The purpose of this study was to investigate the hypothesis that pole vaulters regulate their stride length during the approach run, and to determine the effects of differently regulated gait patterns on take-off velocity and performance. The approach runs and take-off movements of ten male pole vaulters were analyzed.   It was revealed that each pole vaulter regulated his gait pattern in the approach run in order to adjust for the distance to the toe-box at take-off, in a similar way to the technique used by long jumpers and triple jumpers. The standard deviation of the distance to the toe-box at take-off and the length of each step in the approach run showed no significant difference between high- and low-performance-level vaulters. However, vaulters with a higher personal best started to adjust their stride length earlier than vaulters with a lower personal best, and had finished most of their run-up adjustment by the second to last stride. To clarify the effect of run-up adjustment on the velocity in the take-off phase, the subjects were classified into three groups according to the timing of their adjustment: Early, Medium, and Adjacent. It was found that the take-off velocity of Early Adjusters tended to be higher than in the other groups, and that Adjacent Adjusters had the lowest velocity.   The present findings suggest that in order to perform well in the pole vault, it is important for the vaulter to regulate his stride length in the approach run, rather than performing a stereotyped run-up. In addition, regulation of stride in the first half of the approach run and avoidance of stride regulation immediately before take-off seem to be more effective for achieving better performance.

The purpose of the present study was to clarify the profiles of the lower limb and trunk motion during baseball pitching in relation to their differences between the wind-up and the set positions, and to determine how the ball pitching velocity can be increased in the set position. The subjects were 12 high school baseball pitchers (age: 16.4±0.5 yr, height: 173.7±4.8 cm, weight: 64.8±8.1 kg). Pitching was assessed using a three-dimensional motion system and 2 multicomponent force plates. It was found that 1) the maximum and average pitched ball velocities were significantly lower in the set position than in the wind-up position, 2) the maximum ground-reaction force of the pivot and stride legs and the impulse of pivot during the stride phase (from the time of maximal stride knee height to the time of maximal anterior push-off force) were significantly lower in the set position than in the wind-up position, and 3) the maximum upper torso/trunk twist angular velocity and the pelvis/upper torso angular velocity at moment of the stride foot contact were significantly lower in the set position than in the wind-up position. These results indicate that 1) the ball pitching velocity in the set position is lower than in the wind-up position. In addition, the factors associated with this lower ball velocity are suggested to be 2) decreased momentum of the pivot leg and 3) decreased rotation motion of the trunk during the arm acceleration phase.   Therefore, in order to increase ball pitching velocity in the set position, increasing the moment to the rear of the pivot leg during a short period and improvement of lower limb strength/power with the extension movement of the hip and knee joint may be important factors.

The present study had 3 objectives. First, we aimed to categorize the effectiveness of participation in school athletic clubs in accordance with findings from preceding studies (study 1). Second, studies on the effectiveness of athletic club activities were to be organized by generation with the changes observed in each generation also described with a view towards clarifying research tasks (study 2). Third, we aimed to clarify the effectiveness of athletic club activities that had not yet been demonstrated in previous research (study 3). In study 1, when we categorized the effectiveness of athletic club activities, we confirmed the construct, the subscale, and the observable variable that determined effectiveness in each study. Each concept was grouped based on similarity and made types having higher degree. The categories we derived were "school adjustment"; "scholastic ability"; "character"; "stress and mental health"; "psychosocial development"; "physical growth and development"; "sport as a habit"; "attitude towards sports"; "fatigue"; "lifestyle"; and "others". In study 2, when we investigated the transition of studies on the effectiveness of athletic club activities, we focused on the problem establishment in these studies. This was considered while examining the association between each problem establishment and social background or policies of the day. As a result, at first, researchers continued selecting students who participated in athletic clubs as appropriate subjects for examining the effectiveness of physical exercise or sports activity. Second, researchers are also interested in the negative effectiveness of participation in athletic clubs. Positive trends are particularly strong for "school adjustment" and "stress and mental health" studies conducted after 1998. Third, studies that demonstrated significance or effectiveness of athletic club activities increased after 1983, and the effectiveness that were determined diversified since that time. Researchers found out various significance and effectiveness of athletic club activities, and recognition of the potential for athletic club activities to address issues also increased. It can be said that we researchers don’t reach a common understanding on the significance and effectiveness of athletic club activities. In study 3, we brought attention to the effectiveness of athletic club activities that had been overlooked in previous studies by comparing effectiveness as determined in empirical studies how it had been determined in theoretical studies. Unnoticed effectiveness of athletic club activities was the acquisition of abilities and attributes necessary for developing sports society and culture.

This paper examines the relationship between ethics and the Japanese martial arts (budo). The issue of this relationship has been studied mainly from the standpoint of history, and has not been much researched from the standpoint of practitioners. Therefore, in this paper, I describe how practitioners acquire the ethics of budo by approach the topic through the concept of “becoming,” as maintained by Sakuta, Yano and Kameyama, with the intention of clarifying the inner processes adopted by practitioners. For this purpose, I observed participants at an aikido dojo. Generally, participant observation means describing the experiences of field work objectively. In this paper, however, I describe the aikido practitioners' inner experiences, and from that I try to clarify the practical aspect of the relationship between ethics and budo. The findings of my study were as follows. In the practice of aikido, the practitioners are instructed to harmonize with each other and are taught that this feeling of harmonization is the “Aikido spirit”. Not only by developing this feeling, but also an awareness that the mind and body don't match each other, and control of mind and body cannot be achieved together, aikido practitioners gain a new view of the world, and reflect on everyday life and communication with others through the feeling gained in the dojo. Aikido practitioners acquire ethics through constant reflection on mind and body. Such reflection is indispensable in order for practitioners to embody morality. I think it is possible to consider fundamentally the roles of modern Japanese martial arts by clarifying these processes.

本研究は、野球初心者が全力投球を反復した際の球質の動態を明らかにすることで、その際に内在する諸問題について検討し、特にスピードトレーニングの投球練習における適正反復投球数について検討することを目的とした。実験試技は、野球初心者である男性2名に対して、屋内において捕手方向に各々の最大努力度によって、フォーシームの握りでストレートを投球させた。投球数は20球1セットとし、合計5セットの計100球の投球を行わせた。その結果、投球数の増加に伴い、ボール速度が減少した。その際、セット内における球速および回転数の変動が大きかった。さらに、野球経験者と比較すると、球速が低く回転数が少なかった。よって、野球初心者はボール速度を増大することに加え、回転数を増大させること、球質を安定させることもトレーニング課題となりえることが想定される。また、野球初心者では、21~40球目にボール速度の大きな減少がみられたことから、スピードトレーニングの投球数は20球までを適正反復回数の目安とすることで、より効率よく球速をはじめとした球質の向上への効果を期待できる可能性が示唆された。

The purpose of this study was to reconstruct a cognitive appraisal scale for high school athletes (Shibukura and Mori, 2004), and to examine the scale's reliability and validity. The subjects were 1370 first and second year high school athletes (903 males and 467 females). They were required to complete a questionnaire that consisted of a cognitive appraisal scale and a stress-coping scale for high school athletes. In this study we tried to devise a cognitive appraisal scale that contained “threat” and “challenge” as a primary appraisal and “controllability” as a secondary appraisal. First, as a result of factor analysis, it was revealed that a cognitive appraisal scale for high school athletes consisted of the three factors mentioned above. In this way, the cognitive appraisal scale was reconstructed. Second, the reliability of the scale was examined through the split-half method and the test-retest method. Furthermore, the content validity and the factorial validity were verified. Finally, multiple regression analyses were performed in order to examine the relationship of cognitive appraisal and coping. It became clear that a cognitive appraisal scale explained stress-coping, and the scale's predictive validity was supported. Consequently, a cognitive appraisal scale for high school athletes that contained “challenge”, “threat” and “controllability” was reconstructed, and it was considered that this scale would contribute to clarification of the psychological stress process and effective stress management.

The purpose of this study was to clarify the principal factors related to shot situations that affect the outcome of goalkeeping saves in soccer and to build a regression formula that would predict the difficulty of saving a shot. The samples were 551 shots at goal in the 2010 FIFA World Cup in South Africa. The shots data were collected using game performance analysis. For statistical processing, the principal factors affecting the outcome of a save in soccer were revealed using logistic regression analysis. The principal factors that influenced the results of a save attempt were: the duration between initiation of the shot and when the ball reached the goal, the presence or absence of a defender in front of the shooter, the presence or absence of a defender located lateral or posterior to the shooter, the part of the body used to perform the shot, i.e. the head or the leg, the type of shot, i.e., a liner, a lob, or a grounder, the shot course in a mediolateral direction, the shot course in a vertical direction, the presence or absence of a change in the direction of the shot by other players, the shooter's position angle in relation to the goal line and the line from the goal post to the shooter, and the distance from the center of the goal to the ball when the ball reached the goal line. In addition, a regression formula was constructed to predict the difficulty of the save by combining the odds ratios of the main factors. It was verified that the difficulty in making a save could be accurately predicted using the regression formula (84.8%). As a future task, using our regression formula, it would be practically important to develop predictors for evaluating the ability of a goalkeeper.

In recent years, the way university sports are conducted has been under discussion. In particular, there is some concern about the balance between studies and competitive activities, which is important when considering the future of university sports in Japan. As no previous research has focused on sports recommendation admissions to universities in Japan, the present study first attempted to clarify the way in which this system has developed.  The following findings were obtained:  1. In Japan, even before the recommendation admission system was officially approved, athletes had been given preferential treatment in entrance examinations, which was not disclosed to the public or stipulated in application guides.  2. Soon after the recommendation admission system was officially approved, campus disputes worsened, which caused the preferential admission treatment of athletes to be severely criticized, making it difficult to continue with the conventional system any longer. Accordingly, during the period from the late 1960s to the early 1970s, universities abolished the preferential treatment given to athletes in entrance examinations.  3. Since the recommendation admission system was officially approved in 1967, the faculties of physical education at private universities, among others, started to actively admit athletes based on recommendation. These physical education faculties selected students based on physical skill tests to secure competent athletes. Thus, by matching the admission policy of the faculty with the sporting abilities of athletes, universities were able to secure competent athletes without having to impose a special admission quota for athletes.  4. In the 1980s, private universities played a leading role in conducting entrance examinations with a special admission quota for athletes. Waseda University launched the Special Selection System for Physical Education Major, which introduced a special admission quota for athletes, specified the athletic events and performances, and made the selection process widely known to the public. In conducting this selection, however, the university faced a dilemma of whether or not to employ it as the system for strengthening their sports teams.  5. In 1987, the Ad Hoc Council on Education, an advisory body of the Japanese Government on education, recommended that assessment of sports activities be taken into consideration in entrance examinations. The 1989, the Guidelines for University Entrance Examination, revised in accordance with the Council's recommendation, listed “adequate assessment of activities in sports, culture, etc.” as a selection method for university admission for the first time.

This study was conduct to understand how women's physical education was promoted during the development of Japan, focusing especially on the Taisho era (1912-1926). First, I reviewed critical opinions about physical education for women prevalent during this period, in order to reveal details of difficulties in promoting it. Secondly, through collection of relevant documents, I examined the measures for promotion of women's physical education that had been discussed during this period. Thirdly, I reviewed the criticism of these promotion measures, in order to reveal the tendencies and problems prevalent at the time.   On the basis of these reviews, I consider that the main reasons why the promotion of women's physical education was not successful in the Taisho era were: 1) women's physical education was not consistent with the traditional social norm of the time, 2) theoretical studies of physical education had not yet been developed, and 3) people at that timetended to regard ‘unhealthy-looking’ women as beautiful (for example in the works of Takehisa Yumeji). Since it was difficult to solve these problems, some advocates tried to promote women's physical education by emphasizing the beneficial effects of gymnastics rather than conducting theoretical studies. This was promoted by proactively creating a new concept of women's physical education such as appreciation for ‘health and beauty’. The measures for promotion of physical education for women in the Taisho era placed emphasis on advertising physical education more effectively rather than improving it qualitatively. The promotion of women's physical education in this manner was criticized by other advocates of physical education, and I consider that this was one reason why the quality of women's physical education remained low.

In high school baseball games, choosing when to bat influences the likelihood of winning, teams batting second having a significantly higher winning percentage. Three hypotheses can be considered for explaining this trend: the weaker school chooses to bat first (Hypothesis 1), an additional strategy change can favor the team that bats second (Hypothesis 2), and a tied score in a later innings favors the team that bats second (Hypothesis 3). However, to our knowledge, no study has directly tested these hypotheses. Therefore, we analyzed data for all 972 games of the Japan national high school baseball championship tournaments between 1996 and 2015, and the following 5 results were obtained. There was a trend in past Koshien tournaments for weaker schools to bat first when playing against stronger schools (52.8 percent, P = 0.091). The winning percentage for the former was 35.5%, which was significantly lower (P <0.001) than the chance level (50%). In addition, the winning percentage for batting first in games between schools with similar levels of past performance was 44.7%, which was significantly lower (P = 0.025) than the chance level (50%). In games between schools with similar levels of past performance, the winning percentage varied for teams batting first when the bottom half of each inning ended in a tie. In games in which teams were tied at the end of the 6th and 7th innings, the winning percentage of the team batting first was significantly lower (36.0%, P = 0.033; 34.0%, P = 0.016). In other words, Hypothesis 3 was supported, Hypothesis 1 was partially supported, but Hypothesis 2 was not supported. These findings indicate that the higher winning percentage for batting second is attributable to the fact that the weaker school regards itself as inferior to its opponent and therefore chooses to bat first (i.e., the weaker school chooses to bat first) and that the psychological pressure faced when batting first versus batting second differs when there is a tie in the later innings (i.e., a tied score in later innings favors the team that bats second).

The aim of the present study was to explore the correlation between women's physical education in schools and foot binding in Taiwan during the initial stage of Japanese colonization (1895-1906). Based on historical materials such as Taiwan Nichinichi Shinpo (Taiwan Daily Newspaper), Taiwan Kyoikukai Zasshi (Taiwan Education Magazines), and Taiwan Kyoiku Enkakushi (Taiwan Education Development Magazines), we tried to clarify how Japanese colonists carried out physical education in the period before 1906 when female students still had bound feet. The proportion of women with bound feet was as high as 60%, and this led to practical difficulties with physical education. Because of these difficulties, physical education was replaced by suitable games (including a form of dancing activity; for example, marching play (Kōshin-yūgi) and facial expression play (Hyōjō-yūgi) between 1895 and 1906. The practice of games in physical education was thus firmly established during this period. The second affiliated Kokugo school (Japanese school), as a role-model school in Taiwan, always practiced games and general gymnastics in consideration of foot-binding. Thus, the teaching experience during this time can be viewed as an embryonic period for the general gymnastics that emerged later.

The present study was conducted to clarify the roles of coaches in sports instruction and the essentials of these roles. Up to now, there has been no unified definition of coaching, and the conditions and grounds for selecting coaches and analyzing them collectively have remained unclear. In addition, logically, “induction” rather should be “extracted,” and the existing intelligence of the contents (intension) of the concept can be logically assumed. Accordingly, this approach seems inappropriate for revealing the essence of coaching. In order to overcome this problem, this research classifies into occasions of entities and consistence of existence. Under the subject of existence, entities theoretically transcend this through individualization, and this method is used to reach the existence of entities. As a result of this consideration, coaches first “tame” athletes to a system of physical techniques in order to address specific items, and then they endeavor to maintain the same level of play. It was clarified that coaches are specialists who are able to help athletes “transcend” from their current conditions. Moreover, coaches can using external force to compel a “physical change” in athletes, as leaders who can control athletes intelligently and actively, using a process that consists of and production based on theoretical knowledge. Thus, coaching involves the use of “compelling power” to rise from restrictions under specific conditions, and to encourage constant excellence.

我が国の運動部に見られる「体罰」や「しごき」といった暴力的行為のルーツとして従来語られてきた所謂「軍隊起源説」には、1930年代にミリタリズムの影響で運動部が変容していったとする戦前起源説と、戦後に軍隊経験者が運動部に軍隊の行動様式を持ち込んだとする戦後起源説がある。本研究者による戦前・戦後期の運動部経験者に対するインタビュー調査等では、その2つとも当てはまらない旧制高校、2つとも当てはまる私立大学予科、戦前説のみ当てはまる師範学校等々、その実相は多様で複雑である。本研究では、「軍隊起源説」のように歴史上のある時点に起源を設定し、その一点から現在の問題状況が生起したと把握する理解を退け、かかる俗説による説明を日本の社会はなぜ共有、或いは許してきたのかを、戦後から高度経済成長期における「戦中派」の意識の変容を焦点に考察する。そこでは、軍隊経験に積極的な意味が見出されていく時期に、「戦中派」のスポーツ指導者が自身の軍隊経験とスポーツを結びつける言説が表明されていくことに注目する。

Focusing on the theory of the “principle of ju” that generates movements and techniques reflecting the proverb “softness overcomes hardness: ju yoku go wo seisu”, we discuss the relationship between the movement of modern judo practitioners and its sportization, in order to grasp the current situation of judo in Japan. It was found that there are 3 levels among contemporary Japanese judo practitioners: (1) those who practice judo in the context of a competitive sport while being aware of the tradition, (2) those who practice judo purely as a competitive sport, and (3) those who practice the traditional skills of a martial art. It is widely recognized that those at level (1) tend to neglect, whereas those at level (3) tend to emphasize the arts of judo. Also, older judo practitioners tend to emphasize the proverb “softness overcomes hardness”, but this is unrelated to the length of time spent training and the dan level of the practitioner. Many present day judo practitioners regard judo as a competitive sport, suggesting that – in terms of movement – Japan’s judo tradition being lost. On the other hand, however, it has also become clear that those who love judo and practice it with an attitude not obsessed with victory or defeat or of improving their skills, attach great importance to “softness overcomes hardness”. In order for judo to continue to remain a “physical exercise culture proclaiming the place of traditional Japan in a global world”, it can be suggested that the challenge lies in the rebuilding of the interaction with judo as a martial art that aims for “development of skills” with a loving attitude that differs from competition, while ensuring that some aspects remain competitive.

The purpose of this study was to determine the impact conditions that enable a batter to hit a pitched ball toward the opposite field. Three-dimensional finite element analysis was used to construct a model for the impact between a baseball and a wooden baseball bat, and a series of simulations were conducted with various bat angles and under-cut distances. The bat angle at ball impact was set in a horizontal range from -31 to 20° and a vertical range from 0 to 51° with a 3° interval. The under-cut distance was altered by changing the vertical angle of the line of impact in a range from 0 to 30° with a 5° interval. The velocity and angle of projection of the batted ball were determined for each simulated condition. The simulation model was validated by comparing the simulation outcome with the corresponding experimental data obtained from opposite-field hitting practice performed by collegiate baseball players. The results showed that when a batter intends to hit a ball toward a given horizontal angle in the opposite field with the highest speed, the batter should impact the ball with the bat facing about 60% of the horizontal angle toward which to launch the ball and with the line of impact angled upward at 5~10° from the horizontal plane. In addition, the horizontal angle of the batted ball and the velocity of the batted ball were found to change systematically when the vertical angle of the line of impact and the vertical bat angle were altered: For a given horizontal angle toward which to launch the batted ball, there was a trade-off relationship between the vertical angle of the line of impact and the vertical bat angle.

This study investigated Korean traditional archery in the 18th century by reference to the Eosagopungcheop (records of the old custom of King's archery) of King Jeongjo, who was known for both literary and military accomplishments in the Joseon era. Through these records, we were able to obtain information on the types of archery, the variety of targets and arrows, the methods of scoring and recording, and the features of traditional archery. The findings were as follows: 1.  The arrows employed were Yuyeopjeon (willow-leaf arrow), Soso (small arrow), and Cheoljeon (iron arrow). All of them featured in examinations for military officers. 2.  In terms of quantity and frequency, the willow-leaf arrow was used most commonly. 3.  The small arrow was considered the piece arrow, which was a weapon unique to Korea. 4.  It became clear that the iron arrow, which was very heavy and thick, was used to break shields. It seems that this type of arrow was considered the most important for military officer examinations, because it played an important role in breaking down the enemy's defense in Korea, depending on the archery tactics. 5.  The targets employed included cloth targets, leather targets and a variety of other types. 6.  It was clarified that in terms of accuracy, targets were ranked in order of size. On the pierce leather target standard, the other targets appeared to be named ‘Fragment’, ‘Small’, ‘Palm’ in descending order of size. 7.  Each type of arrow was paired with a specific target. The willow-leaf arrow was paired mainly with leather targets. The small arrow was paired with both leather and cloth targets, and the iron arrow was paired with shield or club targets. 8.  According to the records, a practice session comprised basically 10 sequences, each involving the shooting of 5 arrows. 9.  The scoring system differed depending on the type of target. For leather targets, the score was separated into two hit zones: the center and the surrounding area. However, the score was not separated in this way for cloth targets. 10.  The willow-leaf arrow used on leather or club (cudgel) targets was the item to compete in accuracy. The small arrow, used mainly on cloth targets, was used in contests held on shooting ranges. The iron arrow, used mainly on shields or clubs as targets, was used for determining destructive power and accuracy. 11.  The inscriptions in the records are divided as to whether the shooting sequence was single or multiple. 12.  The records reveal that Korean traditional archery was still widely practiced at the end of the 18th century, when firearms had become common in all parts of the world.

The purpose of this study was to investigate the norm for supporting play by athletes in team sports, which has so far lacked implicitness, having been regarded spontaneity. The investigation involved analysis of the “authority” of Michael Jordan (hereinafter shortened to “MJ”), who has had a reputation as being one of the best athletes in history. Initially we tried to extract a sense of values from MJ himself and references to his reputation. From this, we clarified a standard of value judgments, and then finally produced a suitable universal normative principle common to all athletes. Although there were insufficient data to draw firm conclusions, the sense of values derived by an athlete appeared to be derived from evaluation of “whether one can utilize one's own talents.” It became clear that while this leads to “correct” play, this evaluation standard contributes to the formation of an “independent strong self” that can “exert positive freedom.” On the other hand, it was also concluded that not only did this “positive freedom” control the evaluation standards of athletes, but also functions as the “normative principle” that one should acquire by forming one's own creativity and identity. At the same time, it was suggested that “positive freedom” is the driving force that allows athletes to become “ignorant” through independent and strong self-belief, The present findings indicate that disregarding any mystique or secrecy about the underlying ability in athletes, and transcending the rule of thumb can contribute to execution of play by athletes in team sports, acting as a signpost when confronting any problem that is complicated, erratic or filled with uncertainty.
