Abstract des Autors

Throwing action is one of the key motor actions children study at school. They refer to the basic motion types and are in the school curriculum of physical education starting from the first form. Throwings have an applied role and are used in everyday life and labor activity, in training military men of the Russian Army. Throwings are used in various outdoor games, relay races, render all-round effect on schoolchild's body and facilitate his harmonious development. Some research works contain the information on formation of the kinetic structure of small ball distance throwing by schoolchildren aged 8-10 and 10-12 in view of their age and sex differences etc. Similar results of the researches are made in the younger school age and of interest regarding the study of age specifics of formation of kinetic structure of displacement motion. The purpose of the research was to study sex features of kinetic structure of small ball distance throwing in the pupils aged 7-8. The analysis of subjective evaluation of tension of shown physical properties most remarkable for elite windsurfers while coping with the whole competitive route has revealed a wider (as compared with the previous data) variance range between the studied indices on single parts of the route in view of wind force and water state. Kinetic structure of throwing motion was proved to be better formed in 7-8-year-old boys compared to girls. Verf.-Referat
