| Summary: | 碩士 === 國立中正大學 === 運動與休閒教育所 === 97 === This research is to study the association of Internet addiction, physical activity mass and emotion in senior high school students. The purposes of this study are: (1) to understand the correlations of Internet addiction, levels of physical activity, and emotion; (2) to discuss whether the background variables, levels of physical activity, and emotion could successfully predict Internet addiction; (3) to compare the emotional differences before and after exercises of senior high school students who have high or low Internet addicted behaviors. Methods: (1) questionnaires for senior high school students in Yunlin and Chiayi (948 available questionnaires, 722 male and 226 female; 30 subjects, 15 each for high and low degree of Internet addiction were recruited for the intervention); (2) an emotional effect experiment on students at one senior high school in Yunlin. Measuring instrucments were: (1) Chen Internet Addiction Scale, CIAS; (2) seven-day physical activity recall, 7-d PAR; and (3) senior high school students’ emotional intelligence scale. The data were analyzed by using Paired-Samples T Test, One-way ANOVA, Pearson Product-Moment Correlation Coefficient, and Stepwise Multiple Regression.
The main results were as follows:
1. the degree of Internet addiction of senior high school students has a significantly negative correlation with the physical activity levels; (2) the degree of Internet addiction of senior high school students has a significantly negative correlation with negative emotion; (3) the physical activity levels of senior high school students has a significantly positive correlation with positive emotional total scores and a significantly negative correlation with negative emotional total scores.
2. Sex, high academic achievement, negative emotion, and physical activity levels could effectively predict the degree of Internet addiction, and its explained variance reached 12.0%.
3. Internet addicted senior high students’ emotional differences among different intensities and stages of exercises: (1) for the intensity of free exercises of high degree of Internet addicts, the positive emotion after exercises is significantly higher than that before exercises; (2) for the intensity of free exercises of low degree of Internet addicts, the negative emotion after exercises is significantly higher than that before exercises.
4. The variances of emotional differences after exercises of different degrees of Internet addicted senior high school students for intensities of free and assigned exercises: (1) For high degree of Internet addicts, positive emotional variances for the intensity of free exercises are significantly higher than those for the intensity of assigned exercises; and negative emotional variances for the intensity of free exercises are significantly lower than those for the intensity of assigned exercises. (2) For low degree of Internet addicts, negative emotional variances for the intensity of free exercises are significantly lower than those for the intensity of assigned exercises.
The results of this research provide references for future studies on Internet addiction, physical activity, and emotion, and some guidelines of physical activity and emotion were suggested for those PE teachers.
