バットスイングにおける運動連鎖を支援する音声リズムBFデバイスの開発

（上半身に着目したデバイス有効性の検証）

In 2011, baseball was designated as a required subject at the elementary and junior high school in Japan. Thus, as teachers, teaching baseball skill would be important to instruct required baseball skill for students. Batting is one of the most difficult skill and kinetic chain is very important to achieve ideal batting form. In the present study, we developed auditory cue based biofeedback device that could induce desirable batting form (i.e., ideal kinetic chain). The device gives the player auditory cue that related to their body motion. Pre-posttest found that beginners trained with the device increased the swing speed than that trained with the no device.
