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.
