Abstract. The program regulating the content of physical education lessons, aimed primarily at the formation of motor skills, is not able to have a significant impact on improving the motor conditions of elementary school pupils. The content of the lessons has a minimal impact on the development of endurance. The purpose of the study: optimization of physical education methods of primary school. Material and methods The study was conducted on the basis of GUO Secondary School No. 31 named after V. Khoruzhey, Vitebsk, for 12 weeks. The experiment involved schoolchildren 7-9 years old (n = 48). Experimental factor - motor tasks of cyclic and complex coordination nature, heart rate 50 - 70% of the maximum, 8-10 min. Methods: generalization and analysis of literary data; control tests; pedagogical experiment; anthropometry; methods of mathematical statistics. The results of the study and their discussion. The expected, statistically reliable, training effect from the implementation of the development was not achieved. With such a value of V with 17-93% in the indicators of half of the tests, it is impossible to achieve the required reliability of differences. Therefore, it is more legitimate to evaluate the quality of the program by the growth rate of X test indicators. 700 min. for 12 weeks is not enough for changes in motor conditions to be statistically confirmed. Due to the fact that the curriculum is aimed at the formation of motor skills, there is no reason to evaluate its quality by tests reflecting the measure of the development of motor qualities. The development of motor conditions without the use of influences in the developmental mode is very difficult in the conditions of a school lesson. Conclusion. The motor tasks installed in the program allowed the subjects of the experimental group to increase their motor conditions to the level of the requirements of the age norm. The fragmentary use of influences stimulating the development of various forms of motor manifestations of endurance not only significantly improved the functionality of the cardiovascular system (P 0.02), but also contributed to their effective implementation with power and aerobic modes of motor manifestation. It should be noted that the made changes contributed to the harmonious development of all motor abilities without exception.

The results of a study of the autonomous regulation of the heart rate in elite wrestlers with different dominance of the cerebral hemispheres were present in the manuscript 23 elite wrestlers. Were examined members of the National Team of Ukraine in Greco-Roman wrestling, aged 22-34 years-old. A body composition monitor "Omron BF511" and a computer electrocardiograph "Fazagraf" were used. It was revealed that elite wrestlers with a dominance of the right hemisphere have more intense regulation of the heart rhythm compared to wrestlers with a dominance of the left hemisphere of the brain. With an increase in the tension of the system of autonomous regulation of the heart rhythm in wrestlers with the dominance of the right hemisphere of the brain, the activation of the central and sympathetic division of regulation occurs. For the purpose of a more effective preparation process and in the development of individual training programs for elite wrestlers, it is necessary to determine the dominance of the cerebral hemispheres.

The article presents data on the effective building of strength training for middle distance runners in the autumn - winter macrocycle. It was revealed that the conjugated-sequential form of organizing loads of various predominant directions provides for a strict procedure for introducing loads into the process of training athletes with a gradually increasing degree of specificity and strength of the training influence. It was determined that in the six-month training cycle for middle-distance runners aged 13-14 years-old, the conjugated-sequential form of organizing loads with the element of concentration of strength loads has a more beneficial effect on the dynamics of the level of motor training than the complex-parallel one.
