The purpose of the study was a comparative analysis of training programs in bodybuilding and an assessment of their influence on the frequency of traumatization of the musculoskeletal system of athletes. Materials and methods. Theoretical analysis of scientific and methodological literature was conducted. For a practical assessment of the primary data on the types of injuries, a survey of medical staff was conducted. We analyzed 54 journals with records of athletes' appeals to medical personnel. Mathematical processing of research results was carried out using the software packages IBM SPSS Statistics 2.0. The study, which was conducted during 4 months – from March to the end of June 2021, involved 60 bodybuilders aged 18-19 years old. Three research groups of 20 athletes each were formed. They were divided according to age, qualifications and anthropometric characteristics. The created groups did not have significant differences in these characteristics; the intergroup difference applied only to the proposed training programs. Results and discussion. In the course of the study, it was found that among the athletes of the control group who used the generally accepted program of training sessions with a certain sequence of using exercises of a basic and formative nature, the number of calls with certain pain sensations during four mesocycles of training decreased by 30.7% (p <0.05) compared to a similar period before the start of the study. At the same time, the results obtained show that among the athletes of the first main group, who used the combined program of training sessions in bodybuilding during the study, the controlled indicator of the number of calls decreased significantly – by 33.4% (p <0.05). Conclusion. In the process of studying the peculiarities of the influence of various programs of training sessions on the dynamics of morpho-functional indicators of the athletes’ organisms during four mesocycles of training sessions, a certain regularity was established regarding the ratio of the manifestations of types of injuries when performing strength exercises, depending on the sequence of their use. In the process of applying the methodical procedure "premature fatigue" on the dynamics of morphometric indicators of body weight of athletes it is shown that it is the third version of the program that contributes to a significant decrease in the number of calls (by 75%, p <0.05), compared with the results obtained over the period of the previous four mesocycles of intensive bodybuilding at the stage of specialized basic training of athletes
