The influence of speed-strength training on the vestibular stability of children aged 13-14 years with different strength of the nervous system

Abstract

The aim is to determine the effect of speed-strength exercises on the vestibular stability of schoolchildren with different nervous systems. Research methods: The pedagogical experiment was conducted from January 12 to March 20, 2020 in Kirov, Russia, school number 60. The study involved children aged 13-14. 20 students from grade 7a and 20 students from grade 7b. Children from class 7a were engaged in the usual program, and children from class 7b additionally performed speed-strength exercises. Children from grade 7b were differentiated into two subgroups taking into account the strength of the nervous system, a «tapping test» was used. Vestibular stability of schoolchildren was measured using the test «Turns on the gymnastic bench». The data were analyzed using the Student's T-test. Results of the study: after the end of the pedagogical experiment, the indicators of vestibular stability in schoolchildren in all subgroups improved, but in different ways. In children from grade 7a, the indicators improved slightly, only by 6-7% (p>0.05). In schoolchildren from grade 7b, the indicators improved significantly. In children with a strong nervous system, the indicators improved by 21% (p>0.05), and in children with a weak nervous system - by 18% (p>0.05). Conclusion: if at each physical education lesson at school children will additionally perform speed and strength exercises, then the indicators of vestibular stability will improve. Physical activity should be differentiated taking into account the strength of the nervous system of schoolchildren.
