  Creativity in sport is increasingly recognized as a developmental resource to be nurtured in all participants. Yet existing literature on how coaches nurture creativity has largely centred on task-based drills and prescriptive instruction. This chapter shows how transformational leadership serves as a supplement to these task-based approaches to foster creativity. Drawing on Amabile’s Componential Theory of Creativity, creativity arises from the interaction of four key elements: sport-specific skills, flexible thinking, task motivation, and a supportive social environment. These elements are linked to the four I’s of transformational leadership (idealized influence, inspirational motivation, intellectual stimulation, individualized consideration) to show how everyday leadership behaviours create conditions that help athletes think and act in new ways. Building on research in transformational leadership and creativity, the chapter presents ten creativity-nurturing principles for coaches that translate theory into daily coaching practice. Each principle includes a brief description and a concrete example. Together, the ten principles form a practical approach that coaches can use in daily training to embrace risk-taking, idea-sharing, and fresh solutions. The chapter closes with applied notes on adapting the principles for different athletes and sport settings and outlines directions for future research, including exploring barriers and enablers to implementation.

  There is agreement among athletes, coaches, and sport researchers that leadership is one of the most significant factors when performing and operating in elite sport. There is, however, a lack of understanding of how the behaviors of coaches as leaders could be considered as destructive. The aim of this study was to explore elite sport athletes’ perceptions and experiences of destructive coach leadership behavior. Informants in this study were a convenience sample of eight (four female and four males) current or former World Class/international elite athletes in handball and soccer, with an average of 12 years of experience at elite level. Using semi-structured interviews and conducting a reflective thematic analysis we identified three main categories of perceived destructive leadership behavior from the coaches described as: Active Destructive Behaviors; Passive Destructive Behaviors, and Incompetent Coach Behaviors. Recognizing these behaviors is the first step in attempting to eradicate them.

  Relative age effects (i.e., a systematic bias favouring individuals born earlier in the selection year) have been found in many traditional sports, especially among younger athletes in sports where physical maturation (e.g., increased size and strength) is advantageous. The aim of this study was to explore relative age effects in professional esports, which differ from traditional sports in some key areas. The birth months of 15,734 e-sport athletes playing ten different games were collected from Liquipedia and analyzed using chi-square tests. The analyses showed no practically meaningful relative age effects among the athletes, indicating that being relatively older does not yield advantages in gameplay. The same results applied across the various age groups as well as the different game types. This lack of relative age effects can likely be attributed to the cognitive and skill-based nature of esports, as well as the flexible and online nature of competitive environments in this domain

  The phenomenon of father-son dyads in professional sports is commonly acknowledged through anecdotes, but there is limited understanding regarding the dynamics within multi-generational sporting families. This study aimed to investigate father-son dyads within professional football, seeking insights into the influence of former professional athlete parents on their children’s sporting development. Interviews were conducted with the fathers and sons from three dyads, all of whom represented the Norwegian national football team. The data were analyzed using reflexive thematic analysis. The results that were generated through the analytic process highlighted several key aspects: (1) Former professional athlete-fathers perceived as role models that shaped their sons’ interests, behaviors, and aspirations for success, (2) Active involvement where the fathers played football with their sons and ensured quality practice, (3) Fathers as providers of opportunities, drawing from their own experiences, recognition, and professional networks, and (4) Fathers providing tangible and emotional support while balancing demands and expectations. Across all themes, fathers maintained a relaxed perspective on elite sport, emphasizing that football’s primary value lies in enjoyment and positive youth development rather than becoming an elite athlete. Notably, the results highlighted that the fathers’ behaviors, actions, and approaches aligned with existing literature and recommendations pertaining to parental involvement in sport. However, it was also apparent in the findings that the sons benefited from some unique aspects arising from having a parent with elite athlete status. This included fathers serving as an inspiring figure due to their professional career, granting access to exclusive experiences, and possessing insights into the demands of professional sports thereby offering invaluable advice and guidance. In essence, this study not only reaffirms established guidelines for parental involvement in sports but also illuminates the potential added value derived from having a parent with a background in elite athletics.

  Even though parents are expected to support their child in an academy football context, little is known about the impact of parental involvement in this period. The aim of the present study was to study perceptions of athletes’ and their parents in their athletic transitions in a Norwegian professional football academy. Five parents and five players who had played in a Norwegian professional football academy between the ages of 16 and 18 years were interviewed in retrospect. Both parts described few athletic challenges, level of performance and playing in new positions were considered difficult to handle. Since only one of the players ended up playing professional football, we discuss in which degree the lack of pressure from most parents might have impacted on this fact. The results show however that the support the parents offer is considered important also when these players entered the professional club as junior players.

  One perspective on leadership that has recently gained increased attention in sport is identity leadership; however, research on elite sport teams is still in its infancy. Thus, the main purpose of this research is to investigate identity leadership in elite team sports in relation to task cohesion, and subsequently to explore the mediating role of the intra-team communication dimensions of acceptance and distinctiveness. A cross-sectional design was employed and 441 elite athletes from division 1 and division 2 in handball and ice hockey participated in the present study. Structural equation modeling was used to assess relationships between identity leadership and task cohesion, and the mediating role of acceptance and distinctiveness. Results revealed that identity leadership positively predicted task cohesion, and that this relationship was mediated by intrateam communication acceptance. In conclusion, findings in the present study expand our understanding of performance-related benefits of identity leadership in elite sport.

  This study investigated the association between referee efficacy and self-reported coping with external stressors among elite handball and football referees. The participants were 224 Norwegian elite referees of handball (n = 111, m age = 35.3 years, 13.5% females) and football (113, m age = 30.8 years, 8% females) who had been referees for an average of 14.4 years (sd = 7.77 years; min: 4, max: 37) and a referee at the present level for 6.8 years (sd = 6.20 years, min: 1, max: 32). Referee self-efficacy was measured using the Norwegian version of the Referee Self-Efficacy Scale. Self-reported coping with external stressors was measured using responses to statements related to the referee’s self-perceived decision-making process in the presence of several sources of external stressors. Referee self-efficacy was positively associated with coping with external stressors (b = .24 (se = .11), p = .021). Football referees reported higher levels of coping with external stressors (b = .28 (se = .08), p = .001) than handball referees, and the number of years of elite refereeing was positively related to coping with external stressors. The findings provide evidence of a positive relationship between referee efficacy and coping with external stressors when making decisions. Keywords: Referee Self-Efficacy Scale, decision-making, social pressure, team sport referees

  The purpose of this study was to gain insight into how young football players experience combining sports-related upper secondary education with being a player at a high national level. More specifically, this study will look at players’ experience of the opportunity to complete a “dual career” (Stambulova & Wylleman, 2015) in the form of time and facilitation of investment in both football and school, and regulation of organized training in the form of deliberate practice (Ericsson et al., 1993) to optimize players’ opportunities for development as football players. The participants consist of eight informants who have all attended a sports study program in upper secondary school and were included in the senior squad of a club in Norwegian top football. The informants were interviewed about their experience of how it affected their development as football players. The results showed that the players’ motives for choosing a sports discipline were mainly based on sporting motives and to a lesser extent school-related, where in many ways they consider the sports program study program only as a tool to prioritize football and increase their commitment to a football career. The players also described a large degree of facilitation for sporting development with a holistic approach, although they sometimes describe large amounts of training, which they perceived as positive for their development, but also as a tough physical strain. The results showed a clear difference in favor of the best players who had a better organized everyday life compared to players with a lower skill level. Even though the school tried to facilitate the school subjects, this arrangement worked, according to the players, somewhat worse than the sporting one. An important function in this context was that the players had a contact person between the club and the school, who arranged between the two parties, to some frustration among the teachers according to the players, who perceived that the facilitation went too far. It may seem that the sports-related fields of study fulfill their purpose of facilitation, but mainly on the basis of the sporting and to a lesser extent in relation to the school subjects, with the exception of the study-specific subjects.

  There is a growing body of the literature highlighting the positive impact of transformational leadership behaviours across contexts, including sport. However, there is a lack of knowledge of this relationship within elite sport settings. Thus, the purpose of the present study was to examine the relationship between elite youth athletes’ perceptions of coaches’ transformational coaching-behaviours and variables that have been linked to transformational leadership in other settings (i.e., group cohesion, motivational climate, self-regulation of learning and athlete satisfaction). Norwegian elite youth soccer players (n = 753) selected into the national talent development program completed questionnaires to measure the variables of interest. Using structural equation modelling, results revealed a positive path from transformational leadership to both task and social cohesion, taskoriented motivational climates, self-regulation of learning and athlete satisfaction. Finally, a negative path from transformational leadership to ego-oriented climates was identified. The findings are in line with previous research in associating transformational leadership behaviours with adaptive outcomes, and further indicating that such relationships may also be valid in elite sport contexts.

  The personal assets framework suggests that dynamic elements of (a) personal engagement in activities, (b) quality social dynamics, and (c) appropriate settings will influence an athlete’s long-term outcomes of performance, personal development, and continued participation in sport. The aim of the present study was to conduct a case study of a Norwegian age-restricted team that was successful in promoting participation, performance, and positive development for individual participants and to investigate how the dynamic elements of activities, social dynamics, and settings have led to these long-term outcomes. The results indicated that the case is a best-practice example of successful attainment of personal development and long-term participation and performance through appropriate structure and application of the dynamic elements within the personal assets framework, including enjoyable peer-led play activities and quality practice, quality relationships with teammates and coaches, and access to facilities.

  Past studies have indicated that multiple factors may influence sport referees' decisions, such as pressure from spectators and athletes' reputation. Grounded in the social impact theory framework, this study examined whether Norwegian Premier League (NPL) referees are biased by a team's success when awarding penalties. Using video footage (similar to video assistant referees), an expert panel (EP) of four NPL referees evaluated all potential penalty situations (N = 43) involving either of two successful teams during an entire NPL season. Fifty-five potential penalty situations from matches without successful teams were also rated. Overall, the match referees identified 73.3% (22 of 30) of the EP-identified penalties during matches without successful teams. Successful teams were awarded 110% (11 of 10) of the EP-identified penalties, while their opponents were awarded 12.5% (1 of 8). Chi square statistic revealed that successful teams were more likely to receive an incorrect penalty compared with their opponents, and less likely to be denied a penalty they should have been awarded. These findings indicate that referees' decisions may be unintentionally biased by a team's success, extending our knowledge about how football referees may be influenced by social forces.

  Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study’s purpose is to examine the relationship between the perceived motivational climate, supportive coach-behaviour, and athletes’ personal treatment satisfaction among young soccer players. More specifically, we investigated the moderating effect of supportive coach-behaviour on the relationship between motivational climate and personal treatment satisfaction. Five hundred and thirty-two players (Mean age = 15.4 years, SD = 1.2) attending a Norwegian national soccer tournament participated in the study. Self-completion questionnaires were used to attain data. A linear regression analysis revealed that mastery of climate and supportive coach-behaviour were positively associated with personal treatment satisfaction. A negative association was found between performance climate and personal treatment satisfaction. Further, moderation analyses revealed that supportive coach-behaviour moderated the relationship between performance climate and personal treatment satisfaction. The findings indicate that a performance climate may not be as maladaptive when coaches provide supportive behaviour. The findings highlight the value of a further examination of the interaction between motivational climate and coaching behaviours, and its potential relations to young athlete’s sport experience.

  One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine the coaches and players’ perceptions of soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed that players born early in the selection year considered themselves stronger and faster than late born players. Similar, coaches considered the players born early in the selection year stronger than players born late in the selection year. Neither the players or coaches considered the early born players as technically, tactically and mentally better. Within a talent development program, we argue that coaches and recruiters should be aware of differences in relative age, and thus prevent that late born players must compensate their physical disadvantages to be allowed into such programs.
