輕度認知損傷被視為失智症之前期階段,其在認知行為、神經電生理,及大腦結構等方面有負面之連結。近期研究指出,健身運動介入可能改善輕度認知損傷者在認知功能上的負面影響。為此,本回顧文獻集結健身運動介入與認知功能在輕度認知損傷者之相關研究,提供該研究議題之現況,及未來建議與方向。經文獻回顧獲致以下結論:(一)有氧健身運動介入部分,有效提升一般認知功能、及記憶相關執行功能。進一步則發現,有氧健身運動介入可增進生化指標與大腦活動等;(二)有別於其他認知類別,阻力健身運動介入對記憶有較佳效果。而太極拳介入,可改善一般認知功能與執行功能之表現;(三)多種健身運動、及健身運動結合認知訓練部分,可改善執行功能與大腦萎縮性之可能。雖然健身運動介入與輕度認知損傷呈現正向關聯,然該議題目前研究數量仍然不足,且在方法上仍有部分限制,後續仍須更多之研究投入。
Mild cognitive impairment (MCI) is recognized as the early stage of dementia. MCI is inversely connected to cognitive functions in terms of behavior, neuroelectrics, and brain structure. Recent research indicated that exercise intervention would decrease the negative impact of MCI. The present study was designed to integrate past research about exercise and older adults with mild cognitive impairment, and the contexts provided the current development of the targeted issue, certain methodological suggestions, and possibilities for future study directions. The conclusion of the review included: 1) In terms of exercise intervention, how exercise enhances the performance of general cognitive functions and the memory aspects of executive function. We further found that aerobic exercise intervention facilitates biochemical indicators and brain activation; 2) Unlike other aspects of cognitive function, resistance exercise intervention benefits memory performance. Moreover, the intervention of Tai Chi improves the performance of general cognitive functions and executive function; 3) Regarding multiple exercise intervention and exercise combined cognitive training, all of them improve executive function and inhibit brain atrophy. While there were positive relationships between exercise intervention and improvement of mild cognitive impairment, the article’s numbers of examples that examine this issue are not enough, and this remains a partial limitation in this study's method. So, we strongly suggested that the issue still needs more studies in order to focus more effectively on the particular research outcomes.
