補習時間對國小學童課後身體活動量的影響

本研究主要目的欲探討補習時間對國小學童課後身體活動量的影響。本研究以30多位國小學生為受試者，分為一週補習時數超過10小時以及一週補習時數低於3小時兩組，每組各15位學童。研究使用客觀的科學儀器-3D加速規，並且搭配問卷調查及運動自我效能量表檢測學童身體活動量。受試者必須配戴3D加速規及記錄身體活動五天，再以統計方法分析所測得之數據與一週補習時間的關係。研究結果發現：學童一週的總補習時數與其課後動態身體活動量相關，一週總補習時數高於10小時的學童其課後動態身體活動時間、運動頻率和能量消耗皆顯著低於一週總補習時數3小時的學童。

To elucidate whether the participation of cramming school after formal school time affect the physical activity in elementary school children, thirty elementary school students were randomly recruited and divided into two groups. The fifteen subjects with the cramming school time more than ten hours a week were as cramming school group (CS group) and the other group that of less than three hours a week as normal school group (NS group). The 3D accelerometers, self-report questionnaires and youth exercise self-efficacy scale (YESES) were used to estimate the physical activities during experiment period over 5 days. The level of physical activities after school time exhibited negative relationship to the participating duration of cramming school after formal school time. The level of physical activities, exercise frequency and energy expenditure were significantly greater in CS group than in NS group. In summary, the participating duration of cramming school after formal school time over ten hours caused immobilization in elementary school children.
