Objective of the study was to experimental verification of the effectiveness of the influence of classes in the boxing specialization on the level of physical fitness of first-year students. Methods and structure of the study. The pedagogical experiment was conducted at the Peoples' Friendship University of Russia named after Patrice Lumumba over the course of one academic year. First-year students of the Faculty of Physics, Mathematics and Natural Sciences (n=450) took part in it. At the beginning of the academic year, the experimental (boxing) and control (GPT) groups were determined using a questionnaire, with 20 students in each group (n=20). Classes in the experimental group were held in the boxing specialization, where the main basic punches of a boxer were studied, which were supplemented by blocks on the development of special and general physical training. At the end of the academic year, boxing competitions were held to determine the winners among the students of the experimental group. In the control group, students were engaged in a general physical training (GPT) program. Results and conclusions. At the end of the experiment, more significant reliable changes in the level of physical fitness were obtained in the students of the experimental group (boxing). Based on the results obtained, it can be stated that classes in the experimental group using the boxing specialization more effectively affect the level of physical fitness of male students, which indicates the feasibility of using this type of sport in the framework of physical education classes at the university. In the experimental group (GPP), there were also reliable changes, but with a smaller tendency and not for all the indicators under consideration. © 2025, Teoriya i praktika fizicheskoy kul'tury i sporta.
