Ten-season epidemiological study of match injuries in men’s international rugby sevens

ABSTRACT

The aim of this study was to describe the incidence, nature and causes of match injuries in men’s international rugby sevens and to compare these to values for international rugby fifteens. The study comprised a 10-season, whole population, prospective study of the Sevens World Series. Over the ten seasons, the overall incidence of injury was 122.4 (95% CI = 116.3 to 128.9) injuries/1000 player-match-hours and the mean severity of injury was 43.0 (95% CI = 40.3 to 45.7) days-absence. There was an increasing trend in the incidence of injury over the ten-season period (slope = 5.3 injuries/1000 player-hours/season, R² = 0.68, p = 0.003) but no trend in the mean severity of injury (slope = 0.02 days/season, R² < 0.01, p = 0.971). Head/face (15.7%), knee (15.6%), ankle (15.4%) and shoulder/clavicle (11.9%) were the most common injury locations and ligament sprain (30.5%), muscle strain (16.4%), concussion (12.6%) and haematoma/bruise (10.6%) the most common types of injury sustained. Being-tackled (33.1%), tackling (23.4%), running (16.1%) and collisions (12.4%) were the most common events leading to injury. These results indicate that the burden of injury in international rugby sevens is two to three times higher than that reported for international rugby fifteens.     

第28-33届世界蹦床锦标赛竞争格局分析与中国蹦床发展策略研究

近6届蹦床世锦赛参赛国家数量呈“倒U型”发展,在运动员数量方面女运动员的参赛数量明显低于男运动员;在参赛项目上网上项目运动员的数量显著高于单跳和小蹦床项目,单跳和小蹦床项目之间的运动员数量差异不大;蹦床项目的竞争格局开始走向多极化,在全世界的竞争区域主要集中在欧洲、亚洲和北美洲,从奖牌的地域归属特征来看,我国在东京奥运会的竞争对手主要来源于欧洲和北美洲的选手;世锦赛中男子网上个人项目冠军成绩在60.795-62.280分之间,女子网上个人项目冠军成绩在55.990-57.180分之间;中国蹦床队在近6届蹦床世锦赛中一直处于奖牌榜首位,男、女运动员的综合获奖比率在逐渐接近,差距在逐渐缩小,男女网上项目实力向均衡化方向发展。     

Visiting Fortaleza: motivation,satisfaction and revisit intentions of spectators at the Brazil 2014 FIFA World Cup

The FIFA World Cup provides opportunities to attract visitors to host cities and for local residents to enjoy event-related celebrations. This paper directs attention to Fortaleza, in the north-east of Brazil, where a survey was conducted of 285 spectators to identify the relative importance of enjoyment and competitive outcomes as motives to attend games at the 2014 World Cup. The study also examined the relationship between motivation, event setting and event satisfaction and whether any differences in these relationships existed between local and visiting spectators. In the case of visitors to Fortaleza, factors that influence intentions to revisit the city were also examined. Although satisfaction did not have an impact on visitation intentions, visitors were strongly influenced by competitive motives associated with the team they support. In comparison, local residents were more motivated by event excitement. The need to recognize the propensities of different types of spectators and the complexity of the relationship between spectators and the event setting are discussed.
