Abstract
Background
The aim of this study was to determine the influence of speed and strength abilities of children aged 13-14 years on the indicators of speed of movement, taking into account the differentiated physical activity, which is based on the strength of the nervous system.
Materials and Methods: This case-control study was conducted in an ordinary school in Russia, 40 seventh-graders took part in the experiment. Children from the control group (n=20) were engaged in the usual program, and children from the experimental group (n=20) additionally performed speed-strength exercises at each physical education lesson. Physical activity for children in the experimental group was differentiated, taking into account the strength of the schoolchildren nervous system. All schoolchildren took tests: tapping test, speed-strength abilities were determined by three tests. The speed of movement of schoolchildren was determined by the test «Running on the spot». Two results of two groups were compared.
Results: After the pedagogical experiment, the indicators for all tests in all subgroups increased. In the control group, the indicators of speed and strength abilities in both subgroups improved by 2-4% (p>0.05), and the indicators of speed of movement by 4-6% (p>0.05). At the same time, the children from the experimental group the indicators of speed and strength abilities improved by 11-16% (p <0.05), and the indicators of speed of movement improved by 17-19% (p <0.05).
Conclusion
After focused work in physical education classes at school on speed and strength abilities the indicators will improve not only speed-power abilities, but also increase the speed of movement taking into account the typology of the nervous system of schoolchildren.
