Perception and management of risk by high altitude mountain climbers were investigated by qualitative analysis. Reports of high altitude mountain climbing collected from 3 books and 15 articles from mountaineering magazines were analyzed by the KJ method and transcripts derived from semi-structured interview of 6 distinguished Japanese expert mountain climbers were analyzed by M-GTA. The results indicated the following trends: 1) The desire for more fascinating high altitude mountain climbing routes inevitably leads climbers to face difficult and uncertain situations. 2) Such climbers are highly aware of the uncertainty derived from the high altitude environment and the exertion of climbing. 3) Because they are aware of this uncertainty, their decisions always waver between challenge and safety, and they always attempt to reduce the degree of risk. 4) Such efforts consist of two phases: risk reduction prior to the climb, and on-site avoidance of risk, each being characterized by mental simulation, avoidance of uncontrollable situations, and endeavours to salvage a positive result. 5) After the climb, ambivalent cognition between reflection on their optimism and achievement also emerges. Among all, mental simulation primed by on-site signs of risk, and risk evaluation from the viewpoint of controllability were regarded as keys to staying alive in high risk situations during high altitude mountaineering. Through this risk perception and management process, high altitude climbers possess a contradictory sense of “controllable risk” that enables them to engage in high risk activity. Overall, the characteristics of risk perception and management were similar among the materials obtained from books/magazine articles and interview transcripts. The characteristics of climbers' perception and risk management were rationalized by the characteristics of the natural environment in which they were climbing, and also from the viewpoint of the situated action. The possible application of these findings to risk management in outdoor sports was also discussed.

This study aimed to identify effective instructional methods for improvement of motor competence in children who do not excel at physical activity. For this purpose, a meta- analysis was conducted to integrate intervention studies designed to measure motor competence, and the effect size was calculated. The results suggested that children who do not excel at physical activity (i.e. under-achievers) were able to improve their motor competence to a particularly high degree. Among various sub-factors, the effect size of “acceptance” was the highest. We further examined instructional methods that might improve “acceptance”, and this revealed that “step-by-step instruction” and “interactions among learners” were considerably effective. These results suggest that an effective instruction method for children should include “step-by-step instruction”, which can motivate children to exercise on their own by offering tasks and an environment suitable for them in a stepby-step manner. “Interaction among learners” can be facilitated by providing opportunities to share information among students and to engage in group activities. Interactions can allow the group of under-achievers, who rarely receive attention in regular physical education (P.E.) classes, to feel recognized by learners. In conclusion, it is considered important in P.E. to work with a group that includes under-achievers and to foster a receptive atmosphere, instead of focusing on problems that emphasize the weakness of children. Practitioners should consider applying an ecological model of adaptive P.E. that emphasizes the relationship between the individual, the environment, and the task at hand.

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 study analyzed the momentum of the (hetero) sexualization of masculinity through physical culture magazines published during the 1930s-1980s in the United States, and also examined the social conditions caused by the corresponding changes. Since Foucault suggested the “repressive hypothesis” of sexuality, it has been widely recognized that, at some moment in modern history, same sex desire was identified as an inevitable identity, rather than just a deviant act, as considered previously.  However, several recent studies have questioned this hypothesis as being oversimplified. By reviewing previous research, this study examined the momentum of segregation between hetero/homosexual desire, which was observed in the 1950s, i.e. much more recently than generally recognized, and the obvious hetero-sexualization of the masculine ideal, which occurred after the 1970s.  The method employed was to compare 2 major physical culture magazines. To provide a contrasting perspective with regard to different sexuality, the first (famous) physique magazine, which began to be published in 1951 for potentially homosexual customers, was adopted to comparatively and diachronically examine the representation of male figures on the cover pages. This analysis revealed the following results:  1. During the 1930s-1950s, the ideal of masculinity was not yet hetero-sexualized and exemplified a broad range of desire which was not yet segregated as hetero/homosexual.  2. During the 1950s-1960s, physical culture magazines started to exclude non-heterosexual elements from their representations because of the risk that they could be potentially interpreted as homosexual.  3. The rise of the sexual minority rights movement in and after the 1970s, and the 1980s AIDS panic promoted homosexual visibility and expedited homophobia as a form of counter-action. This advance caused rapid and obvious hetero-sexualization of mainstream physical culture media.  In conclusion, the reason for the hetero-sexualization of physical culture magazines was a reaction to the increasing presence of homosexuals. It could be said that the rise of heterosexual self-consciousness itself was, to some extent, a counter to, and paradoxically caused by the creation and increasing awareness of homosexual identity. Moreover, these changes in the masculine ideal, and especially the examples before the 1950s, suggest the possibility of an ideal masculinity shared by hetero/homosexual males, which Sedgwick (1985) suggests is a homosocial continuum—namely, homosociality without discontinuity between homosocial and homosexual desire.

To encourage older adults to participate in exercise, it is important for self-governing bodies to divide them into subgroups according to exercise habit and to determine facts such as what they think about exercise and what type of programs would help them most. In Japan, however, few such schemes have been reported. This study aimed to clarify the process of ascertaining the characteristics of older adults and to establish a challenging means of encouraging continued exercise. The eligible study population was all residents aged 65-69 years living in Isobe town, Mie Prefecture, Japan (n = 675) , 460 (68.1%) responded to our questionnaire during a two-month period (November-December) in 2003. The respondents were divided into subgroups according to exercise frequency: those exercising twice a week or more (21.1%, Group A) , once a week (6.3%, Group B) , once or twice a month (7.6%, Group C) , and no exercise (65.0%, Group D) . Group A exercised because they believed they became healthier or achieved an improved fitness level. Group B undertook exercise as they regarded rapport as important, i.e. making friends at group exercise classes. To the question “Why don't you exercise?” Group C noted the lack of an exercise companion, and Group D noted low motivation. From the responses to “What type of approaches do you look for so that you might start exercise?” Group C suggested approaches such as an invitation to join an exercise class, or an introduction to an exercise instructor, and Group D suggested an exercise program that they could perform at home. Based on these results, a challenge for each group was established: to maintain the exercise frequency (Group A) , to increase awareness of the effects of exercise (Group B) , to participate more in group exercise sessions (Group C) , and to experience an easy-to-use home exercise program (Group D) . Future research is required to ascertain the effects of such challenges on exercise habit in older adults.

This paper clarifies some of the representations of female athletes at the dawn of women’s sports in Japan through an analysis of contemporary discourses regarding Kinue Hitomi, the first Japanese female Olympian. Previous studies have focused on Hitomi’s image as a deviator from the normative female image, differing from the representation of other “sports girls” associated with the image of ryosaikenbo (“good wife, wise mother”). However, the present paper focuses on Hitomi’s representation as the embodiment of the normative female image. What can be read from the aspect of “femininity” in the context of Hitomi, who was not included in the image of ryosaikenbo? The “prone episode” at the 1928 Summer Olympic Games is an anecdote that allegedly represents her “femininity”: Shortly after the runners finished in the women’s 800 meters, only Hitomi fell prone modestly while the other foreign runners lay on their back. This paper focuses on the episode and explores the significance given to it. Hitomi was represented positively as embodying mainly 2 types of female image: the healthy robust woman and the feminine graceful woman. The first image contrasted with the traditional one of the Japanese woman as a small, weak individual and was considered symbolic of the nationalism associated with Japanese modernization. When people viewed Hitomi in terms of the second image, they were clearly opposed to the concept that she was masculine, thus differing from the image of other “sports girls” who were casually associated with the ryosaikenbo concept in terms of their daily lives and careers. Hitomi’s achievement at the 1928 Summer Olympics had been widely admired for enhancing the national prestige of Japan. However, although her physique was praised at the time, its perceived meaning saw a transition from the “strong body” as a metaphor of modern Japan to the lady-like image represented by the prone episode. Through this process, multiple meanings assigned at first was transformed into a simple anecdote to illustrate that Japanese women are superior to Western women in terms of their “femininity”. It is ironic that Hitomi, whose gender had always been questioned because of her eminent athletic talent, came to be regarded as a typical Japanese “feminine” woman as a result of the prone episode, which had completely no relation to the arena of sport. Furthermore, after the war, as this contradiction between the feminine and the athletic physique faded, the prone episode turned into a casual representation of “femininity”, like the earlier representation of “sports girls”.

The purpose of this study was to specify the role of the low-rank acticept in human bodily thinking from a phenomenological viewpoint. An acticept is the gestalt of a percept with time factor and is a complex comprising a percept of action and phenomena resulting from the action. The word “acticept” is a compound of “action plus percept”, and “percept” means the content of perception. For the purpose of this study, the concept of a low-rank acticept is clarified by examining human bodily thinking as compared with verbal thinking. First, the author defines the problem, and then discusses the concept of the acticept as perception. On this basis, the formation and the role of a low-rank acticept is discussed, and the relationship between acticept and low-rank acticept is considered further. From this relationship, the prospect of classifying low-rank acticepts is demonstrated. As a result, the author describes the role of the low-rank acticept in human bodily thinking. The conclusions made are as follows. Human bodily thinking has a logical system different from that of verbal thinking. This type of thinking is necessary in order to create an acticept, and this becomes possible by gaining a low-rank acticept based on the logic of perception. From this low-rank acticept, image, explanation, and data are translated into our own practice, and we are able to realize each action. It is necessary to translate even procedural explanations into a low-rank acticept. These low-rank acticepts themselves continue being refined in such a way as to have wider applications, just as a word becomes precise. Therefore, in gymnastics lessons, it is necessary to pay attention to the originality of human bodily thinking, which is indispensable to movement practice, and furthermore to the individual low-rank acticept when teaching movement. Teachers should be able to transfer the low-rank acticept itself in order to make gymnastics lessons fruitful, not only theoretically but also practically.

When the boundary layer of a sports ball undergoes the transition from laminar to turbulent flow, a drag crisis occurs whereby the drag coefficient (Cd) rapidly decreases. However, the aerodynamic properties and boundary-layer dynamics of a soccer ball are not well understood. Here we showed that the critical Reynolds number (Recrit) of a soccer ball was 2.2 - 3.0 × 105. Wind-tunnel testing, along with visualization of the dynamics of the boundary layer and the trailing vortex of a ball in flight clearly demonstrated that both non-spinning and spinning curved balls had low Cd values in the supercritical region. We also showed that the Recrit of a soccer ball was lower than that (approximately 3.5 - 4 × 105) of a smooth sphere, due to the effects of its panels; this indicated that the aerodynamic properties of a soccer ball were between those of a smooth ball and a golf ball. Lateral images taken during high-speed kicking of a spinning curve ball (26 m/s; 8 rps) revealed that the separation point was approximately 120° from the front-stagnation point. In addition, the boundary layer between the top and bottom surfaces of the ball became turbulent. Top-view images taken during curved kicking (27 m/s; 7 rps) showed vortex deflection due to the effects of a relative difference in fluid speed caused by the spinning. The curvature of the ball was largely attributed to a lateral force generated by vortex counteraction. However, although the separation point showed left-right asymmetry in relation to the direction of travel (top-bottom symmetry on the images), it was approximately 116° from the front-stagnation point, which was similar to the separation angle during high-speed kicking of a non-spinning ball. In addition, the boundary layer became turbulent and the vortex region shrank during high-speed kicking of a spinning ball.

The purpose of the present study was to clarify the activity of kenjyutsu, the traditional physical culture in Japan, practiced as a match or sport in the latter period of Edo era. The object of this study was Sekiguchi-school of Takeda family that was transmitted in the Yoshino River area in the province of Awa (Tokushima prefecture) . The authors investigated the actual condition and character of kenjyutsu in those days using the historical materials of "nogeiko" (the outdoor meet of kenjyutsu) of the school. The findings of this study were summarized as follows : 1) The "taryu-jiai", in which kenjyutsu had come to be practiced as a match in the latter period of Edo era, was carried mainly by the common people rather than the people in the class of samurai and was activated all over the country. 2) "Nogeiko" of Sekiguchi-school of Takeda family was intended to open to the public from the beginning, and it was planned elaborately and practiced systematically. Almost all of the matches in the "nogeiko" were practiced by one person against one, though these were practiced with some formations supposing an actual battle, and there were "metsuke"(referee) who judged victory or defeat. 3) These matches were practiced under the free and large-hearted atmosphere beeing unbound to the ethical idea of Confucianism, and this "nogeiko" had a character of an amusement or pleasure of the common people. 4) This case means that kenjyutsu was practiced as an activity of a match or sport, whose style agreed with several melkmarls pointed by Guttmann, in the province far from the governmental center of this country. This is assumed not to be particular in the area of Tokushima prefecture but to be general in the localities of this country in those days. 5) Practice of kenjyutsu as a match or sport like this and accumulation of the experience,which became a basic condition to accept modern sports since Meiji era in japan, seems to make the rapid diffusion of it easily.

Restrictions on going out due to the novel coronavirus (COVID-19) pandemic have caused various psychological problems in many Japanese elementary school students, such as stress, anxiety, fear, helplessness, and anger. In this context, promotion of nature experience activities has been advocated, and have been reported to improve mental health. In addition, since a decrease in daily physical activity/exercise level is reportedly associated with a deterioration in mental health, the level of physical activity/exercise should be taken into account when evaluating the effects of nature experience activities. The purpose of this study was to examine the longitudinal effects of nature experience activities on the mental health of elementary school children during the COVID-19 pandemic, taking into consideration the daily level of physical activity/exercise. The participants were 130 fifth and sixth grade elementary school students (60 boys and 70 girls). The survey was conducted at 3 time points: just before the nature experience (pre-survey), just after the experience (post-survey), and 1 month after the experience (follow-up survey). Participants were asked to complete a questionnaire that assessed: 1) the degree of anxiety and limitation of activities related to COVID-19, 2) daily exercise level (hours), 3) social support level, 4) mental health level, 5) content of experiences in nature experience activities, 6) stress level. The participants were divided into high- and low-exercise groups according to their median scores. In the high-physical activity group, the pre-survey anger score (a component of mental health) was significantly higher than the scores for the post- and follow-up surveys. In addition, the self-confidence score (a component of mental health) for the postand follow-up surveys were significantly increased from the pre-measurement score, regardless of exercise hours. Therefore, it was shown that nature experience activities, while considering the influence of daily exercise, may be important for retaining calmness and confidence in daily life, even during the COVID-19 pandemic. However, there was no significant relationship between mental health and the content of nature experience activities. Therefore, it will be necessary to examine such content, which is closely connected with improvement in mental health.

This study focuses on the early theory of play in the school (<i>"Schulspiele"-Theorie</i>) of Konrad Koch, who advocated his "play movement" (<i>Spielbewegung</i>) at the Martino-Katharineum gymnasium in Braunschweig at the end of the 19^th century.<br> According to Koch's <i>"Schulspiele"-Theorie</i>, sports education shows isolated pupils how to conform to norms on their own initiative, i.e. following rules and norms as a requirement in sports, and also improves self-discipline. However, at least at the inception of the thesis of play in the school (<i>"Schulspiele"-Thesis</i>) written in 1878, the school was placed as an associate between "home and family" and "nation", where not only "lessons" were required, but inside the free gymnastic group (<i>freie Turnerschaft</i>) a community was to be built on the basis of an independent connection between teachers and students, as well as amongst the students themselves. The ideal form for this formatted collective was not further defined by Koch, who did not intend to have this collective focusing on "nation", but rather aimed to build this on the basis of a civil collective. Although at this time Turnern idolized anti-foreign nationalism, Koch admired the significance of the English style of sports education. One can say that the <i>"Schulspiele"-Theorie</i> based on a civil collective had aims that were quite different from gymnastics in school (<i>Schulturnen</i>) that valued nationalism.<br> Nevertheless, by the turn of the century, Koch had also published an extremely militaristic thesis. At this time, the collective building based on play in the school (<i>Schulspiele</i>) was to be described as something that was clearly dependent on the "nation". Future issues will focus on how and in which way Koch's <i>"Schulspiele"-Theorie</i> subsequently found its way into forms of authority in modern nations.<br>

The purpose of this study was to clarify the kinetic features of the upper limbs at different hitting-point heights (high, middle, and low) during baseball tee-batting. Twenty-three collegiate male baseball players (age: 19.8±1.3 yr, height: 1.74±0.04 m, weight: 74.1±6.2 kg, athletic career: 12.0±2.1 yr) participated. Three-dimensional coordinate data were captured using a VICON-MX system (12-camera, 250 Hz), and kinetic data for each hand were collected using an instrumented bat equipped with 28 strain gauges (1000 Hz). Three tee-batting heights were set for each subject based on the upper and lower limits of the strike zone according to the rules of baseball. Kinetic variables for the upper limbs, such as joint torque, joint torque power, and mechanical work, were calculated. The period of forward swing motion was divided into down-swing and level-swing phases. The results are summarized as follows: 1) The extension torque and positive torque power at each individual shoulder joint were significantly greater at the low hitting-point height than at other heights. 2) The positive torque power for extension torque at each individual elbow joint in the last half of the down-swing phase was significantly greater at the low hitting-point height than at other heights. 3) Negative power for adduction/abduction torque at each individual shoulder joint in the level-swing phase was observed at the low hitting-point height. 4) The mechanical work done by joint torque about the flexion/extension and adduction/abduction axes at the shoulder, the flexion/extension axis at the elbow, and the palmar/dorsal flexion and radial/ulnar flexion axes at the wrist showed large and positive values, and differed significantly among hitting-point heights. These results indicate that 1) the flexion/extension torque at each individual shoulder joint contributes greatly to adjustment of the translational movement of the bat in the vertical direction during the down-swing phase, 2) the adduction/abduction torque at each individual shoulder joint exerts a larger proportion of the longitudinal force of the bat to withstand centrifugal force at a low hitting-point height than at other heights in the level swing phase, and 3) consequently, it tends to be more difficult to adjust the bat to the hitting-point at a low height in comparison with other heights.

The purpose of this study was to clarify the kinematics of the jump floater serve in volleyball to provide basic data for research. The jump floater serve motions of 9 female volleyball players (body height: 174.4±6.2 cm, body weight: 67.7±6.1 kg, age: 23.6±4.6 yr, career: 14.4±5.1 yr) were recorded using a motion capture system with 10 cameras (500 Hz). The three-dimensional coordinates of retro-reflective markers on the volleyball were also collected using a motion capture system. The primary variables examined were the hand velocity of the swing arm at impact, the velocity and angular velocity of the volleyball after impact, the joint angles of the swing arm and torso, and the segment angle of the lower torso during the jump floater serve. The main results were as follows. 1. The speed of the volleyball was about 14 m/s, and the spin of the volleyball was about 1 rps. 2. No significant correlation was found between the number of volleyball rotations around each axis and the impact parameters of the swing hand. 3. The maximal right rotation angle of the torso joint in the jump floater serve was smaller than that of the spike motion. 4. The abduction angle of the shoulder joint at ball impact in the jump floater serve was similar to that of a spike motion. 5. From the end of take back to the middle of the serve motion, the standard deviation in the abduction angle of the shoulder joint was notably large. 6. The maximal external rotation of the shoulder joint was smaller in comparison with a baseball pitch or a tennis serve. 7. The extension angle of the elbow joint at impact was smaller in comparison with the volleyball spike motion.

This paper examines (1) the profile of Dr. Kenzo Futaki, (2) why he advocated the abdominal breathing method, and the purpose and effects of the method, (3) how the Futaki breathing method is performed, and (4) how it compares with the Okada method. The Futaki breathing method involves abdominal breathing, and was originally advocated because anyone could use it. Futaki clearly indicated that his method was not original, but was inspired by, and borrowed from, Atsutane Hirata's method. Hirata's method is a return to an Eastern style of breathing technique, as compared to the practices of the time, which were largely Western-inspired training methods, i.e. with little emphasis on breathing at all. Futaki was a boy of frail constitution until he tried Hirata's method when he was 16-17 years old. He attributed his newfound health to this method. Later he became a doctor, and researched the method further. He found medical/scientific support for the Hirata method. The Futaki method, abdominal breathing, differs significantly from the Okada method, known as reverse breathing or chest-type breathing.

The purpose of this study is to clarify the transformation that occurred in a school (ryuha) of swordsmanship in the domain of Ohmura, Nagasaki, at the end of the Tokugawa period in Japan, focusing particularly on the invitation extended to Saito Kannosuke, one of the leading instructors in the Shinto Munen-ryu (school of swordsmanship), in 1854. This paper was based mainly based on two historical materials: Shugyo-chu Shohan Houmei-roku (1849) and Kuyo Jitsuroku (1849-1855). Ohmura Sumihiro, the 12th domanial lord, and Egashira Kandayu, his chief retainer, were tacitly interested in the utility of swordsmanship in Ohmura, and actively proposed the transformation of a school of swordsmanship. In 1854, they invited Kannosuke to act as the swordsmanship instructor. Kannosuke was the third son of Saito Yakuro, a famous instructor of the Shinto Munen-ryu, who had established and managed the Rempeikan, a swordsmanship school (dojo) in Edo. Saito Yakuro's eldest son, Shintaro, had embarked on a journey throughout the domains of Japan in order to train and practice against other warriors there. These training and practice were known as kaikoku-shugyo. Shugyo-chu Shohan Houmei-roku indicates that Shintaro visited many feudal domains, including Ohmura. Ohmura Sumihiro and Egashira Kandayu then became interested in the technique of the Shinto Munen-ryu, which was taught at the Rempeikan, because they considered it to be useful for actual fighting. Afterwards, they succeeded in inviting Kannosuke in 1854, and he became the instructor employed by the domain of Ohmura. His duty was to promote the training of the Shinto Munen-ryu with warriors in Ohmura. In 1855, the Itto-ryu and Shinkage-ryu instructors of swordsmanship were dismissed and forced to stop their teaching. According to Kuyo Jitsuroku, this transformation from the Itto-ryu and the Shinkage-ryu to the Shinto Munen-ryu occurred over a period of six years (from 1849 to 1855). It was brought about to achieve the political ambitions of Ohmura Sumihiro and Egashira Kandayu.
