The participants of the study are represented by both sexes of different courses, from which the control and experimental groups were formed. The research methods used include the study and analysis of scientific and scientific-methodical literature, pedagogical experiments, surveys, testing, analyses, synthesis and generalisation of information, as well as methods of mathematical statistics. Results. At the beginning of the study, 93.33 % of students in the control group and 94.44 % of students in the experimental group had a low level of the practical component of readiness for educational activities contributing to sustainable development. The final stage of the study revealed a significant improvement in the studied indicator within the experimental group: 43.33 % of students demonstrated a low level of the practical component of the studied readiness, 16.67 % had a satisfactory level, 31.11 % showed an average level, and 8.89 % had a high level. The corresponding changes were observed in all defined indicators: activities for sustainable development in physical education classes or sectional sports lessons; activities for sustainable development during extracurricular work of a physical education teacher or outside the sectional work of a sports coach with a population of different age groups; and activities for sustainable development in managerial positions.
