   Objective: To create a model for the precompetition medical assessment (PCMA) of international elite football players aimed at identifying risk factors and to assess the feasibility of standardized requirements for teams from countries with variable medical standards.Design: Descriptive feasibility study.Setting: Medical assessment of professional football players before a major international competition.Participants: Thirty-two national football teams comprising 736 players participating in the 2006 FIFA World Cup.Intervention: A standardized football-specific PCMA was developed, and all team physicians were asked to perform the PCMA before the 2006 FIFA World Cup.Main Outcome Measures: Response rate, completeness of documentation forms, and quality of data.Results: Of all 32 teams participating in the 2006 FIFA World Cup, the precompetition assessment forms of 26 teams (response rate 81%) were returned. Of the initial target population of 736 players, the data of 582 players (79%) were analyzed. The average completeness of the forms ranged from 34% to 94% among teams and average completeness of the different sections of the forms from 78% to 98%. Quality of data provided varied considerably.Conclusion: The response rate of 81% demonstrated that a standardized approach is possible, whereas results and quality of data required adaptations of the form and review of the implementation procedure.

Precompetition Cardiac Assessment of Football Players Participating in the 2006 FIFA World Cup Germany (Vorwettkampf-Herz-Untersuchung der an der 2006 FIFA Fussball-Weltmeisterschaft in Deutschland teilnehmenden internationalen Elite-Fußballer).

   Objectives: To develop a precompetition medical assessment (PCMA) of elite football players aimed at identifying risk factors for sudden cardiac death.Design: Retrospective analysis of the PCMA forms.Participants: Of the 32 national teams (with 23 players), PCMA forms from 605 players were submitted after the final match (82%). Data of 582 players were analyzed (79%).Main Outcome Measures: Recorded results of a standardized PCMA in all players before the 2006 FIFA World Cup including medical history, physical examination, resting/exercise electrocardiogram, and echocardiography were analyzed by 2 independent cardiologic reviewers.Results: Apart from general deficits in data quality, at least 6 players (1.0%) could be identified as demanding further investigations to rule out a serious cardiovascular disease.Conclusions: Comprehensive cardiac testing is feasible in international elite football. To improve future results, the PCMA was revised. It is questionable if exercise stress testing should be included in future PCMA. To ensure correct results, sports cardiologic expertise is essential. In the face of organizational challenges and variable medical standards, alternative approaches to the practical implementation of the PCMA need to be investigated. (Mikrofiche-Nummer: 17709)

3. Junge, A., Grimm, K., Feddermann, N. & Dvorak, J. (2009). Precompetition orthopedic Assessment of international elite football players (Orthopädische Vorwettkampf-Untersuchung internationaler Elite-Fußballer). Clin. J. Sport Med., 19 (4), 326-328. Zugriff am 10.09.2009 unter http://journals.lww.com/cjsportsmed/Abstract/2009/07000/Precompetition_Orthopedic_Assessment_of.11.aspx
   

   Objective: To assess the feasibility of the orthopedic part of a standardized precompetition medical assessment (PCMA) in teams from countries with variable medical background and to collect data on medical history and musculoskeletal findings of the players participating in the 2006 FIFA World Cup.Design: Retrospective analysis of the PCMA forms.Participants: Five hundred fifty-three players (75.1%) participating in the 2006 FIFA World Cup.Methods: The team physicians of participating teams were instructed to perform a specific standardized PCMA in all players before the 2006 FIFA World Cup. The orthopedic section included medical history and orthopedic examination of the lower extremity.Results: The completeness of the orthopedic section was in general very high, but the quality of recordings and examination technique differed among teams. About half of the players (51%) were reported to have sustained at least 1 severe football injury, with ligament/meniscus lesions of the knee and ligament injuries of the ankle being the most frequent diagnoses. Pathological findings on examination were rare.Conclusions: A standardized PCMA including comprehensive orthopedic examination is principally feasible in international elite football. The challenge is to ensure the quality of the physical examinations and to verify their predictive value. (Mikrofiche-Nummer: 17710)

4. Sutton, L., Scott, M., Wallace, J. & Reilly, T. (2009). Body composition of English Premier League soccer players: Influence of playing position, international status, and ethnicity (Körperbau von Fußballspielern der englischen Premier League: Einfluss von Spielposition, internationalem Status und Ethnie). J. Sports Sci., 27 (10), 1019-1026. Zugriff am 10.09.2009 unter http://www.informaworld.com/smpp/content~db=all~content=a914092011
   

   Body composition is a key consideration in the physical make-up of professional soccer players. The aims of the present study were to determine whether the body composition of professional soccer players varied according to playing position, international status or ethnicity, and to establish which variables best distinguished the soccer players from a reference group. Body composition was assessed using dual-energy X-ray absorptiometry in 64 male professional soccer players. Measured variables included bone mineral density and the relative amounts of lean and fat mass. Data were analysed using analysis of variance and stepwise discriminant function. The soccer players recorded better values than a reference group (n = 24) for all body composition compartments. Percent lean mass and bone mineral density were the variables best able to identify the soccer players (95.5% correctly classified). Differences in body composition were evident between goalkeepers and outfield players, but not between outfield playing positions. No differences were found on the basis of international status. The non-Caucasian players demonstrated significantly lower percent body fat (9.2 ± 2.0%) than the Caucasian players (10.7 ± 1.8%). It was concluded that body composition is important for elite soccer players, but that homogeneity between players at top professional clubs results in little variation between individuals.

Morphological differences of elite Croatian soccer players according to the team position (Morphologische Unterschiede von kroatischen Hochleistungsfußballern nach ihrer Spielposition).

   Team position is of extreme importance in interpretation of morphological data because there are specific demands for a specific play position. The aim of the study was the analysis of morphological characteristics and body composition of elite Croatian soccer players with respect to their team position. The measurements were performed on 57 soccer players, members of the First Croatian National League. The anthropometrical measurement encompassed 13 variables. Descriptive statistics, t-test and MANOVA were used in data processing. The goalkeepers were the tallest and the heaviest (182.9 4.3 cm; 80.1 5.1 kg), and had significantly higher amounts of body fat (20.2% goalkeepers vs. 13—15% others; p<0.05), whereas the forwards and the midfield players were on the average about 3 cm shorter. The goalkeepers had longer legs and arms (p<0.05), and the largest biacromial diameter (43.2 1.9 cm). The forwards were the shortest on the average (179.2 6.3 cm). The lowest values of fat tissue were found in defenders (13.9%) and midfield players (14.4%). In conclusion, the differences in morphological characteristics according to the team position were noticed only in goalkeepers, especially regarding their height, weight and the percentage of fat tissue.
