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

不同运动方式对更年期女性身心健康的影响     

陈金鳌  白亚兵  金奕  张林 《北京体育大学学报》2017,40(2):62-67

摘要：目的：探讨不同的运动方式干预对更年期女性体内激素水平、自由基代谢和心理健康的影响效应，旨在为改善和提高更年期女性的生活质量提供参考。方法：随机选取符合纳入标准的更年期女性受试者，依据不同运动方式分为4组，即对照组(CG)24人、有氧运动组(AG)27人、抗阻运动组(RG)27人、健身气功组(QG)27人，实施24周的运动干预，在实验前、中、后分别对相关激素和自由基代谢酶水平进行测量和统计分析，并进行更年期症状与心理状态评估。结果：24周后，AG和RG的血清E2、SOD和CAT值增加幅度，FSH、MDA、XOD值以及Kupperman、SAS和SDS评分降低幅度均明显高于QG和CG。结论：24周中等强度的有氧运动和抗阻运动与低强度的健身气功相比，更有助于改善更年期女性体内的雌激素和自由基代谢水平，缓解心理焦虑、抑郁等更年期不适症状。  相似文献

Executive power and scaled-up gender subtexts in Australian entrepreneurial universities     

Jill Blackmore 《Gender and education》2015,27(3):320-337

Deputy Vice Chancellor and Pro Vice Chancellor positions have proliferated in response to the global, corporatised university landscape [Scott, G., S. Bell, H. Coates, and L. Grebennikov. 2010. “Australian Higher Education Leaders in Times of Change: The Role of Pro Vice Chancellor and Deputy Vice Chancellor.” Journal of Higher Education Policy and Management 32 (4): 401–418]. Senior leadership is the sphere where academic and management identities are negotiated and values around the role of the university are decided. This paper examines the changing and gendered nature of the senior leadership setting and its implications for diversity in and of university leadership. The analysis draws from a three-year empirical study funded by the Australian Research Council on leadership in Australian universities. It focuses on executive leaders in three universities – one which is research-intensive, the second, in a regional site, and the third, university of technology. The article argues that the university landscape and its management systems are being restructured in gendered ways. It utilises the notion of organisational gender subtexts to make explicit how gender works through structural and cultural reform.  相似文献   

Exploring the work and learning stories of para‐teachers in a college for further education in England     

Benita McLachlan 《Support for Learning》2014,29(3):230-243

This paper reports findings from a research project which developed and introduced the Enhanced Learning Support Assistant Programme (ELSAP). This was a source of professional development for learning support assistants who were supporting students with additional learning needs in a college for further education in England. The purpose of this paper is to share findings from the project and to report on how learning support assistants experienced their work in inclusive college classrooms. The research project was a mixed methods study with participants drawn from learning support assistants within one college for further education in England. Data was collected throughout the 14‐week intervention. Findings indicate that issues exist around the uniqueness of the vocational curriculum and the implications this has for classroom support. It also shows how conflicting classroom procedures can generate feelings of confusion and how learning support workers often feel lonely in their role with no natural opportunity to mix with others. Furthermore, it indicates how a general lack of knowledge about teaching and learning contribute to them experiencing difficulty when performing their role which feed their views that a college for further education can be a complex and hostile environment to work in.  相似文献

大学语文课中的性别意识教育——以小说《伤逝》的教学为例     

曾艳 《江西教育学院学报》2011,32(5):78-81

性别意识作为人文精神的一个重要因素，直接影响到大学生的自我角色定位．并关涉其恋爱观、人生观和价值观等多个方面。当代大学生受传统观念的影响，在性别意识问题上存在误区。大学语文课作为高校人文素质教育的基础课程，应改变传统无性别教育状态，从多个角度切人性别意识教育。以《伤逝》的教学为例，通过探讨小说中的性别文化内涵及其对大学生性别意识教育的启示．说明大学语文课渗透性别意识教育的可行性和必要性。  相似文献   

江西省学前教育事业发展研究——基于1995-2008年数据

自1995年以来,受国家宏观教育政策等因素影响,江西省学前教育事业发展也经历了起伏。与湘鄂皖三省相比,江西省学前教育事业发展相对平稳,在每万人拥有幼儿园数量、生师比和3-6岁适龄儿童毛入学率几个方面取得了较大进步,但也存在学前教育供给不足、师资力量薄弱、学前教育普及与公平相冲突及教育功能退化等新矛盾和新问题。  相似文献
