We all know the importance of self-image in the management of everyday tasks arising from the dynamics of changes in modern society, which involves consistent coping skills and increased resistance to effort and stressors; thus, a strongly positive self-image enhances coping skills, and life obstacles are perceived as challenges to be overcome in order to achieve the intended goals. The purpose of our paper is to highlight the impact of aerobic exercise performed for 16 weeks on the self-image of young women aged between 19 and 24 years, students at different faculties within the "Politehnica" University of Bucharest (UPB). The research was conducted on a sample of 62 girls, of whom 31 were part of the experiment group that participated in an aerobic exercise programme performed 3 times a week, over a 16-week period; the control group was also made up of 31 girls in the final years of study at UPB, but their curriculum did not provide sports activity classes and they did not practice physical exercise independently; however, some of them used to practice sporadically different physical activities. The systematic practice of aerobic exercise had a positive impact on the self-image of the physical and mental Ego for the girls in the experimental group, with statistically significant differences, as shown by the statistical processing.
