In this study, we examined how gum chewing, which comprises masticatory movement obtained as an acquired function, affects sports performance by comparing physical movement response times between subjects playing sports with gum chewing and those not engaged in gum chewing. The subjects comprised 5 male adults with healthy teeth and jaws who were right handed (average age: 27.2 years old) and had no subjective or objective abnormalities in the mandibular joints or masticatory muscles, etc., and had received sufficient explanations regarding the purpose of this experiment and had agreed to participate therein. As for test muscles, we selected the right and left masseter muscles, the medial great muscle of the quadriceps femoris muscle, the gastrocnemius muscle, and the long fibular muscle, for a total of five muscles. Moreover, all of the muscles other than the left masseteric muscle were the muscles of the right leg. We measured the reaction time of the long fibular muscle and the physical movement response time. These items were compared with two variables: non-gum chewing and gum chewing. The result that there were no significant differences in either set of means, but the time tended to be shorter with gum chewing. The results of this experiment indicate that gum chewing shortens the body response time, provides the same mental effects as those previously reported, and may also provide a significantly positive effect on performance in sports.
