摘要註:	過去有許多研究指出運動後之α腦波活動明顯比運動前增加，並推論運動後腦波反映出放鬆或焦慮降低之現象。這些研究內容包含針對單次運動前及運動後腦波的差異，以及長期運動計畫介入對腦波的影響。但是在運動過程的設計中，極少有針對一般健康成年人在正常運動習慣的模式下，測量腦波變化。並且由於腦波儀使用的限制，亦鮮少有研究進行運動中腦波變化的探討。因此本研究即針對一般健康成人，設計包含暖身運動、持續運動以及緩和運動在內的「完整運動流程」，並利用無線傳輸之腦波儀，觀察受試者於此流程中完整的運動前、運動期間以及運動後之所有腦波變化。本研究受試者為志願參與研究之本校健康大學生（n=26, 21.8±2.6 years），受試者先配戴無線腦波儀及無線心律偵測帶，再經過前測及暖身運動後，於跑步機上以心跳速率為判斷依據下進行逐漸加速至中強度 (moderate intensity) 的快走運動，並持續20分鐘的中強度快走運動；接著進行減速、緩和運動及後測。在整段腦波資料中，擷取前測、加速前期、加速後期、中強度運動前期、中強度運動中期、中強度運動後期，以及減速前期、減速後期和後測等，共九個時段的腦波，分析比較α波強度變化與α波變化比率。結果顯示：（一）自加速期開始，α波強度即顯著的上升，並於加速後期達到高峰；（二）持續運動期間的α波強度不再持續上升，呈現相對平穩的狀態；（三）進入減速期之後，α波強度呈現顯著下降趨勢；（四）後測期α波強度比加速後期及運動後期顯著較低，但後測期α波強度顯著高於前測期。因此經由腦額葉α波的變化推論，中強度運動的完整運動流程中，在還未達到所要求的強度前，即可使大腦產生明顯之放鬆狀態；而持續較長時間的中強度運動有助於此放鬆狀態之維持。 Many studies have indicated that the electrocortical activity in alpha frequency band was increased after exercise. Due to the limitations of equipment, most studies were focused on electrocortical activity changes before and after exercise, rare studies looked into EEG (electroencephalography) changes throughout a complete exercise procedure which includes warm-up, continuous exercise and cool-down stages. The present study aimed to investigate the changes of EEG power of a complete exercise procedure. This procedure includes the following stages: 5-10 minutes of warm-up, 40 minutes of heart-rate based moderate intensity brisk walking on treadmill, and 5-10 minutes of cool-down. All participants (n=26, 21.8±2.6 years) were equipped with the telemetric EEG set and heart rate sensor, and then performed the exercise procedure in gymnasium. Nine EEG fragments were obtained from the procedure: pre-test; early and late speed-up; early, middle, and late moderate intensity exercise; early and late speed-down; and post-test. Results showed that (1) α power increased significantly and reached a maximal level during late speed-up stage; (2) α power maintained at a stable level during moderate intensity exercise stage; (3) α power decreased significantly during speed-down stage; (4) α power of the post-test stage was lower than late speed-up and late exercise stages, but higher than the pre-test stage significantly. The results suggested that the increasing of α activity, which reflects cortical relaxation, can be achieved by exercise, even before reaching the required exercise intensity, and extension of moderate intensity exercise is helpful in maintaining the cortical relaxed condition.
