本研究之目的在探討急性健身運動對計畫相關之執行功能在立即後與延續時間上之影響。本研究招募30位年齡介於20至30歲的實驗參與者，並隨機分派為健身運動組或控制組。健身運動組進行30分鐘60%儲備心跳率的腳踏車運動介入，而控制組則以閱讀相同時間作為介入。認知測驗採用量測計畫能力的倫敦塔測驗，並分別於介入前、介入立即後、後30分鐘、後60分鐘等時間點做量測。研究結果發現：健身運動組在立即後時間點之移動次數表現顯著少於控制組；此外健身運動組在後30分鐘、後60分鐘時間點之起初時間亦長於控制組。本研究之結論指出，急性健身運動對不同量測時間點的執行功能效益是有其選擇性：以立即後的時間點而言，對於移動次數所代表的計畫能力有其敏感性；而以延續時間點而言，對於起初時間所代表的抑制能力有其正面效益；然而，急性健身運動對於工作記憶力與計畫效率改善的影響則較有限。

The purpose of this study was to examine the immediate and sustained effects of an acute bout of exercise on planning of executive function among adults. Thirty participants aged from 20 to 30 years were recruited and randomly assigned into either exercise or control group. The exercise group performed ergometer exercise at 60% heart rate reserve (HHR) for 30 mins, while control group involved in reading of the context related to exercise training. The cognitive measurement was assessed by Tower of London Task, one of the main neuropsychological assessments for measuring planning at before, immediately after, sustain 30 mins after and sustain 60 mins after each treatment. The results indicated that there was a significant positive effect on the total move score at immediately after in exercise group. In addition, initial time in exercise group showed longer duration than those in control group at sustain 30 mins and sustain 60 mins conditions. The present study concluded that acute exercise had a selective beneficial effect: Acute exercise was sensitive on planning ability in terms of immediate timing; while exercise also benefited inhibitions in terms of sustained timing. However, acute exercise had limited influence on adults' working memory and planning efficiency.
