情緒對人的生活，可以說是息息相關的一環。有人這樣說過，做事前要先處理好情緒，情緒不好可能會影響我們生活表現或者工作表現。而現代人的繁忙生活所帶來的壓力，不管是來自工作或家庭亦甚至是感情問題，都可能導致我們產生的焦慮、憂鬱、悲傷等等的負面情緒。根據壓力減少理論，自然環境可以達到減少壓力的效果，而運動也是可以減少這些負面情緒的一種方法，況且比起其他娛樂，運動是一種可以不用花費任何費用且可隨時隨地實行的方法。結合自然與運動兩者的綠色運動也可以有效對情緒帶來效益，然而是自然帶來的效益還是運動帶來的效益較多，目前尚未有明確的知道有多少綠色的程度可以改善情緒。本研究目的為比較三種不同綠色覆蓋率的環境中騎乘自行車，來探討其壓力減少的效果。方法：運用眼球追蹤技術與問卷調查的方式進行，共將招募60位研究參與者，將實驗環境分成控制組、高綠色覆蓋率組（綠色覆蓋率60~70%）、低綠色覆蓋率組（綠色覆蓋率約40~50%）。研究參與者將在這三種環境中騎乘自行車，藉由情緒問卷量測研究參與者的情緒狀態，及收集實驗過程中的眼動數據。將數據整理分析後做統計，統計分析使用重複量數變異數分析，顯著水準訂為p<0.5。結果：本研究發現：盤斯量表的部分為，高綠色覆蓋率組[p= .001]與低綠色覆蓋率組[p= .001]皆有較好的情緒改善，但是控制組[p= .147]沒有顯著差異;眼動數據的部分，三組都有情緒的改善。結論：有綠色運動的介入下情緒改善都是有幫助的。在心理層面，綠色多寡可能會影響到情緒的改善，但是在生理數據方面可能綠色多寡沒有太多改善上的差異。

Mood may affect our performance not only in our life but also in our works. Emotion can be said to be a closely related part of our life. The stress may lead to negative emotions such as anxiety, depression, sadness. A number of studies have suggested that the natural environment can achieve the effect of reducing stress. And a lot of studies have also pointed out that exercise is also a way to reduce these negative emotions. Combining nature and exercise can also effectively bring benefits to the emotions. Nevertheless, the benefits brought by nature or the benefits brought by exercise are more. And there is no clear understanding of how much greenness can improve mood. This study used one 15-min bout of physical activity to compare the effects of pressure reduction in three different green coverage environments. Sixty participants were recruited and divided into three groups [i.e., control (n=20), high green coverage (n=20), and low green coverage (n=20) groups] . The data on emotions were measured by POMS and eye tracking. This study found that in terms of the questionnaire, the high green coverage group and the low green coverage group had better emotional improvement than the control group. As for eye movement data, these three groups all had better emotional improvement. This study found that emotional improvement under the intervention of green exercise is helpful. Furthermore, the amount of green may affect the improvement of mood.
