Functional state of adolescents during cognitive activity depending on aerobic power

Aim. The aim of this article is to reveal the features of functional state in adolescent school students characterized by the high and low level of aerobic power development. Materials and methods. We examined 162 male pupils aged 13-14 belonging to the main medical group. We used a variety of indicators characterizing physiological, psychological and behavioral aspects of the functional state of the body. As informative integral indicators of the maximum power of aerobic process we used maximum oxygen consumption, PWC170 test and load power with a maximum time for the load performed of 900 sec (W900). As a result of statistical processing we divided all participants from the sample studied into 3 groups depending on the level of aerobic capacities of the body. Results. The results obtained demonstrate that the functional state of adolescents aged 13-14 significantly depend on the development of aerobic capacities of the body. We established that boys with a powerful aerobic system of energy supply differ from untrained peers by the decreased activity at quiet wakefulness and less pronounced changes in vegetative indicators of functional state under intense cognitive load against a high adaptation potential of the body. They are characterized by the increased effectiveness of the activity combined with the high scores of well-being, activity and mood assessment. Conclusion. The level of aerobic power can be considered as a factor determining the changes in adolescents’ functional state under intense cognitive load.
