Abstract

The research touches on an interesting and important scientific problem that lies in the contradiction between two circumstances. The first circumstance is the lowering of the age limit for doing judo. And the second circumstance is the necessity to carefully dosing the load, training young judokas, taking into account their active growth and development. Thus, the analysis of the cardiovascular system’s reactions to the applied load among judokas of preschool and primary school age is relevant and new for experimental research. The purpose of this research is to determine the cardiovascular responses (“costs” / “physiological price”) among judokas of preschool and primary school age to mental and physical stress (using the example of the general preparatory stage in the yearlong macrocycle, in particularly, on the example of the first retracting and the first basic mesocycles). The methods of this research: comparative method, longitudinal method, a method of included pedagogical observation, a method of recording, a method of control tests, a forming natural closed sequential pedagogical experiment (according to the scheme of a single difference), case studies, frequence’s analysis, correlation’s analysis, regression’s analysis, genetic method, theoretical modeling. As a result of the study, a beneficial effect of the pedagogical technology “Safe Judo” on the trainness’s increasing of the cardiovascular system’s functions among judokas of preschool and primary school age was revealed (in particularly, an increasing in systolic blood volume, an increasing in minute blood volume, as well as a decreasing in the number of arrhythmias).
