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.
