The peculiarities of organism’s regulatory system in 12
track-and-field athletes, who specialized in middle-distance
running (qualification MC and MCMK mid-age 24,5±3,06
years of age) were searched during their training in midrange
altitude at 2100 m height. We studied statistic, variation
and spectral characteristics of heart rhythm variability
at 2-3 and 11-12 days of staying in mountains. On the base
of heart rhythm variability, peculiarities analysis all the
examined athletes at preliminary adaptation period to midrange
altitude are divided into two groups. The increased
tensity of the athletes regulatory processes and prevalence
of sympathic influence was marked in athletes of the first
group (41,7 %). The second group of athletes (58,3 %)
demonstrated the balance of sympathic and parasympathic
influence and moderate tensity of regulatory systems of the
organism. The relationship between individual characteristics
of heart rate variability and the nature of adaptation
to the conditions of middle mountains was revealed, and
factors determining the functional state of the body’s regulatory
systems were identified. It was demonstrated that the
effectiveness of mountain training was higher in the second
group of athletes. At the same time the 12 day staying in
mid-range altitude conditions was not sufficient for the full
adaptation to chronic hypoxia.
