Evaluation of efficiency of repulsion in speed-and-strength types of athletics

Efficiency of repulsion in speed-and-strength types of athletics is an integral measure of skill, since the performance of repulsive movements involves interaction of almost all organs and body systems. Dynamic repulsion lays the foundation for high sports results and the conditions of effective interaction of internal and external forces. With the special test exercises, one can determine the level of functioning of individual systems, on which the result of an exercise depends, which during training sessions provides focused opportunity to influence the stimulation of individual systems, increasing their level of activity. The article presents an electromyographic evaluation of the effectiveness of repulsion during the high jump at a run. The implementation of this method will make it possible to objectively evaluate the level of technical skills of athletes and purposefully influence the improvement of basic biomechanical characteristics of sports exercises

Краткая история графического изобразительного искусства в технике офорта

Стаття присвячена офорту – особливому виду друкарської графіки, що має свою власну естетику. У ній відображено короткі відомості про зародження і розвиток техніки офорту, як образотворчого мистецтва, що сьогодні актуально для розвитку сучасної авторської графіки, яка витісняється комп’ютерним дизайном.This article is devoted to etching – a special kind of printed graphics, which has its own aesthetics. It reflects a summary of the origins and development of etchings, as fine art, which is important nowadays for the development of modern authoring graphics, being displaced by computer design.Статья посвящена офорту – особому виду печатной графики, обладающей своей собственной эстетикой.

Ethno-cultural tourism as a promising area for inter-municipal and inter-regional cooperation in the development of rural areas in the Republic of Bashkortostan and the Chelyabinsk region

In the context of the coronavirus pandemic and the introduction of certain restrictions on movement between some countries, there is an increase in demand for domestic tourism in the constituent entities of the Russian Federation, including in the Republic of Bashkortostan. One of the promising, but still underdeveloped types of domestic tourism in Bashkortostan and the neighboring Chelyabinsk region is ethnocultural tourism, the potential of which is huge in terms of opening new jobs, organising new small and medium-sized enterprises. It can be considered as a promising direction for the diversification of the rural economy and tourism business, which can dramatically increase the income of the villagers and, in general, the quality of life in rural areas. In addition, it contributes to the preservation of tangible and intangible objects of historical memory, in particular, folk crafts and crafts, customs and traditions, and skills in the production of unique national cuisine products. On the example of depressed rural areas of the Republic of Bashkortostan and the Chelyabinsk region, the author updates the feasibility of enhancing the areas of intermunicipal and interregional cooperation in the field of rural ethnocultural tourism, including through the introduction of additions and changes to federal, regional and municipal programmes for the socio-economic development of the village, small and medium-sized businesses, agricultural cooperation, tourism and the inclusion in them of proposals to support ethnic entrepreneurship and the formation of ethnotourist clusters. The organisation of national (ethno) villages in the Argayashskiy, Kunashakskiy districts of the Chelyabinsk region and in the south-north-eastern regions of Bashkortostan, inter-municipal and inter-regional ethno-tourist clusters can contribute to a more efficient use of the ethno-cultural potential of the indigenous Bashkir population living in them, the preservation of their culture, traditions and customs, activating ethno-tourism and improving the quality of life of the villagers

Experience with ferrosilicoaluminum alloy during deoxidation of steel

The article describes the process of deoxidation quiet and low-alloyed steel alloy ferrosilicoaluminum complex in comparison the existing, and with steel deoxidation technology with conventional alloys - ferrosilicon and secondary aluminum. A comparative analysis of quality steel, non-metallic inclusions metallographic studies and studies of the mechanical properties of the resulting steel was done. On a large array of experimental steel proved cost-effectiveness and feasibility of ferrosilicoaluminum during deoxidation quiet and low-alloyed steel

Management of technical skills of highly qualified female athletes specializing in athletic jumps

Significant improvement of efficiency in managing technical mastery of female athletes-jumpers depend on the operational response to the emerging new technologies, their approbation and implementation in practice. The article introduces new opportunities for the use of simulators in the process of technical training of highly qualified female jumpers. The authors demonstrate the principal possibility of the applied use of the "facilitating-the-leadership" simulator for improvement of motor actions of female athletes. Obtained results show evident prospects of further expanding of the use of technology and simulators in the system of present-day preparation of highly skilled female athletes
