Background. The objective of the study was to explore the dynamics of the functional state of the central nervous system (CNS) and neurophysiological processes of girls 16-18 years old in the context of their transition to a new level of social organization. Material and methods. The functional state of the CNS was studied in girls 16-18 years old in a state of relative muscular rest through observation of visible motive reactions, Loskutova’s method, and in the fifth minute of renewal after the physical loading with variable power. Results. We found that 17 year-old girls had the best functional CNS capabilities. The reduced adaptive capacity of the CNS in 16 year-old girls is due to their necessity for adaptive reorganization of regulatory mechanisms to new social conditions: examinations and university entry. After physical activity, 16 and 18 year-old girls registered stress reactions, indicating decreased CNS adaptation. Conclusions. 17 year-old girls were observed at rest to have better CNS functionality compared to the other age groups. Analysis of the dynamics of the functional CNS states of 16–18 year-old girls after exercise resulted in the identification of two main reaction types: 1) reduction of the basic criteria at high initial values; 2) increase of criteria of a general functional state of a brain at low raw data.
The article is devoted to the study of asymmetry in physical development of arm wrestling athletes at the stage of sports perfection. It presents the results of a pedagogical experiment with the use of static motor-cognitive tests and stabilometry in the detection of asymmetry and proves the effectiveness of the developed system of physical training, based on the achieved improvements of the indicators of equilibrium function of arm wrestlers compared to the standard training system.
Novelty of research is to structure classes for various areas of health aerobics and mental fitness that will be held according to separate and combined programs. Tasks of the paper: to reveal the content of health aerobics and mental fitness exercise package program; to present recommendations for combination of different types of exercises; to establish changes in functional status of women under the influence of exercise according to the proposed program. Research methods. Analysis and generalization of literature, assessment of the level of women’s functional status, methods of mathematical statistics. Results of the research. The article deals with the content of health aerobics and mental fitness comprehensive program. Experimental program classes were held during 11 months, three times a week and lasted for 60 minutes. Among a wide variety of programs, the following exercises were used: classical aerobics, dance, floor work, mental fitness, aerobics with elements of martial arts, aerobics in the water, using different equipment and cyclic aerobics types. Mental fitness was used as a separate class, and as part of combined classes. Recommendations concerning a combination of aerobic exercise types, mental fitness and floor work blocks were given. The effectiveness of classes according to the suggested program was proved by positive changes of women functional status standard indexes. Conclusions. 1. Experimental package program health aerobics and mental fitness class consists of two stages (autumn-winter and spring-summer) and includes 11 periods (months) of classes. 2. The effectiveness of experimental program is proved by positive changes in indicators for functional status of women’s cardiovascular and respiratory systems (р<0,05–0,001).
