Video Analysis of Soccer Players’ Injuries during the 2010 World Cup Games

هدف از تحقيق حاضر تجزيه و تحليل ويدوئي آسيب هاي بازيكنان فوتبال در بازي هاي جام جهاني 2010 بود. بدين منظور تمامي بازي هاي جام جهاني از طريق تجزيه و تحليل ويدوئي بررسي شد و اطلاعات آن ن(تعداد آسيب، سازوكار وقوع آسيب، زمان بروز آسيب، نوع برخورد منجر به آسيب و منطقه وقوع آسيب در زمين بازي) از طريق ثبت در فرم گزارش آسيب بدست آمده است. در تحقيق حاضر كه از نوع توصيفي –تحليلي مي باشداز آزمون آماري مجذور كاي 2 X راي تجزيه‌ و تحليل داده‌ها استفاده شد. نتايج نشان داد 92 آسيب طي 64 مسابقه يا 3/39 آسيب در هر 1000 ساعت مسابقه به‌ وقوع پيوسته است. بيشترين ميزان بروز آسيب در 15 دقيقۀ انتهايي نيمۀ دوم (دقايق 90 – 76) رخ داده است (0/05>P). مبارزۀ هوايي (38/2 درصد) و تكل شدن (7/21 درصد) بيشترين سازوكار به‌وجودآورندۀ آسيب بوده‌اند (0/05

The aim of this study was the video analysis of soccer players' injuries in the 2010 World Cup games. Therefore, all World Cup games were reviewed through video analysis and their information (the number of injuries, the mechanism of injuries, the time of incidence, the type of accident leading to injuries and the injury occurrence area in the pitch) were recorded in the injury report form. In the present study that was descriptive-analytical, Chi square test (X2) was used for statistical analysis. Results showed that 92 injuries occurred during 64 games or 39.3 injuries per 1000 hours of game. Most incidence of injuries occurred in the final 15 minutes of the second half (minutes of 76-90) (P<0.05). Air challenging (28.3%) and receiving tackles (21.7%) were the most common mechanisms causing injuries (P˃0.05). The area 5 with 20.7% and then areas 2 and 8 with equal ratio of 18.5% had the most percentage of injuries (P<0.05). Also, 84.8% of injuries happened by hits (P<0.05). The incidence of injuries in these games was lower than previous world cups; this can be due to the stricter coaching rules to maintain the health of players in recent years, a difference in the definition of injury, the different game system, differences in duration and type of fitness training and bodybuilding and different methods of data collection.
