Precompetition cardiac assessment of football players participating in the 2006 FIFA World Cup Germany

Professional footballers have a limited understanding of the precompetition medical assessment and the possible outcomes including disqualification: a cross-sectional survey

Objectives

To determine professional footballers’ level of understanding of the purpose of the precompetition medical assessment (PCMA) and to evaluate their knowledge of potential outcomes following a PCMA, including disqualification.

Methods

Professional footballers from the Australasian A-League and Westfield W-League were asked to complete a 25-question survey. The relationship between dichotomised outcomes and explanatory variables was analysed with multivariate logistic regression; p<0.05 was considered statistically significant.

Results

A total of 212 players participated (response rate=48.8%). Most respondents selected ‘To detect medical conditions that may affect performance’ and ‘To detect current injuries’ (n=137, 64.6%; n=130, 61.3%) as the purpose of a PCMA. Approximately one-third (n=74, 38.1%) were neutral or believed that a normal PCMA prevented cardiac arrest. Receiving more PCMAs (p<0.0003) and receiving an explanation during their PCMA (p=0.0175) led to greater awareness of the assessment’s limitations. Most participants did not know the definitions of syncope (n=181, 93.3%) or Marfan syndrome (n=183, 94.3%). Fifty players (28.1%) did not know that disqualification was a possible outcome of a PCMA, and younger players were less aware of this possible outcome (p=0.0216).

Conclusion

Professional footballers appear to have a limited understanding of the purpose of a PCMA, emphasising the musculoskeletal system and performance. They also appear unfamiliar with the components of the PCMA and medical terms. Finally, many are unaware that disqualification can result from an abnormal PCMA. Player health knowledge must be improved; the informed consent process appears an ideal time to provide this education.

Cardiovascular pre-participation screening in young athletes: Recommendations of the Association of European Paediatric Cardiology

Sudden death in young competitive athletes can be avoided by implementation of pre-participation screening programmes. A screening programme should be performed only by trained physicians and should include the athlete's personal and family history, physical examination results, and the readings from a 12-lead-electrocardiogram. The athlete should undergo this screening programme every second year to detect progressive diseases. In addition, the programme should include detailed instructions to the athletes to pause training during infections in order to prevent sudden death due to myocarditis.

Left Atrium Size in Elite Athletes

OBJECTIVES

The goal of this study was to perform a meta-analysis of the published literature to investigate the relationship of high levels of exercise training to left atrial (LA) size.

BACKGROUND

The "athlete's heart" is a series of cardiac adaptations to systematic exercise training and may include LA enlargement.

METHODS

We conducted a systematic review of English-language studies in MEDLINE and Scopus from inception through April 29, 2014, that reported LA size in elite athletes.

RESULTS

A total of 54 studies comprising 7,189 elite athletes and 1,375 controls were included. Forty-eight of the 54 studies reported absolute LA diameter in 7,018 athletes and 1,044 controls. Nine of the 54 studies (including 992 athletes and 426 controls) presented LA volume corrected for body surface area. The adjusted weighted mean LA diameter was 4.1 mm greater in athletes overall compared with sedentary controls (p < 0.0001), and LA volume index was 7.0 ml/m(2) greater in athletes than controls (p < 0.01). Compared with controls, LA diameter was 4.6 mm greater in endurance-trained athletes (p < 0.0001), 2.9 mm greater in strength-trained athletes (p < 0.03), 3.5 mm greater in combined strength- and endurance-trained athletes (p < 0.0001), and 4.2 mm greater in athletes with unspecified training (p < 0.02).

CONCLUSIONS

To our knowledge, this is the largest compilation of studies documenting that elite athletes have larger LA dimensions compared with controls when evaluated by either LA diameter or LA volume corrected for body surface area. The largest average LA diameters were reported in endurance athletes. Physicians evaluating athletes should be aware that the LA is increased in both strength- and endurance-trained elite athletes.

Pre-participation and follow-up screening of athletes for endurance sport

Physical activity increases life expectancy and sport is a priori not harmful. Exhausted sporting activity (e.g. endurance running, triathlon, cycling or competitive sport) can lead under individual conditions to negative cardiac remodelling (pathological enlargement/function of cardiac cavities/structures) or in worst case to cardiac arrhythmias and sudden cardiac death (SCD). This individually disposition can be genetically determined or behaviourally/environmentally acquired. Overall competitive young male athletes suffer five-fold higher than non-competitive athletes from sudden death and athletes aged over 30 bear a potential for arrhythmias, atrial fibrillation or a 20-fold higher possibility for SCD as female athletes. Patients with diabetes, coronary disease, obesity or hypertension require different special managements. Screening of cardiorespiratory health for sport activities has a lot of faces. Basically there is a need for indicated examinations or possible preventive measures inside or outside of pre-competition screening. The costs of screening compared to expenditure of whole effort for sporting activities are acceptable or even negligible, but of course dependent on national/regional settings. The various causes and possibilities of screening will be discussed in this article as basic suggestion for an open discussion beyond national borders and settings.

Sudden cardiac death in the soccer field: a retrospective study in young soccer players from 2000 to 2013

Soccer is the most popular sport in the world, with over 200 million active players. Sudden cardiac death (SCD) represents the most striking as well as the most common cause of death in the soccer field. Underlying cardiovascular pathologies predispose to life threatening ventricular arrhythmias and SCD in soccer players. Up to thousands to hundred thousands players might have an underlying condition that predisposes them for SCD. After several media striking SCD events in soccer players the Fédération Internationale de Football Association (FIFA) has made screening recommendations that are more thorough than the ones recommended for the American Heart Association and the European Society of Cardiology. We present a retrospective search through Internet databases that resulted in 54 soccer players with SCD events from 2000 until 2013. In this article, we will describe and discuss the conditions of those cases of SCD in order to provide more knowledge of the factors that may precipitate SCD in young soccer players.

A Meta-Analysis of Aortic Root Size in Elite Athletes

Background—

The aorta is exposed to hemodynamic stress during exercise, but whether or not the aorta is larger in athletes is not clear. We performed a systematic literature review and meta-analysis to examine whethere athletes demonstrate increased aortic root dimensions compared with nonathlete controls.

Methods and Results—

We searched MEDLINE and Scopus from inception through August 12, 2012, for English-language studies reporting the aortic root size in elite athletes. Two investigators independently extracted athlete and study characteristics. A multivariate linear mixed model was used to conduct meta-regression analyses. We identified 71 studies reporting aortic root dimensions in 8564 unique athletes, but only 23 of these studies met our criteria by reporting aortic root dimensions at the aortic valve annulus or sinus of Valsalva in elite athletes (n=5580). Athletes were compared directly with controls (n=727) in 13 studies. On meta-regression, the weighted mean aortic root diameter measured at the sinuses of Valsalva was 3.2 mm ( P =0.02) larger in athletes than in the nonathletic controls, whereas aortic root size at the aortic valve annulus was 1.6 mm ( P =0.04) greater in athletes than in controls.

Conclusions—

Elite athletes have a small but significantly larger aortic root diameter at the sinuses of Valsalva and aortic valve annulus, but this difference is minor and clinically insignificant. Clinicians evaluating athletes should know that marked aortic root dilatation likely represents a pathological process and not a physiological adaptation to exercise.

Risk management: FIFA's approach for protecting the health of football players

BACKGROUND

Sport and exercise have long-term health benefits, but there is also a risk that participants will sustain injuries and/or ill health from these activities. For this reason, international sports governing bodies have a responsibility to identify the risks that exist within their sport and to provide guidance to participants and other stakeholders on how these risks can be controlled within acceptable levels.

PURPOSE

To demonstrate how Fédération Internationale de Football Association (FIFA), as football's governing body, uses a risk management framework to identify, quantify, mitigate and communicate the risks of injury and ill health in football for men, women and children in all environments.

METHOD

All the research papers published by FIFA's Medical Assessment and Research Centre (F-MARC) during the period 1994 to 2011 were reviewed and categorised according to an established sport-related risk management framework.

CONCLUSIONS

F-MARC investigated and mitigated 17 areas of risk to footballers' health in a coherent and consistent approach through the process of risk management.

Pre-competition cardiac screening in professional handball players - setting up at the EHF European Handball Championship 2010 in Austria

In many sports, regular cardiac screening for exercise-associated sudden cardiac death is still not provided. To set up the current situation in top-skilled handball players qualified for the 2010 European Handball Championship in Austria, a standardised questionnaire was sent to every team. The fact that only 42.7% of the players returned the questionnaire may lead to the conclusion that the awareness of the problem is quite low. However, 82% of these players have been screened according to current recommendations. Half of the teams were screened inhomogeneously: 5 players (4.1%) have not been screened within the last years, 1 athlete (0.8%) was screened without an ECG. While 69% of the athletes got their first screening only after the age of 18, 16 players (13.1%) never went through a specific screening ever. We identified 17 athletes (13.9%) with a highly suspicious history, 2 of them (1.6%) never underwent a medical screening at all.

Development and implementation of a standardized precompetition medical assessment of international elite football players--2006 FIFA World Cup Germany

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.
