This article expands some historical perspectives on “popular sport” based on the following three case studies: (1) Interactions between foreign sport and rural sumo wrestling in the village of Shiojiri, Nagano prefecture, during the Taisho Democracy Period. (2) The historical development of traditional Japanese boat racing in the area known as Tamaeura in Hagi, Yamaguchi prefecture. (3) Modern reconstruction of folklore and physical competition following the agrarian revolt known as the “Chichibu Jiken” in Saitama prefecture in 1884. Having to compete with festive folklore, the main emphasis of physical education and sport in modern Japan was placed on civilization and enlightenment. Thus, the establishment aimed to develop thrifty and hard-working citizens who served the state and capital. However, there were moments when opposition, deviation and autonomy occurred in the daily lives of the masses, and it was clear that they could not be controlled unitarily. For the masses, traditional physical competition and sport were not only hobbies, forms of entertainment or means of improving self-discipline or physique, but also provided a medium for expressing their desire for solidarity and social growth. What is “popular sport”? It is not a solid cultural entity but a complete panorama of physical competition and sport from the viewpoint of the masses. The “history of popular sport” aims to analyze and represent this phenomenon historically in relation to the total sphere of daily life. In such research, the concept of the masses has significance in terms of “method”, “standpoint” and “strategy”.

The purpose of this study was to clarify the exertion of torque and motion related to the generation of mechanical energy in both hip joints during baseball batting. The participants were 98 male amateur baseball players (body height: 172.6±5.6cm, body weight: 70.3±8.1kg, age: 19.0±1.9yr, career: 11.0±2.8yr). The batting motion was recorded using a motion capture system (10cameras, 250Hz), and the ground reaction forces acting on each foot were estimated using 2 force plates (1000Hz). Hip joint angles were expressed as Euler angle of the thigh relative to the lower torso. Hip joint torques were calculated using inverse dynamics. Other kinetic variables–e.g. hip joint torque power, mechanical work by hip joint torque–were also calculated. The main results were as follows: 1. Throughout the analysis phase, there was no significant correlation between the bat head speed at impact and the angles of both hip joints. 2. For the hip joint on the pitcher side, the generation of mechanical energy by flexion and adduction torque was large during the phase before maximum pelvis rotational velocity. 3. For the hip joint on the catcher side, the generation of mechanical energy by extension torque was large in the phase before maximum pelvis rotational velocity. These results suggest that there are no differences in the kinematics of both hip joints depending on the bat head speed at impact. In addition, it is indicated that the ability to exert flexion and adduction torques for the hip joint on the pitcher side and the extension torque for the hip joint on the catcher side during baseball batting motion contribute to the generation of mechanical energy.

Japanese married women only began participating widely in sports after the Tokyo Olympic Games in 1964. It is often said that sports activities by housewives indicated their liberation from isolated domestic life, thereby promoting gender equality. However, close examination of the systemic characteristics of the 'Mothers' Volleyball' movement (based on its ideology, competition rules and the nature of its routine activities) has shown that these activities possess both a recycling structure that releases housewives from their homes temporarily and reflects the participants' 'housewifeliness', thereby reinforcing the separation of roles between the sexes.<br> In order to clarify by whom and for what purpose this recycling structure was created, this paper focuses on the organizing bodies (sponsor organizations, supporting companies and other bodies that organized and ran the national championships, incorporating the systemic characteristics of Mothers' Volleyball), analyzing the reasons for their involvement with the movement and the benefits they derived from it. The results show that the periodic reflection of housewifeliness, which housewives needed in order to continue in their role as housewives, was necessary for the economic and social benefit of all the organizations involved, and that this is why these organizations committed themselves to the movement.<br> Participating in sports freed housewives from the routine of daily home life, and activities such as helping to organize competitions promoted their socialization and changed their image from that of 'isolated housewife' to 'sporting housewife' and further to 'independent housewife'. The recycling structure mentioned earlier can therefore be thought of as being a directional spiral, and the organizing bodies that ran the national championships can be said to be its drivers.<br> This spiral, which helped to reproduce 'housewifeliness', supplied society with good-quality labour for sustaining Japan's rapid economic growth, which was a political issue in the 1970s. The participation of housewives in sports as one of the activities of parent-teacher associations and women's associations can also be said to have contributed to local revitalization, another political topic at that time. Meanwhile, making sports one of their routine, repeated activities made housewives' lives more satisfying, so that Mothers' Volleyball acted as a medium for the formation of a conjugate relationship between housewives and society.<br>

The purpose of this study was to examine muscle activities during seven traditional different free dynamic exercises designed to strengthen the abdominal muscles. Eleven adult men with experience in weight training were asked to perform three repetitions of LSU, BSU, TSU, TC, RSU, LR and SLR. Activities of the upper rectus abdominis (URA), lower rectus abdominis (LRA), external abdominal oblique (EAO), and rectus femoris (RF) during the hip flexion and hip extension phases of each exercise were examined by electromyography (EMG) and analyzed using root mean square (RMS) values. The following results were obtained: (1) The mean RMS values for the URA were larger during the RSU and SLR than during the other five exercises. The value for the same muscle was larger during the TC exercise than during the LSU, BSU, TSU, and LR exercises. The mean RMS value for the LRA was largest during the RSU exercise, while that during the SLR exercise was larger than those during the LSU, BSU, TSU, TC, and LR exercises. (2) The mean RMS value for the EAO was largest during the SLR exercise, while that during the RSU exercise was second-largest and that during the TSU exercise was third-largest. The mean RMS values for the RF were larger during the RSU and SLR than during the other five exercises. The smallest value for this muscle was recorded during the TC exercise. (3) In most of the exercises, RMS in the hip flexion phase was larger than in the hip extension phase, and each muscle exhibited a knee flexion phase/knee extension phase ratio of between 0.5 and 0.8. However, the ratio for EAO and RF exceeded this range. (4) The muscle activity for the RF muscle in the RSU and SLR exercises was large, implying excessive stress for the lumbar vertebrae. Nevertheless, these exercises induced active muscle activity, and appeared desirable to perform with sufficient attention to safety.These results suggest that RSU and SLR exercises are the most effective movements for stimulating the URA, LRA and EAO. Moreover, TC is an effective movement for training the URA, and TSU is an effective movement for training.

The purpose of this study was to investigate the relationship between motion and ball spin in tennis serves. Ten male university tennis players participated. The three-dimensional coordinates of the players performing flat, kick and slice serves were collected using a motion capture system with 8 cameras (250 Hz). Similarly, the three-dimensional coordinates of reflective markers on the ball were also collected (500 Hz). The primary variables computed were: racquet face velocity and direction at impact, velocity and angular velocity of the ball after impact, hitting point, angles of the upper limb joints, and segment angles of the upper trunk. The differences in racquet face velocity among flat, kick, and slice serves were divided into the following terms: 1) ΔVposture: A difference in velocity resulting from a change in upper trunk posture, 2) ΔVswing: A difference in velocity resulting from a change in arm swing (kinematics of the upper limb), 3) ΔVutrk: A difference in velocity resulting from a change in upper trunk translational and rotational motion. Repeated measures ANOVA (p<0.05) with Bonferroni multiple comparison was used to evaluate the effects of changes in form (with differences in ball spin) on each parameter. The findings are summarized as follows.1)  The impact point and swing direction were mainly controlled not by a change in arm swing motion, but by a change in upper body posture.2)  To generate ball spin, it is necessary to avoid a head-on collision between the ball and the racquet (a normal vector of the racquet face is parallel to the racquet face velocity vector). Therefore, players decreased the amount of upper trunk leftward rotation in kick and slice serves at the point of impact so as to swing the racquet more laterally.3)  It is necessary to swing the racquet more vertically in order to lean the rotation axis of the ball. Therefore, players controlled the upper trunk leftward-rightward and forward-backward leaning in a kick serve at the point of impact.4)  Changes in upper body posture cause changes in the direction the racquet faces. Therefore, players mainly controlled their elbow pronation-supination angle in order to maintain a racquet face direction that satisfies a legal serve.

本研究では,レジスタンス運動における代表的な負荷方法であるStrength-up type(S-type)の運動とBulk-up type(B-type)の運動と負荷特性の相違を,動作中の筋放電量(実験A)と運動後の成長ホルモンの分泌量(実験B)の両面から検討することを目的とした。実験A,Bともに,被験者には健常な一般成人男性8名を用い,S-typeの運動とB-typeの運動をそれぞれ異なる日に行わせた。運動には,実験Aでは片脚による膝伸展運動を,実験Bでは両脚による膝伸展運動を用いた。実験A,Bともに,S-typeの運動においては1RMの90%の負荷を,セット間に3分間の休息をはさんで5セット行わせた。これに対して,B-typeの運動においては,1-3セットは1RMの80,60,40%,4-6セットは70,50,40%,7-9セットの間には30秒間,3-4,6-7セットの間には3分間の休息をはさんで,合計9セット行わせた。両運動ともに,いずれのセットにおいても動作は可能な限り反復させた。主な結果は以下の通りである。(1)各セットにおける反復回数は,S-typeの運動では3-8回の範囲にあったが,B-typeの運動では8-24回の範囲にあった(実験A,実験B)。(2)各セットにおける大腿直筋,外側広筋,内側広筋の%mEMGを平均化した値は,S-typeの運動では等尺性最大筋力発揮時の値とほぼ同様の水準が維持されていたのに対して,B-typeの運動では,3セットごとにみるとセット数が進むにつれてて低下したが,9セット全体でみると徐々に増加する傾向が認められた(実験A)。(3)各セットにおけるFmeam/%mEMGは,s-typeの運動ではいずれのセットにおいても一定の水準が維持されていたのに対して,B-typeの運動ではセット数が進むにつれて大きく低下する傾向が認められた。(4)運動後の血清成長ホルモン濃度は,B-typeの運動がS-typeの運動に比較して著しく上昇し,両運動間には運動後のいずれの時間においても有意差が認められた(実験B)。また,血中乳酸濃度も,B-typeの運動がS-typeの運動に比較して高値を示した(実験A,実験B)。(5)運動後における大腿囲の増加率は,B-typeの運動がS-typeの運動に比較して有意に高値を示した(実験A,実験B)。(6)運動後におけるMVCおよびMRFDの減少率は,いずれもB-typeの運動がS-typeの運動に比較して有意に高値を示した(実験B)。上述の結果は,S-typeの運動とB-typeの運動における負荷特性には,神経系の改善と筋肥大に関連した要因から見てきわめて大きな相違があること,およびこれらの相違が両運動のトレーニング効果の差に影響を及ぼす可能性があることを示唆するものである。

The purpose of this study was to evaluate the multistep drop jump (DJ) test in elite jumpers according to changes in test performance, ground reaction force, and lower limb joint kinetics with changes in drop height. Male jumpers (n=10) performed a DJ from 4 drop heights (0.3, 0.6, 0.9, and 1.2 m). The DJ-index was calculated by dividing the jump height by the contact time. The rate of change of the DJ-index (a/b) was the slope/intercept of the regression line (Y = aX+ b) derived from 4 values of the DJ-index for each subject. Jump motions in the sagittal plane and ground reaction force data were recorded using a high-speed camera and force platform, respectively. The DJ-index was lower at 1.2 m than at other drop heights. The contact time increased along with the drop height. There was no significant difference in jump height between the drop heights. The amount of negative work by 3 lower extremity joints increased with increasing drop height. The jump events performance (IAAF Score) and DJ-index at each drop height only showed a significant correlation at 1.2 m. The correlation between IAAF score and a/b was significant between these variables. According to individual characteristics, increased drop heights were associated with different patterns of change in the DJ index. Therefore, subjects were grouped according to characteristics using a/b as an index. Sub.A, who had the highest jump-event performance in the study, had participated in international meetings, and had won a medal at the World Junior Championships. The DJ-index for this subject at 0.3 m was close to the mean value, but at 1.2 m was highest among all the subjects. In contrast, the DJ-index for Sub.C at 0.3 m was highest among the subjects. However, the DJ-index decreased greatly with an increase from 0.3 m to 1.2 m. Therefore, to evaluate the performance of jumpers, it is important to use a varied range of heights, including a higher drop height (approximately 1.2 m), focusing on the rate of change with increasing drop height.

Step parameters are associated with running economy (RE), but the relationship between these longitudinal changes remains unclear. In the present study, we aimed to clarify the relationship between changes in step parameters and RE at intensities below and above the lactate threshold (LT) in well-trained middle to long-distance runners and to acquire knowledge applicable to coaching. A total of 29 male university students training in distance running (age, 19.4 ± 1.0 yr; height, 171.3 ± 4.5 cm; body weight, 57.1 ± 3.6 kg) participated in the study. Participants performed multistage incremental treadmill tests to measure step parameters (ground contact time: CT; step length: SL; step frequency: SF; leg stiffness: kleg) and RE before and after 4 months of training. Since the LT speed of participants was 16.6 ± 1.1 km・h−1, intensities below, near, and above the LT were set at 13.8 and 15.0 km・h−1, 16.2 km・h−1, and 17.4 and 18.6 km・h−1, respectively. No significant relationships were observed between changes in RE and any of the step parameters at intensities below and near the LT. Moreover, although no significant relationship was noted between changes in RE and both SL and SF, there was a significant positive and negative relationship between changes in RE and CT and kleg, respectively, at intensities above the LT. Changes in kleg showed a strong negative correlation with CT changes at each intensity. It can be concluded from these findings that shortening the CT improves the RE for high-intensity running and that this variation is partly attributable to the improvement in kleg.

This study aimed to clarify the importance of strength and jump ability of both the kicking and supporting legs for increasing the speed of a soccer ball during instep kicks at various approach speeds. Twelve male university soccer players performed instep kicks using different approach lengths (1 m, 3 m, 7 m, and free length). Maximal isokinetic and concentric muscular strength was measured in terms of knee extension/flexion, hip extension/flexion, and hip abduction/adduction using an isokinetic dynamometer. Jump ability was measured using countermovement jump, double-leg rebound jump, and single-leg rebound jump with the kicking leg and supporting leg. For the instep kick, kinematic and kinetic data were recorded using the Vicon T20 system (250 Hz) and force platforms (1000 Hz). The results of the analyses were as follows:   1.  The approach speed increased as the approach length increased. Moreover, the time between the moment when the foot touched the ground and the moment of ball impact became shortened, and the ground reaction force at all axes increased as the approach speed increased.   2.  Foot speed under all the approach conditions was correlated with hip extension and the abduction strength of the supporting leg.   3.  Foot speed for the 3 m, 7 m, and free-length conditions was correlated with the rebound jump ability of the supporting leg. Moreover, foot speeds for the 3 m, 7 m, and free-length conditions was correlated with hip adduction strength of the supporting leg.   4.  Similar results were obtained for relative foot speed (calculated by dividing foot speed by the speed of the body's center of gravity at the moment of ball impact).   5.  The rate of change in the relative foot velocity (for an approach of 1 m to 7 m) was correlated with the rebound jump ability of the supporting leg.   These results suggest that it is important to improve hip extension and the abduction strength of the supporting leg in order to increase the ball speed, regardless of the approach speed. In addition, it is important to improve the hip adduction strength, especially the rebound jump ability of the supporting leg in order to increase the ball speed when a high approach speed is employed.

The purpose of this study is to confirm aspects of violence at school athletics clubs related to the use of corporal punishment, and to clarify the significance of corporal punishment in terms of how it is perceived by teachers and students.  Recently, there has been a large volume of research on corporal punishment, under the premise that its use is questionable. Such a premise tends to encourage reasons for denying it occurs, or turning a blind eye to how it affects relationships between teachers and students at school athletics clubs. However, in order to clarify the significance of corporal punishment in school athletics clubs, it is essential to understand interpersonal relationships in this type of setting.  The ethos of school athletics clubs is to impose the desirable norm on students (i.e., to make them good players). This means that students need to develop self-discipline in order to succeed at their sport, and corporal punishment is used to impose normalization of self-discipline in students. This leads to an association between pain and the perceived pleasure of success in the mind of the students. According to Butler, conscience is the means by which a subject can reflecting on oneself, and conversion of pain into the pleasure is a method by which this can be achieved. In other words, a panacea for preempting existential negation.  On the other hand, for teachers, corporal punishment is deeply related to their existence and desire for self-protection. Adorno and Horkheimer's arguments on the reasons for the relation between reason and violence in Dialectic of Enlightenment: Philosophical Fragments teach us that the desire for self-protection is expressed by using violence, for example corporal punishments, on others. Teachers regard students as a means for their self-protection to secure their role as a teacher, which is based on a pre-existing relationship with students. However, the role of teachers is threatened when a school athletics club achieves poor results. Thus, teachers employ corporal punishment as a means of maintaining their authoritative role.  The findings of this study argue that corporal punishment in school athletics clubs deeply reflects the relationship between students and teachers. It is necessary to discuss this issue rather than ignoring it.

The purpose of this study was to investigate motion factors in female javelin throwers during success and failure trials from a biomechanical standpoint. Fourteen throwers who participated in the Japanese Women’s Javelin Championships Final were investigated during both success trials and failure trials and the results were compared. The success trial was set as the best record and the failure trial as the worst record. Timing points of throwing motion were set at right foot contact (R-on), left foot contact (L-on) and javelin release (REL). The main results were as follows; 1) There was no significant difference in approach velocity between the success and failure trials. 2) In the success trials, peak speeds of the right shoulder, elbow joint and javelin were higher than those in the failure trials. 3) In the success trials, the left rotation velocity of the shoulder angle was larger than that in the failure trials just after L-on. 4) In the success trials, the forward rotational velocity of the trunk was larger than that in the failure trials just after L-on. 5) In the success trials, the throwers maintained a more extended position of the left knee angle than in the failure trials between L-on and REL. These results revealed that superiority or inferiority for female javelin throwers at the same competition level was determined not by the approach velocity, but by the blocking motion of the left leg. Although the importance of this left leg blocking motion has been reported many times in previous studies of throwers with different performance levels, it has been shown here to play an important role in the success of individual performance.

The aim of the present study was to investigate the effect of experience or inexperience with weight-training under appropriate supervision on knowledge of squatting exercises among university students. A questionnaire-based survey was conducted among university students who exercised regularly (30 or more min per day, 2 or more days per week, and maintaining this for more than 1 year) to clarify the relationships between their experience of weight-training under appropriate supervision, knowledge of squatting exercises, and the frequency with which they perform squatting exercises (n=309). More than half of the students who exercised regularly had never experienced weight-training under appropriate supervision. Approximately 50% of the participants performed squats periodically, even if they did not have any experience with weight-training under appropriate supervision. The participants who lacked experience with weight-training under supervision had made significantly fewer attempts to consciously train their gluteal and knee flexor muscles during squatting exercises than those who had experienced weight-training under supervision. In fact, approximately 50% of the former did not consciously train their gluteal muscles during squatting exercises at all. These results suggest that although the students performed squatting exercises periodically, those who had never experienced weight-training under supervision may not have properly understood the squatting method. Therefore, to enhance the benefits of training, people should be shown the correct method for performing training exercises and given appropriate supervision.

The aim of the present study was to investigate the differences in kinematics between 2 types of motor strategy for expert dart throwing. We divided 8 experts into 2 groups based on the motor strategies they had demonstrated in a previous study (Nasu et al., 2014): group A were experts who had a longer time window in which a release could result in hitting the bull's eye, and group B were experts who had a shorter time window but greatly reduced their timing error. Each subject performed 60 dart throws, aiming at the center of the dart board (bull's eye). The movement of the dart, index finger, and joint motion of the upper extremity were captured using a motion capture system with 7 cameras (480 Hz, Oqus300, Qualysis Inc.). We compared the shape of the hand trajectory and joint kinematics between the groups. We found that experts in group A demonstrated a smaller shoulder angle (lower elbow height) and a larger angle of elbow flexion through forward swing than those in group B. These differences affected the time window that led to a successful throw, i.e. the time for which the mutually complementary relationship among the release parameters (especially the relationship between velocity and direction of motion) was maintained. These results may be useful as basic data to help clarify how throwing accuracy can be improved in several sports.

The present study was verify of reliability and validity the regression equation constructed using the game footage from the 2010 FIFA World Cup. Formulated using multivariate logistic regression analysis, this equation’s purpose was to predict the probability of a goalkeeper’s failure to stop shots at goal. The 2014 dataset consisted of 587 shots at goal from within the frames during 64 games played by 32 teams that participated in the FIFA World Cup in Brazil. The results showed that for the probability of failing to block a shot predicted by the regression equation, the two inter-rater interclass correlation coefficient was high (0.91), thus demonstrating reliability. Furthermore, when a contingency table was created with a cut-off value of 0.5, accuracy was high (85.9%); when an ROC curve was drawn and the area below the curve was measured (0.874), it was notably distinct, indicating generalizability. Therefore, the regression equation predicting the probability of failure to block a shot has high generalizability for predicting world-class goalkeepers’ probability of failure to block shots. This is considered a useful formula for evaluating goalkeepers’ blocking ability.

The purpose of this paper is to extend understanding of Richard Shusterman’s somaesthetics to Education. In order to do so, John Dewey’s pragmatism will be placed in between somaesthetics and Education. Dewey played an essential part in the development of somaesthetics――not only its genealogy but also its fundamental concepts, for instance, “body”, “practice”, and “body consciousness”. Examining Shusterman’s understanding of Dewey’s pragmatism will help to clarify the pragmatic aspects of somaesthetics. To examine the possibility of extended understanding of somaesthetics for Education, the philosophy of physical education will be considered. Somaesthetics provides pragmatic viewpoints on the philosophy of physical education. From this viewpoint, the philosophy of physical education shauld be based on live somatic experience rather than on foundationalism.

The purpose of this study was to analyze the responses of foreign countries on the cancellation of the Games of the XII th Olympiad, Tokyo, 1940, and to clarify the principles underlying the arguments for and against the cancellation. The documents used for this study centered around the correspondence between Ministry of Foreign Affairs and Japanese governmental establishments abroad and the stored archives as to the Games of the Diplomatic Record Office of the Japan Ministry of Foreign Affairs. The findings of this study are summarized as follows : After the outbreak of Janpan-China War in 1937, there were many opinions against the hosting the Games of the XII th Olympiad by the city of Tokyo as well as the participation in it which were expressed mainly by European countries and U.S.A., together with those for expressed by U.S.A. and Brazil. Olympism seemed to be the basic and standard thought for these opinions, and it was interpreted into two ways so that opinions were divided and varied. Some of the experts took the position that Olympism should be the means and occasion for "realizing the peace of the world", and others took it should be "independent from politics". Thus, such a pre-war problem of boycotting as the Games of the XII th Olympiad in Tokyo appears to entail the similar post-war pattern of thoughts and interpretations in repeated boycott cases of the Olympic Games.

The purpose of this study was to clarify the function of torques exerted by the joints of the lower trunk during maximal velocity sprinting. Eight male track and field athletes volunteered, and sprinted 60 m from a standing start position. The ground reaction force of the support leg was determined using a force platform (1000 Hz), which was placed at the 50-m mark from the start position. Simultaneously, 3D coordinates were recorded with a motion analysis system (250 Hz) using 20 cameras (MX-T20). The joint torques were calculated using inverse dynamics. The contribution of joint torques to the right and left hip joint forces, and the torso joint force, was calculated by a method that simultaneously solves equations of motion for each segment and equations of constraint conditions for adjacent segments connected by a joint. The main results were as follows: (1) During the terminal support phase (80-100% normalized time), the angular velocity of anterior rotation of the pelvis decreased and participants in whom this angular velocity decrease was diminished ran faster (p<0.10). (2) During terminal support, the hip joint adduction torque of the support leg and the anterior rotation torque of the torso joint rotated the pelvis forward. The moment of the right and left hip joint forces rotated the pelvis backward. (3) During terminal support, the hip joint force of the support leg was generated by its hip joint flexion and adduction torque, the hip joint extension torque of the recovery leg, and the anterior rotation torque of the torso joint. In contrast, the hip joint force of the recovery leg was generated by the hip joint flexion and adduction torque of the support leg, and the anterior rotation torque of the torso joint. (4) During terminal support, the hip joint flexion torque exerted by the support leg rotated the pelvis backward. The hip joint adduction torque of the support leg and the anterior rotation torque of the torso joint rotated the pelvis forward. Previous studies showed that the hip flexion torque drives the leg forward from the hip joint extension position. This present study has clarified that the hip joint adduction torque of the support leg and the anterior rotation torque of the torso joint nullify backward rotation of the pelvis due to the hip joint flexion torque exerted by the support leg.
