本研究主要比較單方精油與複方精油對運動後心率變異及壓力之影響，以跑步機為運動介入，促使交感神經活化導致心跳加速、呼吸速率增加，後休息15分鐘時給予單方精油(檀香)或複方精油(檀香與薰衣草)，再檢測心率變異分析儀及腦波監測儀，以探討一旦運動停止後交感神經活性迅速被抑制，副交感神經活性增加，其單方精油與複方精油對心率恢復過程及腦波調控機制之影響。以台灣南部某專科學校為收案地點，採隨機取樣方式並排除有氣喘發作史及心臟疾病史之學生，共收案10名。將前測未介入精油與後測介入單方精油或複方精油精油後之的心率變異生理參數:平均心跳(Mean Heartbeat，Mean HRT)、壓力指數(Pressure Index，PSI)、總能量(Total Power，TP)、極低頻功率(Very Low Frequency，VLF)、低頻(Low Frequency， LF)、高頻功率（High Frequency，HF）、低頻/高頻功率比(LF/HF ratio) ，並搭配腦波指數(疲勞指數、專注度、放鬆度、壓力)資料進行檢定，結果顯示受試者使用單方精油(檀香)其心率變異生理參數HRT、LF、LF/HF及腦波監測儀數據中的專注度、壓力、疲勞指數皆為下降，但不具顯著性；顯示單方精油(檀香)在活化副交感神經活性上效果不明顯。使用複方精油(檀香與薰衣草) 其心率變異生理參數VLF、LF皆為下降，但不具顯著性；而腦波監測儀數據顯示，壓力指數下降及放鬆指數上升，均達統計差異(p<0.05)；顯示使用複方精油(檀香與薰衣草)具有提升副交感神經活性，特別是在壓力放鬆的成效上。 This research aims to investigate the effect on heart rate variability and pressure before and after applying pure or compound essential oil after exercising. After exercising on the treadmills to activate sympathetic nerve， heartbeats accelerate and the rate of respiration increases. After taking a 15-minute break， pure essential oil (sandalwood) or compound essential oil (sandalwood and lavender) is applied. Then pressure is analyzed via an electroencephalogram and cardiac rhythm is analyzed via a heart rate variability analyzer. Once stopping exercising， activity of sympathetic nerve stops quickly and parasympathetic nervous activity has increased. With applying pure and compound essential oil， the effect of the process of heart-rate recovery and modulation of brain wave regulation are discussed. This research is conducted in one junior college in southern Taiwan. 10 students are randomly chosen， exclusive of those who have asthma and history of heart disease. The data of physiological parameters of heart rate variability (HRT， PSI， TP， VLF， LF， HF， LF/HF) in the pre-test where essential oil is not applied and the pro-test where either pure or compound essential oil is applied， along with brain wave index (fatigue index， concentration， relaxation， pressure) being detected. The result shows that after applying pure essential oil (sandalwood)， students’ physiological parameters of heart rate variability (HRT， LF， LF/HF) and the index of concentration， pressure and fatigue received via the electroencephalogram have decreased but not obviously. It shows the effect of pure essential oil (sandalwood) on activating parasympathetic nerve is not obvious. However， physiological parameters of heart rate variability VLF， LF had decreased but not obviously after applying compound essential oil (sandalwood and lavender). The data collected via electroencephalogram show the pressure index decreases while relaxation index increases， with statistical significance (p<0.05). Applying compound essential oil (sandalwood and lavender) increases parasympathetic nervous activity， particularly for effect of relaxation on pressure.
