BACKGROUND: Training process under the conditions of middle-altitude hypoxia is an effective way to increase special physical fitness of ski racers. However, there is still no appropriate physiological justification of the altitude above sea level that would provide the maximum progress of functional capacity and abilities of leading systems of the body in ski racers without health risks.
METHODS: The aim of our research was to establish the integral indicator that would make it possible to calculate the required altitude above sea level optimal for the training process and to regulate the impact of hydrostatic pressure on the effectiveness of adaptation of the cardiorespiratory system.
RESULTS: It was found that the alternate introduction of four 21-25-day mesocycles into the training macrocycle of ski racers increased their sports performance. The finishing time for 15 km CL race in the experimental group was 00:39:37.04±0.36 h in contrast to 00:42:14.08±0.42 h in the control group (p <0.05); for 15 km SK race the results were 00:37:00.26±0.32 h and 00:39:24.23±0.36, respectively (p <0.05).
CONCLUSIONS: Maintaining the central venous pressure at a level of 63 mm H2O or lower considerably contributes to ski racers’ sports performance.
