An anthropometric analysis of elite Australian track cyclists 总被引:3,自引:0,他引:3
An anthropometric analysis was conducted on 35 elite male Australian track cyclists having a mean age of 22.6 years and who had been competing on average for 9 years. The relationship of anthropometric parameters to both bicycle saddle height and cycling performance was also investigated. Subjects were allocated, for purposes of comparison, to an endurance or sprint group on the basis of their competitive event. The group members in total were ectomorphic mesomorphs of height 178 +/- 4.8 cm and weight 72.5 +/- 6.6 kg on average. Percentage of saddle height to lower limb length averaged 99 +/- 1.6%, and significant correlations existed between strength and both body mass (r = 0.57) and thigh girth (r = 0.55). No significant correlation was seen between any anthropometric parameter and performance in an individual event. Cyclists in the spint group were heavier (76.2 +/- 7.4 vs. 70.0 +/- 4.7 kg, P less than 0.01) and stronger (258 +/- 44.4 vs. 216 +/- 30.5 Nm, P less than 0.01), and had larger chest (98.2 +/- 6.2 vs. 92.4 +/- 2.9 cm, P less than 0.01), arm (33.0 +/- 2.2 vs. 30.7 +/- 1.6 cm, P less than 0.01), thigh (57.5 +/- 3.4 vs. 54.3 +/- 2.5 cm, P less than 0.01) and calf girths (37.8 +/- 1.7 vs. 36.2 +/- 1.9 cm, P less than 0.05) than cyclists in the endurance group. They were also more mesomorphic (5.3 +/- 0.7 vs. 4.7 +/- 0.8, P less than 0.05) and less ectomorphic (2.3 +/- 0.9 vs. 2.9 +/- 0.6, P less than 0.05) than the endurance cyclists. 相似文献

Itinerant booksellers play very significant but less noticeable role in the book trade in Ghana and many developing economies. They are the mobile booksellers who carry their collections to the doorsteps of their consumers. This paper highlights the contributions of itinerant booksellers to book distribution in Ghana. The paper makes a case for and against itinerant bookselling in Ghana. First, the paper raises issues with the quality and content of some of the reading materials peddled by the itinerant booksellers and discusses their implications for copyright and book development. The paper then argues that in spite of their shortcomings, itinerant booksellers have the potential to assist in finding a lasting solution to the book distribution problems of the country, and, need to be encouraged and assisted by book industry players such as the Ghana Development Council, Ghana Book Publishers Association, and the Ghana Booksellers Association to contribute meaningfully to Ghana??s book business. 相似文献

In May 2002, the Denison Memorial Library at the University of Colorado Health Sciences Center and the J. Otto Lottes Health Sciences Library at the University of Missouri-Columbia, with funding from the National Network of Libraries of Medicine-Midcontinental Region, embarked on a collaborative, real-time reference project using the 24/7 Reference, Inc., software package. This paper describes how the project was conceived, and includes details on the service hours, staffing, training, marketing, lessons learned, and future plans for the service. 相似文献

Historical research benefits students of publishing in three ways. First, it provides an accurate account of what happened
in the past. Second, by setting contemporary issues in a historical context, it helps identify trends. Finally, it encourages
curiosity and learning about one’s cultural and intellectual heritage. Parker provides examples of research that serve these
purposes.

Framed within intersectionality, this multiple case study explores women's participation in physics through the construct of physics identity and with a focus on recognition. The study is drawn upon an empirical life-history exploration of three women: a native to Northwestern Europe, late-career white woman and two immigrant women to Northwestern Europe, one is an undergraduate student of color, and the other, an early career Muslim woman. The data for this study were collected through multiple, semistructured, interviews in a period of 2 years, which were analyzed using a constant comparative method. Collectively, the three life-histories tell stories of otherness, persistence, hope, and failure and they elucidate the kinds of identities that are deemed “in-place” and “out-of-place” in physics. They showcase how the three women authored multiple identities that simply co-existed for them, while for others were seen as conflicting and caused misrecognition. The findings point to four main insights: (a) recognition is neither linear nor binary and it comes in many different forms that range from explicit encouragement to no opposition; (b) it is drawn upon various sources including ones in the early years of life: family, school teachers, university instructor, students, and social community; (c) it is culture-dependent and as such, it is influenced by factors on multiple levels, including cultural and gender stereotypes, organizational policies, racism, sexism, classicism, and other forms of discrimination. The implications of these findings speak to the need for: (a) systemic programs on how women are recognized by others and which seek to widen and diversify physics environments from the school level to the professional level; (b) research exploration of the politics of recognition and how they perpetuate the underrepresentation of women in physics; and, (c) disrupting monolithic theorizations of recognition and adopting intersectional approaches to exploring physics identity that value women's personal histories, subjectivities, and positionalities. 相似文献
