products, total oxidative status, and the level of cytokines in blood of volleyball players. The study group consisted of 18 male professional volleyball players, who were subjected to extremely cold air (−130°C) prior to exercise performed on cycloergometer. Blood samples were taken five times: before WBC, after WBC procedure, after exercise preceded by cryotherapy (WBC exercise), and before and after exercise without WBC (control exercise). The activity of catalase statistically significantly increased after control exercise. Moreover, the activity of catalase and superoxide dismutase was lower after WBC exercise than after control exercise (P < 0.001). After WBC exercise, the level of IL-6 and IL-1β was also lower (P < 0.001) than after control exercise. The obtained results may suggest that cryotherapy prior to exercise may have some antioxidant and anti-inflammatory properties. The relations between the level of studied oxidative stress and inflammatory markers may testify to the contribution of reactive oxygen species in cytokines release into the blood system in response to exercise and WBC.

“…This suggests that adaptations of antioxidant defence due to chronic exercise protect athletes from oxidative stress induced not only by an exercise stimulus but also most likely in a number of non-exercise conditions. The decrease in SOD due to exercise testing on an ergometer was also confirmed by Mrowicka et al [30], who reported that SOD activity was significantly more decreased in athletes compared to non-athletes after cycling ergometry. Another study showed that in non-athletes, SOD activity actually increased in response to any load of exercise on a cycling ergometer [41].…”
