Abstract

Previous studies on the kinematics of the golf swing have mainly focused on group analysis of male golfers of a wide ability range. In the present study, we investigated gross body kinematics using a novel method of analysis for golf research for a group of low handicap female golfers to provide an understanding of their swing mechanics in relation to performance. Data were collected for the drive swings of 16 golfers using a 12-camera three-dimensional motion capture system and a stereoscopic launch monitor. Analysis of covariance identified three covariates (increased pelvis–thorax differential at the top of the backswing, increased pelvis translation during the backswing, and a decrease in absolute backswing time) as determinants of the variance in clubhead speed (adjusted r ² = 0.965, P < 0.05). A significant correlation was found between left-hand grip strength and clubhead speed (r = 0.54, P < 0.05) and between handicap and clubhead speed (r = ?0.612, P < 0.05). Flexibility measures showed some correlation with clubhead speed; both sitting flexibility tests gave positive correlations (clockwise: r = 0.522, P < 0.05; counterclockwise: r = 0.711, P < 0.01). The results suggest that there is no common driver swing technique for optimal performance in low handicap female golfers, and therefore consideration should be given to individual swing characteristics in future studies.  相似文献   

Rankings in professional men’s tennis: a rich but underutilized source of information     

Machar Reid  Stuart Morgan  Tania Churchill 《Journal of sports sciences》2013,31(10):986-992

Abstract

Success in professional tennis is measured, at least in part, by rankings. However, there is little quantitative evidence to inform stakeholders regarding what represents the typical ranking progress of top-ranked players. The objective of this study was therefore to compare the ranking trajectories of male players whom achieved peak professional rankings in the Top 250, 175, 100, 50, 20 and 10. The 11,396 birthdates and weekly professional rankings of all players between 27 August 1973 and 31 October 2011 were collated. The peak ranks for each athlete according to their both chronological age and number of years on tour were identified and athletes were categorised into one of six career–peak ranking bands. One-way analysis of variance tests confirmed distinctive ranking trajectories, which were most pronounced among Top 10 players. The rankings of these players were statistically distinguishable following players’ second year on tour or by 17 years of age. The ranking signature of all Top 100 players emerged as significantly different to players that failed to enter the Top 100 by their fourth year on the tour. Indeed, the representation of ranking as a function of years on tour should be considered for use by tennis policy-makers in the future.  相似文献   

Early childhood special education pictorial literacy activities for young children with disabilities     

Gerard Giordano  Sheela Stuart 《Early Childhood Education Journal》1994,21(3):44-46

Summary Alternative literacy activities can be adapted to complement the speech and language programs that have been developed to assist learners with disabilities. Pictorially based alternative literacy programs may involve rebus symbols, augmentative and alternative communication devices, or picture reading. Because these programs do not assume extensive language development, they can be appropriate for children with severe learning problems as a foundation or replacement for typical early reading activities.  相似文献   

Visually impaired children: Development and implications for education     

Michael J. Tobin  Nick Bozic  Graeme Douglas  John Greaney  Stuart Ross 《European Journal of Psychology of Education - EJPE》1997,12(4):431-447

This paper examines some of the models used for conceptualizing the possible developmental implications of blindness and severe visual impairment. It takes up the question of the significance in infancy of certain skills and proficiencies, especially motor, that may be impeded by the lack of vision. The paper then addresses such issues for the school age child as access to literacy, with the emphasis being on ways of mitigating the potentially educationally handicapping consequences of visual disability. Educational technology is cited as one of the principal means available to teachers for meeting these challenges, and examples are given of procedures and devices that are being explored. A central argument is that for psychologists, teachers, and educational technologists the search must be to pinpoint the specific and changing needs of the individual learner.  相似文献

Pupil guidance: An integral part of teacher education and development in Scotland?     

Valerie Wilson  Stuart Hall  John Hall 《Teaching and Teacher Education》2007

Many schools throughout the UK are experiencing challenging behaviour from pupils and high levels of absence and exclusion as they seek to implement initiatives aimed at raising pupil attainment [National Audit Office (2005). Improving school attendance, London: The Stationery Office]. These initiatives often presuppose that pupils will receive adequate levels of guidance and support to help them make curricular, personal, social, and health decisions. However, little is heard from teachers and students undertaking initial teacher education courses on how they have been prepared for this extended role of supporting increasing diverse student populations; nor do we know how they define guidance/pupil support and integrate this with their concept of the professional role of a teacher. This article presents evidence from a one-year study of pupil support in Scotland commissioned by the Scottish Executive Education Department. The study provided evidence for The National Review of Guidance Provision in Scotland [Scottish Executive (2003). The national review of guidance. Edinburgh: Scottish Executive; Scottish Executive (2005). Happy, safe and achieving their potential. Edinburgh: Scottish Executive]. The study explored the views of all 32 local authorities in Scotland, a sample of students in training in two universities and teachers, headteachers and pupils in eight case study schools, and also a sample of their parents. This article focuses specifically on the findings relating to teachers and students in training. It identifies the ways in which they support pupils and how well they think they have been prepared for that task. Two dominant models of pupil support emerge from these data: an embedded and a specialist approach, and these vary according to school and education sector. Primary school teachers were more likely to embed pupil support into their concept of being teachers, whereas secondary teachers perceived it to be a separate, specialist function, which many were reluctant to undertake. Some implications for teacher education are highlighted.  相似文献   

RESILIENCE,BULLYING, AND MENTAL HEALTH: FACTORS ASSOCIATED WITH IMPROVED OUTCOMES          下载免费PDF全文

Brian Moore  Stuart Woodcock 《Psychology in the schools》2017,54(7):689-702

Resilience is associated with bouncing back from adversity, and the term currently enjoys significant popular appeal. However, understanding of resilience is often superficial. The current paper examined 105 primary and high school students’ experiences of resilience and bullying, and considered resilience as a hierarchical factorial model. The study found that higher levels of resilience subfactors were a protective factor regarding depression and anxiety; that individuals with poorer resilience were more likely to engage in bullying behaviors; that individuals with poorer levels of resilience were more likely to be victims of bullying; and, that gender did not appear to be a major variable regarding resilience and bullying. These findings suggest that resilience interventions that focus on improving specific resilience elements including optimism, trust, tolerance, sensitivity, and impairment may be more efficacious than interventions focused on other resilience elements.  相似文献

A framework for evidencing assessment validity in large-scale,high-stakes international examinations     

Stuart Shaw  Victoria Crisp  Nat Johnson 《Assessment in Education: Principles, Policy & Practice》2012,19(2):159-176

It is important for educational assessment bodies to demonstrate how they are seeking to meet the demands of validity. The approach to validity taken here assumes a ‘consequentialist’ view where the appropriacy of the inferences made on the basis of assessment results is seen as central. This paper describes the development of a systematic approach to the collection of evidence that can support claims about validity for general qualifications. An operational framework was developed drawing on Kane (2006 Kane, M.T. 2006. “Validation”. In Educational measurement, 4th ed., Edited by: Brennan, R.L. 17–64. Westport, CT: Praeger.  [Google Scholar]). The framework involves a list of inferences to be justified as indicated by a number of linked validation questions. For each question various data would be gathered to provide ‘evidence for validity’ and to identify any ‘threats to validity’. The structure is designed to be accessible for operational users. This paper describes the development of the proposed framework and the types of methods to be used to gather relevant evidence.  相似文献
