Previous research has reported that the gambler’s fallacy could be detected in goalkeepers’ behavior during penalty shootouts. Following repeated kicks in the same direction, goalkeepers were more likely to dive in the opposite direction on the next kick. We employ here a unique data collection approach and accurately measure the exact location of each ball when crossing the goal plane. This allows us to analyze how different definitions of the goal center width affect the results, and we show that this width indeed affects whether a gambler’s fallacy in goalkeepers’ diving behavior exists. We further augment the data with additional kicks from top international competitions and analyze the extended dataset. We also question whether previous treatments of kicking sequences adequately represent what goalkeepers consider as a run of consecutive kicks to the same side. A different representation of kicking sequences is provided and applied to the data. Overall, we find some evidence for the gambler’s fallacy after sequences of two or three kicks to the same side.

Frederick, Levis, Malliaris & Meyer (2018) report a package of laboratory studies where participants underestimate the value of “hedges”: Risky bets which cancel out the risk of another presently-held bet. However, it might be questioned to what extent laboratory findings predict field behavior. People might better understand hedges when more money is at stake, or when they have more time to reflect. We discuss three gamblers who, instead of hedging, used a costly “cash-out” option to eliminate the risk of their bets on Leicester FC’s improbable victory in the 2015/2016 English Premier League soccer season. The decision to cash-out rather than to hedge led to individual losses of up to £8,000, and did not seem plausibly explained by rational economic factors. High-stakes hedges are misunderstood too.

For an optimal performance, soccer players and referees need to consume a high-quality diet. The Healthy Eating Index (HEI) is a tool that can estimate diet quality and has been shown to be associated with body composition. The aims of the present study were first to determine the HEI-2015 score of the diets consumed by athletes and second its association with different body composition parameters of athletes. We conducted a cross-sectional study on 198 soccer players and referees. Dietary intakes were recorded using a validated food frequency questionnaire (FFQ), and HEI scores were calculated. Body composition parameters were measured using the bioelectrical impedance analysis. The mean score for the HEI-2015 was 65⋅04. A multiple linear regression model showed significant associations of the HEI-2015 score with percent body fat (PBF), percent muscle mass (PMM), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) in male soccer players aged <18 years, body mass index (BMI) in male soccer players aged ≥18 years and BMI and waist-to-height ratio (WHtR) in male soccer referees after adjustment for covariates (P < 0⋅05). The mean overall score for the HEI-2015 shows that Iranian soccer players and referees have an acceptable quality of diet. We also found significant associations between the HEI-2015 score and different body composition parameters in male soccer players and referees but we did not find any significant association in female athletes (P > 0⋅05).

Croatia’s monumental second-place finish at the 2018 FIFA World Cup represents the highest football achievement to date for the young nation. This victory, however, masks violent internal divisions between its domestic club football teams. This article examines the most salient rivalry between Dinamo Zagreb and Hajduk Split, two teams that have evolved to represent the interests of Croatia’s north and south, respectively. Using interviews with radical football fans, I argue that the two teams act as reservoirs for regional identity-building while violence between their fans is a microcosm for political and economic tensions between Zagreb and Split. More importantly, this rivalry exposes the dividedness of the Croatian state, as it continues to grapple with the complexity of its radical regional identities in the wake of its independence from Yugoslavia. This article contributes to the existing body of literature on sports identity and regionalisms/nationalism as well as how sporting teams shape the geographies of belonging.

This paper explores the effect of norms—standards of conduct dictated by an identity—on white, American immigration attitudes. Results from a survey experiment show that when respondents evaluate immigrants who violate cultural norms, by speaking a non-English language and/or rooting for a foreign soccer team, respondents are less supportive of green cards for immigrants. Moreover, norm violations are consequential for tolerant, prejudiced, liberal, moderate, and conservative respondents. Valuing cultural norms is a shared and pervasive aspect of immigration attitudes, and targeting norms for inquiry brings into view the societal structure of opposition to immigration. However, norm violations affect green card support among liberals only in evaluations of Latino immigrants, and among conservatives only in evaluations of European immigrants.

Objectives: The present study examined the relative contribution of recent or long-term heading to neuropsychological function in amateur adult soccer players. Participants and Methods: Soccer players completed a baseline questionnaire (HeadCount-12m) to ascertain heading during the prior 12 months (long-term heading, LTH) and an online questionnaire (HeadCount-2w) every 3 months to ascertain heading during the prior 2 weeks (recent heading, RH). Cogstate, a battery of six neuropsychological tests, was administered to assess neuropsychological function. Generalized estimating equations were used to test if LTH or RH was associated with neuropsychological function while accounting for the role of recognized concussion. Results: A total of 311 soccer players completed 630 HeadCount-2w. Participants had an average age of 26 years. Participants headed the ball a median of 611 times/year (mean=1,384.03) and 9.50 times/2 weeks (mean=34.17). High levels of RH were significantly associated with reduced performance on a task of psychomotor speed (p=.02), while high levels of LTH were significantly associated with poorer performance on tasks of verbal learning (p=.03) and verbal memory (p=.04). Significantly better attention (p=.02) was detectable at moderately high levels of RH, but not at the highest level of RH. One hundred and seven (34.4%) participants reported a lifetime history of concussion, but this was not related to neuropsychological function and did not modify the association of RH or LTH with neuropsychological function. Conclusion: High levels of both RH and LTH were associated with poorer neuropsychological function, but on different domains. The clinical manifestations following repetitive exposure to heading could change with chronicity of exposure. (JINS, 2018, 24, 147–155)

This experimental study with a controlled pre-test and post-test group design investigated the possible effects of four sessions of heading training on cognitive performance. A total of 118 participants (mean age of 22.25 years) were assigned to one of the three following groups: a heading-training group, a passing-training group and a waiting control group. The participants completed a cognitive test battery of attention (D2-test), working memory (Paced Auditory Serial Addition Task, PASAT-2) and visual spatial intelligence (Mental Rotation Test) tests before, immediately after the second training session and one week after the fourth training session. There were no between-group differences in cognitive performance after the second or the fourth heading training sessions. However, within the heading-training group, women complained more of headaches than men after the fourth training session. These results build on the results from the study of Rieder and Jansen (2011) that showed no neuropsychological consequences after one heading session, showing no cumulative effects of repeat heading.

In the first decades of the twentieth century, the inhabitants of greater Buenos Aires formed innumerable football clubs, as part of a burgeoning civic culture. Many of these clubs not only proved enduring but helped to shape the sense of neighbourhood that dominated much of the cultural and political world of the city. In this they differed from clubs in other South American cities, which tended to have much less of a barrio identity. However, successful soccer teams required assistance to acquire land and construct stadiums. The evidence of club records and the local press shows that as the clubs grew in size and importance, politicians and other leading neighbourhood figures became critical in obtaining the necessary resources for them, but in turn they made use of their association with the clubs to aid their election campaigns and build up their constituencies and clienteles.

Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season.

The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment. It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.

Based on the self-determination theory (Ryan & Deci, 2000), this study tested a model of the assumed sequential relationships between perceived autonomy support, psychological need satisfaction, self-determined motivation, and enjoyment/boredom. The hypothesized mediational roles of psychological need satisfaction and self-determined motivation were also studied. In a sample of 370 young male soccer players, path analysis results offered support for the proposed model. Total mediation was supported in the case of the psychological need satisfaction in the relationship between autonomy support and self-determined motivation, and partial mediation for self-determined motivation in the links between psychological need satisfaction and enjoyment (positive) and boredom (negative). Implications of autonomy-supportive behaviors provided by coaches for the quality of sport involvement among young athletes are discussed.

Introduction: The aim of this study was to describe the current state of disaster preparedness in hospitals in the public sector in the Western Cape, South Africa with the advent of the FIFA 2010 Soccer World Cup. The objectives included the completion of a self-reported assessment of readiness at all Western Cape public sector hospitals, to identify best practice and shortfalls in these facilities, as well as putting forward recommendations for improving disaster preparedness at these hospitals.

Methods: The National Department of Health, as part of the planning for the FIFA 2010 World Cup, appointed an expert committee to coordinate improvements in disaster medicine throughout the country. This workgroup developed a Self Reported Hospital Assessment Questionnaire, which was sent to all hospitals across the country. Data only were collected from public hospitals in the Western Cape and entered onto a purpose-built database. Basic descriptive statistics were calculated. Ethical approval was obtained from the Health Sciences Faculty Research Committee of the University of Cape Town.

Results: Twenty-seven of the 41 (68%) public hospitals provided completed data on disaster planning. The study was able to ascertain what infrastructure is available and what planning already has been implemented at these institutions.

Recommendations: Most hospitals in the Western Cape have a disaster plan for their facility. Certain areas need more focus and attention; these include: (1) increasing collaborative partnerships; (2) improving HAZMAT response resources; (3) specific plans for vulnerable populations; (4) contingency plans for communication failure; (5) visitor, media and VIP dedicated areas and personnel; (6) evacuation and surge capacity plans; and (7) increased attention to training and disaster plan exercises.

The concept of the “African Personality” was celebrated by the continent's first post-colonial President, Kwame Nkrumah. Sweeping to power in Ghana's first general election in 1951, Nkrumah and his Convention People's Party—inspired by Marcus Garvey and W. E. B. Du Bois—espoused the doctrines of nationhood and self-reliance. The conceptual dimensions of Nkrumah's “African Personality” and the role he had in mind for Association Football (soccer) as an instrument of its expression are crucial points of this analysis. Here we attempt to locate Nkrumah's political ideal within the contemporary realities of the migration of young Ghanaian soccer talent, examining at the same time the socio-economic processes which act as “push” and “pull” mechanisms in the context of such migratory trends. While Nkrumah's “race-conscious,” pan-African forces have been utilized in the face of post-colonial identifications, soccer loyalties and objectives which are far more immediate and parochial in character continue to supersede those surrounding national or “racial” interests. Ghana's domestic game and national selection are riven by ethnic and regional hostilities while interlopers from Europe—some acting alone, others as emissaries for European soccer clubs—have laid down roots in Ghana, recognizing the nation as a breeding ground for talented, and comparatively cheap, young soccer talent. We argue that such inveterate ethno-regional rivalries, along with the conditions of neoliberal capitalism and its instrumental system of uneven geographical development, have provided entry points for the post-colonial forces so maligned by Nkrumah. Furthermore, we question the wisdom of notions of belonging based on bounded units such as “race” and attendant expressions of “race-consciousness.”

Mass gatherings have a higher patient presentation rate than is found within the general population. Despite this fact, many mass gatherings are occurring without suitable medical coverage. South Africa has had no standard approach or model to determine the number of medical personnel needed to deploy to an event. The awarding of the FIFA (Federation International de Football Association) 2010 World Cup to South Africa has provided the impetus for the development of such a model. The model presented in this paper is based on existing recommendations that originate from the United Kingdom.

This paper outlines the modifications that have been made to this model to ensure that adequate medical resources still are provided, albeit in a developing country where medical resources may not be as plentiful.

This article considers the cultural adjustment of immigrants to Brazil through an analysis of the role that association football (soccer) played in identity formation in twentieth-century São Paulo. It focuses on the city's large Italian population, in particular the experiences of a leading club, the Società Sportiva Palestra Itália, and of the first generation of Brazilian footballers who migrated abroad in order to play football professionally, many of whom were Paulistas of Italian descent. It demonstrates that through football Italians obtained agency in negotiating the process by which they became Brazilian and found a means by which to preserve a sense of discrete ethnicity within São Paulo's multiethnic community.

There is increasing interest in the potential neuropsychological impact of sports-related concussion. A meta-analysis of the relevant literature was conducted to determine the impact of sports-related concussion across six cognitive domains. The analysis was based on 21 studies involving 790 cases of concussion and 2014 control cases. The overall effect of concussion (d = 0.49) was comparable to the effect found in the non-sports-related mild traumatic brain injury population (d = 0.54; Belanger et al., 2005). Using sports-concussed participants with a history of prior head injury appears to inflate the effect sizes associated with the current sports-related concussion. Acute effects (within 24 hr of injury) of concussion were greatest for delayed memory, memory acquisition, and global cognitive functioning (d = 1.00, 1.03, and 1.42, respectively). However, no residual neuropsychological impairments were found when testing was completed beyond 7 days postinjury. These findings were moderated by cognitive domain and comparison group (control group versus preconcussion self-control). Specifically, delayed memory in studies utilizing a control group remained problematic at 7 days. The implications and limitations of these findings are discussed. (JINS, 2005, 11, 345–357.)
