Objective of the study was to analyze the effect of deep jumps on the manifestation of power and the generation of strength in qualified martial artists involved in judo and sambo.
Methods and structure of the study. The experiment was attended by 10 athletes specializing in judo and sambo wrestling, with sports qualifications "Candidate for Master of Sports" and "Master of Sports of Russia". In the experimental program, the athletes did deep jumps from a dosed height of 50 cm, followed by long jumps. Each jump was performed with a concentration on achieving maximum effort. The work was carried out serially, five jumps in a series with a rest between series of 2 minutes. The subjects performed this load three times a week. The tests were performed in the laboratory on a Monark bicycle ergometer (Sweden) and a dynamographic simulator.
Results and conclusions. As a result of the training program, there was a significant improvement in such indicators as maximum power (by 7.1%), peak power (by 11.1%), time to reach maximum power (by 22.4%), time to reach 97% of maximum power (by 27.8%). As a result of the work done, the values of the maximum force and the time to achieve it have improved. The plyometric mode of operation can be recommended for inclusion in the training process of athletes in order to develop the maximum power of the alactic anaerobic process of energy supply and improve the speed of its deployment.

Keywords: deep jumps, muscle strength and power, isometric muscle contractions, bicycle ergometry, Wingate test.
