The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players. 相似文献

The purpose of this paper is to theoretically and empirically explore how public e-procurement policies are translated into practice. The theoretical argument draws on actor network theory (ANT), coupled with Colebatch’s [Colebatch, H. K. (2002). Policy (2nd ed.). Maidenhead, Open University Press.] social construct of policy, to analyze the actors, actions, and circumstances through which understanding of public e-procurement comes to stabilize (or not) into a coherent policy for action. Drawing on three case studies of central government agencies in Italy, Scotland, and Western Australia, we suggest new intellectual perspectives and methodological heuristics that may assist researchers and practitioners analytical efforts in examining sociotechnical change and the implications for policy development and implementation. 相似文献

The aim of this study was to explore the relationships between dimensions of social support and components of performance in tennis. A post-match performance measure was completed by 144 British tournament tennis players. Principal components analysis yielded eight components, labelled Execution of (Flexible) Plan, Loss of Composure, Feeling Flat, Positive Tension, Worry, Flow, Effective Tactics and Double Faults. Before the match, 46 players had also completed the Interpersonal Support Evaluation List. Stepwise regression analyses revealed significant effects of the Belonging and Appraisal dimensions of the Interpersonal Support Evaluation List on five of the performance components. The correlations between total support and four of these performance components were also significant. Logistic regression analyses revealed no significant effects of the dimensions of the Interpersonal Support Evaluation List or Total Support upon winning versus losing. Effects of social support upon performance were therefore only apparent when attention was focused on the components of performance. 相似文献

We provide an overview of some of the outstanding papers published in the Journal over the last 25 years within the discipline of psychology. Altogether, almost 300 papers had been published in the Journal under the psychology banner at the start of its silver anniversary year. The greatest contribution of papers has come from the motor control and learning and sport psychology sub-areas, with papers focusing on exercise psychology being a more recent addition. Prominent research themes that have emerged from each of the different sub-areas are reviewed and some notable omissions highlighted. Finally, some issues for sport and exercise psychologists to consider in coming years are briefly highlighted. 相似文献

This paper reports on an investigation into how staff teaching in compressed courses can encourage student engagement and enhance student use of learning time, despite significant restraints of time as well as distance. Typically these courses (described here as units) are expected to have comparable learning outcomes to their full-semester counterparts and provide an opportunity for students to either retake failed units or to acquire credit for their chosen degrees in accelerated time. Organising teaching and learning through intensive modes of delivery may require different approaches to curriculum development and pedagogy compared to traditional unit planning and delivery, especially when the intensive delivery utilises online technologies. This paper explores strategies employed by successful intensive mode teachers in the development and delivery units for maximised student engagement. It concludes that many of these strategies are equally applicable in online and distance education regardless of the unit being intensive or otherwise. 相似文献
