Розглянуто особливості специфічного впливу тренувальних навантажень різної спрямованості на організм юних спортсменів. В експерименті брали участь 75 дівчат підліткового віку, які займалися різними видами спорту (група А – швидкісно-силові види спорту, група Б – види спорту на витривалість) та 30 учениць загальноосвітніх навчальних закладів, які не займалися спортом у віці 12–15 років. Описана методика проведення психофізіологічних досліджень у вивченні психічної функції мислення. Дається порівняльний аналіз змін показників зазначеної функції обстежуваних. Виявлено, що специфіка тренувального процесу накладає відбиток на характер змін функції мислення у юних спортсменок 12–15 років.
The peculiarities of the specific influence of training loads of different directionality on the body of young athletes have been considered. The research was conducted on the basis of Brovary Higher School of Physical Education. The experiment involved 75 teenage girls who took sports (group A-speed and power sports; track and field (100 and 200m running, jumping, shot put and discus throwing), freestyle wrestling; group B-endurance sports; skiing, track and field (800m, 1500m and 3000m), swimming (200, 400, 800m), and 30 students of the general educational institution № 3 in Brovary, who did not go for sports at the age of 12-15 years. The methodology of performing psychophysiological research in the study of a memory mental function was described. A comparative analysis of changes in indicators of the specified function in examinees is given. The results of research the study indicate that the training process directionality has a specific impact on the development of logical thinking function in athletes. Thus, the indicators of the specified mental function are significantly higher in the representatives of sports, which mainly develop the quality of endurance, compared to speed and power sports. It was also established that the factor of sexual dimorphism does not make significant adjustments in the specifics of changes in the indicators of logical thinking function. Although there were differences between teenage athletes of different genders according to the analysis of psychophysiological indicators, they had only quantitative character. Adolescents of different sexes who are engaged in swimming have the highest level of development of mental thinking function. There fore the foregoing gives reasonable grounds to believe that the specifics of the training process, its directionality equally influence the nature of changes in the mentioned mental function of adolescents, regardless of their sexual identity.
