Never blame the umpire – a review of Situation Awareness models and methods for examining the performance of officials in sport

As sport becomes more complex, there is potential for ergonomics concepts to help enhance the performance of sports officials. The concept of Situation Awareness (SA) appears pertinent given the requirement for officials to understand what is going on in order to make decisions. Although numerous models exist, none have been applied to examine officials, and only several recent examples have been applied to sport. This paper examines SA models and methods to identify if any have applicability to officials in sport (OiS). Evaluation of the models and methods identified potential applications of individual, team and systems models of SA. The paper further demonstrates that the Distributed Situation Awareness model is suitable for studying officials in fastball sports. It is concluded that the study of SA represents a key area of multidisciplinary research for both ergonomics and sports science in the context of OiS.

Practitioner Summary: Despite obvious synergies, applications of cognitive ergonomics concepts in sport are sparse. This is especially so for Officials in Sport (OiS). This article presents an evaluation of Situation Awareness models and methods, providing practitioners with guidance on which are the most suitable for OiS system design and evaluation.     

Adventure tourism and adventure sports injury: the New Zealand experience

The primary aims of this study were to establish a client injury baseline for the New Zealand adventure tourism and adventure sport sector, and to examine patterns and trends in claims for injury during participation in adventure activities. Content analysis of narrative text data for compensated injuries occurring in a place for recreation and sport over a 12-month period produced over 15,000 cases involving adventure tourism and adventure sport. As found in previous studies in New Zealand, highest claim counts were observed for activities that are often undertaken independently, rather than commercially. Horse riding, tramping, surfing and mountain biking were found to have highest claim counts, while hang gliding/paragliding/parasailing and jet boating injuries had highest claim costs, suggesting greatest injury severity. Highest claim incidence was observed for horse riding, with female claimants over-represented for this activity. Younger male claimants comprised the largest proportion of adventure injuries, and falls were the most common injury mechanism.     

商丘市普通高中学生排球活动现状的调查分析

近年来,商丘市普通高中排球活动状况不容乐观,作者采用文献资料、问卷调查、专家访谈等方法对商丘市12所普通高中排球活动的开展状况进行全面调查分析,调查发现:高中排球课的开设不足,普遍2～6学时,学生仅仅对排球和裁判有大概的了解;学校的场地器材缺少,普遍以硬排球为主,软式排球和其他排球为辅,缺乏以娱乐性为主的软式排球;48.6%的学生课外不会参加排球活动。面对现状作者认为:学校领导的重视程度、教师的教学态度和课外辅导因素对排球运动的开展起着至关重要的影响。提出了加强宣传和辅导、积极开展竞赛、领导重视等软投入和大力加强排球场地器材等硬件设施的投入、改善教师工作和学生学习排球的环境的建议。
