Objectives: The present research investigates how coaches’ identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches’ identity leadership would be associated with players’ perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches’ identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players’ strength of team identification.Design: We conduced a cross-sectional study of male soccer players in Germany.Method: The final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches’ identity leadership, team identification, team effort, turnover intentions, and individual/team performance.Results: Analysis revealed a positive relationship between coaches’ identity leadership and team effort, as well as individual and team performance. Moreover, coaches’ identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.Conclusions: These findings support claims that coaches’ identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead.

Purpose Drawing on existing theory, a model is developed to illustrate how the interaction between leaders and followers similarity in narcissism and goal congruence may influence subgroup formation in teams, and how this interaction influences team identification and team performance. Design/methodology/approach The proposed model draws on dominance complementary, similarity attraction, faultline formation and trait activation theories. Findings Leader–follower similarity in narcissism and goal congruence may stimulate subgroup formation, possibly resulting in conformers, conspirators, outsiders and victims, especially when performance pressure on a team is high. Followers who are low in narcissism and share goals with a leader who is narcissistic are likely to become conformers. Followers who are high in narcissism and share goals with a narcissistic leader are likely to become confederates. Followers who do not share goals with a narcissistic leader will be treated by the leader and other members as outsiders if they are high in narcissism, and victimized if they are low in narcissism. In addition, the emergence of these subgroups leads to reduced team identification and lower team performance. Practical implications Higher level managers, coaches and human resource professions can assess and, if necessary, counteract low team identification and performance resulting from the narcissistic personality characteristics of leaders and followers. Originality/value The model addresses how and under what conditions narcissistic leaders and followers may influence subgroup formation and team outcomes.

And Performance

Purpose This study aims to focus on relational social capital in family wineries. Relational social capital is influenced by the family nature of the business and is at the same time a key antecedent of winery performance. The aim is to analyse these relationships in the qualified denomination of origin (DOC) Rioja wine industry (Spain). Design/methodology/approach Using a final sample of 110 family wineries, a Baron and Kenny approach was performed to investigate the causal and mediating relationships between the generation in control, relational social capital and family winery performance. Findings Using a final sample of 110 family wineries, the study demonstrates that later generations show a higher level of relational social capital, that the positive relationship between relational social capital and performance is maintained in a family firm sample and that the generation in control sequentially influence on performance through its influence on relational social capital. Research limitations/implications The main limitations are that empirical data were obtained only from DOC Rioja wine family businesses and a cross-sectional study was conducted. Social implications This study provides policymakers and family managers responsible for succession with a better understanding of the effects of transferring the business to the next generations in terms of relational social capital and performance. Originality/value To the best of the knowledge, this is the first study to examine the sequential relationships between generation, relational social capital and performance in DOC Rioja family wineries. The context of the DOC Rioja wine industry is particularly noteworthy for two reasons. First, in this industry, family-controlled firms predominate. Second, the DOC Rioja wine industry is focussed on the small-to-medium context, which has conventionally provided a very good area for the development of social capital theory.

ABSTRACT Introduction: Soccer is the most popular sport in Brazil and worldwide, but there is insufficient data on the eye health of soccer players, and eye conditions may affect the well-being and performance of these athletes. Objective: To perform an ocular evaluation of a representative sample of professional soccer players from Brazil. Methods: This was a cross-sectional study conducted over four consecutive years (2009-2012) at a single professional soccer club in Brazil. The ophthalmology evaluation was performed by the same ophthalmologist in each sample. Prior to the ophthalmology evaluation, all participants filled out a questionnaire to provide the following demographic data: age, position, use of contact lenses or ophthalmic drugs, symptoms, previous ocular surgery, and date of the last ophthalmology evaluation. Visual acuity, intraocular pressure (IOP) and color vision were tested during the ophthalmologic examination, and ophthalmoscopy and biomicroscopy exams were performed. Results: One hundred and twenty bilateral ophthalmology evaluations were performed in 84 professional soccer players between 2009 and 2012. Pinguecula and pterygium were the most common conditions found in the athletes’ biomicroscopy exams, corresponding to 63% (38/60) and 17% (10/60) of abnormalities, respectively. In the contrast sensitivity evaluation, only one athlete was color blind. No significant associations were found between the position of the athlete and the results of the biomicroscopy and ophthalmoscopy exams. Conclusion: Despite the high prevalence of abnormalities found in the ophthalmology evaluation, most refractive abnormalities did not require correction, and the biomicroscopy abnormalities were mostly benign.

Background: Soccer is played by many children younger than 12 years. Despite its health benefits, soccer has also been linked to a high number of sport-related injuries. Purpose: To investigate the relationship between clinical factors and knee or heel pain in youth soccer players. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Study participants included 602 soccer players aged 8 to 12 years who were asked whether they had experienced episodes of knee or heel pain. Data were collected on age, body mass index, years of playing soccer, playing position, and training hours per week. Associations of clinical factors with the prevalence of knee or heel pain were examined by univariate and multivariate logistic regression analyses. Results: Episodes of knee and heel pain were reported by 29.4% and 31.1% of players, respectively. Multivariate analyses revealed that older age and more years of playing soccer were significantly and positively associated with the prevalence of knee pain ( P = .037 and P = .015 for trend, respectively) but did not identify any significant associations for heel pain. Conclusion: In this study of youth soccer players, knee pain was associated with older age and more years of play, but heel pain was not significantly associated with any factor.

Introduction. PEF has never been characterized among healthy Moroccan adults. The objective of this study is to describe the values of PEF among healthy Moroccan adults, to study its relationship with anthropometric parameters (gender, age, height, and weight), to compare spirometric and flowmetric PEF, to establish the prediction equations for PEF, and to study the correlation between PEF and FEV1. Methods. Cross-sectional study conducted between May and June 2016. It involved healthy nonsmoking volunteers living in Tetouan, Morocco, gathered through a mobile stand realization of spirometry and peak flow measurements. Results. Our final sample concerned 313 adults (143 men and 170 women). For both men and women, age and height were the main determinants of PEF, and a positive correlation was found between PEF and FEV1. Conclusion. Our study has established the PEF predictive equations in the Moroccan adult population. Our results allow us to conclude that the PEF can be a reliable alternative of FEV1 in centers not equipped with spirometry.

Nutrition education is one of the factors that may help to promote behavior change and therefore may improve the dietary habits of adolescent soccer players. However, information about the relationship between nutrition knowledge (NK) and the dietary behavior of these athletes is scarce. The purpose of this study was to evaluate the eating habits of adolescent soccer players and analyse the correlations among dietary intake and NK. Seventy-three Brazilian adolescent soccer players (aged 14–19 years), from four professional clubs, underwent anthropometric evaluation and completed 3-day food records. Misreporting of energy intake was evaluated and the dietary intake data were energy-adjusted and compared with recommendations for athletes and dietary reference intakes. The athletes also answered a questionnaire about barriers for healthy eating and a nutrition knowledge test divided into three sections: Basic Nutrition Knowledge (BNK), Sports Nutrition Knowledge (SNK), and Food Pyramid Nutrition Knowledge (FPNK). The participants showed a low NK (54.6%) and an inadequate intake of fruits, vegetables, dairy, carbohydrates, and micronutrients. A positive correlation was found between the ingestion of phosphorus and FPNK as well as among calcium and both SNK and Total NK (p<0.05). Sodium intake was negatively correlated with all categories of the NK test (p<0.05). The adolescents reported that the principal barriers for adopting a healthy diet were the lack of willpower and a busy lifestyle. In this context, nutrition education is recommended and should also provide practicable healthy eating goals according to athletes´ lifestyle as well as target motivational barriers to increase adherence.

Context: The level of body awareness, performance emotional state (PES), and demographic characteristics in different sports are subjects to be investigated. It is important to examine the concepts of PES and body awareness to better understand the body–mind relationship in different sports. Objective: The aim of this study was to investigate the level of body awareness and PES of athletes. Design: In this cross-sectional study, the independent variables are groups (4 different sports), and the dependent variables are body awareness and PES. Participants: The study was conducted on 188 licensed athletes (85 footballers, 36 basketball players, 34 handball players, and 33 swimmers). The mean age of the participants was 14.64 (1.89) years, mean height was 172.44 (11.03) cm, and mean body weight was 62.35 (13.12) kg. Settings: Four sports clubs and 2 high schools were the intervention facilities. Intervention: Body Awareness Questionnaire and Continuous Optimal Performance Emotional Status Scale-2 were used for data collection. Sociodemographic information was recorded. Main Outcome Measures: One-way analysis of variance was used for analysis of normal distribution data in 4 different groups, and the Kruskal–Wallis test was used for the analysis of data that did not show normal distribution. Results: There was no difference in body awareness among the branches (P = .17). The PES of the footballers was better than that of other athletes (P = .01). The correlation between body awareness and PES was medium (r = .47, P < .01), and the correlations between body awareness and age, licensed year, and number of weekly training sessions were weak (r = .22, P < .01; r = .19, P < .01; r = .15, P = .03). Conclusions: The body awareness of athletes may not differ among different sports, but PES is related to many factors such as mood, age, license years, and number of training sessions. In rehabilitation and training, body awareness and PES should be evaluated together.

Background: Due to the pandemic, COVID-19 cases and deaths are increasing unexpectedly and precipitately. More importantly, asymptomatic carriers could infect healthy people through sneezing, coughing, and talking. Therefore, mask usage is required to prevent and control COVID-19. Objectives: This study was aimed at examining the knowledge, attitude, and performance levels (KAP) of the Iranian population regarding mask usage to prevent and control the COVID-19 outbreak during a one-month period from early April to early May 2020. Methods: A researcher-made, validated, and reliable questionnaire consisting of 30 questions on knowledge, attitude, and performance regarding mask usage was utilized. Data collection was performed through the online method. To do so, the online questionnaire link was provided for the participants via social networks. The correct and wrong answers were scored 1 and 0 points, respectively. The final score of each dimension was calculated and classified as 0 - 50% (low), 51 - 75% (moderate), and 75% > (good). Results: A total of 1581 participants took part in the study. Although the participants had good attitude (74%) and performance (70.80%), but only 13.70% of them had good knowledge regarding mask usage. Also, significant differences were found between the participants’ knowledge and higher educational levels (P < 0.001). There were significant associations between the participants’ age, gender, educational level, and job and their knowledge and attitude levels (P < 0.05). Besides, female participants had higher performance scores than did male participants (P < 0.001). The participants with governmental jobs had significantly higher performance than unemployed ones (P < 0.001). Conclusions: The participants obtained low KAP scores; therefore, it is required to train and inform the society and enhance their KAP levels via social media regarding the importance of mask usage, including proper donning, doffing, cleaning, disinfection, and safely and hygienic disposal procedures of masks to prevent and control COVID-19.

The objective was to characterize and compare the subgingival microbiota in patients diagnosed according to the World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions 2018. For this cross-sectional study, Spanish and Colombian subjects (characterized as health/gingivitis, periodontitis in stages I-II or stages III-IV) were clinically assessed, and subgingival samples were taken and processed by culture. The comparisons among patients with periodontal status (and between countries) was made using Mann–Whitney, Kruskal–Wallis, ANOVA and chi-square tests. The final sample consisted of 167 subjects. Eikenella corrodens and Parvimonas micra were more frequently detected in health/gingivitis and Porphyromonas gingivalis in periodontitis (p < 0.05). Higher total counts were observed in Colombia (p = 0.036). In Spain, significantly higher levels of P. gingivalis and Campylobacter rectus were observed, and of Tannerella forsythia, P. micra, Prevotella intermedia, Fusobacterium nucleatum, Actinomyces odontolyticus and Capnocytophaga spp. in Colombia (p < 0.001). P. micra was more prevalent in health/gingivitis and stage I-II periodontitis in Colombia, and P. gingivalis in all periodontitis groups in Spain (p < 0.05). As conclusions, significant differences were detected in the microbiota between health/gingivitis and periodontitis, with minor differences between stages of periodontitis. Differences were also relevant between countries, with Colombia showing larger counts and variability of bacterial species.
