本研究主要目的欲探討靜態補習時間對學童身體活動量與專注力的影響。以彰化縣線西國小三年級學生為研究對象，共計73位學童參與本研究。研究使用3D加速規，並且搭配問卷調查及專注力測試軟體。受試者必須配戴3D加速規記錄一週的身體活動量及接受專注力測試軟體的檢測，並得有效樣本45名。所得資料以描述性統計、獨立樣本t檢定、皮爾森積差相關及單因子變異數分析進行統計分析。本研究主要結果如下：一、身體活動量方面，男童高於女童，但性別未達顯著差異，平常日身體活動量低於週末的身體活動量，具有顯著的差異。二、不同的性別在專注力表現上有顯著的差異，女生專注力的表現比男生好。三、專注力的表現與課業成就表現達顯著相關。四、補習時間對身體活動量與專注力之間無明顯的相關。雖然本研究結果靜態補習時間對身體活動量與專注力無明顯的相關，但學童補習的比率高達82%，且身體活動量嚴重不足，建議家長與教育單位應多安排各種休閒活動並鼓勵學童參與戶外運動，改善身體活動不足的問題，進而增進身體健康，並養成規律運動習慣。

　　The purpose of this study is to investigate the influence of after school learning activities toward children’s Physical activities and attention. Seventy elementary school students, who study in the third grade, join my study. The study uses 3D accelerometer, along with questionnaire and attention test software. In the beginning, all of the participants have to wear 3D accelerometer for a week and record their physical activities and attention test, and after the test, forty-five effective participants are chosen. The data are statistically analyzed by descriptive statistics, t-test, Pearson’s correlation and ANOVA. The results of the study are as following:
1.In physical activities, boys are higher than girls, but there is no significant difference. However, there is a significant difference between weekdays and weekend.
2.In attention, there is a significant difference between sexes. Girls are better than boys.
3.There is a significant difference between attention and study achievement.
4.There is no significant correlation of after school learning activities to physical activities and attention.
Although this study shows that there is no significant correlation of after school learning activities to physical activities and attention, the ratio of after school learning activities for children are still up to eighty-two percent. Obviously, children in Taiwan are seriously lack of physical activities, and we suggest parents and schools should arrange all kinds of recreation activities for children and encourage them to attend outdoor activities in order to improve their problem in the lack of physical activities. In this way, children can live a healthier life and keep regular habits to do exercise.
