肥胖對於大腦健康相關之執行功能存在負面影響,過去研究已發現,急性健身運動對於執行功能存在正面效果,且該效益可延伸至肥胖族群。因此,本文目的為回顧急性健身運動對肥胖族群執行功能之影響,並針對肥胖與執行功能和急性健身運動對於肥胖族群執行功能之影響進行回顧。透過肥胖、急性健身運動與執行功能等關鍵字於PubMed或Google學術等網站搜尋相關文獻。結果發現,肥胖對執行功能之抑制功能、工作記憶,以及認知彈性皆有負面影響,而急性健身運動提升肥胖族群執行功能之效益已在少數研究中發現。雖目前聚焦於肥胖族群之研究為少數,但值得注意的是,該些研究涵蓋多種運動型態,且對於執行功能之三種次成分皆有正面影響。整體而言,急性健身運動能改善肥胖族群之執行功能,並可在不同運動型態及執行功能成分上發現其效益。然而,該研究仍屬初步階段,未來仍須針對該議題加以探討。
Obesity is negatively associated with executive functions. Previous studies have observed that acute exercise is positively linked to executive functions, and that the beneficial effects of exercise could extend from healthy to obese populations. The purpose of the present study was to review the effects of acute exercise on executive functions in an obese population, an investigation which focused on two parts: (a) the relationship between obesity and executive functions; (b) the effects of acute exercise on executive functions in relation to obese subjects. Our search database included PubMed or Google Scholar, and proceeded through entering keywords such as obesity, acute exercise, and executive function. The results observed that obesity has a negative effect on the study subjects' inhibition, working memory, and cognitive flexibility. Acute exercise could improve executive functions obese population in a few studies, which included a variety of exercise models, and also investigated the three subcomponents of executive function. These findings suggest that acute exercise improve the executive functions of obese people, and the beneficial effects could be observed by different exercise modalities; however, the research is still in its preliminary stages, and thus the topic requires further discussion, based on the findings of future investigations.
