Experimental Study On The Promotion Of Physical Activity Of College Students From The Perspective Of Ecological Model Of Health Promotion

Objective: The aim of this study was to explore the intervention effect of health promotion ecological model on college students' physical activities,and to verify the intervention effect of ecological model,on the basis of ecological model and practice intervention of comprehensive factors.Methods: This study selected 328 people from 25 majors.The subjects were asked to have no major changes in physical activity in the last three months.They were randomly divided into two groups: A and B.Six intervention groups intervened according to the experimental intervention.In group A,the intervention model of ecological model was implemented,and group B did not take any intervention as the control group,and the intervention was carried out for 5 months.Before and after the experiment,the students' physical health data were measured,and the exercise IPAQ questionnaire was used to measure the physical activity,and the pedometer was used as the standard of the physical activity evaluation.Statistical analysis of the test data was carried out using IBM Statistic SPSS19.0 statistical software.The physical activity and physical fitness data of the students before and after the intervention were analyzed by ANOVA,and the homogeneity was tested.Paired-T test was used to evaluate the physical activity and physique test before and after the intervention.The experimental data were averaged ± standard deviation(M ± SD)the results were analyzed by Kappa statistical analysis.The Ridit analysis was used to compare the physical activity grading between the intervention group and the control group.The significance level was ? = 0.05.Results: Compared with the control group,the T-test results of physical health data and scores showed significant differences between the model intervention group and the control group.The Ridit analysis results of the BMI index showed significant differences between the two groups.The results of analysis of variance of the scores of physical fitness test showed that there were significant differences in intervention measures.Before and after physical activity data of the model intervention group and the control group,the T test showed that there was significant difference between before and after physical activity in the model intervention group,while there was no significant change in the control group.Ridit analysis showed that there was significant difference between model intervention group and control group,and model intervention was effective in promoting physical activity.The results of the analysis of variance of physical activity showed that there were significant differences among groups,and further multiple comparisons showed that there was significant difference between model group and each group.Conclusion: The ecological model of health promotion has a positive effect on the physical health and physical activity of college students,and has a positive effect on the BMI index and cardio respiratory endurance.Model intervention has a good effect on students' healthy lifestyle,which can promote students to reduce sedentary time,adopt positive mode of transportation,enhance physical health and increase daily physical activity.Health promotion of the ecological model can effectively promote the physical health of students and physical activity.
