Description

We conducted radio exercises –warm-up calisthenics performed to music and guidance from radio broadcasts–with （the aroma + exercises group） and without （the exercises-only group） the addition of peppermint essential oil with awakening effect to 15 subjects. All subjects experienced both group and we carried out a subjective evaluation and an evaluation of autonomic nervous activity both before and after the radio exercises. The peppermint scent was added by inhalation using a diffuser. Regarding autonomic nervous activity, we compared measurements within each group as well as between each group. In the subjective index, we also did comparisons within each group as well as between each group, both before and after implementation. The results showed that parasympathetic activity rose significantly at 120 seconds after exercise in the exercises-only group compared to 60 seconds after exercise in the aroma + exercises group. Moreover, at 120 seconds after implementation, the aroma + exercises group had significantly higher parasympathetic activity than the exercises-only group. In the subjective index, the energy arousal of the aroma + exercises group decreased significantly after exercise compared to before exercise, and was significantly lower than the exercises-only group. From all these results, it was clear that peppermint oil raises parasympathetic activity significantly during radio exercises and makes people subjectively more relaxed afterward.
