Special age and skills-related features of effective adaptation and selection in sports reserve training

Aim. The study aims to substantiate health monitoring, implement the effects of stress and adaptation, identify selection criteria and establish an integral rating indicator (IRI) in sports reserve training. Materials and methods. Representatives of cross-country skiing, swimming, middle-distance running, steeplechase, speed skating, wrestling, kickboxing, diving, orienteering, ice hockey were examined. The age of athletes varied from 18 to 22 years, their sports experience was 6-8 years. Sports skills level included the first adult category, Candidate for Master of Sport, Master of Sport, International Class Master of Sport. The following equipment was used in the study: Oxycon Pro Mobile, Schiller, Digi-Lite (Rimed), non-invasive AMP analyzer, MBN force platform, 3D scanner, polydynamometer, MARG 10-01 (Mikrolux). Data processing was performed with the methods of mathematical statistics. Results. Polyfunctional, metabolic, immunological features of resistance and special endurance were established. The criteria indicating successful sports performance, evaluative activity, connective tissue stability, neuroplasticity and adaptation were developed. Conclusion. The informative coefficients of statokinetic stability and resistance to hypoxia was obtained, as well as the integral rating indicator of successful competitive performance. An analysis of effective adaptation, fitness variability, normal limits, stable and premorbid health states, overtraining and overwork is proposed.
