Comparative Analysis of School Physical Education Models and Student Fitness

Thesis Abstract

This study addresses the persistent concern that disparate models of school physical education (SPE) contribute to uneven student fitness outcomes across diverse regions, particularly where curricular diffusion and resource constraints shape implementation. The aim is to compare the effects of three SPE models—traditional sport-centric, health-centered activity curricula, and integrative fitness and motor-skill development programs—on student fitness indices and psychosocial correlates. Specific objectives are (1) to quantify differences in physical fitness components (cardiorespiratory endurance, muscular strength, flexibility, body composition) across SPE models; (2) to examine how instructional time, teacher qualifications, and facility access mediate these relationships; (3) to assess student motivation, enjoyment, and self-efficacy as mediators between SPE models and engagement in physical activity outside school; and (4) to identify contextual factors that influence model effectiveness in urban, suburban, and rural schools. A cross-sectional, multi-site design will be employed, sampling 60 secondary schools (20 per SPE model) across three districts. Within each school, 15–25 students aged 12–15 years and two SPE teachers will be selected, yielding a total student sample of approximately 1,200 and 120 teachers. Data collection will involve standardized fitness testing ( EUROFIT/ACSM protocols), anthropometric measurements, and instruments for motivation and self-efficacy (Intrinsic Motivation Inventory, Self-Efficacy for Exercise Scale). Teaching and environmental variables will be captured via structured school inventories and classroom observations using a validated SPE model rubric. Data analysis will consist of multilevel linear modeling to account for clustering at the school level, followed by mediation analyses to explore indirect effects of psychosocial factors on fitness outcomes. ANOVA will compare group means across SPE models for key fitness indicators, and hierarchical regression will assess the contribution of mediators and contextual covariates. Qualitative data from teacher interviews (n = 30) and focus groups with students (n = 6 groups per district) will be analyzed thematically to triangulate quantitative results and elucidate implementation mechanisms, guided by a theoretical framework integrating Self-Determination Theory and Social Cognitive Theory. The study anticipates that integrative SPE models combining motor-skill development with sustained health-focused activities will yield superior improvements in cardiorespiratory fitness and body composition, while also enhancing intrinsic motivation and autonomous self-regulation for ongoing physical activity. Health-centered models are expected to produce moderate gains in aerobic capacity with stronger effects on health literacy and long-term engagement, whereas traditional sport-centric models may yield mixed fitness outcomes dependent on access to facilities and opportunities for inclusive participation. The research contributes to knowledge by providing robust, cross-context evidence on how SPE model design and implementation influence both physical and psychosocial student outcomes, and by identifying district- and school-level factors that optimize effectiveness. The findings will inform curriculum policy, teacher professional development, and resource allocation decisions aimed at reducing fitness disparities and promoting equitable physical education experiences. Conclusion emphasizes the need for intentional alignment of SPE models with available resources and student needs, recommending a phased implementation approach that prioritizes integrative, enjoyment-oriented curricula, enhanced teacher training in inclusive instruction, and ongoing monitoring of fitness and engagement indicators. Policy implications include endorsing model-specific professional development modules, standardized assessment frameworks, and investment in facilities and equipment to support consistent, high-quality SPE delivery across diverse school contexts.
