摘　　要：为了解当代大学生的生命质量及其影响因素,探索身体锻炼对大学生生命质量的影响机制。运用整群抽样方法从不同地区选取六所高校中的822名在校大学生进行调查,并构建以主观锻炼体验与领悟社会支持为中介的模型,通过中介效应检验,探索促进大学生生命质量的内在规律。结果显示:大学生生命质量在性别、专业、身体锻炼层面均具有非常显著性差异(P<0.01),恋爱状况与生源地分别在社会关系与环境支持维度存在显著性差异(P<0.05);身体锻炼、生命质量、主观锻炼体验和领悟社会支持各维度两两间非常显著相关(P<0.01)。身体锻炼对生命质量的正向预测作用非常显著(B=0.15,t=4.05,P<0.01),对主观锻炼体验(B=0.26,t=6.88,P<0.01)和领悟社会支持(B=0.10,t=2.84,P<0.01)的正向预测作用也非常显著;主观锻炼体验及领悟社会支持在身体锻炼与大学生生命质量间的95%置信区间为[0.031,0.069]。结论:主观锻炼体验及领悟社会支持在身体锻炼与大学生生命质量间具有完全链式中介作用,影响大学生生命质量的基础因素是身体锻炼,但关键因素是在锻炼后产生的主观体验及感受到的社会支持程度,需将三者看作促进大学生生命质量的整体。In order to understand the quality of life of contemporary college students and its influencing factors,explore the mechanism of the impact of physical exercise on the quality of life of college students.Using the cluster sampling method to select 822 college students from six universities in different regions for investigation,and construct a model that uses subjective exercise experience and social support as an intermediary.Through the intermediary effect test,explore the internal laws that promote the quality of life of college students.The results show that the quality of life of college students has significant differences in terms of gender,major,and physical exercise(P<0.01),and the relationship between love status and birthplace has significant differences in social relationship and environmental support dimensions(P<0.05).Physical exercise,quality of life,subjective exercise experience,and comprehension of social support are significantly related to each other(P<0.01).The positive effect of physical exercise on quality of life is significant(B=0.15,t=4.05,P<0.01),subjective exercise experience(B=0.26,t=6.88,P<0.01)and comprehending social support(B=0.10,t=2.84,P<0.01)also has a significant positive prediction effect.The 95%confidence interval between subjective exercise experience and comprehending social support between physical exercise and the quality of life of college students is[0.031,0.069].Conclusion:Subjective exercise experience and comprehending social support have a full chain intermediary effect between physical exercise and the quality of life of college students.The basic factor that affects the quality of life of college students is physical exercise,but the key factor is the subjective experience and feelings generated after exercise The degree of social support needs to be considered as a whole that promotes the quality of life of college students.
