In our survey, semi-structured interviews were conducted between February and June 2020 targeting five health and physical education teachers working at junior high school and high school. The obtained data were analyzed by the qualitative descriptive method. As a result, we found that the specialized teachers selected as the subjects in this study “Help students understand the contents of sexuality education”, “Comprehensively cover topics on sexuality”, “Offer individual support to students who need extra assistance”, “Cooperate closely with colleagues and guardians”, and “Understand diversity in sexuality”. It was suggested that in order to improve and enrich the programs of future sexuality education, teachers are further required to (1) Devise teaching materials and methods used in classes from the perspective of encouraging students to think, (2) Comprehensively cover topics on sexuality related to modern issues while taking human rights into account, and (3) Cultivate diversity regarding sexuality. It was also suggested that teachers should continuously try to grasp the learning situation of each student while offering thoughtful support as they consult and share information with colleagues and guardians in the practice of sexuality education.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126958667","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 pelvic inclination and the lumbar angle were 4 calculated. Surface electrodes were attached to the rectus abdominis, external oblique, 5 internal oblique, multifidus, erector spinae, latissimus dorsi, rectus femoris, and biceps 6 femoris. Three consecutive strokes at the 20% and 80% time-points of a 2000 m race 7 simulation were analyzed. The root-mean-square was calculated during the early drive 8 phase, late drive phase, and recovery phase. Root-mean-square amplitude was 9 normalized by maximum voluntary contraction. Between two time-points, paired t-tests 10 for each angle and Wilcoxon signed-rank tests for each muscle were performed. 11 Biceps femoris activity during the late drive phase and rectus abdominis activity during 12 the recovery phase decreased significantly in prolonged rowing. Posterior inclination of 13 the pelvis at the catch and middle positions, lumbar flexion at the catch position, and 14 activity of the erector spinae and multifidus during the early drive phase increased 15 significantly in prolonged rowing. The inability to maintain the set position during the 16 recovery phase owing to decreased rectus abdominis activity may lead to excessive 17 posterior pelvic tilt in the catch position. Since an increase in the posterior inclination 18 of the pelvis and lumbar flexion occurred in apparent opposition to erector spinae and 19 multifidus function, repetitive rowing may have decreased the control of the 20 intersegmental motion of the lumbar spine.","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128088251","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}

Twenty aerobically 3 trained participants had a panoramic ultrasound taken of their rectus femoris and vastus lateralis 4 muscles on their right leg before performing a maximal aerobic cycling test.

The purpose of this study was to determine the response of FABP4 to incremental maximal exercise in exercise-trained and untrained men. Eleven exercise-trained young men (T group; age, 20.4 ± 1.2 years) and 9 untrained young men (UT group; age, 20.7 ± 0.5 years) performed an incremental maximal exercise after a 12-h fasting period. Before and immediately after the incremental maximal exercise, venous blood was drawn to measure circulating FABP4, free fatty acid, and glycerol concentrations. Body composition, and aerobic capacity were also assessed. Glycerol concentration significantly increased during the exercise in the T group (group × time interaction: p = 0.034; group effect, p = 0.088; and time effect, p = 0.003), and the percentage increase in glycerol concentration was greater in the T group than in the UT group ( p = 0.046; ES( r ): 0.45). Although circulating FABP4 concentration significantly increased in the two groups (group × time interaction: p = 0.766; group effect, p = 0.114; and time effect, p = 0.001), the percentage increase in FABP4 concentration was similar ( p = 0.210; ES( r ): 0.28). Additionally, the change of FABP4 concentration was not correlated with that of glycerol (r = -0.04, p =0.872). These results indicated that circulating FABP4 concentration increased during incremental maximal exercise regardless of difference in lipolysis and exercise training status in healthy young men. circulating FABP4 concentration to an incremental maximal exercise in exercise-trained and untrained men. Our data demonstrated that despite that exercise-trained men had a greater lipolysis during the incremental maximal exercise, circulating FABP4 concentration increased similarly during this exercise in both exercise-trained and untrained men. Moreover, the change in circulating FABP4 concentration during the incremental maximal exercise was not correlated with that of FFA and glycerol. These findings suggest that circulating FABP4 concentration increases during high-intensity acute exercise regardless of the exercise training status, and the increase in circulating FABP4 concentration during high-intensity acute exercise is accompanied by the increases in blood level of glycerol in the trained but not in the untrained men. that circulating FABP4 during acute incremental maximal exercise in both exercise-trained and untrained an increase in circulating FABP4 concentration was observed in all participants. Thus, high- intensity acute exercise is more likely to increase circulating FABP4 concentration in healthy young individuals. Our findings provide further evidence of the response of circulating FABP4 men. This suggests that suppression of macrophage functions leads to attenuation of the secretion of FABP4 from macrophages in exercise-trained men. However, lack of the data specified for macrophages do not allow us a deeper discussion regar","PeriodicalId":341890,"journal":{"name":"International Journal of Sport and Health Science","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114084809","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}
