This study examined the role of self-efficacy as a central mechanism linking athletes’ profiles and sports participation experiences to academic performance and character development. Using a descriptive research design, data were collected through observation and surveys from 143 student-athletes from the University of Perpetual Help System-Laguna. Surveys were conducted via Google Forms. Data were analyzed using frequency count, percent distribution, mean, standard deviation, Pearson correlation, multiple linear regression, and mediation analysis.

       Self-efficacy was conceptualized through self-regulation, goal orientation, and identity balance, highlighting how athletes’ confidence in managing dual roles as students and competitors shaped positive outcomes, as indicated by a strongly agree with an overall mean of 4.53. Independent variables included athletes’ demographic and athletic profiles such as age, gender, year level, years of athletic experience, and sport played, alongside sports participation factors including engagement, training intensity, competition level, skill training, and conditioning activities. The study proposed that these independent variables significantly influenced self-efficacy, which in turn exerted a direct and positive effect on key dependent variables.

         Academic performance outcomes encompassed academic standing, effective integration of studies and training, and active classroom engagement, which were rated as very satisfactory with a mean of 4.34. Concurrently, character development outcomes emphasized discipline, teamwork, time management, and leadership skills. Through consistent sports involvement and structured training environments, athletes developed adaptive self-regulation strategies, clearer goals, and a balanced identity, enabling them to excel both academically and personally.

          Overall, this study underscored the synergistic benefits of sports participation when supported by strong self-efficacy. It suggested that well-designed athletic programs not only enhanced physical competencies but also promoted academic success and holistic character growth. By positioning self-efficacy as a mediating construct, the framework provided a positive, strengths-based perspective on student-athletes, affirming that engagement in sports served as a powerful avenue for developing resilient, disciplined, and well-rounded individuals capable of sustaining high performance across educational and athletic domains in higher education.
