Abstract
Aim. The paper focuses on adaptation that leads to high sports performance and results from huge training loads (HTL) for each athlete by means of variable application of ski training combinations. Research organization and methods. The subjects under observation were two ski racers (Master and Candidate Master of Sports), 20–21-year old, with 10–12 years of sports experience. Results. It was revealed that skeletal muscle blood flow was over the reference values (14.56–16.93 %, p < 0.05), and cerebral blood flow per 100 g of tissue and cerebrospinal fluid pressure were within control limits. We analyzed the parameters of pulmonary circuit resistance and the systemic circulation time. The consumed power of life support in Master of Sports was over the reference values (p < 0.05). Both skiers had low resting oxygenation rate in (in Master of Sports it was 262.09 ml/min, in Candidate Master – 244 ml/min). Conclusion. Thus, ski racers’ sport performance is associated with specific adaptive alteration of the respiratory and cardiovascular systems; the indices obtained from the results of the research may be applied as model characteristics in evaluation of ski racers’ preparedness for competition, in correction of educational and training process and in organization of rehabilitation measures.
