The purpose of this study was to investigate the relationship between masticatory muscles function and exercise of the whole body in sports. Six players in the soccer team"Sanfrecce Hiroshima"volunteered as subjects for this project. Three kinds of kicking (the most powerful shoot, the longest pass, slight shoot) were selected as the test exercise of the whole body. Electromyographic signals during kicking were recorded in subjects from both sides of M. Temporalis Anterior and M. Masseter, from M. Gastrocnemius and both sides of M. Quadriceps Femoris by means of surface electrodes and telemetry EMG device units. Furthermore, kicking forms were recorded by use of the video camera. Following results were obtained; 1. Clear activity of four masticatory muscles during kicking was shown in two subjects. 2. There was a positive correlation between masticatory muscles activity during kicking (the duration and the ratio to maximum-clenching muscles activity) and the strength and form of kickings. Those results suggest that the masticatory muscles might play a role in kicking and the exercise of the whole body in sports.
