To study the effect of changes in the score and of different playing positions, as well as the effect of recovery time on injury incidence during Fédération Internationale de Football Association (FIFA) World Cups.
Prospective injury surveillance at three international championships in 2002, 2006 and 2010. Official match statistics were obtained for all the games played in the three championships.
2002, 2006 and 2010 FIFA World Cups.
National team players as well as the team doctors reporting all the injuries at the 2002, 2006 and 2010 FIFA World Cups.
Injury incidence and incidence rate ratios.
There were statistically significant differences in injury incidence related to changes in the score (p=0.026) and to the teams' current drawing/losing/winning status (p=0.008). Injury incidence was lowest (54.8/1000 match-hours (mh), 95% CI 46.4 to 64.3) during the initial 0-0 score and highest (81.2/1000 mh, 60.5 to 106.8) when the score was even but goals had been scored. Winning teams had a tendency towards a higher injury incidence (81.0/1000 mh, 67.5 to 96.4) than losing or drawing teams (55.5/1000 mh, 44.4 to 68.4 and 59.7/1000 mh, 51.8 to 68.6, respectively). There were also statistically significant differences in injury incidence between the playing positions (p<0.001), with forwards having the highest injury incidence (85.7/1000 mh, 69.8 to 104.2). There was a linear relationship (p=0.043) between an increasing number of recovery days between matches and a higher injury incidence.
There is a considerable variation in injury incidence during a match in international men's football related to changes in the score. Players in a winning team run a higher risk of suffering an injury than players in a drawing or losing team. Identifying time periods with a high injury incidence may be of major importance to players and team personnel, as it may enable them to take precautions.
研究国际足联（FIFA）世界杯比赛中比分变化、不同场上位置以及恢复时间对损伤发生率的影响。
2002 年、2006 年和 2010 年三次国际锦标赛的前瞻性损伤监测。获取了三届锦标赛所有比赛的官方比赛数据。
2002 年、2006 年和 2010 年 FIFA 世界杯。
2002 年、2006 年和 2010 年 FIFA 世界杯国家队球员以及报告所有伤病的队医。
损伤发生率和发生率比。
与比分变化（p=0.026）和球队当前的平局/输/赢状态（p=0.008）相关的损伤发生率存在统计学差异。在初始 0-0 比分时，损伤发生率最低（54.8/1000 比赛小时（mh），95%CI 46.4 至 64.3），而当比分持平但有进球时，损伤发生率最高（81.2/mh，60.5 至 106.8）。获胜球队的损伤发生率呈上升趋势（81.0/mh，67.5 至 96.4），而输球或平局球队的损伤发生率较低（55.5/mh，44.4 至 68.4 和 59.7/mh，51.8 至 68.6）。不同场上位置的损伤发生率也存在统计学差异（p<0.001），前锋的损伤发生率最高（85.7/mh，69.8 至 104.2）。比赛之间的恢复天数与损伤发生率之间存在线性关系（p=0.043），即恢复天数越多，损伤发生率越高。
国际男子足球比赛中，比分变化与比赛期间的损伤发生率有很大差异。与平局或输球的球队相比，获胜球队的球员受伤风险更高。确定高损伤发生率的时间段对球员和球队人员可能非常重要，因为这可能使他们能够采取预防措施。
