ABSTRACT
Introduction: The effect of whole-body cryostimulation (WBC) on the biomarkers of oxidative stress, lysosomal enzymes, creatine kinase and cortisol was studied.
Material and methods: The rowers underwent two 6-day training cycles: with pre-training daily WBC (temperature: from –125°C to –150°C) and without cryostimulation (control). Blood samples were taken before and after the third and sixth day of training.
Results: The activity of superoxide dismutase and glutathione peroxidase was lower (by 44% and 42%, respectively) after the third day of training with WBC than without WBC. The concentration of lipid peroxidation products was also lower after the training preceded by WBC. Moreover, the acid phosphatase activity was 50% lower after the third day of training with WBC than training without WBC. Considering the antioxidant enzymes activity during training without WBC, the increase of superoxide dismutase and glutathione peroxidase activity was observed after the third day of training (by about 74% and 100%, respectively). The level of lipid peroxidation products also increased after the training without WBC. No statistically significant changes were observed in creatine kinase activity after the training preceded with WBC, while after the training without WBC activity of this enzyme was two-fold higher than before the training.
Conclusions: The use of WBC prior to training may reduce the risk of oxidative stress and the extent of muscle fibre injuries provoked by intense exercise. The WBC seems to be an effective and safe method for limiting exercise-induced damage; thus it may be used in biological regeneration of sportsmen.
