- Abstract Objectives: To investigate the correlation between exposure to match play for football players in European clubs during the months prior to the World Cup 2002 and the injuries and performance of these players during the World Cup. Methods: The team doctors at eleven of the best football clubs in Europe prospectively recorded player’s exposure and injuries during the 2001-2002 season (July 2001-May 2002). Sixty-five players participated in the World Cup in Korea/Japan (June 2002). During the World Cup, the clubs reported injuries sustained by these players, and their performance was evaluated by three international experts. Results: The number of team matches during the season varied between 40 and 76 for the different countries involved. The individual player had a mean of 36 matches during the season. Top players played more matches, especially during the final period of the season. Players that participated in the World Cup (WC players) played more matches during the season compared to players who did not participate in the World Cup (46 vs 33 matches). WC players did not show an increased risk for injury during the season. Twenty-nine per cent of the WC players incurred injuries during the World Cup and 32% performed below their normal standard. The players who under-performed in the World Cup played more matches during the 10 weeks prior to the World Cup compared to those who performed better than expected (12.5 vs 9, p< 0.05). Twenty-three (60%) of the 38 players who had played more than 1 match/week prior to the World Cup incurred injuries or underperformed during the World Cup. Conclusions: There is a considerable variation in the number of matches played per season in European professional leagues. Top-level players are obliged to play many matches especially during the final period of the season.

- The Swedish male senior national football team was followed prospectively between 1991 and 1997. During these 6 years, the team played 73 official matches and had three training camps. The senior author (J. E.) attended 57 of these matches and the three training camps and these matches and training camps, are included in the present study. Exposure to football was recorded individually for each player. The team physician examined all injuries. Total exposure was 7245 h (6235 training and 1010 match hours) and there were 71 injuries (40 training and 31 match injuries). Five (16%) of the match injuries were major, with more than 4 weeks of absence from football. The injury incidence during training was 6.5/1000 h and the injury risk during matchplay was 30.3/1000 h. A significantly higher injury incidence was found for matches lost compared to matches won or drawn (52.5 vs. 22.7/1000 h, P=0.026). No statistically significant difference for injury was found between competitive matches and friendly matches. No difference was found between home and away matches or matches on neutral ground. The risk for injury when playing in a national team compares with previously reported figures for professional football at a high level.

- The long-term development of injury risk in Swedish male elite football was studied. Two prospective cohort studies from seasons 1982 and 2001 were compared with respect to exposure to football, injury incidence and injury severity.The mean number of training sessions during the season had increased by 68% between 1982 and 2001 (142 vs. 238, P<0.001), whereas teams played more matches in 1982 (49 vs. 41, P=0.02). The total exposure to football had increased by 27%. Three out of four players incurred an injury in both seasons. In 2001, players suffered more training injuries due to an increased training exposure. Accounting for risk exposure, there was no difference in injury incidence or severity between the two seasons. The incidence was 8.3 injuries/ 1000 h of total exposure (4.6 in training and 20.6 in matches) in 1982, compared to 7.8 1000 h−1 (5.2 in training and 25.9 in matches) in 2001. Major injuries accounted for 9% of all injuries, corresponding to an incidence of 0.8 /1000 h of football, in both seasons.A trend from semi-professionalism to full professionalism in Swedish elite football was seen during the last two decades. The injury risk did not change over the same period.
