This study examined the psychological structure of "images of Kendo" in Kendo club students and general students. This study included 513 subjects (138 male, 375 female, average age 19.6±1.22 years old), who were asked to write the 10 sentences that came to mind after the phrase "Kendo is" on a questionnaire. Of those sentences, they were asked to choose the one sentence evoking the strongest image of Kendo. Text mining of selected sentences extracted words, and the relations between them were analyzed.The analysis showed that Kendo club students and general students had different images of Kendo. Many Kendo club students responded with psychological aspects, such as "disciplining the human character" and "training the mind." General students gave many answers regarding its physiological aspects such as "sweat" and "voice," reflecting Kendo as a sport. However, both Kendo club students and general students cited Reigi (etiquette) in their images of Kendo.

The purpose of this study is to examine the psychological structure of "images of KENDO" in university Kendo club students. This study included 235 subjects (89 male, 146 female), who were asked to write the 10 sentences that came to mind after the phrase "Kendo is" on a questionnaire. Of those sentences, they were asked to choose the one sentence evoking the strongest image of Kendo. Text mining of selected sentences extracted words, and the relations between them were analyzed. Both male students and female students cited "disciplining the human character" and "training the mind" in their images of KENDO.

The ABO blood type is naturally accepted in Japan and is often used for entertainment, such as offering blood type personality diagnoses and blood type divination. Even today, the belief that blood type and personality have an impact on sports performance persists, especially on the Internet. There are conflicting opinions about the authenticity of this idea, and they have not seen the conclusion. In order to offer further insight, this study describes the relationship between sport performance and blood type using quantitative surveys and literature materials.We conducted a web questionnaire survey for 306 university students majoring in three martial arts: kendo, judo, and sumo. The questions asked participants about their athletic career, competition results, qualifications, and blood type. The response rate was 98.6%. Regardless of the specific type of martial art in question, the blood type distribution was as follows: 116 (38.4%) type A, 71 (23.5%) type B, 84 (27.8%) type O, 26 (8.6%) type AB, and 5 unknown (1.7%). It is assumed that the blood type frequency of Japanese is 37% for type A, 22% for type B, 32% for type O, and 9% for type AB. Thus, this result accords with the distribution of the ABO blood type of the Japanese, thereby suggesting that there is no relation between martial arts majors and blood type. In terms of the length of the athletes’ careers, 95 people had more than 15 years of experience, 169 people had 10 to 15 years, 29 people had 5 to 10 years, and 9 people had less than 5 years. Thus, those who had been active for more than 10 years represented 87.4% of the total. These individuals were considered experts, and we compared the number of athletes by blood type for each of kendo, judo, and sumo. Although the number of type A and type O respondents was the same in judo, the results show that the number of athletes with types A, O, B, and AB blood had the same tendency as the blood type distribution of Japan as a whole. Competition results were divided into two groups: those who participated in national tournaments (passing the qualifying round), including the world championship, and those who competed in local tournaments, prefectural tournaments, and at other levels below national tournaments. The results show that the achievements of type A athletes are not particularly remarkable. In fact, as the number of type A athletes as a proportion of the whole is large, it only looks large as a numerical value. More generally, regarding all blood types, the reason why more individuals from the same blood type have participated more frequently at the national level and above can be attributed to the selection bias of majoring in martial arts.In summary, performance and blood type have no remarkable correlation in terms of martial arts.Blood type and personality can be explained as a form of pseudoscience; therefore, some people will believe it. Research on blood types is indispensable for science. However, establishing how to bring novelty in thinking and suppress pseudoscience represents a task for future research. The most important aspect of achievement in the context of sport is the accumulation of daily training and effort.

In our study, we examined the psychological structure of junior high-school students participating in compulsory martial arts, focusing on their image of Kendo. Subjects of the survey included 389 students (156 boys, 233 girls, and average age 13.7 ± 0.8 years) enrolled in public junior high-schools in Chiba prefecture. In the 10 sections of the survey form, beginning with the phrase "What is Kendo," we asked the subjects to complete the sentences with what came to their mind. We further requested them to choose one sentence that had the strongest image of Kendo. Subsequently, text mining was performed on all the sentences we obtained, and the extracted words and phrases were factor-analyzed.Consequently, it became clear that the image of Kendo differs depending on whether the subjects had experience in Kendo lessons. Factors such as "Budo, Kiai, and Yuko-datotsu" were recognized by those with Kendo experience, while factors such as "Culture, Reigi (etiquette), and Budo" were recognized by those without Kendo experience. The factor of "Budo" was common for both sets of students with regard to their image of Kendo.

ABO血液型は日本ではごく一般的に受け入れられており,血液型性格診断や血液型占いなど娯楽にも用いられている。今日でもなお,血液型と人格は,スポーツの分野においても信じられており,インターネット上でも数多くヒットする。対峙する意見があり,結論に至っていない。本研究は,スポーツパフォーマンスと血液型の関係について,量的方法と文献を用いて考察するものである。私たちは,306名の武道(剣道,柔道,相撲)を専攻している学生を対象に,Web上でのアンケート調査を実施した。質問内容は,競技歴,競技成績,資格,そして血液型とした。回収率は,98.6%だった。血液型の分布は,A型116(38.4%),B型71(23.5%),O型84(27.8%),AB型26(8.6%),不明5(1.7%)であった。これは,日本人全体の血液型分布,A型37%,B型22%,O型32%,AB型9%の傾向と一致していた。このことは,武道種目に特化した血液型分布は存在しないことを示唆している。競技歴は95人が15年以上,169人が10年から15年未満,29人が5年から10年未満,9人が5年未満で,10年以上が全体の87.4%を占めている。10年以上を武道の熟練者とし,剣道,柔道,相撲の種目ごとと血液型を比較した。A型とO型の柔道の数値が同じではあったものの,分布は,A型,O型,B型,AB型の順に多く,この点についても,日本人の血液型分布と同じ傾向にあると言える。競技成績については,世界大会を含む全国大会以上(予選通過)と地方大会以下に区分し,血液型との関連を調べた。全国大会以上が最も多かったのはA型であるが,これはA型の競技者数が多いだけで,統計的な有意差はなかった。どの種目においても,全国大会出場以上の数が多いのは,この集団がもともと武道を専攻しているといった選択バイアスのためであると言える。つまり,武道系種目において,スポーツパフォーマンスと血液型には関係がないことが結論づけられた。血液型と人格については,擬似科学の分野でも説明されていて,それを信じる人もいる。血液型にまつわる研究はサイエンスとしては必須不可欠であるが,そのいっぽうで,いかに疑似科学を抑制するかの思考と方法論を見いだしていくかが今後の課題と言える。そして,スポーツにおいて最も重要なことは,日々のトレーニングとたゆまない努力と言えよう。
