Purpose:
The aim of this study was to examine the relation between using mobile virtual community, physical activities and health-related physical fitness of junior high school students.
Methods:
The subjects of the study were recruited from students in a certain junior high school in Taichung. A cross-section survey was conducted on 301 students stratified by grades. The questionnaire was divided into four sections: mobile virtual community(MVC), the international physical activities questionnaire, health-related physical fitness (HRPF), and background information. There were 280 valid questionnaires and the effective response rate was 93.0%. The data was analyzed by SPSS 17.0 and statistical methods including descriptive statistics, independent t-test, one-way Anova, Pearson product-moment correlation coefficient and multiple hierarchical regression analysis.
Results:
83.9% junior high school students used their own mobile phones surfing the net and 60% of them got unlimited data plan. They used MVC such as Facebook or Line 5.66 days per week and 1.5 hours for each time on weekdays and 3.5 hours for each time on weekends. As for the intention, 63.2% were related to social activities, including chatting with friends, and browsing posts from others. 36.8% were for leisure activities, including asking friends out for shopping or seeing a movie. In terms of physical activities, 22.5% students partipated in low-intensity exercise while 77.5% students partipated in moderate or high-intensity exercise. About 28.3% students would do outdoor activities during the break; however, 43.3% to 48.1% students were not used to exercise after class or after dinner. Roughly three quarters (75.4%) of Taiwanese junior high school students reached 4 standards of HRPF. All items are above 25th percentile. Physical activities and HRPF had significant correlation. HRPF could be predicted by analyzing physical activities and the use of MVC. The predictability was 39.2%.
Conclusion:
Junior high school students with moderate or high intensity of participating in physical activities and less use of MVC had better performance in HRPF. These findings suggest that government should focus on developing friendly area for exercising, offering more leisure activities for free or with reasonable prices. In addition, announcing public information through Facebook or Line can attract teenagers to go exercising in groups. Schools should promote exercise, execute SH150 policy, and encourage students to build up the habit of exercising. Combined with the design of the curriculum, the interventions should focus on strengthening fitness knowledge and sports skills to make students exercise voluntarily and regularly.
