title: [The age dynamics of the factors of the CRS functioning training of teenagers' organisms under identical physical load].
abstract: The age dynamics of the factors of the Cardio-Respiratory System (CRS) functioning training and its influence on the identical direction as well was carried out on 33 sportsmen of different specializations. The testing sportsmen were divided into two groups: Group I--conditionally--stayers with higher indices of the maximum oxygen consumption (VO(2max)) from the beginning; Group II--conditionally--sprinters with relatively low initial indices of VO(2max). It is concluded that the development of the factors of the CRS functioning training has a heterochronic character. The factor increase of the aerobic power, economicity and stability is mostly revealed in teen-agers, with higher primary values of VO(2max). before the training beginning. The negative correlation in dynamics of aerobic and anaerobic productivity power has not been revealed. It is shown, that the aerobic power of CRS reaches the limits of the reaction norm on the early stages of the age development as compared to the anaerobic power.
