Ethics and paediatric exercise science: Issues and making a submission to a local ethics and research committee     

Russell Jago  Richard Bailey 《Journal of sports sciences》2013,31(7):527-535

Research with children presents issues beyond those normally encountered in adult exercise science research. This paper explores the specific ethical issues that are encountered when conducting paediatric research in the exercise sciences. We identify the historical, moral and philosophical underpinnings of ethical conduct. The issue of consent and children's ability to provide informed consent is discussed, as is the nature of therapeutic and non-therapeutic research. Finally, we examine the information that is required by a local ethics and research committee and provide guidance material to help in the formulation of an application to such a committee.  相似文献   

Parameterising expertise in coaching: Past,present and future     

Christine Nash  Russell Martindale  Dave Collins  Amanda Martindale 《Journal of sports sciences》2013,31(10):985-994

Abstract

Research into expertise is increasing across a number of domains pertinent to sport. Whilst this increase is particularly apparent in coaching, a key question is how to identify an expert coach? Accordingly, this paper draws upon existing studies into expert coaches to address this issue; in particular, the criteria used to select expert coaches for research purposes and the methods used in expert coach research. Based on these data, we contend that the elements of expertise are not fully reflected within currently accepted criteria which, in turn, results in expert coaching research not necessarily identifying the appropriate individuals to study. The paper concludes with recommendations for more rigorous criteria for selecting expert coaches and highlights the associated implications for the future training and development of expert coaches.  相似文献   

Relationships between talent development environments and mental toughness: The role of basic psychological need satisfaction     

Chunxiao Li  Russell Martindale  Yanlin Sun 《Journal of sports sciences》2013,31(18):2057-2065

ABSTRACT

Although the talent development environment and mental toughness are critical for athletes to realise their athletic potential, there is a dearth of literature on whether the talent development environment can enhance mental toughness among those athletes who are identified with athletic potential (i.e., talented athletes). Drawing on self-determination theory (Deci & Ryan, 2000), this research examined the relationships between the talent development environment, basic psychological needs satisfaction and mental toughness. Talented athletes (n = 261) completed a survey measuring key features of the talent development environment, needs satisfaction and mental toughness. The results of structural equation modelling indicated that three environmental factors (i.e., long-term development focus, holistic quality preparation and communication) were positive predictors of needs satisfaction, which then positively predicted mental toughness. The talent development environment may be considered for promoting talented athletes’ mental toughness.  相似文献

Abstract

This study was designed to assess the effects of a specifically designed perceptual-motor training program on the level of perceptual-motor development, self-concept, and academic ability of kindergarten children. Subjects for the study were 40 kindergarten children randomly assigned to 1 of 2 groups. Each group received the same kindergarten program with one exception, the experimental group was exposed to a specifically designed perceptual-motor program 30 min daily for 5 mo, while the control group received a free play period for 30 min daily. Results of the study indicated that the data tended to support the specificity of training concept. The variables showing the greatest change were the perceptual-motor tests which measured changes on specific aspects of the training program. There appeared to be some immediate transfer to academic abilities but this was not pronounced enough to suggest that perceptual-motor training was of real benefit in developing academic abilities for normal kindergarten children. In addition the follow-up test indicated no long term effects on academic performance.  相似文献   

Correlates of Physical Activity Behavior in Rural Youth     

Russell R. Pate  Stewart G. Trost  Gwen M. Felton  Dianne S. Ward  Marsha Dowda  Ruth Saunders 《Research quarterly for exercise and sport》2013,84(3):241-248

Abstract

The purpose of this study was to identify correlates of physical activity behavior in a sample of rural, predominantly African American youth. Three hundred sixty-one fifth-grade students from two rural counties in South Carolina (69% African American, median age = 11 years) completed a questionnaire designed to measure beliefs and social influences regarding physical activity, physical activity self-efficacy, perceived physical activity habits of family members and friends, and access to exercise and fitness equipment at home. After school physical activity and television watching were assessed using the Previous Day Physical Activity Recall (PDPAR). Students were classified as physically active according to a moderate physical activity standard: two or more 30-min blocks at an intensity of 3 METs (metabolic equivalents) or greater, and a vigorous physical activity standard: one or more 30-min blocks at an intensity of 6 METs or greater. According to the moderate physical activity standard, 34.9% of students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and exercise equipment at home to be significant correlates of low activity status. According to the vigorous physical activity standard, 32.1% of the students were classified as low-active. Multivariate analysis revealed age, gender, television watching, and self-efficacy with respect to seeking support for physical activity to be significant correlates of low activity status. In summary, gender and the amount of television watching were found to be the most important correlates of physical activity in rural, predominantly African American youth.  相似文献   

White Paper: functionality and efficacy of wrist protectors in snowboarding—towards a harmonized international standard     

Frank I. Michel  Kai-Uwe Schmitt  Richard M. Greenwald  Kelly Russell  Frank I. Simpson  David Schulz  Mike Langran 《Sports Engineering》2013,16(4):197-210

The wrist is the most frequently injured body region among snowboarders. Studies have shown that the risk of sustaining a wrist injury can be reduced by wearing wrist protection. Currently, there are a wide variety of wrist protection products for snowboarding on the market that offer a range of protective features. However, there are no minimum performance standards for snowboarding wrist protectors worldwide. The International Society for Skiing Safety convened a task force to develop a White Paper to evaluate the importance and necessity of a minimum performance for all wrist protectors used in snowboarding. The White Paper outlines the need for a general framework for a harmonized international standard and reviews the existing evidence. Therefore, this White Paper may serve as a common base for future discussions. The broader goal of developing and implementing such a standard is to reduce the incidence and the severity of wrist injuries in snowboarding without increasing the risk of adverse events, such as upper arm or shoulder injury. The European standard for inline skating wrist protectors (EN 14120) can serve as a starting point for efforts related to a standard for snowboard wrist protectors, but certain modifications to the standard would be required. It is hypothesized that implementation of a snowboarding wrist protector standard would result in fewer and less severe wrist injuries in the sport and could translate into more riding days for healthy snowboarders and significant health-care costs savings.  相似文献   

Research on Social Integration: What Are The Problems?     

Shirley M. Chambers  Russell W. Kay 《International Journal of Disability, Development & Education》1992,39(1):47-59

THIS LIMITED REVIEW of research on the social integration of children with disabilities in mainstreaming programs showed that there are several factors which may explain the apparent inconsistencies within the research literature. The diverse groups of individuals involved necessitate that attention be paid to pertinent variables and that care must be taken when findings are generalized to other groups of children with disabilities. An issue of particular concern was the simplistic measuring techniques employed in some research, particularly where studies relied on a single technique such as sociometry. There is limited evidence to support the increased use of multivariate statistical procedures as a means of producing more consistent findings. While most studies reviewed did not incorporate special treatments, that is other than integrated settings, invariably such treatments produced positive outcomes. Studies involving research designs which used the social acceptance of normal children as the basis for assessing social integration frequently resulted in negative findings.  相似文献   

Wider access and progression among full-time students     

Muir Houston  Hazel Knox  Russell Rimmer 《Higher Education》2007,53(1):107-146

By 2010 the UK government intends to widen access and provide experience of higher education to half of those aged up to 30. Unlike many institutions, University of Paisley (UP) has exceeded its individual target on access. It has done this by providing entry routes for students with ‘non-traditional’ qualifications. It is feared that low entry qualifications will adversely influence performance and progression statistics as wider access is pursued. Drawing on a student-attrition theory, performance and progression are investigated using data for students enrolling at UP for the first time in 2000. At UP non-traditional entry coincided with the enrolment of many students over 21. The relationships between age and performance and between age and progression are nonlinear and involve interactions with gender. Also, there are interactions between entry qualification and field of study. These relationships and interactions could complicate the important task of translating wider access into academic success.  相似文献   

Long-term impacts of two secondary school environmental studies programs on environmental behaviour: the shadows of patriarchy and neoliberalism     

Mary Breunig  Constance Russell 《Environmental Education Research》2020,26(5):701-715

Abstract

A survey of alumni of two longstanding interdisciplinary secondary school environmental studies programs revealed that the vast majority of alumni reported being engaged in pro-environmental behaviours, which they attributed to participation in the programs five to twenty-three years prior. That finding in itself is worth sharing. Digging deeper, however, revealed that most reported behaviours were in the private rather than public sphere. Women alumni reported engaging in more household and marketplace-oriented behaviours. Further, a small number of men from the rural school expressed hostility towards environmental concerns using aggressively sexist and homophobic discourse. A feminist analysis takes into account structural forces such as patriarchy and neoliberalism to interpret the findings and illuminates gendered dimensions of pro- and anti-environmental behaviours.  相似文献   

Role of the microcomputer‐based laboratory display in supporting the construction of new understandings in thermal physics     

David W. Russell  Keith B. Lucas  Campbell J. McRobbie 《科学教学研究杂志》2004,41(2):165-185

Teachers' failure to use the microcomputer‐based laboratory (MBL) more widely may be a result of not recognizing its capacity to transform laboratory activities. This research aimed to increase understanding of how MBL activities designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 15 students. Dyads addressed 10 tasks in thermal physics using a predict–observe–explain format. Data sources included video and audio recordings of students and teacher during four 70‐minute sessions, students' computer data and written notes, semistructured student interviews, and the teacher's journal. Analysis of students' discourse identified many instances in which students' initial understandings of thermal physics were mediated in multiple ways by the screen display. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities that will likely catalyze student construction of understanding. © 2004 Wiley Periodicals, Inc.
