The study investigated the roles of advanced digital tools in enhancing engagement with physical education among undergraduates. The focus was on the effects of digital monitoring and real-time feedback technologies on increasing physical activity participation and improving physical fitness levels of undergraduates. Throughout a semester, the activity of 8,556 students was observed through a rigorous experimental setup. For data analysis, the study used the Mann-Whitney U test, Kruskal-Wallis H test, Spearman's rho test, and generalised linear models. The outcomes indicated a notable uptick in physical activity participation among students who were conscious that their activity was being digitally tracked. Additionally, the provision of instant feedback not only increased students' engagement in their selected sports but also helped maintain their long-term commitment. These technological interventions led to a significant improvement in the physical fitness levels of the students involved. The conclusions drawn from this research offer valuable guidance to educational policymakers and public health officials aiming to promote physical fitness in the youth population. The research suggests continued exploration into refining digital monitoring tools to maximise their effectiveness in physical education settings.
