【摘要】 本研究聚焦锻炼动机对普通大学生体育锻炼行为的影响，以及锻炼自我效能在其中所起的中介效应。通过对267名普通大学生进行问卷调查，运用相关性分析、回归分析等统计方法，结果显示：锻炼内部动机与大学生的体育锻炼行为呈显著正相关，即较强的锻炼内部动机能够显著促进学生积极参与体育锻炼。同时，锻炼自我效能在二者关系中发挥了部分中介作用，表明锻炼动机不仅直接影响学生的锻炼行为，还通过增强学生的锻炼自我效能，间接提升其参与体育锻炼的积极性和持续性。研究结论为高校体育教育工作者制定科学有效的干预策略，提高大学生体育锻炼参与度提供了理论依据与实践指导。更多还原

【Abstract】 This research examines how exercise motivation influences students’ engagement in physical activity of non-sports major students, as well as the mediating effect of exercise self-efficacy. Through a questionnaire survey of 267 non-sports major students and using statistical methods such as correlation analysis and regression analysis, the results show that exercise intrinsic motivation is significantly and positively correlated with the physical exercise behavior of non-sports major students. That is, stronger exercise intrinsic motivation can significantly promote students’ active participation in physical exercise. At the same time, exercise self-efficacy plays a partial mediating role in the relationship between the two, indicating that exercise motivation not only explicitly influences students’ physical activity but also implicitly enhances their participation in physical exercise and its sustainability by increasing their exercise self-efficacy. The research conclusions provide theoretical basis and practical guidance for college physical education workers to develop scientific and effective intervention strategies to improve the participation rate of non-sports major students in physical exercise.更多还原
