The main objective of this study was the effect of physical exercise on the academic achievement of students at Bolomeda Secondary and Preparatory School. To accomplish this, a quasi-experimental design was employed. A sample of 40 students, aged approximately 20 years, was selected using a random sampling technique. The students were randomly assigned to either an experimental group or a control group. The experimental group engaged in physical exercise three days per week for a duration of three months, with each session lasting 40-60 minutes. Data collected from the participants were analyzed using SPSS version 21 software. The triangulation of paired and independent sample t-test results showed a significant improvement in academic achievement among the students in the experimental group, while no such improvement was observed in the control group. Based on ANCOVA results, gender does not have a statistically significant effect on the relationship between physical exercise and academic performance in this analysis. These findings suggest that physical exercise plays a positive role in enhancing students' academic performance. Given these results, physical exercise should receive greater attention both locally and globally and be considered a fundamental component in strategies aimed at improving students' academic achievement and attitudes towards physical education. However, further long-term studies with follow-up assessments are recommended to confirm these findings.
