本研究は,3軸加速度センサを剣道で使用する竹刀の先端部に取り付け,剣道の熟練者と初心者の素振りの違いを定量化し,初心者や技術の向上を目指す人のための練習支援システムを開発することを目的とする.現在,運動解析は主に,画像解析によって行われている.しかし,多数の高速度カメラを必要とし,専用の施設で計測する必要がある.また,データ処理に膨大な時間を必要とする.それに対して,本システムは,加速度センサを用いることにより,短時間で処理出来るため,実際の指導現場において有用な運動解析法であると考えられる.画像解析による結果を比較することにより,本研究は,振り降ろし方向の加速度が10%から90%に変化する時間(評価指標:T_2)と躍度(評価指標:Jerk)が,熟達度を評価出来る指標であることを示した.

For best performance in competitive sports, technique, stamina, spirit, and good conditioning are generally considered to be necessary. In Kendo a concert of "Shin-Gi-Tai (Mind-Technique-Body)" or "Shin-Ki-Ryoku (Mind-Spirit-Power)" is also an important element of a scoring hit. And as one becomes a more experienced player, he will notice the mind is the most crucial of all. When players do well in practice or matches, they most often say their "spirits" or "energies" are running high. These words sometimes mean concentration, perseverance, willpower, or fighting spirit. In this study a "Diagnostic Inventory of Psychological-Competitive Ability for Athletics 2 (DIPCA.2)" is conducted and analysis is made on the participants of the All Japan Kendo Federation Special Training Program and the members of the varsity Kendo teams of a "K" University and its affiliate high school. The results are as follows.1. In the comparison of the "five factors," national representatives returned high marks on "will to win," "mental concentration and stability," "confidence," and "strategic planning," while the ordinary participants of the training program scored high in "teamwork." However, no statistical significant difference was observed between these two groups.2. There was a significant difference in "confidence" in the "twelve degrees" between national representatives and ordinary participants.3. No significant difference was observed in "will to win" among all groups.4. Significant differences existed in "fighting spirit" and "perseverance" between college and high school students.
