研究非特异性腰痛（non-specific low back pain,NLBP）患者的腰骶结构特征及其影响因素。方法：招募筛选NLBP患者71例（NLBP组）及29例无腰痛的健康人群（Con组）。填写问卷评估疼痛程度和腰功能障碍,并分别拍摄矢状面及额状面的X光片,测定腰椎前凸程度和骨盆侧倾程度的相关指标。研究发现：①NLBP组腰椎前凸程度与Con组相比无显著性差异（P>0.05）;②NLBP组与Con组相比骨盆发生明显侧倾（P<0.05）;③性别对NLBP患者腰骶结构没有影响;④不同年龄的NLBP患者腰椎结构有发生不同的改变,青年患者与中老年患者相比,腰骶出现了显著的腰曲变直（P<0.05）及骨盆侧倾（P<0.01）;⑤症状也会影响NLBP患者的腰椎前凸程度（P<0.05）。研究结论：①骨盆侧倾是NLBP患者的共性,可将该指标用于临床诊断和疗效评估;②不同年龄、性别和症状的NLBP患者进行康复时应有针对性。 相似文献
Background: Within the context of sports coaching and coach education, formalised mentoring relationships are often depicted as a mentor–mentee dyad. Thus, mentoring within sports coaching is typically conceptualised as a one-dimensional relationship, where the mentor is seen as the powerful member of the dyad, with greater age and/or experience [Colley, H. (2003). Mentoring for Social Inclusion. London: Routledge].
Aim: The aim of this study was to explore the concept of a multiple mentor system in an attempt to advance our theoretical and empirical understanding of sports coach mentoring. In doing so, this paper builds upon the suggestion of Jones, Harris, and Miles [(2009). “Mentoring in Sports Coaching: A Review of the Literature.” Physical Education and Sport Pedagogy 14 (3): 267–284] who highlight the importance of generating empirical research to explore current mentoring approaches in sport, which in turn can inform meaningful formal coach education enhancement. The significance of this work therefore lies in opening up both a practical and a theoretical space for dialogue within sports coach education in order to challenge the traditional dyadic conceptualisation of mentoring and move towards an understanding of ‘mentoring in practice’.
Method: Drawing upon Kram’s [(1985). Mentoring at Work: Developmental Relationships in Organisational Life. Glenview, IL: Scott Foresman] foundational mentoring theory to underpin a multiple mentoring support system, 15 elite coach mentors across a range of sports were interviewed in an attempt to explore their mentoring experiences. Subsequently, an inductive thematic analysis endeavoured to further investigate the realities and practicalities of employing a multiple mentoring system in the context of elite coach development.
Results: The participants advocated support for the utilisation of a multiple mentor system to address some of the inherent problems and complexities within elite sports coaching mentoring. Specifically, the results suggested that mentees sourced different mentors for specific knowledge acquisition, skills and attributes. For example, within a multiple mentor approach, mentors recommended that mentees use a variety of mentors, including cross-sports and non-sport mentors.
Conclusion: Tentative recommendations for the future employment of a multiple mentoring framework were considered, with particular reference to cross-sports or non-sport mentoring experiences. 相似文献
The aim of this cross-sectional study was to compare bone mass in young female athletes playing ball games on different types of playing surfaces. About 120 girls, 9–13 years of age (10.6 ± 1.5 years old Tanner I–III) were recruited and divided into prepubertal and pubertal groups. The sample represented 3 groups of athletes: soccer (N = 40), basketball (N = 40), and handball (N = 40); and 6 different playing surfaces (soccer – ground, soccer – artificial turf, basketball – synthetic, basketball – parquet, handball – synthetic, and handball – smooth concrete). Total and regional body composition (bone mass, fat mass, and lean mass) were measured by dual-energy X-ray absorptiometry (DXA). The mechanical properties of the surfaces (force reduction, vertical deformation, and energy return) were measured with the Advanced Artificial Athlete (Triple A) method. The degree of sexual development was determined using Tanner test. The pubertal group showed that soccer players on the ground, basketball players on synthetic, and handball players on smooth concrete had higher values of bone mineral content (BMC) and bone mineral density (BMD) (P < 0.05) than the soccer players on the artificial turf, basketball players on parquet, and handball players on synthetic. In conclusion, a hard playing surface, with less vertical deformation and force reduction, and greater energy return, is associated with higher levels of BMD and BMC in growing girls, regardless of the sport they practice. 相似文献
Sports gambling is a well-established practice in Israel, whose beginnings can be traced to 1951. In recent years, the activities of the Israel Sports Betting Board (ISBB), also known as the ‘Toto Commission’, have become extremely popular with the public at large, and especially with sports fans. The study examines the changing advertising messages and creative appeals featured in the ISBB’s various advertising campaigns throughout Israeli history, and specifically the broad social meanings that can be inferred from these campaigns. The findings illustrate how significant structures of meaning in advertising function as reflections of the state of sports and society in Israel and as representations of some of the most salient phenomena in these domains. For example, for many years advertisements have been dominated by male presence, reflected primarily in the featured characters and language representations. Also prominent are representations of militarism as well as global biases, which are illustrated by the use of English in the local Israeli gambling brand name (‘Winner’), for example. 相似文献

AbstractThe paper draws attention to free time activities in the Polish countryside after 1945. In pre-war rural worldview, every action in which the element of household usefulness was absent, was valued negatively, and considered to be laziness. Growing spatial mobility of village dwellers and changing attitudes towards work on farms resulted in depreciation of land as superior value. This shift together with industrialization and positive valuation of urban culture brought new patterns of spending time in the countryside. Traditionally, ‘Neighbourhood sit-ins’ – a kind of zone of pleasure and fun, situated on the border between the spheres of work and active rest – have been transformed into something totally different. The emergence of radios, TV sets, and pop culture meant that group meetings were focused on content entirely separate from work. In my article, I would like to examine the intersection of two domains of leisure in post-war countryside, time of community, associated with relaxing meeting, spontaneous fun on the one hand and organized time of the youth on the other. Another major issue I would like to discuss in my paper is emergence of private spare time and its perception by village dwellers. 相似文献
