Adaptation to endurance load in youths

Abstract

Purpose: the study of peculiarities of adaptation to endurance load in youths 15-17. Material: Material: 90 youths age 15-17 were examined. All of persons divided into three age groups: 15 age (30 youths), 16 age (30 youths), 17 age (30 youths). All of youths were separated on three groups by morphological development. The first group related with Accelerated of Physical Development (APD). The second group associated with Moderate Physical Development (MPD). The third group corresponded with Retarded Physical Development (RPD). The Cooper’s 12-minute test, used a 15-minute run of fixed distance covered during this interval of time were used. Results: The complex evaluation of tempos of morpho-functional adaptation of organism in youths was studied. In results of this data the programs of the training of the main physical abilities were elaborated. As a result of this work were differentiated the separated the groups of youth on different types. Individual typological peculiarities of the physical development, puberty, the type of physique, the activity of the respiratory and cardiovascular systems of youths were studied. The individual indicants of the body exertions were identified; the ways of training of main motional abilities by the successions of exercise and their relation to the endurance development were clarified. Conclusions: The streaming of the15-17 youths into several groups according to the rate of development shows the differences not only in the morphofunctional indicants, but also in the reaction of the organism to the single-action exertions and adaptation for them in the exercise system. As a result, it increases the effectiveness of the process of the physical preparedness. The selection of the physical exertions, that are relevant to according the peculiarities of age groups leads to improve of adaptation process to physical load. It result in growth of the efficiency and specified the sensitive periods of the development of endurance in youths.
