In the world of sport, athletes and their trainers see competitive emotions and, in particular, performance anxiety as one of the most important factors likely to influence the outcome of a sports competition. These emotions attract such vast interest because even today they continue to raise many questions. While positive emotions are generally considered to be largely facilitative to an athlete's performance, the link between negative emotions, and particularly competitive anxiety, and performance seems less unanimous. Some view anxiety as a phenomenon which hampers performance; for them, an anxious athlete is a fragile one. Others view anxiety as a driver and give as examples those athletes who only perform well under the pressure of competition and the anxious state it elicits. There is currently no single model for the relationship between anxiety (or emotions) and performance on which everybody agrees, in spite of the fact that the scientific community has been striving for some time to better understand the links between them. Research carried out to confirm these links has produced inconsistent results which are difficult to interpret as the variables measured (anxiety, emotional states, performance) and the framework of the studies (characteristics of the participants, importance of the sports event) most often differ. 相似文献

Background
Rehabilitation of injuries in the upper extremity and reestablishment of muscle strength throughout the range of motion in overhead movements, are the major concerns of athletes and coaches in the sports field.Purpose
To determine the effect of eight-week “gyroscopic device” mediated resistance training exercise on grip strength, wrist and shoulder strength and proprioception, and upper extremity performance, in participants with impingement syndrome or tennis elbow.Design and methods
For this study, in a university rehabilitation clinic 45 volleyball players (aged 22–28) purposefully were selected and divided into 3 groups: shoulder impingement (group I), tennis elbow (group II), and control (group III). The experimental groups performed the “gyroscopic device” mediated resistance training, three sessions a week over 8 wks. Grip strength, wrist and shoulder strength and proprioception, and upper extremity performance were measured before and after implementation of the intervention (eight-week resistance training using a “gyroscopic device”) using a hand hold dynamometer, isokinetic dynamometer, and Y balance test respectively.Results
After 8 weeks of “gyroscopic device” exercise, improvement in the shoulder, wrist and grip strength, shoulder and wrist proprioception and performance scores of both experimental groups was significant. There were no significant differences between study groups I and II, both groups, however, demonstrated significant differences when compared to the control group, but between group I and the control group, and between group II and the control group, the difference was significant. However, no significant change was seen in the control group.Conclusions
Due to the significant effects of the “gyroscopic device” mediated exercise on grip strength, wrist and shoulder strength and proprioception, and performance of the upper extremity, use of the exercise can be recommended for subjects with impingement syndrome or tennis elbow impairment in measured variables. More research is needed to confirm the result of this study. 相似文献59.

The study examines the impact of one-on-one simulation for medication administration (MA) on prelicensure student preparedness for and performance of MA in the clinical setting.We used a prospective quasi-experimental interventional study applying Kirkpatrick's model to the simulation experience addressing MA.Simulation increased student preparedness. Students' critical thinking and approach during the MA process were significantly higher in the clinical setting.One-on-one MA simulation is an effective educational method for improving student learning and performance in practice. 相似文献
