The objective of this study was to describe the anthropometric profiles of elite older triathletes participating in the 2009 Ironman Brazil and to compare their somatotype, anthropometric and body composition characteristics with those of elite young triathletes and older non-athletes. The sample consisted of 64 males, divided into three groups: (1) older triathletes (n = 17), (2) young triathletes (n = 24), and (3) older non-athletes (n = 23). Somatotype was analysed according to the Carter and Heath ( 1990 ) method. Body mass index, sum of four skinfolds, percentage body fat, body fat mass, and fat-free mass were also estimated. Older non-athletes had higher endomorphy, sum of four skinfolds, fat percentage, and body fat mass than the athletes. Older athletes who participated in the Ironman and elite young triathletes had higher fat-free mass than older non-athletes. Older triathletes and older non-athletes were considered mainly endomorphic mesomorphs and young triathletes mainly ectomorphic mesomorphs. The findings that characterize the anthropometric profile of athletes in this sports modality could be used as a reference. 相似文献

Forming a science-oriented identity is considered a process underlying both interest and achievement in science education. A questionnaire is developed for describing “identities as learners” and evaluating their science orientedness. The instrument (k = 65) focuses on cognitive aspects. An internal coherence of .88 was found. Five subscales were defined that proved interrelated yet distinguishable. A pilot amongst 40 students from Dutch general secondary education showed that preferring science over non-science subjects and relatively high grades for sciences subjects were strongly correlated to science orientedness of the learner identity (rs = .65; p < .001). The results support the reliability and validity of the questionnaire but also point to the importance of identity as a central concept in studying science education. It is concluded that we made a promising step in constructing an instrument for monitoring the development of cognitive aspects of science-oriented identities during (innovative) science education. 相似文献

Criminal justice is often criticized for lacking theoretical grounding. This article argues that the introductory criminal justice course should be reconceptualized in such a way that permits a critical assessment of theoretical bases underlying crime, law and justice. Doing so would better prepare students to understand key questions in the study of criminal justice and would also help give criminal justice greater credibility as a stand‐alone academic discipline. In addition to presenting the benefits of a theory‐driven introductory course, possible content and pedagogy are described. 相似文献

This study provides a foundation for discussion of major issues facing community colleges in America. The purpose of the study was to ascertain how many community college presidents rank order issues facing their institutions, now and five years hence. Additionally, the study sought to more comprehensively examine recent literature about issues facing community colleges for purposes of comparison with the findings of the study, and for explication of issues identified. The data for analysis were collected from a population survey of all public and private community college presidents listed in the Education Directory of Colleges and Universities, 1981‐1982. Issues used in the survey were identified a priori, from a review of the literature, and were validated using a panel of community college presidents. The major findings were that both public and private community college presidents agree that the top issues facing their institutions five years hence are: financial support for institution, achieving institutional mission, and maintaining enrollments. Other major current issues include faculty and staff relations, planning and administering the budget, governing board relations, administrative team relations, state relations, public and community relations, and program development and evaluation. Additionally, questions were raised in the study regarding “presidential priority rankings of issues,” based upon directions suggested in the literature review about what issues seem most pressing in the decade of the 1980s. 相似文献
