Influence of Speed-Power Abilities on Memory in Children with Different Strength of the Nervous System

Background the aim of this study is to determine the effect of speed-strength training on memory in schoolchildren aged 13-14 years, taking into account the strength of their nervous system. materials and methods this case control study was conducted in a secondary school in the city of kirov in russia for a period of 3 months (january 12 to march 20, 2020). 40 boys and girls were engaged in physical education 2 times a week for 40 minutes. 20 schoolchildren from the control group were engaged in physical education according to the usual program. 20 schoolchildren from the experimental group additionally performed exercises for the development of speed and strength abilities. the strength of the nervous system was determined using a tapping test. memory indicators in children were measured using the «method of jacobs» test. data were analyzed using spss software version 16.0. results 40 children participant in this study. after the pedagogical experiment, the indicators in all subgroups changed. in the control group, memory indicators in children with a strong nervous system improved only by 5% (p>0,05), and in children with a weak nervous system from 5.5±0.5 to 5.7±0.5, this is only 4% (p>0.05). at the same time, in the experimental group of children with a strong nervous system, memory indicators improved by 21% (p <0.05), and in children with a weak nervous system from 5.1±0.7 to 6.0±0.9, this is 18% (p <0.05). conclusion memory performance in children aged 13-14 years will improve if we perform speed-strength exercises at each lesson in physical culture. the load for children with a strong and weak nervous system should be differentiated.
