Influence of the ten sessionsof the whole body cryostimulationon aerobic and anaerobic capacity

Objectives: The aim of this study was to determine the influence of whole body cryostimulation on aerobic and anaerobic capacities. Materials and Methods: To test the hypothesis that whole body cryostimulation improves physical capacity, thirty subjects (fifteen males and fifteen females) undertook two ergocycle trials before and after the ten sessions of cryogenic chamber treatment. To assess baseline aerobic capacity, the progressive cycle ergometer test was applied. This allowed determination of maximal oxygen uptake and ventilatory thresholds. Twenty-second Wingate test was performed to assess baseline levels of anaerobic power. After finishing the treatments in the cryogenic chamber, the exercise protocol was repeated. Before the first, and after the last whole body cryostimulation, venous blood samples were drawn to determine basic blood values, including levels of erythrocytes, leukocytes and thrombocytes, hemoglobin concentration, and hematocrit. Results: There were no changes in aerobic capacity, in both females and males, after ten sessions of 3-minute-long exposures to cryogenic temperature (-130°C). Participation in the whole body cryostimulation caused an increase in maximal anaerobic power in males (from 11.1 to 11.9 Wxkg-1; P < 0.05), but not in females. Conclusions: It can be concluded that whole body cryostimulation can be beneficial, at least in males, for increasing anaerobic capacity in sport disciplines involving speed and strength.
