Objective of the study is to investigate the effect of electromagnetic stimulation on the development of strength and speed-strength abilities in skilled sambo wrestlers. Methods and structure of the study. The study was conducted between 2018 and 2020 at the country's leading sports university, the Russian University of Sport «GTSOLIFK». 20 qualified sambo wrestlers aged 19 to 23 took part in the study and were divided into a control group and an experimental group of 10 people each. The athletic level of the wrestlers in both groups was comparable. Strength indicators were recorded in a sitting position using the Biodex System Pro-4 hardware and software complex (Figure 1) in isometric muscle contraction mode with parallel recording of the electromyogram of the working muscles. Results and conclusions. The results of the analysis of the data obtained showed that performing exercises on the Biodex System Pro-4 hardware and software complex in isokinetic muscle contraction mode during a short training period increases strength and speed-strength abilities. In the group where electromagnetic stimulation was not used, the increase in strength indicators was 14.8% and 14.1%, and in speed-strength indicators - 11.6%. In the group where the exercise was accompanied by electromagnetic muscle stimulation, the increase in strength indicators was 32.3% and 34.1%, and in speed-strength indicators - 54.2%.
