Psychological assessment is a central component of applied sport psychology. Despite obvious and well-documented advantages of diagnostic online tools, there is a lack of a system for such tools for sport psychologists so far in Switzerland. Having the most frequently used questionnaires available online in one single tool for all listed Swiss sport psychologists would make the work of practitioners a lot easier and less time consuming. Therefore, the main goal of this project is to develop a diagnostic online tool system with the possibility to make available different questionnaires often used in sport psychology. Furthermore, we intend to survey status and use of this diagnostic online tool system and the questionnaires by Swiss sport psychologists. A specific challenge is to limit the access to qualified sport psychologists and to secure the confidentiality for the client. In particular, approved sport psychologists get an individual code for each of their athletes for the required questionnaire. With the help of this code, athletes can access the test via a secure website at any place of the world. As soon as they complete and submit the online questionnaire, analysed and interpreted data reach the sport psychologist via E-Mail, which is timesaving and easy applicable for the sport psychologist. Furthermore, data are available for interpretation with athletes and documentation of individual development over time is possible. Later on, completed and anonymised questionnaires will be collected and analysed. Bigger number of collected data give more insight in the psychometric properties, thus helping to improve and further develop the questionnaires. In this presentation, we demonstrate the tool and its feasibility using the German version of the Test of Performance Strategies (TOPS, Schmid et al., 2010). To conclude, this diagnostic online tool system offers new possibilities for sport psychologists working as practitioner.

Im deutschsprachigen Raum wird ein hoher Anteil an Migrantinnen, die sportlich inaktiv und in Sportvereinen unterrepräsentiert sind, konstatiert (Burrmann et al., 2015; Lamprecht et al., 2014). Migrantinnen ist der Zugang zu Sportaktivitäten häufig erschwert aufgrund von Diskriminierung, Konflikten und Grenzziehungsprozessen, denen Aspekte betreffend des Geschlechts und der Ethnizität inhärent sind. Vor diesem Hintergrund wurde bislang häufig das Potenzial der Integration in den Sport bzw. Sozialisation zum Sport von Migrantinnen in (ethnischen) Sportvereinen und im Schulsport untersucht. Wie jedoch die Integration in den Sport in interkulturellen Vereinen, welche Sportangebote offerieren, funktioniert, ist weder in der Migrations- noch in der sportbezogenen Integrationsforschung ein gängiges Thema. Basierend auf dem theoretischen Ansatz Boundary Work (Lamont & Molnár, 2002) untersucht die vorliegende Studie geschlechtsbezogene und ethnische Grenzziehungsprozesse hinsichtlich der Sportpartizipation von Migrantinnen in einem interkulturellen Verein sowie vereinsbezogene Möglichkeiten, welche die Integration in den Sport fördern. Es wurden halbstrukturierte Interviews mit acht Migrantinnen verschiedener Herkunft und zwei Leiterinnen eines interkulturellen Vereins in der deutschsprachigen Schweiz durchgeführt. Zusätzlich erfolgte eine Gruppendiskussion mit sechs Migrantinnen. Mittels qualitativer Inhaltsanalyse und dokumentarischer Methode wurden geschlechtsbezogene und ethnische Grenzen sowie Möglichkeiten für eine Sportpartizipation durch den Verein abgeleitet. Hinsichtlich der erschwerten Sportpartizipation indizieren die Resultate vielfältige, miteinander verschränkte, sich überlagernde und durchlässige Grenzen, die das Geschlecht und die Ethnizität allgemein betreffen. Im Speziellen wirken migrationsbedingt und lebensphasenspezifisch geprägte Haltungen gegenüber „mütterlichen“ Verpflichtungen, sprachlichen- und beruflichen Aus- bzw. Weiterbildungspflichten sowie Praktiken der Körperverhüllung. Die jeweilige Struktur der Grenzverschränkungen wirkt z.T. mehrfach restriktiv und prägt zugleich die verfügbare Zeit und finanzielle Mittel der Migrantinnen, was eine Dilemma artige Situation hervorruft. Zur Überwindung der Grenzen bietet der interkulturelle Verein insbesondere professionelle Mitarbeiterinnen; Kinderbetreuung; niederschwellige, kosten- und zeitgünstige Sportangebote exklusiv für Frauen; und eine wohlwollende Atmosphäre mit gleichberechtigtem Zusammensein. Interkulturelle Vereine können somit den Zugang zu Sportangeboten für Migrantinnen erleichtern und die Integration in den Sport bzw. die Sozialisation zum Sport fördern. Dies geschieht z.B. infolge bedarfsgerechter Vereinsangebote, unverbindlicher Teilnahmebedingungen und einer integrationsorientierten Vereinskultur. Der auf Grenzziehung fokussierte theoretische Ansatz und die vorliegenden Resultate eröffnen neue Forschungsperspektiven im Bereich Sport und Sozialisation sowie Integration.

In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

I september 2014 bytte Leeds Metropolitan University, trots studentprotester, namn till Leeds Beckett University; universitetets första colleges låg i Beckett Park, vilken i sin tur fått namn efter bankiren och konservative parlamentsledamoten Ernest Beckett, 2nd Baron Grimthorpe (1856–1917), vars alma mater faktiskt var Trinity College, Cambridge. Leeds-studenternas motstånd hade sin grund i att namnändringen beräknades kosta en kvarts miljon pund, alltmedan inte minst universitetets idrottsanläggningar tillåtits förfalla. Vi vet inte hur universitetets personal ställde sig till namnförändringen, och särskilt nyfikna är vi ju på vad professorn i Leisure Studies (fritidsforskning, fritidsvetenskap) vid Leeds Beckett University, Karl Spracklen, tyckte om förändringen. Detta är dock blott "idle curiosity"; Spracklen är aktuell av ett helt annat, och viktigare, skäl, nämligen för sin bok Leisure, Sports & Society (Palgrave Macmillan). Spracklen, som är sociolog och vars forskningsintresse också inkluderar "metal music" (som sekreterare för International Society for Metal Music Studies och redaktör för Metal Music Studies) och "whiskey tourism" (som drivande i British Sociological Associations Alcohol Study Group) är en centralfigur inom det brittiska fritidsforskningsetablissemanget – han har bland annat varit ordförande i viktiga LSA, Leisure Studies Association från 2009 till 2013. Han har därtill en lång rad publikationer bakom sig, böcker, antologibidrag och vetenskapliga artiklar inom idrotts- och fritidsforskning i vid mening. Den nya boken ges här en grundlig recension av Erik Backman, som ju vet ett och annat om fritidsforskning, Spracklen bottnar teoretiskt i Habermas, i sig ovanligt bland brittiska forskare, men också i Marx, Weber och Bourdieu, bland andra, i sin utforskning av sambandet mellan fritid, fysisk aktivitet och sport ur ett tvärvetenskapligt perspektiv som innefattar idrottsvetenskap, sociologi, cultural studies, historia, filosofi och psykologi. Och vår recensent är imponerad över bredden, djupet och ambitionsnivån – även om det kan bli lite tjatigt från och till.

BACKGROUND: An increased prevalence of risky alcohol consumption and alcohol-related harm has been reported for members of sporting groups and at sporting venues compared with non-sporting populations. While sports clubs and venues represent opportune settings to implement strategies to reduce such risks, no controlled trials have been reported. The purpose of the study was to examine the effectiveness of an alcohol management intervention in reducing risky alcohol consumption and the risk of alcohol-related harm among community football club members.

METHOD: A cluster randomised controlled trial of an alcohol management intervention was undertaken with non-elite, community football clubs and their members in New South Wales, Australia. Risky alcohol consumption (5+ drinks) at the club and risk of alcohol-related harm using the Alcohol Use Disorders Identification Test (AUDIT) were measured at baseline and postintervention.

RESULTS: Eighty-eight clubs participated in the trial (n=43, INTERVENTION; n=45, CONTROL) and separate cross-sectional samples of club members completed the baseline (N=1411) and postintervention (N=1143) surveys. Postintervention, a significantly lower proportion of intervention club members reported: risky alcohol consumption at the club ( INTERVENTION: 19%; CONTROL: 24%; OR: 0.63 (95% CI 0.40 to 1.00); p=0.05); risk of alcohol-related harm ( INTERVENTION: 38%; CONTROL: 45%; OR: 0.58 (95% CI 0.38 to 0.87); p<0.01); alcohol consumption risk ( INTERVENTION: 47%; CONTROL: 55%; OR: 0.60 (95% CI 0.41 to 0.87); p<0.01) and possible alcohol dependence ( INTERVENTION: 1%; CONTROL: 4%; OR: 0.20 (95% CI 0.06 to 0.65); p<0.01).

CONCLUSIONS: With large numbers of people worldwide playing, watching and sports officiating, enhancing club-based alcohol management interventions could make a substantial contribution to reducing the burden of alcohol misuse in communities.

The purpose of this study was to examine the validity and reliability of the Portuguese version of the Rudd Stoll Beller Hahm Value-judgement Inventory (RSBHVI) in a sample of adolescents. The RSBHVI, which measures moral and social reasoning, was translated using a back translation method. A sample of 238 10th to 12th grade high school students (age mean value 16.93 years, s = 1.34) completed the Portuguese versions of RSBH, and the Task and Ego-orientation Questionnaire. Partial support for the original structure of the moral reasoning scale, but not the social reasoning scale, was found. Females, and non-athletes and individual sport athletes scored significantly higher than males and team sport athletes in moral reasoning, respectively. Moral reasoning was negatively correlated with ego-orientation (r = −30; p <. 001) and uncorrelated with task-orientation (r = .10, p > .05). Participants who were low-ego scored higher in moral reasoning than those who were high-ego. It is suggested that decreasing levels of ego-orientation may be necessary to improve athletes’ moral reasoning.

Recent data indicate that levels of overweight and obesity are increasing at an alarming rate throughout the world. At a population level (and commonly to assess individual health risk), the prevalence of overweight and obesity is calculated using cut-offs of the Body Mass Index (BMI) derived from height and weight. Similarly, the BMI is also used to classify individuals and to provide a notional indication of potential health risk. It is likely that epidemiologic surveys that are reliant on BMI as a measure of adiposity will overestimate the number of individuals in the overweight (and slightly obese) categories. This tendency to misclassify individuals may be more pronounced in athletic populations or groups in which the proportion of more active individuals is higher. This differential is most pronounced in sports where it is advantageous to have a high BMI (but not necessarily high fatness). To illustrate this point we calculated the BMIs of international professional rugby players from the four teams involved in the semi-finals of the 2003 Rugby Union World Cup. According to the World Health Organisation (WHO) cut-offs for BMI, approximately 65% of the players were classified as overweight and approximately 25% as obese. These findings demonstrate that a high BMI is commonplace (and a potentially desirable attribute for sport performance) in professional rugby players. An unanswered question is what proportion of the wider population, classified as overweight (or obese) according to the BMI, is misclassified according to both fatness and health risk? It is evident that being overweight should not be an obstacle to a physically active lifestyle. Similarly, a reliance on BMI alone may misclassify a number of individuals who might otherwise have been automatically considered fat and/or unfit.

Team games conceptualized as dynamical systems engender a view of emergent decision-making behaviour under constraints, although specific effects of instructional and body-scaling constraints have yet to be verified empirically. For this purpose, we studied the effects of task and individual constraints on decision-making processes in basketball. Eleven experienced female players performed 350 trials in 1 vs. 1 sub-phases of basketball in which an attacker tried to perturb the stable state of a dyad formed with a defender (i.e. break the symmetry). In Experiment 1, specific instructions (neutral, risk taking or conservative) were manipulated to observe effects on emergent behaviour of the dyadic system. When attacking players were given conservative instructions, time to cross court mid-line and variability of the attacker's trajectory were significantly greater. In Experiment 2, body-scaling of participants was manipulated by creating dyads with different height relations. When attackers were considerably taller than defenders, there were fewer occurrences of symmetry-breaking. When attackers were considerably shorter than defenders, time to cross court mid-line was significantly shorter than when dyads were composed of athletes of similar height or when attackers were considerably taller than defenders. The data exemplify how interacting task and individual constraints can influence emergent decision-making processes in team ball games.

INTRODUCTION In their target article, Yuri Hanin and Muza Hanina outlined a novel multidisciplinary approach to performance optimisation for sport psychologists called the Identification-Control-Correction (ICC) programme. According to the authors, this empirically-verified, psycho-pedagogical strategy is designed to improve the quality of coaching and consistency of performance in highly skilled athletes and involves a number of steps including: (i) identifying and increasing self-awareness of ‘optimal’ and ‘non-optimal’ movement patterns for individual athletes; (ii) learning to deliberately control the process of task execution; and iii), correcting habitual and random errors and managing radical changes of movement patterns. Although no specific examples were provided, the ICC programme has apparently been successful in enhancing the performance of Olympic-level athletes. In this commentary, we address what we consider to be some important issues arising from the target article. We specifically focus attention on the contentious topic of optimization in neurobiological movement systems, the role of constraints in shaping emergent movement patterns and the functional role of movement variability in producing stable performance outcomes. In our view, the target article and, indeed, the proposed ICC programme, would benefit from a dynamical systems theoretical backdrop rather than the cognitive scientific approach that appears to be advocated. Although Hanin and Hanina made reference to, and attempted to integrate, constructs typically associated with dynamical systems theoretical accounts of motor control and learning (e.g., Bernstein’s problem, movement variability, etc.), these ideas required more detailed elaboration, which we provide in this commentary.

An understanding of physical growth and maturation is relevant to many disciplines, including exercise and sport science, anthropology, human biology, medicine, psychology and education. Growth and maturation is governed by a complex interaction between genetic and environmental factors. There is increasing evidence that physical activity plays an important role in normal growth, development, health and well-being of children and youth, however, caution is required in the activity setting so that growth and maturation is not jeopardised. To appreciate the impact of physical activity and/or exercise on growth and maturation, a thorough understanding of the general principles of auxology is useful. Following an introduction to terminology, an overview of physical growth and development is provided in the context of morphological changes. Detailed information is provided regarding individual variability in growth and development along with sexual dimorphism. A small degree of sexual dimorphism exists at birth however striking differences develop during the pubertal years. Sexual dimorphism in body composition is largely regulated by endocrine factors with critical roles played by growth hormone and gonadal steroids.

The role of ecological constraints on the acquisition of sport expertise is gaining attention in sport science, although more research is needed. In this position paper we provide an ecological explanation for expertise acquisition, as alluding to qualitative data that support the idea that unconventional, even aversive, environmental constraints may play an important role in the development of world-class athletes. We exemplify this argument by profiling the role of unconventional practice environments using association football in Brazilian society as a task vehicle. Contrary to the traditional idea that only deliberate training and development programmes can lead to the evolution of expertise, we propose how expert performance might be gained through highly unstructured activities in Brazilian football, that represent a powerful and little understood implicit environmental constraint that can lead to expertise development in sport.

Evasive change-of-direction manoeuvres (agility skills) are a fundamental ability in rugby union. In this study, we explored the attributes of agility skill execution as they relate to effective attacking strategies in rugby union. Seven Super 14 games were coded using variables that assessed team patterns and individual movement characteristics during attacking ball carries. The results indicated that tackle-breaks are a key determinant of try-scoring ability and team success in rugby union. The ability of the attacking ball carrier to receive the ball at high speed with at least two body lengths from the defence line against an isolated defender promoted tackle-breaks. Furthermore, the execution of a side-step evasive manoeuvre at a change of direction angle of 20–60° and a distance of one to two body lengths from the defence, and then straightening the running line following the initial direction change at an angle of 20–60°, was associated with tackle-breaks. This study provides critical insight regarding the attributes of agility skill execution that are associated with effective ball carries in rugby union.
