Perceptual-cognitive expertise of handball coaches in their young and middle adult years

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.  相似文献   

‘Tours of Imperialism’: Cricket and Cultural Transfer in South Africa, 1880–1910     

Dean Allen 《国际体育史杂志》2016,33(15):1717-1729

Abstract

Few can deny the significance of sport in today’s South Africa. The sporting structures upon which this is based were first introduced to the country by the British in the late nineteenth century. In line with policies of cultural imperialism, sports such as cricket were promoted at this time as part of a wider political agenda that encouraged the adoption of an ‘English’ way of life in the region. Sports tours, most notably cricket, were a fundamental part of this cultural transfer between the ‘Mother Country’ and her colonies in Southern Africa. To underpin the study of transnational linkages and transfer in African sports, this paper will offer an historical overview of how ‘British-styled’ sport arrived in South Africa and how the early cricket tours between England and South Africa were constructed to promote distinct political and cultural connections. This paper will explore the early development of cricket in South Africa and investigate its symbiotic link to British imperialism and colonialism via the first tours and sporting exchanges that took place. The origins of the game in South Africa will be examined as well as its development up to 1910 (the date of Union in South Africa) as the site of a constructed transnational 'brotherhood' between Britain and its most coveted African colonies.  相似文献   

Asian Martial Arts: The Anarchic Legacy of the War Machine     

Barry Allen 《国际体育史杂志》2016,33(9):882-892

Abstract

The renaissance of Asian martial arts is a conspicuous example of cultural hybridity in a global setting. Globalization brings these arts under the dual sway of cinema and sport to a degree unprecedented in their history. This pull, which I describe in terms from Deleuze and Guattari as deterritorialization, creates new challenges for Asian martial arts practice. To explore these challenges and their stakes, I demonstrate the relevance of the concept of the war machine from Deleuze and Guattari, and discuss their distinction between weapons and tools as it bears on Asian martial arts history and practice.  相似文献   

A review of tennis racket performance parameters     

Tom Allen  Simon Choppin  Duane Knudson 《Sports Engineering》2016,19(1):1-11

The application of advanced engineering to tennis racket design has influenced the nature of the sport. As a result, the International Tennis Federation has established rules to limit performance, with the aim of protecting the nature of the game. This paper illustrates how changes to the racket affect the player-racket system. The review integrates engineering and biomechanical issues related to tennis racket performance, covering the biomechanical characteristics of tennis strokes, tennis racket performance, the effect of racket parameters on ball rebound and biomechanical interactions. Racket properties influence the rebound of the ball. Ball rebound speed increases with frame stiffness and as string tension decreases. Reducing inter-string contacting forces increases rebound topspin. Historical trends and predictive modelling indicate swingweights of around 0.030–0.035 kg/m² are best for high ball speed and accuracy. To fully understand the effect of their design changes, engineers should use impact conditions in their experiments, or models, which reflect those of actual tennis strokes. Sports engineers, therefore, benefit from working closely with biomechanists to ensure realistic impact conditions.  相似文献   

Adjustment scales for preschool intervention: Extending validity and relevance across multiple perspectives     

Rebecca Bulotsky‐Shearer  John Fantuzzo 《Psychology in the schools》2004,41(7):725-736

A series of studies extended psychometric research on the Adjustment Scales for Preschool Intervention (ASPI). The ASPI is a multidimensional measure of preschool emotional and behavioral adjustment for use within formal early childhood educational programs. These studies used a multiple method, multisource approach to provide additional evidence for the reliability and validity of the ASPI. Findings documented inter‐rater reliability of the ASPI across key informants within early childhood educational programs—teachers and teacher assistants. Findings supported concurrent validity of the ASPI with direct observations of preschool classroom adjustment problems and the developmentally salient constructs of temperament and emotion regulation. Implications for policy, practice, and future research are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 725–736, 2004.  相似文献   

Bullying and the Unique Socioemotional Needs of Gifted and Talented Early Adolescents: Veteran Teacher Perspectives and Practices     

William T. Allen Jr. 《Roeper Review》2017,39(4):269-283

Much is written at the elementary school level concerning bullying and the socioemotional needs of gifted and talented (GT) students; however, in the last 10 years, little qualitative research exists concerning the early adolescent GT age group. In the social environment of classroom life, early and current research indicates that many of these students experience neurotic perfectionism, overexciteabilities (OEs), developmental asynchrony, and bullying. The formation of autonomous classes (GT-only classes) has afforded some hope concerning the amelioration of such problems; nevertheless, in this study, detailed evidence of classroom bullying in the form of social ostracism and teasing has been found with this GT age group. If left unchecked, psychological autopsies have shown these students suffering emotional difficulties and even committing suicide as a result of school and classroom torment. With such potential for classroom bullying problems, few studies address what veteran teachers of early adolescent GT students do to keep students psychologically safe. Within the social milieu of classroom life, and in comparison to research standards, this study explores three efficacious teacher perspectives and practices.  相似文献
