Abstract. Purpose: to determine peculiarities of formation of junior schoolchildren's motor skills. Material: 172 pupils participated in the research. In every parallel of forms there were 48 pupils. Factorial experiment of 2 3 type was conducted. Results: it was determined that effectiveness of schoolchildren's training (1 st -2 nd forms -to forward roll; 3 rd -4 th forms to vault) is influenced positively on be the following: increasing of attempts up to 12 times, quantity of repetitions in one attempt -up to 3 times, interval of rest shall be within 60-180 sec. In training process Attention is accentuated on quantity of attempts. For each form specific methodic peculiarities of exercise's fulfillment were formulated. Conclusions: factorial experiment of 2 3 type permitted to study multi-factorial structure of training process of 1 st -4 th forms' schoolchildren and specify optimal correlations of quantity of attempts, quantity of repetitions in one attempt and rest interval.

The study purpose was to substantiate theoretical and methodological grounds and the concept of a research program of the training process based on modeling of individual components of the young gymnasts’ training system.  Materials and methods. The study involved: 30 gymnasts – 3rd senior category, 30 gymnasts – 2nd senior category, 26 gymnasts – 1st senior category. Young gymnasts participating in the experiment received athletic titles from the 1st category to master of sports (1st c. – 18 persons, CMS – 15 persons, MS – 12), won competitions of different levels. To substantiate the research program, the study used the following methods: modeling, systems approach, methods of theoretical analysis and generalization to reveal the essence, leading development trends of the young gymnasts’ training system and to define theoretical prerequisites and methodological approaches to its further improvement; pedagogical testing, methods of recording sensorimotor reactions, methods of recording the cardiovascular system state, observation and pedagogical experiment to determine young gymnasts’ model characteristics, modes of training loads; methods of mathematical analysis (logistic and asymptotic functions) to determine the regularities of allocating the means of primary focus during motor abilities development, teaching gymnastic exercises and training for competitions; mathematical methods of planning multifactorial experiments to study the regularities of motor abilities development, teaching process and training for competitions. The obtained experimental material was processed using statistical analysis software (SPSS 20). Results. The developed conceptual approaches to determining the normative characteristics of training loads in the process of young gymnasts’ training include: analysis of the effects of different modes of training on a change in the functional state; determination of the optimal increase in the functional state indicators; calculation of a mode of training that can ensure the optimal increase in the indicators of young gymnasts’ functional state. Conclusions. The developed research program makes it possible to define the regularities of motor abilities development, teaching gymnastic exercises and training for competitions; to obtain the models of young gymnasts’ training process. As a result of implementing the research program, the study substantiated factorial designs for studying the influence of modes of alternation of exercises and rest on the effectiveness of motor abilities development, motor skills formation, and the effectiveness of training young gymnasts for competitions.

The purpose of the study was to determine the impact of knowledge considered as a methodological basis of motor learning on the effectiveness of motor skills development in children and adolescents. Materials and methods. Young gymnasts aged 7-13 participated in the experiment. At the first stage – young gymnasts aged 8 (16 groups of 6 people each). At the second stage – young gymnasts aged 8 (3 groups of 6 people each), young gymnasts aged 13 (2 groups of 6 people each). Both philosophical and general scientific research methods were used to solve the tasks set, among which were: dialectical method, systems approach, modeling, pedagogical experiment organized according to the scheme of a 2k factorial experiment. Results. A positive effect of learning depends on the consistent solution of learning tasks and rational application of methods. This is indicated by the following: firstly, the total impact of factors reduces the number of repetitions when teaching young gymnasts a side handspring (by 23 repetitions), secondly, the total interaction increases the duration of training by 9 repetitions. Obviously, studying the decomposition of learning tasks can improve the effectiveness of learning in general. Conclusions. The learning process structure is most influenced by the conclusions of the theory of functional systems (43%, p < 0.001), the theory of movement construction (41%, p < 0.001), and the theory of management of knowledge acquisition, formation of actions and concepts (2.6%, p < 0.05). A positive effect of learning depends on the consistent solution of learning tasks and rational application of methods.

The study objective is to substantiate the modes of alternation of physical exercises and rest intervals in the process of teaching series of tasks aimed at motor skills development in boys aged 14 years.  Materials and methods. The participants in the study were 40 boys aged 14. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To achieve the objective set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, methods of mathematical experiment planning. Results. The results of the analysis of variance and regression models show that the optimal mode of performing series of training tasks is within the range of 6-12 exercise repetitions with rest intervals of 60-120 seconds. In the proposed matrix of factorial design, the selected step of factor variation is sufficient to study the impact of different modes of physical exercises on the effectiveness of teaching children and adolescents.  Conclusions. A 22 type experiment made it possible to examine the multifactorial structure of the process of teaching boys aged 14, using the program of algorithmic instructions, to specify the optimal balance between factors for their use when teaching physical exercises during physical education classes. The best options for teaching series of tasks to boys aged 14 during physical education classes are: series 1 — 12 repetitions, rest interval of 120 s; series 2 — 12 repetitions, rest interval of 60 s; series 3 — 6 repetitions, rest interval of 60 s; series 4 — 12 repetitions, rest interval of 60 s; series 5 — 12 repetitions, rest interval of 120 s; series 6 — 6 repetitions, rest interval of 60 s.
