In this study higher activity of certain lysosomal enzymes with concomitant lower a1-antitryspin activity was revealed in serum of kayaker women after intense exercise without any external stimuli as compared with the exercise preceded by extreme cold application. Whole-body cryostimulation may have hormetic, beneficial impact on reduction of muscle damage.
Conclusion:
In studied group of kayaker women the common marker of muscle damage like creatine kinase remains unchanged and the stress hormone—cortisol shows only a decreasing tendency after the WBC. Nevertheless, we found significant changes in activity of lysosomal enzymes and activity of protease inhibitor, which are also accredited parameters of post-exercise changes in organism.
Thus we propose that those proteins may be novel indicators of the effects of application of whole-body cryostimulation in sportsmen.
