Synchronization between Respiration and Mastication Functional Coordination of Respiratory and Digestive Systems

Abstract—The purpose of our study is to evaluate the relationship between respiratory period and chewing period. In 10 healthy peoples (6 males and 4 females, age 26 ± 7 years), EMG of masticatory muscles and respiratory curve during chewing of gum were measured and synchronicity between respiration and chewing were analyzed using the phase of chewing occurring within respiratory period. Results, the coherence between the two signals at the peak frequency of respiration was 0.06 ± 0.03 (mean ± SD). In all subjects, the relationship between respiration period and chewing period was random and was not correlated. In this experiment, chewing period wasn’t controlled. Therefore, it is considered that respiration may have been synchronized if the period of chewing was controlled.

Index Terms—Chewing, respiration, EMG, synchronization.
