The impact of a structured sports activity program on physical fitness and mental health among secondary school students

Aim. This study examined the effects of a structured sports activity program on physical fitness and mental health among secondary school students.

Methods. A quasi-experimental pre-post design was conducted with 120 students divided into intervention and control groups. The intervention group followed a 12-week structured sports program (3 sessions/week). Physical fitness was measured using standardized tests, and mental health was assessed using validated psychological scales. Data were analyzed using descriptive and inferential statistics.

Results. Cardiorespiratory endurance increased by 23.4%, upper body strength by 31.2%, core strength by 28.7%, and flexibility by 18.6% in the intervention group (p < 0.001). Depression (−42.3%), anxiety (−38.7%), and stress (−35.9%) decreased, while self-esteem (+27.4%) and well-being (+33.8%) improved. The control group showed minimal changes.

Conclusion. The structured sports program significantly improved physical fitness and mental health outcomes, supporting its integration into secondary school physical education curricula.
