| Outline of Final Research Achievements |
The purpose of this study is to examine the effects of malodorous environment on autonomic nervous system and human behavior. First, participants were in different odor conditions in a sitting position. They were subjected to evaluations of subjective evaluation and changes of APG. Next, fatigue-inducing experiment with carrying burden was measured. Results of experiment showed that subjective evaluations of indoor air in malodorous conditions were lower than those in the non-smell condition. Furthermore, changes of LF/HF ratio in the isovaleric acid condition were higher than those in the other conditions. Also, in fatigue-inducing session with carrying burden, a change of LF/HF ratio in the isovaleric acid condition was higher than that in the non-smell condition. However, changes of the motion and myoelectricity of waist were similar under the two different odor conditions. The results showed that the influence of fatigue-inducing session is stronger in the malodorous condition.
