The purpose of this study was to examine the psycho-physiological effects of respiratory control using vibration stimuli based on biological signals. We monitored changes in physiological indexes, the alpha attenuation coefficient (AAC), area S of the Lorenz plot (LP-area-S), heart rate (HR), and respiration as objective parameters, and Roken Arousal Scale (RAS) and Visual Analogue Scale (VAS) scores as subjective parameters in participants performing mental or physical load tasks. According to the results of the VAS scores and respiratory control rate, all participants felt fatigue and were able to breathe at a rate that was very close to the target rate in all periods. According to the results of the AAC and LP-area-S, changes in autonomic- and central nervous systems with respiratory control under mental or physical load were of the same tendency but varied in magnitude. In conclusion, the results of this experiment show that respiratory control can elicit physiological and psychological changes associated with relaxation. Moreover, the appropriate respiratory pattern will depend on the type of load.
