This study enrolled 137 male players from a Japanese collegiate 3 rugby union club during the 2009–2013 seasons. Twenty-nine (53.7%) of 54 incidents leading 4 to mild cervical injury were identified from match video records and injury data that were 5 reported under the definition of medical attention. In addition, all tackles by players in the same 6 match in which they sustained cervical injury were extracted as a control cohort. All tackles 7 were coded according to eleven characteristics of three tackle phases. Twenty-one tackles were 8 the main events leading to mild cervical injury. The likelihood of tackler-associated mild 9 cervical injuries was significantly higher when tacklers had no time to face forward at the 10 offside line before tackle situations, tackles with incorrect tackler head positions, and not using 11 arms after initial contact. These results suggest that further investigation is needed to determine 12 specific tackling characteristics considering the three tackle phases and their combined effects. 13 16 17 18 19 20 21 22 23 24 25","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116024118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The kinematics were measured for successful kicking pullovers performed by 12 adult males. Using a 12-segment rigid body link model, the contributions of each body parts to the vertical and angular momentums, the kinematics of both leg joints, and the accelerations of the body parts relative to hip joint of the support leg during the takeoff phase were calculated. The swing leg accelerated away from the ground during the takeoff phase, and was responsible for 64% of the vertical momentum and 43% of the angular momentum of the whole body at takeoff. The hip joint of the support leg extended to the limit of the range of motion at takeoff, achieving both an increase in ground contact time and a backward rotation of the trunk. We concluded that the swing leg greatly contributes to the acquirement of vertical and angular momentum of the whole body in one-leg swing type takeoffs including backward rotation. Specifically, swinging the swing leg using a large range of motion and fully extending the hip joint of the support leg hip joint are the two important technical elements to pre-tense the support leg muscles and increase the ground reaction impulse.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131274548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was designed to prospective examine the association of Hardiness and Social Support with PTG following athletic injuries. University student-athletes ( N = 235) completed a baseline survey that included questions about socio-demographics, and the Japanese version of the Hardiness Scale for University Student at Time 1 (T1). The same athletes completed a second survey (T2) that included questions about experiences of sports-related injuries, the assessment of Subjective Units of Distress (SUDs), and responding to the Japanese version of the Social Support Scales for University Students, 14 months after T1. Four months later (T3), 209 of the same athletes completed the PTG Scale After an Athletic Injury (PTGS-AI). Data of 92 participants that met the screening criteria were analyzed using multiple regression analysis. The results indicated that appraisal support was the only factor that significantly predicted PTG ( β = .48, p < .01) after adjusting for potential covariates such as age and gender. Moreover, hierarchical regression analysis indicated that the association of hardiness and appraisal support with PTG was different for different PTG subscales.

The participants were shown a picture of bent-knee sit-up (sit-up), back extension (back-EXT), and plank from elbows to toes (plank), and were asked which body part(s) they felt was being trained in each picture. As for the frequency of performing these exercises, only 3 z and 8 z of all the participants had never performed sit-up and plank exercises, respectively. On seeing the picture, 40-60 z of the participants who had no experience doing a sit-up or back-EXT felt that these exercises were to train not only the agonist muscle but also the antagonist muscle. Approximately 40 z of the participants who had no experience doing a plank exercise felt that it was not to train the epigastrium or hypogastrium area. Among the participants who experienced doing a plank exercise without a previous experience of strength training under professional supervision, more than half felt that plank exercise was appropriate to train not only the trunk but also the upper limb or lower leg. Further-more, among the participants who had a previous experience of strength training under professional supervision, approximately 30 z had such an opinion. Therefore, although the penetration rate of these trunk exercises are high, doing trunk exercises by referring to only a picture may result in the participants not properly understanding how the body part(s) should be trained during the exercise. Therefore, to enhance the beneˆts of trunk exercises, individuals (even those who had a previous experience of training under professional supervision) always need to be instructed through appropriate supervision on the correct technique and knowledge about the exercises.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116713782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, the paper analyzed Fuchu Sports, a YMA-published newsletter that specialized in sports and was modeled on the popular sports magazine Asahi Sports. The publication of Fuchu Sport was an indication of the strong interest in sports during the Taisho era (1912-1926). After the Ministry of Internal AŠairs and the Ministry of Education announced their directives promoting physical exercise, the Tokyo government hosted conferences on the development of sports and physical education in Tokyo YMA. Accordingly, Tokyo was a step ahead of other regions in Japan when it came to setting up YMA athletic clubs. The founding of the Fuchu YMA Athletic Clubs was mainly supported by the Fuchu YMA, but it also received funding from the local authorities and schools of Fuchu. When the Athletic Club recruited university students to become their coaches, the club's programming changed and its level of competitiveness went up signiˆcantly. Finally, the Athletic Club's collaborations with surrounding educational institutions, particularly school athletic clubs, led to remarkable successes in competition and expanded the club's philosophical mission.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134358851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
