急性有氧健身運動對計畫相關執行功能之影響

Effect of acute aerobic exercise on planning-related executive function

目的：探討急性有氧健身運動對計畫相關型態執行功能之影響。方法：本研究招募21位大學年齡的健康參與者，並隨機分派至健身運動組或控制組。健身運動組以單次30分鐘70％儲備心跳率的腳踏車健身運動作為介入方式；控制組則以閱讀相同時間作為介入。認知表現採用量測計畫型態執行功能的倫敦塔測驗，並於介入前與立即後進行量測。結果：健身運動組在總移動次數、總執行時間，以及總問題解決時間等指標之表現較控制組佳；然在總移動正確數、總起初時間、總犯規次數、總超時次數等指標則無顯著差異。結論：本研究發現，急性有氧健身運動對於倫敦塔測驗所誘發出之計畫相關執行功能，有其效益的差別性。建立在本研究的初步發現，未來研究建議可由其他年齡族群、健身運動中或延續效應、性別、樣本數、以及其他健身運動強度等方面作後續探究。Purpose: To explore the effects of acute exercise on planning-related executive functions. Methods: This study recruited twenty-one healthy college students who were then randomly assigned into either exercise or control groups. The exercise group participated in an ergometer exercise with a 70% heart rate reserve for 30 minutes, while the control group engaged in reading for the same time period. The groups' cognitive performances were assessed by the Tower of London Task, one of the main neuropsychological assessments measuring planning, both before, and immediately after the intervention. Results: Total number of moves, total execution time, and total problem-solving time in the exercise group were significantly fewer than those in the control group. However, significant differences were not found in total correct scores, total initial times, total rule violations, and total time violations. Conclusions: The present study indicated that acute exercise had selective beneficial effects on planning- related executive functions. Based upon the initial evidences of the present study, future research is suggested to examine issues regarding populating with different age, during or delay effect of exercise, gender, sample size, and exercise intensity.
