摘要

過去研究發現運動可以促進身體上的健康狀況，對心理層面也有著正面的效益。如何預防藥物濫用者在戒除後的復發亦是重要的議題。本研究採用停止訊號作業來評估藥物濫用者的抑制控制與錯誤監控能力，分別以停止訊號反應時間和錯誤後減慢作為抑制控制能力和錯誤監控的行為指標。進一步加入急性有氧運動介入，探討在運動及閱讀後，對抑制控制與錯誤監控能力之影響。本研究招募對象為17名藥物濫用者及17名一般健康者，實驗情境為30分鐘的運動介入及30分鐘的書籍閱讀作為控制情境，實驗採用對抗平衡設計，一半的參與者先進行運動再閱讀，另一半的參與者則是相反。研究結果發現運動介入後會使二組受試者的停止訊號反應時間縮短，閱讀無此效果。在錯誤後減慢上，無論運動介入與否，藥物濫用組的運動後減慢顯著低於一般控制組。從本研究結果發現急性有氧運動處遇介入可以短暫改善抑制控制能力，但其影響程度及持續性，還需要進一步探討如何能產生長期的效應，以幫助預防藥物濫用行為的復發。

Past research has found that exercise can promote physical health and also have positive benefits at the psychological level. How to prevent drug abusers from relapsing after withdrawal is also an important issue. In this study, the stop signal task was used to evaluate drug abuser's ability to suppress behavior and to evaluate error monitoring. Stop signal response time and post error slowing were used as behavioral indicators of inhibitory control ability and error monitoring respectively. Further, an acute aerobic exercise intervention was used to investigate the effects of this on both measures. The study enrolled 17 drug abusers and 17 general healthy subjects. The experiment employed 30 minutes of exercise intervention and 30 minutes of book reading as a control condition on different days with a counterbalanced design for the order of interventions. After the exercise intervention, the stop signal response time of the two groups of subjects was shortened but reading had no effect. There was less post error slowing in the drug abusers than controls but this measure was not affected for either group by either intervention. This study found that acute aerobic exercise can improve the ability to control behavior, but does not affect the error monitoring process. Since the recurrence of drug abuse is related to inhibitory control, the results show that an acute aerobic exercise intervention may confer a useful improvement in inhibitory control in the short term. Future work aiming to produce a persistent change based on exercise interventions would clearly be beneficial and may help in the prevention of the recurrence of drug abuse behavior.
