Adaptation of athletes to middle-altitude conditions via the intensive development of local-regional muscular endurance and strength motor capability, stretching, and relaxation

The purpose of our research is to justify the impact of progressive technologies influencing the processes of short-term reactions and effective long-term adaptation during the basic and contest periods of training. Approach. The research involved 30 volunteers who had agreed to submit to a fasting blood test (cubital vein). 15 of the volunteers were highly-skilled skiers, and 15 were highly-skilled medium-distance runners. Performed laboratory testing included the examination of processes of free-radical oxidation and of antioxidant protection system, cortisol level assessment, protein synthesis evaluation, system analysis of multifunctional state of the body and of postural indicators. Results. The mechanisms of warming-up, stable state, transient processes, fatigue and recovery of different athletes at the plane and in the middle-altitude are revealed. Multifunctional data of short-term reactions and long-term adaptation with phase state analysis. Conclusions. The obtained data reflect integrative activity of athletes' body under extreme conditions (loads, hypoxia, temperature, and competition-related stress). The revealed indicators of state determine effective adaptation and sport performance.
