Objective of the study is to determine the effect of electromagnetic stimulation on improving the strength and speed-strength abilities of muscles in skilled sambo wrestlers.
Methods and structure of the study. The study was conducted from 2018 to 2020 at the country's leading sports university, RUS GTSOLIFK. 20 skilled sambo wrestlers aged 19 to 23 were divided into a control group and an experimental group of 10 people each. The athletic level of the wrestlers in each group was the same. Strength indicators were recorded from 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 mode of muscle contraction 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%.

Keywords: electromagnetic stimulation, strength abilities, speed-strength abilities, Biodex System Pro-4, athletes, sambo wrestlers.
