【摘要】 目的:基于运动承诺模型,检验运动承诺在社会支持与城市中年人身体活动行为之间的中介效应,探讨城市中年人身体活动影响因素及机制。方法:选取某城市中年人550人发放问卷,有效问卷505份。其中(男282人,Mage=(40.44±1.57);女223人,Mage=(39.01±1.39)。测量工具:《社会支持量表》、《运动承诺量表》、《国际体力活动量表-7》,数据处理采用SPSS20.0,。结果:社会支持、运动承诺、身体活动之间均有显著的正相关;采用逐步回归分析发现,社会支持对城市中年人身体活动产生影响的回归系数显著(β=0.344,=0.000),并解释了12%的身体活动变异;社会支持、运动承诺对身体活动的产生影响回归系数显著(β=0.531,=0.000),并解释了17%的身体活动变异,且决定变化系数?2=0.05。中介效应检验结果显示,中介效应检验显著,且运动承诺的中介效应占总效应的比值为12.66%。结论:社会支持、运动承诺、身体活动行为之间均称显著正相关;社会支持对城市中年人的身体活动行为有直接显著的预测作用;运动承诺在社会支持与城市中年人身体活动行为之间起着部分中介作用。建议:研究结果提示,城市中年人在参与体育锻炼的过程中,不仅要给与他们更多的社会支持和鼓励,提高他们参与体育锻炼的动机和积极性,同时还要给与他们参与体育锻炼的机会和选择权、自主权,增强和维系锻炼动机,应该帮助锻炼者选择自己感兴趣的锻炼方式和运动项目,激发锻炼者的积极情感体验,体验锻炼所带来的乐趣,增加成功体验。更多还原

【Abstract】 objective: based on the sports commitment model, to examine the mediating effect of sports commitment on social support and physical activity behaviors of middle-aged urban residents, and to explore the influencing factors and mechanisms of physical activity of middle-aged urban residents.Methods: 550 middle-aged people in a city were selected and 505 valid questionnaires were distributed.Among them(282 males, Mage=(40.44±1.57);Female 223, Mage=(39.01±1.39).Measurement tools: social support scale, exercise commitment scale and international physical activity scale-7. SPSS20.0 was adopted for data processing.Results: there were significant positive correlation among social support, sports commitment and physical activity.Stepwise regression analysis showed that the regression coefficient of social support on physical activity in middle-aged urban residents was significant(beta =0.344, p=0.000), and explained 12% variation of physical activity.Social support and exercise commitment have significant effects on physical activity(beta =0.531, p=0.000), which explains 17% variation in physical activity and determines the variation coefficient delta R^2=0.05.The mediating effect test results showed that the mediating effect test was significant, and the mediating effect of exercise commitment accounted for 12.66% of the total effect.Conclusion: there were significant positive correlations among social support, exercise commitment and physical activity behavior.Social support has a direct and significant predictive effect on physical activity behavior of middle-aged urban residents.Sports commitment plays a part of mediating role between social support and physical activity behaviors of urban middle-aged people.Suggestion: the results suggest that urban middle-aged people in the process of participating in physical exercise, not only to give them more social support and encouragement, and taking part in physical exercise to improve their motivation and enthusiasm, as well as giving them a chance of taking part in physical exercise and options, autonomy, enhance and sustain exercise motivation, should help exercisers choose their interested in exercise and sports, motivate exercisers positive emotional experience, experience brought about by the fun and exercise increase successful experience.更多还原
