Purpose: The purpose of this study was to analyze the changes in the center of pressure (COP) by arousal regulation during static stability control task using various olfactory stimulating inhalant (ammonia, lavender and citrus). Methods: 11 healthy male adults (Mage = 28.55 years, SD = ±3.67) were recruited for the study. A biometric shirt was utilized to measure the heart rate while force plate (AMTI force-platform) was used to determine changes in COP area. The tasks were differentiated based on visual and ground proprioception (eyes open or close & presence of absence of memory foam). Results: The results of this study were as follows. First, for ammonia inhalant condition, average COP area lower than control condition. EO, EOC conditions had statistically significant lower value. Second, for lavender inhalant condition, average COP area higher than control condition. EC condition had statistically significant higher value. Third, for citrus inhalant condition, average COP area lower than control condition. EO, EC, and EOM conditions had statistically significant lower value. Lastly, there was significant differences in heart rate change in lavender inhalant, only. Conclusion: This study implies that the arousal regulation through olfactory inhalant affects the level of static stability. These results suggest that arousal regulation through olfactory inhalant may affect task performance and may contribute to improvement in performance of athletes.
