<![CDATA[Background. Physical activity among sports science students is often assumed to support various aspects of personal development, although intensive academic and practical workloads may produce different effects on cognitive, psychological, and academic outcomes. Objective. This study examined the effects of physical activity on cognitive function, self-concept, and academic performance. Method. A quantitative correlational design was employed involving 97 undergraduate Sports Science students at Surabaya State University (69 males and 28 females). Data were collected using the International Physical Activity Questionnaire (IPAQ), cognitive function and self-concept instruments, and cumulative grade point average (CGPA). Simple linear regression was used to analyze the effect of physical activity on each dependent variable. Results. Physical activity significantly affected cognitive function (p = 0.006; F = 7.878; R² = 0.077; B = 0.160), but had no significant effect on self-concept (p = 0.394; F = 0.732) or academic achievement (p = 0.551; F = 0.599; R² = 0.004). Conclusion. Physical activity supports cognitive function but does not predict self-concept or academic achievement, highlighting the importance of promoting regular physical activity to enhance students' cognitive performance.]]>
