The systemic effect of low temperature suggests that sessions in a cryogenic chamber might improve

athletes’ capacity as a standard element of training. Therefore the authors decided to evaluate the impact of

10 sessions of whole body cryostimulation (WBCT) on aerobic and anaerobic efficiency as well as on selected

blood count parameters. The study group included 32 volunteers – 16 women and 16 men. The volunteers

underwent 10 sessions of WBCT in a cryogenic chamber. Blood samples (RBC, WBC, PLT, HGB, HCT) were taken,

and aerobic and anaerobic efficiency and lactate concentration in capillary blood were measured before the first

session and one day after the last one. No significant differences were observed in values of aerobic capacity

after 10 sessions of WBCT. There was a rising trend in men and a declining trend in women. The lactate

concentration did not differ significantly before and after WBCT. A slight rise in aerobic and anaerobic threshold

was observed in men, while in women the values slightly fell. The Wingate test showed no significant differences

in results before and after cryostimulation. Only the TOBT was significantly shorter in men (6.12±1.49 vs

3.79±1.14 s). The WBCT sessions resulted in a significant rise of the haematological parameters both in women

and men, excluding HCT, which showed a statistically insignificant rise. Ten sessions of whole body cryostimulation

did not affect aerobic or anaerobic capacity in the tested group, although it improved the blood count parameters.
