Background: This study aimed to determine the effect of speed-strength exercises on the vestibular stability of schoolchildren with different nervous systems.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. The participants from class 7a were considered as the control group, being engaged in the usual program; and those from class 7b additionally performed speed-strength exercises. Children from grade 7b were divided into two subgroups taking into account the strength of their nervous systems, determined based on a «tapping test». Vestibular stability of schoolchildren was measured using the test of «Turns on the gymnastic bench». The data was analyzed using the Student's T-test.Results: After the end of the pedagogical experiment, the indicators of vestibular stability in schoolchildren in all subgroups were improved, but in different ways. In the control group, the indicators were improved slightly, only by 6-7% (p>0.05). However, in the experimental groups 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
