Statistics published by the German Football Association indicate that women are significantly under-represented amongst soccer coaches, especially in the amateur leagues. In this paper we analyse how gender stereotypes influence the structural conditions surrounding the recruitment of coaches to soccer clubs that contribute to the exclusion of women from coaching positions. A qualitative study of five selected soccer clubs which are members of a German regional soccer association reveals that informal and personal decision-making practices still play a fundamental role in the recruitment of coaches. These practices undermine formal guidelines and give disproportionate weight to stereotyped preferences in the recruitment of soccer coaches. In this context, decision-makers' (functionaries') professed support of women largely serves a symbolic purpose and creates an illusion of equality concerning decisions that have already been taken at an informal level.

Introduction: In professional soccer, talent selection relies on the subjective judgment of scouts and coaches. To date, little is known about coaches´ “eye for talent” (Christensen, 2009, p. 379) and the nature of the subjective criteria they use to identify those players with the greatest potential to achieve peak performance in adulthood (Williams & Reilly, 2000). Drawing on a constructivist approach (Kelly, 1991), this study explores coaches´ subjective talent criteria. It is assumed that coaches are able to verbalise and specify their talent criteria, and that these are related to their talent selection decisions based on instinct. Methods: Participants and generation of data. Five national youth soccer coaches (Mage = 55.6; SD = 5.03) were investigated at three appointments: (1) talent selection decision based on instinct, (2) semi-structured inductive interview to elicit each coaches´ talent criteria in detail, (3) communicative validation and evaluation of the players by each coach using the repertory grid technique (Fromm, 2004). Data Analysis: Interviews were transcribed and summarized with regard to each specified talent criterion. Each talent criterion was categorized using a bottom-up-approach (meaning categorization, Kvale, 1996). The repertory grid data was analysed using descriptive statistics and correlation analysis. Results and Discussion: For each coach, six to nine talent criteria were elicited and specified. The subjective talent criteria include aspects of personality, cognitive perceptual skills, motor abilities, development, technique, social environment and physical constitution, which shows that the coaches use a multi-dimensional concept of talent. However, more than half of all criteria describe personality characteristics, in particular achievement motivation, volition and self-confidence. In contrast to Morris (2000), this result shows that coaches have a differentiated view of the personality characteristics required to achieve peak performance. As an indication of criterion validity, moderate to high correlations (.57 ≤ r ≤ .81) are found between the evaluations of the players according to the coaches´ talent criteria and their talent selection decision. The study shows that coaches are able to specify their subject talent criteria and that those criteria are strongly related to their instinctive selection decisions. References: Christensen, M. K.

Einleitung Im Fußball entscheidet der Trainer, welche Spieler in eine Leistungsmannschaft selektioniert werden. Die Frage, nach welchen Kriterien Trainer die Spieler beurteilen und selektionieren, wurde bislang allerdings unzureichend untersucht (Williams & Reilly, 2000). In der vorliegenden qualitativen Studie wird der Frage nachgegangen, welche Talentkriterien aus Trainersicht für den späteren Erfolg im Spitzenfußball ausschlaggebend sind. Methode Interviewpartner waren sechs männliche Fußballtrainer (MAlter = 39.5; SD = 7.18), die hauptberuflich für die Nachwuchsabteilung (Altersklasse 13 – 17 Jahre) eines Schweizer Fußballvereins der höchsten nationalen Spielklasse (Super League) arbeiten und zum Zeitpunkt des Interviews mindestens die UEFA-A-Lizenz besaßen. Die Bestimmung der subjektiven Talentkriterien erfolgte mithilfe eines Interviewleitfadens, der sich an der Konstruktbestimmung der Repertory Grid Technik (vgl. Fromm, 2004) orientierte. Ausge-wertet wurden die Interviews mit einer qualitativen Inhaltsanalyse (Kvale, 1996). Ergebnisse und Diskussion Die Untersuchung zeigt, dass sich die subjektiven Talentkriterien von Trainern sprachlich differenziert erheben lassen. Die befragten Trainer formulierten jeweils sechs bis acht Talentkriterien, die Aspekte aus den Bereichen Persönlichkeit, kognitiv-perzeptuelle Fertigkeiten, konditionelle Fähigkeiten, Technik, physische Konstitution und Umfeld beinhalten. Dass einige Kriterien Aspekte mehrere dieser Bereiche beinhalten und inhaltlich nicht den Kriterien der anderen Trainer entsprechen, kann als Hinweis auf die Subjektivität und Individualität dieser Talentkriterien gedeutet werden. Beinahe die Hälfte der genannten Kriterien beinhalten Persönlichkeitsaspekte. Facetten der Leistungsmotivation wurden dabei am häufigsten genannt, gefolgt von Lernfähigkeit und Lernbereitschaft sowie anderen Aspekten wie z.B. zur Selbsteinschätzung und Zielorientierung. Die Er-gebnisse zeigen, dass die untersuchten Trainer eine differenzierte Wahrnehmung von entwicklungsförderlichen Persönlichkeitsmerkmalen haben. Die Bedeutung der Persönlichkeit aus Trainersicht für das Erreichen eines Spitzenniveaus ist vergleichbar mit den Ergebnissen vorheriger Untersuchungen (z.B. Christensen, 2009).

Recent data have suggested a relation among long-term endurance sport practice, left atrial remodeling, and atrial fibrillation. We investigated the influence of an increased vagal tone, represented by the early repolarization (ER) pattern, on diastolic function and left atrial size in professional soccer players. Fifty-four consecutive athletes underwent electrocardiography, echocardiography, and exercise testing as part of their preparticipation screening. Athletes were divided into 2 groups according to presence or absence of an ER pattern, defined as a ST-segment elevation at the J-point (STE) > or =0.1 mm in 2 leads. For linear comparisons average STE was calculated. Mean age was 24 +/- 4 years. Twenty-five athletes (46%) showed an ER pattern. Athletes with an ER pattern had a significant lower heart rate (54 +/- 9 vs 62 +/- 11 beats/min, p = 0.024), an increased E/e' ratio (6.1 +/- 1.2 vs 5.1 +/- 1.0, p = 0.002), and larger volumes of the left atrium (25.6 +/- 7.3 vs 21.8 +/- 5.0 ml/m(2), p = 0.031) compared to athletes without an ER pattern. There were no significant differences concerning maximum workload, left ventricular dimensions, and systolic function. Univariate regression analysis revealed significant correlations among age, STE, and left atrial volume. In a stepwise multivariate regression analysis age, STE and e' contributed independently to left atrial size (r = 0.659, p <0.001). In conclusion, athletes with an ER pattern had an increased E/e' ratio, reflecting a higher left atrial filling pressure, contributing to left atrial remodeling over time.

The objective of the present study was to measure the occurrence of orofacial and cerebral injuries in different sports and to survey the awareness of athletes and officials concerning the use of mouthguards during sport activities. Two hundred and sixty-seven professional athletes and 63 officials participating in soccer, handball, basketball and ice hockey were interviewed. The frequency of orofacial and cerebral trauma during sport practice was recorded and the reason for using and not using mouthguards was assessed. A great difference in orofacial and cerebral injuries was found when comparing the different kinds of sports and comparing athletes with or without mouthguards. 45% of the players had suffered injuries when not wearing mouthguards. Most injuries were found in ice hockey, (59%), whereas only 24% of the soccer players suffered injuries when not wearing mouthguards. Sixty-eight percentage of the players wearing mouthguards had never suffered any orofacial and cerebral injuries. Two hundred and twenty-four athletes (84%) did not use a mouthguard despite general acceptance by 150 athletes (56%). Although the awareness of mouthguards among officials was very high (59%), only 25% of them would support the funding of mouthguards and 5% would enforce regulations. Athletes as well as coaches should be informed about the high risk of oral injuries when performing contact sports. Doctors and dentists need to recommend a more intensive education of students in sports medicine and sports dentistry, and to increase their willingness to become a team dentist.

Aim: Increased rates of hospitalization due to cardiovascular events have been reported during phases of World Soccer Championships (WSC). The purpose of this pilot study was to explore acute psychological and physiological effects of watching a live broadcast soccer game during the WSC 2006. Methods: Seven male supporters (age: M=24; SD=2.7) of the Swiss National Soccer Team watched a game of their team in a controlled laboratory setting. Heart rate (HR), heart rate variability (HRV), salivary cortisol, alpha-amylase (sAA), and testosterone concentrations, as well as several mood ratings were captured repeatedly before, during, and after the game. Results: Subjects reported feeling stressed, and HR and sAA activity showed an increase during the game. In contrast, HRV, cortisol and testosterone were unaffected. Conclusion: Watching a sports competition seems to specifically affect the sympathetic nervous system, which can be measured by sensitive electrocardiographic and salivary markers.

OBJECTIVES: Although regular physical exercise clearly reduces cardiovascular morbidity risk, long-term endurance sports practice has been recognized as a risk factor for atrial fibrillation (AF). However, the mechanisms how endurance sports can lead to AF are not yet clear. The aim of our present study was to investigate the influence of long-term endurance training on vagal tone, atrial size, and inflammatory profile in professional elite soccer players. METHODS: A total of 25 professional major league soccer players (mean age 24+/-4 years) and 20 sedentary controls (mean age 26+/-3 years) were included in the study and consecutively examined. All subjects underwent a sports cardiology check-up with physical examination, electrocardiography, echocardiography, exercise testing on a bicycle ergometer, and laboratory analysis [standard laboratory and cytokine profile: interleukin (IL)-6, tumor necrosis factor (TNF)-alpha, IL-8, IL-10]. RESULTS: Athletes were divided into two groups according to presence or absence of an early repolarization (ER) pattern, defined as a ST-segment elevation at the J-point (STE) >/=0.1mm in 2 leads. Athletes with an ER pattern showed significantly lower heart rate and an increased E/e' ratio compared to athletes without an ER pattern. STE significantly correlated with E/e' ratio as well as with left atrial (LA) volume. The pro-inflammatory cytokines IL-6, IL-8, TNF-alpha as well as the anti-inflammatory cytokine IL-10 were significantly elevated in all soccer players. However, athletes with an ER pattern had significantly higher IL-6 plasma levels than athletes without ER pattern. Furthermore, athletes with "high" level IL-6 had significantly larger LA volumes than players with "low" level IL-6. CONCLUSIONS: Athletes with an ER pattern had significantly higher E/e' ratios, reflecting higher atrial filling pressures, higher LA volume, and higher IL-6 plasma levels. All these factors may contribute to atrial remodeling over time and thus increase the risk of AF in long-term endurance sports.
