Adaptation of junior orienteers to loads, developing local-regional and special muscular endurance

Purpose: complex assessment of junior sport orientation athletes in conditions of concentrated training of local-regional muscular endurance and stroke loads (final part of preparation for competitions). Materials: in the research sport orientation athletes (n=34, age 13-16 years) participated. The athletes were divided into tested group (n=17) and group of comparison (n=17). In every group there were 17 boys and girls. The tested group consisted of volunteers, who practiced sport orientation. Comparison group included average distance and steeplechase runners. Results: In system of junior orienteers’ training we found: gender distinctions in carbohydrates and fats consumption (in the ranges of aerobic and anaerobic thresholds; substantial physiological changes in static-kinetic balance (tests with open and closed eyes. Dynamic coefficient of balance in main stance was better in sport orienteers, comparing with runners. Conclusions: it is recommended to fulfill exercises in conditions of stretching, combined with motor actions of speed-power orientation and relaxation
