    Effects of Acute Exercise and Age on Inhibitory Control: A Combined ERP and Source Localization Study
    (2018) 謝漱石; Hsieh, Shu-Shih
    本研究之目的為二： (一) 檢驗年齡是否影響急性運動對抑制控制的行為與電生理表現之效益；及 (二) 了解運動促進抑制控制表現的神經基質，並檢驗年齡是否影響該神經基質。本研究招募24位年輕男性 (平均年齡 = 24.0 ± 3.1 年) 及20位老年男性 (平均年齡 = 70.0 ± 3.3 年)。參與者以對抗平衡次序方式從事一次急性運動情境 (強度為 50-70%的心跳保留值) 與一次影片情境，其後使用Stroop叫色測驗進行抑制控制表現測量，同時進行認知行為與事件關聯電位的資料收集。行為表現的參數包含反應時間、反應正確率；事件關聯電位的參數則包含P3與N450成分波，另以sLORETA作為腦波源分析之工具。本研究結果顯示，急性運動能縮短參與者的反應時間，其效益不受認知作業的難度或參與者年齡所影響；作業難度對於反應時間產生的干擾於運動後有所減少，其效益不受年齡所影響。事件關聯電位部分，急性運動誘發較大的P3振幅並降低N450的振幅，其效益不受作業難度或年齡所影響。源分析部分，急性運動誘發年輕人大腦左側外側前額葉及前扣帶迴的活化；老年人則是於運動後於右半腦外側前額葉產生活化，伴隨前扣帶迴活化的降低。根據上述結果，本研究建議年輕人與老年人於急性運動後可能獲得相似的提升效益，惟其潛在的神經基質則因年齡有所不同。

    Abstract Background The objective of the current study was to examine whether the relation between aerobic fitness and academic achievement during adolescence is subject-dependent, and to investigate cumulative and recency effects. Methods This study made use of two nationwide datasets. The first was the aerobic fitness profile of junior high school students collected by the Ministry of Education in Taiwan. The second contained the scores on the Basic Competence Test for Junior High School Students (BCTJH). The sample consisted of 382,259 students who completed the BCTJH in the 5 years between 2009 and 2013. Data on each student’s aerobic fitness during their three years of junior high school were matched with their exam results at the end of this period. Results The results revealed that students classified as highly-fit during at least one of the three years had higher BCTJH scores than those who never achieved this level, with the size of effect increasing with the length of time that fitness was maintained. Additionally, aerobic fitness in the final year was more closely linked to BCTJH scores than that in the earlier two years. Fitness was also more strongly associated with exam performance in math, science and social science, relative to language-related subjects. Conclusions Our findings suggest that while aerobic fitness is positively related to academic achievement in Taiwanese junior high school students, the relationship depends on academic subject, as well as the length and time of being aerobically fit.
