The purpose of the study is to test and implement a set of physical exercises for developing the strength and speed abilities of students, as well as to test the effectiveness of the differentiated method in physical education lessons, taking into account the type of nervous system in the learning process. All students must perform 3 control tests: a long jump from a standing position (cm), lifting the trunk from a lying position (20 seconds), flexion, and extension of the arms while lying on the floor (20 seconds). The students were given the task to pass a tapping test. The indicators of the control group did not significantly improve from 4% to 6% after the end of the pedagogical experiment. In the experimental group - 1, the indicators improved from 9% to 14% during the experiment period. In the experimental group - 2, the indicators significantly improved in children with a strong nervous system from 12% to 16% and schoolchildren with a weak nervous system from 13% to 19%. If you perform a set of physical exercises for the development of strength and speed abilities in physical education classes, then the indicators of such abilities will improve. If you perform a set of exercises with a differentiated load, taking into account the strength of the nervous system, then the indicators of speed and strength abilities will significantly improve.
