ABSTRACT
<b>Objective</b>: The psychophysiological and immunological effects of exposure to different varieties of essential oils on fatigue were extensively investigated in students performing personal computer tasks.<br> <b>Design</b>: Randomized crossover study<br> <b>Methods</b>: This study was approved by the Kyoto Prefectural University of Medicine Research Ethics Committee, and informed consents were obtained from all subjects. Eight healthy male university students with mean age of 22.38±1.30 (range 21–24) who served as the subjects in this study were given a 120-minute personal computer task with 10-minute rest period before and after the task.<br> During the course of performing PC task, subjects were either exposed to one of the five essential oil odors (grapefruit, peppermint, true lavender, blend A, blend B) or not exposed to any odor at all, serving as the control in the study. Each of the six odor setting were carried out on separate days upon which psychophysiological and immunological parameters of fatigue in the subjects were evaluated.<br> <b>Results and Conclusions</b>: The results of this study suggest that exposure to essential oil odors affects the autonomic nervous and immunological system when engaged in a personal computer task. Moreover, different varieties of essential oils cause different vital reactions. In particular, peppermint essential oil exhibits fatigue-reducing effects.<br>
ABSTRACT
<b>Objective</b>: On the psychological, physiological and immunological parameters, the effects of green tea drink were comprehensively investigated.<br> <b>Design</b>: This study used a randomized cross-over design.<br> <b>Methods</b>: After a 120-minute computer fatigue task, participants were randomized into two groups: one tasked to drink green tea and the other water. Blood collection, measurement of the P300 event related potential and questionnaire were executed three times: before and after the computer fatigue task and then, 30 minute after drinking green tea or water. These data were then compared. High Frequency (HF) and average Low Frequency/High Frequency Ratio (LF/HF) were calculated.<br> <b>Result</b>: In a state of fatigue, drinking green tea showed dominance of the parasympathetic nervous system, an improvement in their attentiveness, and elevation of NK activity; thereby, reducing fatigue, particularly, mental fatigue.<br> <b>Conclusion</b>: This study comprehensively showed the fatigue-reducing eggect of green tea in psychological, physiological and immunological parameters. It is hereby, suggested that green tea is indeed, helpful in reducing fatigue.<br>
ABSTRACT
Recently, the number of athletes who receive acupuncture therapy is increasing. However, most of these athletes receive acupuncture therapy with single-acupuncture and/or electro-acupuncture to a local point, or a trigger point. We experienced two water polo athletes who were improved using acupuncture and moxibustion therapy with “zuisho” therapy. Case 1 was 16 year old man. He became aware of pain in his right thumb after training, which continued with extended training time, a numbness in his left hand appeared more, and he received acupuncture and moxibustion therapy. These symptoms disappeared immediately with acupuncture and moxibustion therapy using the standard traditional methods, such as contact needling to a yuan point, and in situ acupuncture to a back shu point, etc. Case 2 was 17 year old man. He received acupuncture and moxibustion therapy for lumbago and stiffness of the neck. These symptoms disappeared immediately after acupuncture and moxibustion therapy using the standard traditional methods such as contact needling to a yuan point, and inserting needles into a back shu point, an extra meridian, etc. In these two cases, symptoms were improved with “zuisho” therapy, and both could continue with longer and more strenuous training. This suggests that acupuncture and moxibustion therapy using the standard traditional methods are useful for athletes.
