The platform architecture comprises technical, knowledge, operational-data, and user-application components supporting teaching assistance, exercise guidance, competition organization, and health-related information services. A formative campus deployment involving 428 students and six instructors documented implementation feasibility and user-facing application scenarios. To provide a more rigorous empirical supplement, an independent six-week, non-randomized, intact-class quasi-experiment was conducted with 196 students in four physical-education classes. Two classes received platform-supported instruction and two received conventional instruction from the same instructor. Baseline-adjusted analyses indicated higher posttest basic psychological need satisfaction in the platform-supported group (adjusted difference\u202f=\u202f0.618, 95% CI 0.506\u20130.730,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001) and lower need frustration (adjusted difference\u202f=\u202f\u22120.653, 95% CI \u22120.759 to \u22120.547,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001). The adjusted difference in self-reported physical activity was not statistically significant (\n                    <jats:italic>p<\/jats:italic>\n                    \u202f=\u202f0.216). These findings provide preliminary evidence of more favorable psychological-need experiences during platform-supported physical education, but do not indicate a corresponding increase in self-reported physical activity over 6\u202fweeks. The central contribution lies in the education-oriented integration of AI architecture, institutional knowledge resources, and classroom implementation evidence within a unified university physical-education platform.\n
