| Outline of Final Research Achievements |
The activation pattern of masticatory muscle during motor activity was unclear. From the present study, it was observed that masseter muscle activity appeared in association with shot in ice hockey. In addition, six of 7 volunteers expressed electromyographic (EMG) activity of masseter muscle related to arm movement under conditions with 5.0 and 10 kg dumbbell. The onset of the masseter EMG activity relative to the onset of the deltoid EMG under condition with 10.0 kg dumbbell was significantly faster than that with 5.0 kg dumbbell in the 6 volunteers. The magnitude of the masseter EMG activity under condition with 10.0 kg dumbbell was significantly larger than that with 5.0 kg dumbbell in the 6 volunteers. Moreover, our results showed that masseter muscle activity had relationship with the center of pressure during voluntary arm movement. Accordingly, it was suggested that the activation of masseter muscle related to motor performance would play an important role in motor control.
