The unit of 7 long jump classes and 8 high jump classes were focused on the rhythm up last three steps in the approach run, and the take-off movement in the first class and the last class were compared kinematically. Subjects in this study were 1, 2 and 3 grade junior high school students, the number of students in the long jump class was 17 and that the high jump class was 22 . To evaluate the take-off movement quantitatively, two analysis items were used. In long jump, takeoff index which is defined as the value of the vertical velocity at take-off divided by the deceleration of the horizontal velocity during take-off movement, and in high jump, velocity conversion rate which is defined as the value of the vertical velocity at take-off divided by the horizontal velocity at the starting point of take-off","PeriodicalId":119114,"journal":{"name":"Japanese Journal of Sport Education Studies","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131527802","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 effectiveness of the coach in leading and managing this relationship is important for producing appropriate outcomes such as physical and psycho-social development as well as competition results. The focus of this paper is on coaching within the performance environment, which includes development and high performance contexts. Firstly, this paper examines the notion of quality coaching; specifically, how we might conceptualise quality coaching. It is argued is that a key understanding of quality coaching is associated with learning. The learners include all actors within the coaching context, including coaches, athletes and support personnel. In the second part of the paper, the multifaceted and serendipitous nature of coach education and development is discussed.","PeriodicalId":119114,"journal":{"name":"Japanese Journal of Sport Education Studies","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124877071","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}
