Introduction. The intensity of physical work reflects the internal side of the load, determined by the degree of activation of functional systems, including the lactate system. The article presents the results of a remote control training, the purpose of which was to develop the energy potential in middle-distance running. Due to the fact that the ability to perform a given load at high concentrations of lactate is a characteristic feature in the preparation of an average athlete, the purpose of our study was to identify the content of lactate in the blood of qualified middle-distance runners when performing a specific load and its impact on the competitive result. Methodology and organization of the study The lactate content in the blood was determined using an Accutrend Plus lactometer. The level of lactate in the blood was measured after the first segment, and after the first and second series. The study was conducted on the basis of FGBOU VO "Povolzhsky GUFKSiT". The study involved qualified middle-distance runners aged 18 to 24 years. Results of the study and their discussion. Table 1 presents the results of remote control training, Figure 1 shows the graph of the dynamics of the lactate curve change, and Table 2 shows the correlation matrix the relationship between the lactate level and the running time of segments (400 m). Conclusions. Based on the results obtained, we recommend that athletes and their coaches, in order to improve the competitive result with the help of concentrated remote work, reach those values of lactate in the blood that should be close to the competitive ones. This concept is reflected in our experiment (Xav±o) of 16.8 mmol/1, which is 2.3% less than after running 1500 meters in competition
