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.
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.
