Abstract

Although it is acknowledged that appropriate breast support during exercise is important, no published literature has assessed breast support usage in a cohort of female marathon runners. This study aimed to identify sport bra use and perceived importance of sports bra use in female marathon runners. Bra satisfaction, incidence of bra related issues and factors that influence the appropriateness of sports bras were also investigated. A 4-part, 30-question survey was administered to 1397 female runners at the 2012 London marathon registration and via an online survey. In total 1285 surveys were completed. Sports bra use and its perceived importance was high, however was lower in moderate compared to vigorous activity, and lower in participants with smaller breasts. Seventy-five per cent of participants reported bra fit issues. The most common issues were chaffing and shoulder straps digging in, with a higher incidence of issues reported by participants with larger breasts. Use of professional bra fitting was low, and perceived knowledge of breast health was poor. Engagement with sports bra use is high although sports bra design could be improved to alleviate bra fit issues experienced by female runners. Educational initiatives are needed to ensure females are informed regarding the importance of breast support and appropriate bra fit during activity.  相似文献   

The effect of boot stiffness on field and laboratory flexural behavior of alpine ski boots     

Nicola Petrone  Giuseppe Marcolin  Fausto A. Panizzolo 《Sports Engineering》2013,16(4):265-280

The aim of this work was to study the effect of boot stiffness on the field and laboratory flexural behavior of alpine ski boots. Ski boots have a direct influence on performance, safety, and comfort of alpine skiers. Despite their technological evolution during a number of years, the parameters used in the evaluation of boot stiffness are not yet standardized and still require a shared engineering approach to achieve common quantitative definitions to be used either in boot classification or in boot selection for the different users. This work reports the boot flexion angles between shell and cuff and between cuff and tibia, collected during slalom tests on three boots with different nominal Flex Index. The laboratory data collected on the same boots under conventional cyclic bending tests are reported and compared with the field data for the development of a new test method more representative of the field behavior. As a result, clear definitions of Flex Index and of boot stiffness are introduced: boot stiffness had a clear effect on both the field and the laboratory flexural behavior of boots.  相似文献   

Characteristics of the start in women's World Cup skeleton

This study characterizes key elements of the start in elite female World Cup skeleton athletes. The top 20 female competitors in three World Cup races were videotaped within a calibrated space to allow the following components of the start to be quantified: (1) acceleration (velocity at 15-m mark, time to 15-m mark), (2) capacity (time to load, total number of steps to load), and (3) load (velocity at 45-m mark). A correlation analysis was used to establish the relationship between the variables of interest and overall start time (15- to 65-m mark). Velocity at the 15-m mark accounted for 86% of the variance in overall start time at St. Moritz and 85% at Sigulda. A stepwise regression analysis revealed that approximately 89% of the variation in start time could be explained by velocity at the 15-m mark, time to load, and velocity at the 45-m mark. Of the variables analysed in this study, rapid acceleration to attain a high velocity at the 15-m mark was the most important component of a fast overall start time. The importance of the time to load and velocity at the 45-m mark vary according to the different track characteristics.  相似文献   

The Nonreciprocating Robot: Effects on Verbal Discourse, Social Play, and Social Referencing at Two Years of Age     

Philip Dunham  Frances Dunham  Simone Tran  Nameera Akhtar 《Child development》1991,62(6):1489-1502

2-year-old children interacted with a robot in a large playroom while their mother sat quietly in the corner. Identical vocalizations from the robot had very different effects on 3 dimensions of the children's behavior when the vocalizations were embedded in reciprocating and nonreciprocating social structures. The reciprocating robot produced (1) more topic-maintaining verbal dialogue, (2) less physical and more linguistically mediated social play, and (3) gender-specific effects on the children's tendency to visually reference their mother during the play session. The data are discussed with reference to the frequently encountered assumption that reciprocal social structures have an impact on children's behavior when the quantity and other qualitative dimensions of social stimulation are held constant, and with reference to the children's attributions about the robot as a social partner.  相似文献

Becoming a guidance counsellor in Ontario: formative influences from counsellors’ perspective     

Daniel Nadon  André Samson  Nicola Gazzola  Anne Thériault 《International Journal for Educational and Vocational Guidance》2016,16(3):363-377

Contrary to guidance counsellors elsewhere in North America who hold a master’s degree, career and guidance counselling services in secondary schools in Ontario are delivered by teachers who have completed additional undergraduate studies. Guidance counsellors are pivotal components of the school as they complete tasks that promote students’ overall development. The aim of this qualitative study was to explore how teachers perceive and describe the process of becoming guidance counsellors in Ontario. The thematic analysis revealed four major themes that articulated the process of becoming a guidance counsellor in Ontario: peer guidance, contextual factors, professional experience, and theoretical knowledge.  相似文献   

Optical versus virtual: teaching assistant perceptions of the use of virtual microscopy in an undergraduate human anatomy course   总被引：1，自引：0，他引：1  

Collier L  Dunham S  Braun MW  O'Loughlin VD 《Anatomical sciences education》2012,5(1):10-19

Many studies that evaluate the introduction of technology in the classroom focus on student performance and student evaluations. This study focuses on instructor evaluation of the introduction of virtual microscopy into an undergraduate anatomy class. Semi-structured interviews were conducted with graduate teaching assistants (TA) and analyzed through qualitative methods. This analysis showed that the teaching assistants found the virtual microscope to be an advantageous change in the classroom. They cite the ease of use of the virtual microscope, access to histology outside of designated laboratory time, and increasing student collaboration in class as the primary advantages. The teaching assistants also discuss principal areas where the use of the virtual microscope can be improved from a pedagogical standpoint, including requiring students to spend more time working on histology in class.  相似文献   

Health Sciences Librarians' Research on Medical Students' Use of Information for Their Studies at The Medical School,University of Queensland,Australia     

Kaye E. Lasserre  Nicola Foxlee  Lisa Kruesi  Julie Walters 《Medical reference services quarterly》2013,32(2):141-157

This study reports the findings of research undertaken by health sciences librarians at the University of Queensland Library into how medical students use information for their studies, particularly resources and services provided by the Library. The methods utilized were an online survey and focus groups. Results indicated that students favor print resources over electronic, value accessing resources on a one-stop basis, and prefer training to be delivered flexibly. The implication of these results for future resource selection, service provision, and instructional design and delivery is discussed.  相似文献   

Using Decision Tree Analysis to Understand Foundation Science Student Performance. Insight Gained at One South African University     

Nicola Frances Kirby  Edith Roslyn Dempster 《International Journal of Science Education》2013,35(17):2825-2847

The Foundation Programme of the Centre for Science Access at the University of KwaZulu-Natal, South Africa provides access to tertiary science studies to educationally disadvantaged students who do not meet formal faculty entrance requirements. The low number of students proceeding from the programme into mainstream is of concern, particularly given the national imperative to increase participation and levels of performance in tertiary-level science. An attempt was made to understand foundation student performance in a campus of this university, with the view to identifying challenges and opportunities for remediation in the curriculum and processes of selection into the programme. A classification and regression tree analysis was used to identify which variables best described student performance. The explanatory variables included biographical and school-history data, performance in selection tests, and socio-economic data pertaining to their year in the programme. The results illustrate the prognostic reliability of the model used to select students, raise concerns about the inefficiency of school performance indicators as a measure of students' academic potential in the Foundation Programme, and highlight the importance of accommodation arrangements and financial support for student success in their access year.  相似文献
