Eight competitive male track and field athletes (22.3 ± 1.0 years) performed a 30-s pedaling test at seven different intensities corresponding to O 2 demands of 40, 50, 60, 70, 80, 90, and 100 ml/kg/min. The power outputs required at each O 2 demand were determined from the extrapolated linear relationships between power and the steady-state O 2 uptake obtained during submaximal-intensity exercise. The V 4 O 2 max test and 30-s Wingate anaerobic test were also performed. Relative aerobic and anaerobic energy contributions were estimated by the ratio of O 2 uptake and O 2 deficit, the latter being calcu lated as the difference between O 2 demand and O 2 uptake. The exercise intensity of the 30-s pedaling test ranged from 73.4 ± 7.4 to 180.9 ± 18.2% V 4 O 2 max. As exercise intensity increased, O 2 uptake (13.9 ± 2.1 to 26.8 ± 2.1 ml/kg/min) and O 2 deficit (26.9 ± 2.1 to 73.7 ± 2.2 ml/kg/min) during the 30-s pedaling test increased (P ˂ 0.05). However, the relative aerobic (34.1 ± 5.1 to 26.7 ± 2.0%) and anaerobic (65.9 ± 5.1 to 73.3 ± 2.0%) energy contributions during the 30-s pedaling test did not differ across all O 2 demands (P ˃ 0.05). These results suggest that the rel ative aerobic and anaerobic energy contributions during short-duration exercise remain nearly constant over a wide range of exercise intensity.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131063467","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}

An internet survey was conducted anonymously using a structured questionnaire, with items regarding the respondent’s basic information, their collaboration with other healthcare professionals, and their experiences with medication support for athletes. Of the 841 pharmacists who completed the survey, 21.4% had experienced anti-doping inquiries from athletes, and 18.7% of non-sports pharmacists had experienced medication consultations with athletes. Significantly more accredited sports pharmacists than non-sports pharmacists referred to the World Anti-Doping Agency’s (WADA) Prohibited List (p = 0.009), the Global Drug Reference Online (Global DRO) (p < 0.001), and the Japan Pharmaceutical Association’s antidoping hotline (p = 0.001). A significantly greater proportion of male pharmacists (p < 0.001), accredited sports pharmacists (p < 0.001), and pharmacists who cooperated with other healthcare professionals, such as medical doctors and dietitians (p < 0.001), reported that they were confident handling anti-doping inquiries. Although pharmacists generally conduct consultations with athletes, further education is needed, as pharmacists have trouble effectively providing information on doping prevention. Ideally, athletes should consult with accredited sports pharmacists who have undergone continued anti-doping education.

It references Erich Fromm’s Authority Theory and invokes Fromm’s opinion on sadism, in particular. As an example of sadistic tendency, Fromm mentions the idea of absolute control over another person to exploit them, create dependency, and use them as a tool. The results of the present study suggest that a harsh work environment involving the instructor of an extracurricular sports club promote the rationalization of sadistic tendencies by the instructor. Fromm points out that sadistic tendency arise from the incapacity to function as an isolated individual and the need to form a symbiotic relationship to overcome isolation. Instructors that exhibit sadistic tendencies inhibit the freedom and independence of their students and attempt to dominate them in order to feel strong. Corporal punishment is an effective means of dominating students. The sadistic tendencies of an instructor in an extracurricular sports club are suggested to arise from the need to form a symbiotic relationship with students in order to overcome 調査・実践報告名桜大学総合研究,(28):127-132(2019) * 名桜大学人間健康学部スポーツ健康学科〒905-8585 沖縄県名護市為又1220-1 Department of Sports and Health Sciences, Faculty of Human Health Sciences, Meio University, 1220-1, Biimata, Nago, Okinawa 905-8585, Japan","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130212179","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}

We administered a questionnaire survey to 871 fifth- and sixth-grade el ementary school students in Japan. We found that the physical competence of elementary school students could be assessed in terms of five factors comprising a total of 19 items: a feeling of control, a feeling of approval, a feeling of omnipotence, a feeling of superiority, and a feeling of progress. Furthermore, we found that Fifth graders had significantly higher scores for a feeling of control than sixth graders did, and boys generally scored better in physical competence than girls did, except feeling of superiority. The physical competence scale developed in this study can be used to better understand elementary school students’ perceptions of their own competences and experiences in physical education classes. The results of this study also indicate that improving physical competence is not always positive. For instance, the ‘‘feeling of superiority’’ should not be encouraged. In other words, high levels of the ‘‘feeling of superiority’’ could cause serious discord in classmate interaction, including the exclusion or isolation from teams of children who are unskilled at exercise. This must be examined more closely in future teaching research.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117014382","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}

Methods: Data were obtained from 45 official matches over the 2013, 2014, and 2015 seasons of one team. Global positioning system units with built-in accelerometers were worn by the players; the per-match total distances, accelerations, and impact forces were calculated for the forwards and backs. Match results consisted of two elements: win-loss result and score differ -ential. Results: Data showed that each parameter had high values in closely fought matches when a team lost or when the point differential was small. In addition, physical performance was im pacted differently from one position to another. Forwards engaged in significantly less high-acceleration and high-impact activity in wins but significantly higher activities in close matches ( p < 0.05). Backs engaged in significantly higher impacts (i.e., harder/more tackles) in close matches ( p < 0.05). Conclusions: Based on these data, some suggestions for new approaches that can be adopted by strength and conditioning coaches to optimize training-related performance and prevent sports injuries have been included.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127246189","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}
