[Purpose] The purpose of this study is to examine the effect of aroma stimulation during isotonic exercise on the rating of perceived exertion (RPE) and the blood fatigue factors of athletes who have patellofemoral pain syndrome (PFPS). [Subjects and Methods] The research subjects were seven athletes in their twenties who suffer from PFPS. They were divided into a control group and an aroma stimulation group and performed isotonic exercises repeatedly. After exercising, the RPE and blood fatigue factors, including creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and ammonia, were measured through blood sampling. [Results] The aroma stimulus group showed significantly lower RPE than the control group immediately after exercising, which included leg presses, leg curls, bicep curls, and leg extensions. Among the blood fatigue factors, the change in LDH indicated the effect of aroma stimulation. [Conclusion] We confirmed that aroma stimulation during isotonic exercise has the positive effect of reducing the RPE and blood fatigue factors, such as blood LDH, of the athletes with PFPS.
[目的] 本研究旨在探讨等张运动期间香气刺激对患有髌股疼痛综合征（PFPS）的运动员的主观用力程度（RPE）和血液疲劳因子的影响。[对象与方法] 研究对象为7名二十多岁患有PFPS的运动员。他们被分为对照组和香气刺激组，并反复进行等张运动。运动后，通过采血测量RPE和血液疲劳因子，包括肌酸磷酸激酶（CPK）、乳酸脱氢酶（LDH）和氨。[结果] 香气刺激组在进行腿部推举、腿部弯举、二头肌弯举和腿部伸展等运动后，立即显示出比对照组显著更低的RPE。在血液疲劳因子中，LDH的变化表明了香气刺激的效果。[结论] 我们证实，等张运动期间的香气刺激对患有PFPS的运动员具有降低RPE和血液疲劳因子（如血液LDH）的积极作用。
