To date, despite a large body of evidence in favor of the advantage of an effect-related focus of attention compared with a movement-related focus of attention in motor control and learning, the role of vision in this context remains unclear. Therefore, in a golf-putting study, the relation between attentional focus and gaze behavior (in particular, quiet eye, or QE) was investigated. First, the advantage of an effect-related focus, as well as of a long QE duration, could be replicated. Furthermore, in the online-demanding task of golf putting, high performance was associated with later QE offsets. Most decisively, an interaction between attentional focus and gaze behavior was revealed in such a way that the efficiency of the QE selectively manifested under movement-related focus instructions. As these findings suggest neither additive effects nor a causal chain, an alternative hypothesis is introduced explaining positive QE effects by the inhibition of not-to-be parameterized movement variants.

In the current study we investigated whether ego depletion negatively affects attention regulation under pressure in sports by assessing participants' dart throwing performance and accompanying gaze behavior. According to the strength model of self-control, the most important aspect of self-control is attention regulation. Because higher levels of state anxiety are associated with impaired attention regulation, we chose a mixed design with ego depletion (yes vs. no) as between-subjects and anxiety level (high vs. low) as within-subjects factor. Participants performed a perceptual-motor task requiring selective attention, namely, dart throwing. In line with our expectations, depleted participants in the high-anxiety condition performed worse and displayed a shorter final fixation on bull's eye, demonstrating that when one's self-control strength is depleted, attention regulation under pressure cannot be maintained. This is the first study that directly supports the general assumption that ego depletion is a major factor in influencing attention regulation under pressure.

The goal of the present article is to introduce dual-process theories – in particular the default-interventionist model – as an overarching framework for attention-related research in sports. Dual-process theories propose that two different types of processing guide human behavior. Type 1 processing is independent of available working memory capacity (WMC), whereas Type 2 processing depends on available working memory capacity. We review the latest theoretical developments on dual-process theories and present evidence for the validity of dual-process theories from various domains. We demonstrate how existing sport psychology findings can be integrated within the dual-process framework. We illustrate how future sport psychology research might benefit from adopting the dual-process framework as a meta-theoretical framework by arguing that the complex interplay between Type 1 and Type 2 processing has to be taken into account in order to gain a more complete understanding of the dynamic nature of attentional processing during sport performance at varying levels of expertise. Finally, we demonstrate that sport psychology applications might benefit from the dual-process perspective as well: dual-process theories are able to predict which behaviors can be more successfully executed when relying on Type 1 processing and which behaviors benefit from Type 2 processing.

In the present study we investigated whether ego depletion negatively affects attention regulation under pressure in sports by assessing participants’ dart throwing performance and accompanying gaze behavior. According to the strength model of self-control the most important aspect of self-control is attention regulation (Schmeichel & Baumeister, 2010). As higher levels of state anxiety are associated with impaired attention regulation (Nieuwenhuys & Oudejans, 2012) we chose a mixed design with ego depletion (yes vs. no) as between-subjects and anxiety level (high vs. low) as within-subjects factor. A total of 28 right-handed students participated in our study (Mage = 23.4, SDage = 2.5; 10 female; no professional dart experience). Participants performed a perceptual-motor task requiring selective attention, namely, dart throwing. The task was performed while participants were positioned high and low on a climbing wall (i.e., with high and low levels of anxiety). In line with our expectations, a mixed-design ANOVA revealed that depleted participants in the high anxiety condition performed worse (p < .001) and displayed a shorter final fixation on bull’s eye (p < .01) than in the low anxiety condition, demonstrating that when one is depleted attention regulation under pressure cannot be maintained. This is the first study that directly supports the general assumption that ego depletion is a major factor in influencing attention regulation under pressure.

Sport participation means a privileged access to participate in the sport system and the opportunities of actual integration into sport (Seiberth et al., 2013). The access to sport activities is often restricted for female immigrants. The function of sport participation concerning exercise offers of social associations is not a common theme in research on migration or on sports-related integration. Research on boundaries (Lamont & Molnár, 2002) suggest that gender-related and ethnic boundaries are stable behavioural and cognitive patterns leading to unequal social opportunities. The present study examined the potential of a Swiss intercultural club regarding female immigrants’ integration into sport by focussing on gender-related and ethnic boundaries. Ten interviews with female immigrants and conductress of an intercultural club plus a group discussion were held. Using qualitative content analysis and documentary method, findings reveal multifaceted, interwoven boundaries, e.g. maternal devotion, exclusive exercise offers for women, language learning devotion, religious need of headscarf. Otherwise resources to overcome boundaries are provided: Deploying competent employees; offering childcare, exercise offers suited to mothers‘ time schedule and language lessons; equitable, on integration focussed club-life. Thus, intercultural clubs might help to overcome boundaries and facilitate access to exercise for female immigrants and integrate them more successfully into sport than many sport clubs. A boundary focus and present data may open new perspectives for sport organisation and integration research. Further investigations of social associations offering exercise are advised.

Regelmässiges körperliches Training induziert strukturelle, elektrische und funktionelle Anpassungen des Herzens. Die grösste Herausforderung für den Arzt liegt darin, Veränderungen hinweisend für eine strukturelle Herzerkrankung von physiologischen, trainingsassoziierten Anpassungen im Sinne eines 'Athlete's heart' zu unterscheiden. Bei zugrundliegender Kardiopathie ist sportliche Aktivität nicht die Ursache, sondern kann ein Trigger für belastungsabhängige Tachyarrhythmien bzw. für den belastungsabhängigen plötzlichen Herztod (SCD) sein. Um Athleten mit einer kardialen Grunderkrankung und erhöhtem Risiko für einen SCD frühzeitig zu identifizieren wird in Europa ein Preparticipation Screening empfohlen, welches von der Schweizerischen Gesellschaft für Sportmedizin (SGSM) übernommen wurde. Dieses Screening umfasst neben der spezifischen Anamnese und der Herzauskultation auch ein Ruhe-Elektrokardiogramm (Ruhe-EKG). Aufgrund der hohen Anzahl falsch-positiver EKG-Befunde wurden in den letzten Jahren die Beurteilungskriterien des Athleten-EKGs wiederholt angepasst, die Sensitivität und insbesondere auch die Spezifität konnte mit den „verfeinerten Seattle Kriterien“ 2014 deutlich verbessert werden. Der frühen Repolarisation galt in den letzten Jahren ein Hauptaugenmerk: neben dem (Ausdauer-) Training besteht eine klare Assoziation zum männlichen Geschlecht, zur Ethnie, zu den Veränderungen des vegetativen Nervensystems und zu erhöhten QRS-Voltage-Kriterien.

Synopsis: Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. Our study seeks to reveal and analyse the causes for professionalization processes in international sport federations, the forms resulting from it, as well as related consequences. Abstract: AIM OF ABSTRACT/PAPER - RESEARCH QUESTION Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. In this context, professionalization seems to have been adopted by sport organisations as an appropriate strategy to respond to pressures such as becoming more “business-like”. The ongoing study seeks to reveal and analyse the internal and external causes for professionalization processes in international sport federations, the forms resulting from it (e.g. organisational, managerial, economic) as well as related consequences on objectives, values, governance methods, performance management or again rationalisation. THEORETICAL BACKGROUND/LITERATURE REVIEW Studies on sport as specific non-profit sector mainly focus on the prospect of the “professionalization of individuals” (Thibault, Slack & Hinings, 1991), often within sport clubs (Thiel, Meier & Cachay, 2006) and national sport federations (Seippel, 2002) or on organisational change (Griginov & Sandanski, 2008; Slack & Hinings, 1987, 1992; Slack, 1985, 2001), thus leaving broader analysis on governance, management and professionalization in sport organisations an unaccomplished task. In order to further current research on above-mentioned topics, our intention is to analyse causes, forms and consequences of professionalisation processes in international sport federations. The social theory of action (Coleman, 1986; Esser, 1993) has been defined as appropriate theoretical framework, deriving in the following a multi-level framework for the analysis of sport organisations (Nagel, 2007). In light of the multi-level framework, sport federations are conceptualised as corporative actors whose objectives are defined and implemented with regard to the interests of member organisations (Heinemann, 2004) and/or other pressure groups. In order to understand social acting and social structures (Giddens 1984) of sport federations, two levels are in the focus of our analysis: the macro level examining the environment at large (political, social, economic systems etc.) and the meso level (Esser, 1999) examining organisational structures, actions and decisions of the federation’s headquarter as well as member organisations. METHODOLOGY, RESEARCH DESIGN AND DATA ANALYSIS The multi-level framework mentioned seeks to gather and analyse information on causes, forms and consequences of professionalization processes in sport federations. It is applied in a twofold approach: first an exploratory study based on nine semi-structured interviews with experts from umbrella sport organisations (IOC, WADA, ASOIF, AIOWF, etc.) as well as the analysis of related documents, relevant reports (IOC report 2000 on governance reform, Agenda 2020, etc.) and important moments of change in the Olympic Movement (Olympic revenue share, IOC evaluation criteria, etc.); and secondly several case studies. Whereas the exploratory study seeks more the causes for professionalization on an external, internal and headquarter level as depicted in the literature, the case studies rather focus on forms and consequences. Applying our conceptual framework, the analysis of forms is built around three dimensions: 1) Individuals (persons and positions), 2) Processes, structures (formalisation, specialisation), 3) Activities (strategic planning). With regard to consequences, we centre our attention on expectations of and relationships with stakeholders (e.g. cooperation with business partners), structure, culture and processes (e.g. governance models, performance), and expectations of and relationships with member organisations (e.g. centralisation vs. regionalisation). For the case studies, a mixed-method approach is applied to collect relevant data: questionnaires for rather quantitative data, interviews for rather qualitative data, as well as document and observatory analysis. RESULTS, DISCUSSION AND IMPLICATIONS/CONCLUSIONS With regard to causes of professionalization processes, we analyse the content of three different levels: 1. the external level, where the main pressure derives from financial resources (stakeholders, benefactors) and important turning points (scandals, media pressure, IOC requirements for Olympic sports); 2. the internal level, where pressure from member organisations turned out to be less decisive than assumed (little involvement of member organisations in decision-making); 3. the headquarter level, where specific economic models (World Cups, other international circuits, World Championships), and organisational structures (decision-making procedures, values, leadership) trigger or hinder a federation’s professionalization process. Based on our first analysis, an outline for an economic model is suggested, distinguishing four categories of IFs: “money-generating IFs” being rather based on commercialisation and strategic alliances; “classical Olympic IFs” being rather reactive and dependent on Olympic revenue; “classical non-Olympic IFs” being rather independent of the Olympic Movement; and “money-receiving IFs” being dependent on benefactors and having strong traditions and values. The results regarding forms and consequences will be outlined in the presentation. The first results from the two pilot studies will allow us to refine our conceptual framework for subsequent case studies, thus extending our data collection and developing fundamental conclusions.

Sport and Performance Psychology is an ever-evolving specialty. While its development continues, it has not been without its challenges. Sport and performance psychologists work in a variety of settings and often come from similar, yet inherently different, training backgrounds. Individuals from both sport sciences and psychology have made compelling arguments as to which approach provides quality services to their respective clients. The question that remains, however, is what are these quality services? Who are the clients and what do they need from professionals in the field?Collegiate student athletes inherently face a number of typical issues related to their age and development. They also face a number of atypical difficulties as a result of their status as student athletes. As such, they provide an adequate sample of potential presenting issues for sport and performance psychologists. This current study utilized a qualitative, exploratory method to evaluate the presenting issues that brought clients to seek services from professionals.This paper seeks to establish a foundation for the development of a theoretical basis of the psychology of human performance, including both performance and general mental health concerns, and how sport and performance psychologists can most effectively intervene in this process. This paper is based on an analysis of seven years of service delivery within a NCAA Division I athletic department.Results indicate that collegiate student athletes seek services related to performance enhancement and general mental health at relative equal frequency. As such, training and service delivery in both areas would be most beneficial and best serve this population.

From Introduction: Career transition issues have become of increasing interest in the field of sport psychology. Confronting the end of an athletic career is an inevitable reality that every athlete will confront in his or her lifetime (Baillie, 1993), regardless of level of competition (Kerr & Dacyshyn, 2000) or the amount of free choice related to the transition. Many athletes are able to cope with the effects of the transition process effectively, and see retirement as an opportunity to pursue new ventures and identity roles in life. However, retirement from sport can be an event that often results in various adjustment difficulties for an athlete involving emotional, social, financial, and vocational conflicts. Some athletes have reported experiencing effects such as depression, eating disorders, decreased self-esteem, increased suicidality, and substance abuse (Kerr and Dacyshyn, 2000). These types of distress can be exacerbated by the fact that many athletes fail to adequately anticipate and prepare for their impending transition (Baillie, 1993), and often embark on the retirement process without any formalized support (Stier, 2007).Typically, the role of a sport psychologist has been to assist in maximizing an athlete's competitive performance during the course of their career. However, as a sport psychologist's primary responsibility is to serve active competitors and athletic organizations, this tends to come at the expense of failing to provide follow-up care for the athlete as he or she retires from sport (Taylor, Ogilvie, and Lavallee, 2006). Since the 1970's, when the efforts of professionals in European sports organizations first received attention, there has been growing interest in academic circles about career transition

Background: Studies suggest that expert performance in sport is the result of long-term engagement in a highly specialized form of training termed deliberate practice. The relationship between accumulated deliberate practice and performance predicts that those who begin deliberate practice at a young age accumulate more practice hours over time and would, therefore, have a significant performance advantage. However, qualitative studies have shown that a large amount of sport-specific practice at a young age may lead to negative consequences, such as dropout, and is not necessarily the only path to expert performance in sport. Studies have yet to investigate the activity context, such as the amount of early sport participation, deliberate play and deliberate practice within which dropout occurs. Purpose: To determine whether the nature and amount of childhood-organized sport, deliberate play and deliberate practice participation influence athletes' subsequent decisions to drop out or invest in organized sport. It was hypothesized that young athletes who drop out will have sampled fewer sports, spent less time in deliberate play activities and spent more time in deliberate practice activities during childhood sport involvement. Participants: The parents of eight current, high-level, male, minor ice hockey players formed an active group. The parents of four high-level, male, minor ice hockey players who had recently withdrawn from competitive hockey formed a dropout group. Data collection: Parents completed a structured retrospective survey designed to assess their sons' involvement in organized sport, deliberate play and deliberate practice activities from ages 6 to 13. Data analysis: A complete data-set was available for ages 6 through 13, resulting in a longitudinal data-set spanning eight years. This eight-year range was divided into three levels of development corresponding to the players' progress through the youth ice hockey system. Level one encompassed ages 6–9, level two included ages 10–11 and level three covered ages 12–13. Descriptive statistics were used to report the ages at which the active and dropout players first engaged in select hockey activities. ANOVA with repeated measures across the three levels of development was used to compare the number of sports the active and dropout players were involved in outside of hockey, the number of hours spent in these sports, and involvement in various hockey-related activities. Findings: Results indicated that both the active and dropout players enjoyed a diverse and playful introduction to sport. Furthermore, the active and dropout players invested similar amounts of time in organized hockey games, organized hockey practices, specialized hockey training activities (e.g. hockey camps) and hockey play. However, analysis revealed that the dropout players began off-ice training at a younger age and invested significantly more hours/year in off-ice training at ages 12–13, indicating that engaging in off-ice training activities at a younger age may have negative implications for long-term ice hockey participation. Conclusion: These results are consistent with previous research that has found that early diversification does not hinder sport-specific skill development and it may, in fact, be preferable to early specialization. The active and dropout players differed in one important aspect of deliberate practice: off-ice training activities. The dropout players began off-ice training at a younger age, and participated in more off-ice training at ages 12 and 13 than their active counterparts. This indicates a form of early specialization and supports the postulate that early involvement in practice activities that are not enjoyable may ultimately undermine the intrinsic motivation to continue in sport. Youth sport programs should not focus on developing athletic fitness through intense and routine training, but rather on sport-specific practice, games and play activities that foster fun and enjoyment.

Superior recall of domain-specific patterns is well established as a defining attribute of expert performers. Recent studies on the developmental histories of expert team ball sport players (e.g. Baker, Côté, & Abernethy, 2003a) also suggest that experts characteristically receive exposure to a wide range of sports in their developing years and that this related sports experience may reduce the amount of sport-specific training needed to become an expert. This study examined whether the facilitation of expertise associated with other sport experience might arise from positive transfer of pattern recall skills from one sport to another. Expert netball, basketball and field hockey players and experienced non-experts performed a recall task for patterns of play derived from each of these sports. Experts from sports different to those shown in the presented pattern consistently outperformed non-experts in their recall of defensive player positions, suggesting some selective transfer of pattern recall skills may indeed be possible

The role of sport-specific practice in the development of decision-making expertise in the sports of field hockey, netball, and basketball was examined. Fifteen expert decision-makers and 13 experienced non-expert athletes provided detailed information about the quantity and type of sport-specific and other related practice activities they had undertaken throughout their careers. Experts accumulated more hours of sport-specific practice from age 12 years onwards than did non-experts, spending on average some 13 years and 4,000 hours on concentrated sport-specific practice before reaching international standard. A significant negative correlation existed between the number of additional activities undertaken and the hours of sportspecific training required before attaining expertise, suggesting a functional role for activities other than sport-specific training in the development of expert decision-making.

The purpose of the current study was to examine two different trajectories of sport participation and explore any similarities or differences that may result regarding per­sonal development and sport outcomes. Seventy-four youth athletes (40 “specializ­ers” and 34 “samplers”) were recruited for the current study and four measures were employed to assess sport experiences and outcomes. Discriminant function analyses revealed no differences between groups in asset possession or sources of enjoyment however, differences were reported in sport experiences and burnout. The “samplers” reported more experiences regarding the integration of sport and family as well as linkages to the community. Although the “specializers” reported higher levels of physical/emotional exhaustion than did the “samplers,” they also reported more expe­riences related to diverse peer groups. The differences highlight the importance of examining specific pathways of development in sport to gain a deeper understanding of youths’ experiences in sport.

The purpose of this study was to gain understanding of adolescents’ positive and negative developmental experiences in sport. Twenty-two purposefully sampled adolescent competitive swimmers participated in a semistructured qualitative interview. Content analysis led to the organization of meaning units into themes and categories (Patton, 2002). Athletes suggested their sport involvement facilitated many positive developmental experiences (i.e., related to challenge, meaningful adult and peer relationships, a sense of community, and other life experiences) and some negative developmental experiences (i.e., related to poor coach relationships, negative peer influences, parent pressure, and the challenging psychological environment of competitive sport). Findings underline the important roles of sport programmers, clubs, coaches, and parents in facilitating youths’ positive developmental experiences in sport, while highlighting numerous important directions for future research. Implications for coach training and practice are outlined.
