靜態行為對健康產生負面影響之論點已成為當今重要的公共衛生議題,目前以短時間多回合身體活動中斷靜態行為之研究已顯示能改善諸多與認知功能有關之生理指標。然而,直接對認知功能影響之文獻尚未有一致結論,本文目的為透過系統性回顧探討採用短時間多回合身體活動中斷靜態行為對認知功能之影響。經系統性回顧後最後共納入6篇文獻,其中有2篇文獻顯示短時間多回合中斷靜態行為可以改善認知功能,其包括:抑制控制、認知彈性、工作記憶以及注意力。本文推論提高身體活動強度、延長身體活動時間、以及降低靜態行為時間可能是短時間多回合身體活動中斷靜態行為對於認知功能之關鍵因素,目前該議題仍處於初始階段,且靜態行為目前亦為多數族群習慣之生活行態,未來研究應持續針對此議題進行探討。建議未來必須持續釐清身體活動、靜態行為與認知功能三者間的關係,亦可搭配不同生理指標以釐清身體活動中斷靜態行為與認知功能之可能機轉。
Sedentary behavior, which brings lots of negative health outcomes, has been considered as an important health public issue. Accumulating research has shown breaking sedentary behavior with short bouts physical activity positively impact many physiological indicators related to cognitive function, however, the effect on cognitive function was still uncertain. The aim of this systematic review was to determine whether the literature supports that breaking sedentary behavior with short bouts physical activity improves cognitive function in healthy adults. After following review and quality assessment, 6 articles were identified to fulfill the inclusion criteria. Two articles showed breaking sedentary behavior with short bouts physical activity could improve cognitive function, including inhibitory control, cognitive flexibility, working memory and attention. In this systematic review, it is found that increasing the intensity and time of physical activity and reducing the time of sedentary behavior may be the key factor for cognitive function of breaking sedentary behavior with short bouts physical activity. In conclusion, this issue is still at a preliminary stage and should be discussed further. The future research is suggested to clarify the possible mechanisms between breaking sedentary behavior and cognitive function, by using different intensity, type, and time, of physical activity, sedentary behavior patterns, and physiological indicators.
