| 内容記述 | Clarifying stomatognathic function during continuous physical activity can contribute to the advancement of dental advice for athletes, including advice on maintaining the oral environment and improving performance. We elucidated stomatognathic function during physical activity, simultaneously analyzed occlusal force distribution and electromyograms (EMGs), and investigated occlusal contact and muscle activity during attacking movements such as continuous blows. Seven Nippon Kempo athletes of at least first-degree ranking, with normal dentition and jaws, performed attacking movements using both fists to strike a defender wearing a trunk protector. They continued until they subjectively experienced that they were approaching their limit. A custom sensor sheet was used to measure occlusal force distribution. Measured muscles included the masseter, suprahyoid, sternocleidomastoid and biceps brachii muscles. Before performing the test activity, subjects were instructed to perform maximum voluntary clenching for obtaining maximum (100%) occlusal force distribution and to engage all the measured muscles in a maximum voluntary movement for obtaining the EMG envelope integrated value/s; this established 100% muscle activity for each subject. The test activity measurement range was set from when the subject’s blow first hit the defender’s trunk until the subject’s final blow hit the defender’s trunk. This was divided into three equal stages: initial, middle, and final. The occlusal force distribution and relative muscle activity level were compared among the stages. The occlusal force distribution and the muscle activity level of masseter muscle increased over time. The muscle activity level of the sternocleidomastoid and suprahyoid muscles exhibited the same phases as those during maximum voluntary movement in the middle and final stages. During the continuous physical activity, increased occlusal force distribution and cervical and masseter muscle activity levels may suppress the swaying of the mandible and the head related to the trunk to maintain a stable posture for exercise. | |||||
