Abstract
To study the dynamics of cardiorespiratory parameters in the anaerobic threshold zone of ski racers throughout the annual training cycle. Materials and methods: 300 examinations of 49 professional ski racers of I category and candidate masters of sports (aged from 15 to 32 years, mean age - 19,7±1,3 (M±m)) were carried out in the breath-by-breath mode on an Oxycon Pro ergospirometric system (Erich Jaeger). Maximal oxygen consumption (MOC: absolute and per kilogram of body weight) was detected during pass-fail test. Heart rate (HR), oxygen consumption (VO 2 ), oxygen pulse and maximal load were registered in the anaerobic threshold zone. Difference between the actual and theoretically calculated HR, VO 2 percentage (relate to maximal oxygen consumption) was calculated. Results: pulse increase in the anaerobic threshold zone by 20% prolonged aerobic activity of ski racers and increased maximal aerobic load by 20%. Conclusions: the most favorable values of cardiorespiratory parameters were registered during the preparation period, and the least - during the competition period. This fact requires correction of the training process and rehabilitation.
