Sports vision training: A review of the state-of-the-art in digital training techniques     

L. Gregory Appelbaum  Graham Erickson 《International review of sport and exercise psychology》2018,11(1):160-189

Athletes need excellent vision to perform well in their sports, and many athletes have turned to vision training programs as a way to augment their traditional training regimen. The growing practice of ‘sports vision training’ relies on the notion that practice with demanding visual perceptual, cognitive, or oculomotor tasks can improve the ability to process and respond to what is seen, thereby improving sport performance. This enterprise is not necessarily new, but has been advanced greatly in the past few years by new digital technology that can be deployed during natural training activities, by perceptual-learning-inspired training programs, and by virtual reality simulations that can recreate and augment sporting contexts to promote certain sports-specific visual and cognitive abilities. These improved abilities may, in turn, instill a competitive advantage on the playing field, underscoring the potential value of these approaches. This article reviews emerging approaches, technologies and trends in sports vision training. Where available, critical review of supporting research is provided.  相似文献   

Charting the development of sport expertise: challenges and opportunities     

Damian Farrow  Machar Reid  Tim Buszard  Stephanie Kovalchik 《International review of sport and exercise psychology》2018,11(1):238-257

This review poses three key issues that will progress our understanding of the sport expertise literature and its translational scientific impact. Primarily relying on research conducted in interceptive sport tasks, and to a lesser extent team sports, we review the perceptual-cognitive skills of sports experts and explore the challenge of designing a sufficiently representative task to examine expertise. We focus on the methodological challenges presented by the reciprocal relationship between players’ action capabilities and their perceptual-cognitive skill. Second, we consider the need for a paradigm shift in the experimental approach used when examining the development of sport expertise. In short, a shift from traditional expert-novice designs to more prospective longitudinal designs that cross-sectionally track the development of expertise is discussed. The final issue considers how the volume of in situ data now collected provides a rich source of information that sport expertise researchers have only begun to consider and integrate with more traditional sport psychology research. We demonstrate how statistical approaches that have described the likely trajectories of expert performers on their journey toward expertise coupled with more traditional qualitative experimental approaches can provide useful insights into the development of psychological performance skills and more broadly sport expertise.  相似文献   

Attentional Patterns Involved in Coping Strategies in a Sport Context     

Marie-Héloïse Bardel  Tim Woodman  Fabienne Colombel  Christine Le Scanff 《Research quarterly for exercise and sport》2013,84(4):597-602

We investigated the relationship between coping strategies and attentional bias after a sport competition. We administered the Ways of Coping Checklist (Paulhan, Nuissier, Quintard, Cousson, & Bourgeois, 1994) to 145 athletes immediately after they had participated in a sport competition. We also assessed attentional bias using a dot probe detection task. Results revealed that emotion-focused coping strategies led athletes to orient their attention away from threat, whereas athletes who adopted problem-focused coping strategies focused their attention toward threat. More precisely, problem-focused coping strategies are related to a facilitated detection of threat, not to disengagement difficulties. The vigilance attentional bias seems to be a compensatory strategy to cope with a stressful situation, such as sport competition.  相似文献   

Three-dimensional anthropometric analysis: Differences between elite Australian rowers and the general population     

Natasha Schranz  Grant Tomkinson  Tim Olds  Nathan Daniell 《Journal of sports sciences》2013,31(5):459-469

Abstract

The aim of this study was to quantify the anthropometric differences between elite senior Australian rowers and the Australian adult population using three-dimensional (3D) whole-body scanning. The dimensions of senior rowers competing at the 2007–2008 Australian Rowing Championships were compared with those of an age-matched sample of Australian adults. Mass, height, and sitting height were measured before the participants underwent a 3D whole-body scan, with lengths, breadths, girths, cross-sectional and surface areas, and volumes extracted from each scan. Differences in means and variability between the two groups were expressed as standardized effect sizes and ratios of coefficients of variation. Heavyweight rowers were generally much larger than the general population in absolute size, with 3D dimensions and height and mass showing the largest effects. In contrast, lightweight rowers were generally similar or smaller in absolute and proportional size. The dimensions of rowers, especially the lightweights, were also generally less variable than those of the general population. The greatest differences between elite rowers and the general population were seen in dimensions that could not be captured without 3D scanning, such as segmental volumes and cross-sectional areas.  相似文献   

Influence of playing standard on the physical demands of professional rugby league     

Tim J. Gabbett 《Journal of sports sciences》2013,31(10):1125-1138

Abstract

In this paper we report on two studies that investigated the physical demands of professional rugby league match-play. Instudy one, National Rugby League (NRL) and National Youth Competition (NYC) players underwent global positioning system (GPS) analysis during competitive matches. No differences (P > 0.05) were observed between playing standards for minutes played, total distance covered, or the distances covered at low and high speeds. However, NRL players engaged in significantly more repeated high-intensity effort bouts than NYC players (13.1 ± 0.8 bouts vs. 9.7 ± 1.1 bouts). Reductions in physical performance occurred from the first to second half for both NRL and NYC players. In study two, we investigated, in the same players, the physical demands of professional rugby league match-play when players were competing in trial and regular fixture matches. The locomotor demands of trial matches were lower than fixture matches, with players covering less distance per minute of match-play, including less distance at low and high speeds. Players were also less likely to engage in repeated high-intensity effort bouts in trial matches than fixtures. These findings demonstrate that neither NYC matches nor NRL trial matches adequately reflect the intense physical demands of NRL fixture matches.  相似文献   

Comparison of the prevalence and treatment of hypertension in two populations in the United States: Masters swimmers versus the NHANES population     

Sally K. Guthrie  Steven R. Erickson  Matthew S. Lau 《Journal of sports sciences》2013,31(9):930-935

Abstract

This research compares the prevalence of hypertension in a group of adult masters swimmers with an age and sex matched cohort from the 2008 NHANES (National Health and Nutrition Examination Survey), used to represent the general population in the United States. Masters swimmer data were obtained from a one-time survey of all United States Masters Swimming (USMS) members. Both datasets included demographics, drug therapy, diseases and health status. Characteristics of swimming sessions as well as perceptions of impact of medications on exercise were also collected from the USMS respondents. Of 1346 completed surveys from USMS respondents, 15.8% self-identified as having hypertension while 36.2% participants in the NHANES survey suffered from hypertension (P < 0.001). The two groups were well matched for age and gender but the USMS group was primarily Caucasian, higher income, higher education, and reported higher health status. In the USMS group, not only was hypertension less prevalent but those who suffered from hypertension took fewer medications (P = 0.04) to manage their hypertension than in the NHANES group. Additionally, The USMS group suffering from hypertension considered themselves healthier (P < 0.001) than the NHANES group.  相似文献   

Team-Referent Attributions Among Sport Performers     

Iain Greenlees  Andrew Lane  Richard Thelwell  Tim Holder  Gina Hobson 《Research quarterly for exercise and sport》2013,84(4):477-487

Abstract

The aim of this study was to develop and validate a team-referent attribution scale. Conducted over three studies, Study 1 modified items from McAuley, Duncan, and Russell's (1992) Causal Dimension Scale II by rewording items to reflect team attributions and adding one item per factor. This led to the development of a 16-item scale (Causal Dimension Scale-T, CDS-T). Study 2 tested competing models of attribution theory among a sample of 433 team sport players. Confirmatory factor analysis indicated strongest support for a four-factor model (robust comparative fit index = .961; root mean squared error of approximation = .054). Study 3 tested the predictive validity of the scale among a sample of 201 team players. Results indicated that winners reported more internal and stable attributions than losers. Further, performances perceived as successful were associated with stable attributions. The results of the study, therefore, suggest that the CDS-T provides a valid measure of team-referent attributions in sport.  相似文献   

In search of invariant athletic behaviour in sport: An example from championship squash match‐play     

Tim McGarry  Ian M. Franks 《Journal of sports sciences》2013,31(5):445-456

Analysis of competitive sport performance from a priori observation is frequently used to prepare an athlete for a future contest. This practice necessarily assumes that the observed athletic behaviours are invariant, in that the data from an earlier contest apply to the next. We report different analyses of championship squash matches from 1987 and 1988 in search of such invariance and thus a general signature of athletic behaviour. The results show that once the preceding condition to an athletic response (shot) becomes more detailed, by either accounting for where on court the previous shot was played to, or by pairing the previous shot with its own antecedent, the corresponding response becomes more predictable (P > 0.25). This is especially the case for a squash champion when the forehand and backhand characteristics of his shot response are accounted for. The finding that the champion is more consistent if his forehand and backhand shot responses to a preceding shot are analysed separately, shows that the level of analytic detail is an important consideration if the derived information from sport analysis is to prepare an athlete reliably for future sport competition. Finally, we consider sport competition from an ecological perspective with regard to the natural organization and stability of non‐linear systems in an attempt to explain the empirical data.  相似文献   

Aerobic exercise and type a behaviour     

Lori A. Schmied  Hannah Steinberg  Tim Moss  Elizabeth A. Sykes 《Journal of sports sciences》2013,31(5):433-445

The Type A behaviour pattern is a well‐documented, if controversial, risk factor for coronary heart disease. Surprisingly, relatively little work has been reported on ways of modifying this behaviour pattern. Aerobic exercise, with its demonstrated benefits for both cardiovascular reactivity and psychological ‘well‐being’, is a promising treatment. The literature is reviewed and recommendations are made for practical applications and future research.  相似文献   

Health-inclusive higher education: listening to students with disabilities or chronic illnesses     

Kate Hughes  Tim Corcoran  Roger Slee 《高等教育研究与发展》2016,35(3):488-501

This paper reports on a small-scale project undertaken with tertiary students who identified as having an impairment either at enrolment or by registering with the university's Disability Support Unit (DSU). The aim of the study was to explore with these students ways in which the university was currently meeting their academic support needs and the ways in which these needs might be better met. Consistent with the definition of disability within the Australian Disability Discrimination Act, it became apparent that a significant number of students who identified with that definition, or sought help from disability services, also presented with needs arising from chronic illness. The majority of participants cited an emotional or psychological illness, rather than a physical, intellectual or sensory one, as a possible precursor to difficulties in engagement with the university. We conclude by considering whether commonly used institutional categories are apposite to an understanding of the ways in which students perceive themselves and, importantly, their engagement with the university and success within it.  相似文献
