Розвиток швидкісно-силових якостей дівчат під час занять з аеробіки в позашкільних навчальних закладах

Abstract

У статті розглядається вплив занять з аеробіки на розвиток швидкісно-силових якостей дівчат 16-18 років.

В статье рассмотрено влияние занятий по аэробике на развитие скоростно-силовых качеств девушек 16-18 лет.

Purpose: to determine the influence of aerobics classes on the development of speed-strength qualities of girls aged 16-18. Material: the study involved 90 girls aged 16-18 (60 girls in the health group and 30 in the athletic group).Results: As a result of a comprehensive study of girls in the health group and the athletic group, who do aerobics in extra-scholastic establishments, a large number of motor preparedness indicators that were ordered by the means of modeling and building models methods, which allow us to reveal fuller and deeper the essence of the studied phenomenon is received. In the study of biodynamic parameters a large number of support reactions indicators at jumping up in the grouping were recorded. As a result of the studies the principal strain-dynamo-graphical indicators among the girls in the general group and the girls in the athletic group and the difference between them are discovered: Fz max 63,44%, Fx max 60,49%, Fy max 64,48%, F max 62,72%, F max / P 60,83%, GRAD 69,87%, I 65,18%, Tps -60,00%, Tmax -57,35%, To -39 13%, Th 46,34%, Hmax 50,00%, Tsum -46,63%. In the result of the introduction to education process the methodic of conducting aerobics classes among girls in extra-scholastic establishments developed based on graph-analytic models positive changes in speed-strength indicators took place. Within the control group the indicators improved on average by 7.5% and in the experimental group by 19.8 % (p <0,05) Conclusions: The received data has allowed to identify leading criteria for girls’ speed-strength preparedness indicators to facilitate more thorough study of the impact of aerobics classes at overall development of girls. Also, based on biomechanical models, it is possible to make a correction of girls’ motor preparedness, control speed-strength qualities during aerobics classes.
