ОСОБЕННОСТИ АДАПТАЦИИ ЛЕГКОАТЛЕТОВ К УСЛОВИЯМ СРЕДНЕГОРЬЯ

Athletics is one of the most popular and accessible sports. However, qualitatively organized training sessions using new approaches and methods are required for effective training of elite athletes. Among such approaches is conducting training sessions in these conditions. The positive effect of training sessions in the midland conditions generally is not in question for experts. But the specific features of adaptation of athletes to midland conditions have not been fully clarified. The purpose of the research was to study the specificity of adaptation of the indicators of cardiac pump function of athletes specializing in different areas to midland conditions. Summing the above, it can be stated that systematic muscle training in the midland have a different effect on the changes in the stroke volume indicators of athletes of different specializations. The common to all athletes is that a steady downward trend is observed in stroke volume in the first four weeks of muscle training, the only exception is a group of middle distance runners, whose stroke volume, on the contrary, increased in the first week. A kind of acclimatization and adaptation to midland conditions is marked in most of the groups of athletes by the end of training camps, which is shown in higher rates of stroke volume to the level of original values. It should be noted that stroke volume of sprinters has not increased to the level of initial values by the end of the training sessions. Summarizing the above, it can be stated that a significant increase in heart rate performance is marked in all examined groups of athletes during six weeks of training in the midland comes compared with the original data. The stroke volume indices, on the contrary, are reduced. The researchers have found that long and ultra-long distance runners adapt to the midland conditions much faster than sprinters and middle distance runners.
