We have developed a mouth guard which has revolutionized the shape and material of the conventional mouth piece. The H shape mouth guard has the unique shape like that of an H. Even with the new shape of the mouth piece it does not hinder the performance of the wearer. The following are the fundamental data collected by our group. In this study we examined its influences on leg power, the carry(the distance a golf ball is hit)and the motion of the club head during a tee off. The results are as follows : 1) By wearing or setting the mouth guard, the variation of leg power, measured with a Sybex II, showed an increase at selected angular verocity. The rate of increase averaged aproximately 15%. 2) The amount of work in anaerodush, an intensive, but short exercise, increased significantly by 1.25 seconds. 3) As for golf, all four of the test subjects joint performance increased their carries by 5.2 to 11.6 yards, using a 1 st wood. 4) Also the fluctuation of the head of the club decreased from 7.3 cm to 3.6 cm on average. Our group have found that the new H shaped mouth guard can absorb shock as well as not hinder the performance of the individual who is wearing it. Thus, the H shape mouth guard can be worn durinlg sports to enhance the participant's performance.
