Abstract:
The aim is to determine the effect of speed and strength training on the intellectual abilities of children aged 1314 years, taking into account the strength of their nervous system. Methods: the pedagogical experiment took place in a school (Kirov, Russia) and lasted for 3 months. The study involved 40 children aged 13-14 years, who studied in the 7th grade. Children from the control group were engaged in the usual physical education program at school. Children from the experimental group were engaged in the usual program, but additionally performed exercises to develop speed and strength abilities. The load was differentiated taking into account the strength of the schoolchildren nervous system. The tapping test determined the strength of the schoolchildren nervous system. "Choose unnecessary" determined the indicators of intellectual abilities of schoolchildren. Results: after the study, the indicators in all subgroups improved, but in different ways. In schoolchildren with a strong nervous system in CG, the indicators of intellectual abilities improved from 7.1±1.1 to 7.5±1.0, the increase in indicators was only 6%. In children with a weak nervous system, the indicators improved from 7.5±1.0 to 8.1±1.0, and the increase in intellectual abilities was 8%. At the same time, the results in the EG in both subgroups were much more significant. Thus, in children with a strong nervous system, the indicators improved from 7.4±0.7 to 8.5±0.8, an increase of 17%. And in children with a strong nervous system, the indicators improved from 7.7±1.2 to 9.2±1.4, an increase of 20%. Conclusion: the indicators of intellectual abilities of schoolchildren aged 13-14 years will improve if they perform physical exercises aimed at developing speed and strength abilities at each physical culture lesson at school. At the same time, the physical activity for children with a strong and weak nervous system should be differentiated according to the process of arousal.
