ИНТЕГРАТИВНАЯ РЕАКТИВНОСТЬ И РЕЗИСТЕНТНОСТЬ ОРГАНИЗМА ДЕВУШЕК ПОДРОСТКОВ 13–14 ЛЕТ, ЗАНИМАЮЩИХСЯ СПОРТИВНЫМ ОРИЕНТИРОВАНИЕМ, В УСЛОВИЯХ ПРИМЕНЕНИЯ НОВЫХ ТЕХНОЛОГИЙ В СИСТЕМЕ СПОРТИВНОЙ ПОДГОТОВКИ

Abstract

Aim. The aim of this study is to provide scientific and methodological support for sports training on the condition of comprehensive control. Materials and methods. We performed a systematic assessment of girls involved in sports for 3–4 years and having ranks of 3rd or 2nd class athletes in a senior group for orienteering (winter and summer) specialized in sprint and middle distances. We examined 17 girls aged 13–14. We used the following methods in our study: B.Kh. Landa’s approach to the assessment of physical fitness, the Bourdon-Anfimov test, ergospirometry on the Sсhiller’s diagnostic setup (Suisse) with data interpretation according to K. Wasserman, A.L. Syrkin and colleagues, urine tests on the express analyzer (FRG), and the AMP system analyzer (Ukraine). Results. Depending on age and qualification characteristics of athletes, we noticed improvement of quickness indices, speed-strength qualities and endurance. Under specialized basic and interval loads in the final stage of preparation to competitions, we noticed differently directed changes of the combined indices of functional systems, showing peculiarities of the auxological period, resulting in systematical tension and the presence of athletes in a forming phase of adaptation. Conclusions. Aerobic training conditions and the using of the glycogen – lactic acid system during physical actions episodes lead to body tension. However, body development (increased glycogen) results in adaptive and compensative changes in body integrative reactivity of young orienteers. Changes in the system of oxygen provision were compensated by the system of blood circulation. There is an increase in diffusive capacity due to trainings developing endurance.
