Final summary of hypothesis testing outcomes.

This study evaluated the effectiveness of an app-supported training model versus conventional physical education (PE) on college students’ basic athletic abilities and described exercise motivation in the app-supported condition. A quasi-experimental study was conducted with 90 freshman students over a 10-week period. Participants were assigned to a Treatment Group (n = 45), using the “Campus Sports World” app for guided extracurricular training, and a Control Group (n = 45) following traditional instruction. Physical fitness was assessed pre- and post-intervention using standardized tests for speed, endurance, explosive power, and flexibility. Motivation was assessed post-intervention in the Treatment Group via a questionnaire based on Self-Determination Theory. Results indicated that the Treatment Group achieved significantly greater improvements in speed, explosive power, and flexibility compared to the Control Group. However, no significant difference was found in endurance performance. Furthermore, students in the Treatment Group reported high levels of both intrinsic and extrinsic motivation. These findings suggest that integrating mobile applications into college PE can enhance skill-related fitness, and the observed motivation profile provides context for students’ engagement with the app-supported model, supporting the adoption of blended learning approaches in higher education.本研究对比评估了应用程序（app）支持的训练模式与传统体育（Physical Education，PE）对大学生基础运动能力的提升效果，并描述了该应用支持模式下的运动动机水平。本次研究采用准实验设计，招募90名大一学生开展为期10周的实验。参与者被分为两组：实验组（n=45），使用"Campus Sports World"（校园体育世界）应用开展课外指导训练；对照组（n=45），采用传统体育教学模式。干预前后，研究人员通过针对速度、耐力、爆发力与柔韧性的标准化测试对受试者的身体素质进行评估。仅针对实验组，研究人员在干预后采用基于自我决定理论（Self-Determination Theory）的问卷对其运动动机进行测评。结果显示，相较于对照组，实验组在速度、爆发力及柔韧性三项指标上的提升幅度显著更高，但两组在耐力表现上无显著差异。此外，实验组学生报告其内在动机与外在动机均处于较高水平。本研究结果表明，将移动应用程序融入高校体育教学可有效提升与运动技能相关的身体素质，本次观测到的动机特征可为学生参与应用支持型训练模式提供情境解释，支持混合学习模式在高等教育领域的推广应用。
