摘要：The paper is devoted to the issues of improving the methods of physical training.
Currently, the method of teaching and training schoolchildren is developed mainly
with a focus on a child's age, which does not always correspond to his or her
biological maturity. These reasons together with the growing phenomenon of child
acceleration reinforce the relevance of the research topic. The purpose of the study
is to evaluate the impact of speed-strength exercises on the physical development
and speed-strength qualities of schoolchildren aged 11-12. The authors used the
measurements of anthropometric and physiometric indicators, as well as the tests
that determine the level of development of speed and speed-strength qualities. The
results of the research show that the physical indicators of the test group tend to
increase, and during the school year, many indicators significantly change.
