Toward a knowledge-synthesis heuristic for sport leaders: the strategic leader synthesis model.

Sport management leadership research has predominantly focused on leadership behaviours, particularly transformative leadership, without fully acknowledging the complex, multifaceted nature of leadership within the sports context. This perspective overlooks the reality that sports leaders operate within complex organizations and varied contexts that significantly influence their behaviours. Leadership in sports demands core capabilities in decision-making, communication, and strategic thinking, and a mindset that influences perception, decision-making, and behaviour. Consequently, a singular focus on transformative leadership may undervalue the importance of other attributes. This paper thus argues for a comprehensive leadership framework that integrates behaviours, roles, capabilities, and mindset, and draws insights from business management. By proposing this framework organized across four domains-Context, Roles, Capabilities, and Mindset-this paper aims to foster a deeper understanding of sports leadership dynamics, highlighting the necessity of a holistic approach that considers the interconnectedness of these elements.

An Evaluation of the Sharing Dance Public School Program on Physical Literacy.

Introduction: Physical literacy (PL) is a multidimensional concept that includes the domains of movement competence, positive affect, social participation, and the confidence, motivation, and knowledge and understanding necessary for regular engagement in physical activity. The Sharing Dance Public School Program was created by Canada's National Ballet School specifically designed to promote PL through dance. The objective of this study was to evaluate the effectiveness of the program to improve PL in grade 4 to 6 children over the course of a school year. Methods: Children were initially recruited from two schools including an intervention and a control school. However, due to the COVID-19 pandemic, data collection was prematurely terminated which resulted in baseline and mid-point data from the intervention group only. As such, participants included 57 children (n = 28 females, Mage = 10.34 ± 0.85 years) that engaged in the dance program once per week for 50 minutes. Assessments of PL included a direct measure of movement competence (PLAYfun) and a self-report measure (survey) to assess the other domains of PL. Results: Significant improvements were found in movement competence. However, significant decreases were found for fun and enjoyment, confidence, and social participation. No changes were observed for knowledge and understanding or overall PL. Conclusions: Findings from the present study are encouraging as they provide initial evidence for the support of community-based PL programs, such as the Sharing Dance Public School Program, to help children develop their movement competence. Future research is needed to further evaluate the effectiveness of the Sharing Dance Public School Program over a school year, and when compared to a control group, as was initially intended.

Auditory rhythm facilitates perception and action in children at risk for developmental coordination disorder.

Developmental Coordination Disorder (DCD) is a common neurodevelopmental disorder featuring deficits in motor coordination and motor timing among children. Deficits in rhythmic tracking, including perceptually tracking and synchronizing action with auditory rhythms, have been studied in a wide range of motor disorders, providing a foundation for developing rehabilitation programs incorporating auditory rhythms. We tested whether DCD also features these auditory-motor deficits among 7-10 year-old children. In a speech recognition task with no overt motor component, modulating the speech rhythm interfered more with the performance of children at risk for DCD than typically developing (TD) children. A set of auditory-motor tapping tasks further showed that, although children at risk for DCD performed worse than TD children in general, the presence of an auditory rhythmic cue (isochronous metronome or music) facilitated the temporal consistency of tapping. Finally, accuracy in the recognition of rhythmically modulated speech and tapping consistency correlated with performance on the standardized motor assessment. Together, the results show auditory rhythmic regularity benefits auditory perception and auditory-motor coordination in children at risk for DCD. This provides a foundation for future clinical studies to develop evidence-based interventions involving auditory-motor rhythmic coordination for children with DCD.

Physical Activity and Motor Skill Development During Early Childhood: Investigating the Role of Parent Support.

PURPOSE: This study examined the relationship between parent physical activity (PA) support and children's motor skill development and PA during early childhood and explored the potential moderating effect of child PA and motor skills on these relationships. METHODS: Participants (N = 589, 250 girls, meanage = 4.93 [0.59] y) were part of a larger, longitudinal cohort study. Motor skills were assessed using the Movement Assessment Battery for Children-Second Edition. Moderate to vigorous PA (MVPA) was measured using ActiGraph accelerometers. Five items were used to measure parent support frequency (1 = none, 3 = 3-4 times, 5 = daily). Moderation analyses were conducted to examine the moderating effect of MVPA and motor skills on the relationship between parent support and motor skills and MVPA, respectively. RESULTS: Parent support was significantly related to motor skills (B = 14.45, P = .007), and child MVPA significantly moderated this relationship (B = -0.17, P = .021). The relationship between parent support and child MVPA did not reach significance (B = 2.89, P = .051); however, motor skills had a significant moderating effect (B = -0.08, P = .022). CONCLUSIONS: These novel findings suggest parent PA support is related to child motor skills and PA during early childhood, but this relationship is context dependent. Child-level characteristics should be considered in future parent PA support research.

The Sport Experience Measure for Children and Youth (SEM:CY): A Rasch Validation Study.

This study employed Rasch analyses to validate a novel measure of sport experience: the Sport Experience Measure: Children and Youth (SEM:CY). Analyses were applied to self-reported data of n = 503 young people (age 9-18 years, M = 12.91, 50% female) in Canada who were engaging in sport during the previous 12 months. The revised measure, consisting of 24 items on a 3-point response scale, demonstrated good fit statistics (e.g., item fit residual: M = -0.50, SD = 0.94 and person fit residual: M = -0.62, SD = 2.33), an ability to reliably discriminate between levels of sport experience, and an absence of differential item functioning for various groups (males and females, older and younger individuals, solo and team sports, and those playing at various competitive levels, including recreation). The SEM:CY is a succinct tool that can serve as a valuable means to gauge the quality of an individual's sport experience, which can facilitate positive youth development and sustain participation across the life span.

Investigating the impact of developmental coordination difficulties across home, school, and community settings: Findings from the Australian Impact for DCD survey.

AIM: To evaluate the participation difficulties experienced by children with developmental coordination disorder (DCD) in home, school, and community environments. METHODS: The Impact for DCD survey was completed by primary caregivers of 4-18-year-old children with DCD (or synonymous diagnosis) (n = 429). OUTCOMES AND RESULTS: The greatest participation difficulties experienced at home included dressing, eating with utensils, self-care tasks and drawing/writing reported by over 70% of families. At school, fine motor difficulties were also frequently reported, with additional difficulties keeping up or completing tasks, and not feeling supported at school. Socialisation challenges and bullying were also commonly reported (34.9%). As a result of participation difficulties at school, 5.4% were home schooled. Many children engaged in community activity, with 72.0% currently engaged in at least one organised sports-based activity. CONCLUSIONS AND IMPLICATIONS: Increased recognition of the widespread impact of DCD in a child's life is crucial at an individual and societal level. Parents reported their children experiencing significant participation restrictions and difficulties. The findings of this large-scale study have revealed that most children with DCD are not receiving the support they need to thrive, especially at school. This largely reflects a lack of understanding and recognition of the condition and its associated challenges.

Independent and Joint Associations of Physical Activity and Sleep on Mental Health Among a Global Sample of 200,743 Adults.

BACKGROUND: Previous research has demonstrated that both sleep and physical activity (PA) are independently associated with various indicators of mental health among adults. However, their joint contribution to mental health has received limited attention. The present study used cross-sectional data from the Mental Health Million Project to examine the independent and joint effects of sleep and PA on mental health among a global sample of adults, and whether these effects differ among individuals receiving mental health treatment. METHOD: The sample included 200,743 participants (33.1% young adults, 45.6% middle-aged adults, 21.3% older adults; 57.6% females, 0.9% other) from 213 countries, territories, and archipelagos worldwide that completed a comprehensive 47-item assessment of mental health including both problems (i.e., ill-being) and assets (i.e., well-being): the Mental Health Quotient. Participants also reported their weekly frequency of PA and adequate sleep, and mental health treatment status. A series of generalized linear mixed models were computed. RESULTS: Independent dose-response associations were observed, whereby greater amounts of PA and adequate sleep were each associated with better mental health. In addition, a synergistic interaction was observed in which the positive correlation of PA with mental health was strengthened with greater frequency of adequate sleep. These benefits were less pronounced among adults receiving mental health treatment. CONCLUSION: While findings suggest sleep can help to offset the negative influence of a physically inactive lifestyle (and vice versa), our results point to a "more is better" approach for both behaviors when it comes to promoting mental health.

Parent Support for Physical Activity and Motor Skills During Early Childhood: A Mixed-Methods Application of the Multi-process Action Control Framework.

BACKGROUND: Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address the high rates of inactivity in children. Parent support is a determinant of PA in children, however, parental intentions to support are not always translated into behavior resulting in an intention-behavior gap. PURPOSE: Positioned within the multi-process action control (M-PAC) framework, this study used an explanatory concurrent mixed-methods design to explore parents' intentions and support of PA and FMS during early childhood. METHODS: Parents (N=124) of children aged 3-4 years completed an online survey consisting of items assessing reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes of M-PAC and intentions and support for child PA and FMS. A subset of parents (n=20) completed a semi-structured online interview guided by the M-PAC framework. RESULTS: Significantly more parents intended to support PA (71%) compared with FMS (44%; p<0.001) and successfully translated intentions into action for PA (57%) compared with FMS (27%; p<0.001). Discriminant function analysis showed parent behavior profiles for PA and FMS support were associated with a combination of reflective, regulatory, and reflexive processes, however, these differed based on support behavior. Qualitative findings highlighted parents' differential views on PA and FMS support and contextualized the psychological processes associated with each. CONCLUSIONS: Parent PA support interventions during early childhood should include strategies for supporting FMS. Interventions should prioritize fostering a combination of reflective, regulatory, and reflexive behaviors to translate intentions to support PA and FMS into behavior among parents of young children.

Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address physical inactivity in young children. Parent support is a known predictor of PA in children, however, parents who intend to support PA do not always follow through with these intentions. This is referred to as the intention­behavior gap. Applying the theoretical tenets of the multi-process action control framework, this study surveyed 124 parents of children aged 3­4 years on reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes, intentions, and behaviors related to parent PA and FMS support. Follow-up interviews were completed with 20 parents to gain a deeper understanding of parent PA and FMS support behaviors. Survey findings showed that parents' intentions and support behaviors for their child's PA and FMS were associated with a combination of reflective, regulatory, and reflexive processes. Interview findings highlighted more favorable parent perspectives toward PA support compared with FMS and further explained the psychological processes associated with each. Future parent PA support interventions during early childhood should include FMS support strategies and foster a combination of reflective, regulatory, and reflexive behaviors to bridge the gap between intentions and support behaviors among parents of young children.

Cumulative Prenatal Risk Factors and Developmental Coordination Disorder in Young Children.

OBJECTIVES: To examine the effect of cumulative prenatal risk factors (RFs) on the presence of Developmental Coordination Disorder (DCD) in young children. METHODS: Participants (N = 589, 338 boys, Mage = 4.5 ± 0.5 years) were from a larger cohort study, the Coordination and Activity Tracking in Children (CATCH). Motor coordination was assessed using the Movement Assessment Battery for Children- 2nd Edition. Children were classified as at risk for DCD (DCDr) based on European Academy of Childhood Disability guidelines. RFs were obtained through a parent-completed survey. A multiple logistic regression was conducted to examine the effect of the RFs on DCD. RESULTS: Results showed that the odds of a child having DCDr are significantly higher with a greater total number of prenatal RFs, after adjustment for mother's age at child's birth, child's sex, child's age, marital status and total annual household income (OR = 1.48, p < 0.01). CONCLUSIONS: These findings warrant further investigation into the cumulative impact of multiple prenatal RFs and whether specific combinations of RFs might be more strongly linked to DCD than others. These results provide additional insight into possible causes and prevention of DCD.

Reliability of field- and laboratory-based assessments of health-related fitness in preschool-aged children.

OBJECTIVES: Reliable measurements of health-related fitness-cardiorespiratory endurance, muscular endurance, muscular strength, body composition, and flexibility-are imperative for understanding and tracking health-related fitness from the preschool age. This study aimed to examine the test-retest reliability of field-based (i.e., sit and reach [standard and back-saver], standing long jump, grip strength); and laboratory-based (i.e., Bruce Protocol Treadmill Test, Wingate Anaerobic Test) assessments of health-related fitness in preschool aged children (4-5 years). METHODS: Forty-two typically developing children participated in both assessment time points separated by 2-3 weeks. All fitness assessments were administered individually and repeated in the same order by the same assessor. Heteroscedasticity was examined for each parameter. Intraclass correlation coefficients were calculated to assess test-retest reliability. RESULTS: All parameters were homoscedastic. Test-retest reliability for the field-based tests and Bruce Protocol Treadmill Test parameters were moderate to good. Test-retest reliability for the Wingate Test parameters were good to excellent for maximum pedal rate, peak power, and peak power/kg; mean power and fatigue measured at 10 and 30 s demonstrated moderate to excellent test-retest reliability. CONCLUSION: The standard sit and reach, grip strength, and short-term muscle power from the Wingate test are reliable assessments of health-related fitness in preschool-aged children.

The golden ratio in baseball: the influence of historical eras on winning percentages in major league baseball.

Introduction: The golden section or golden ratio (61.8% or 0.618) is a mathematical phenomenon that appears in art, literature, music and nature with such ubiquity that it is thought to be a fundamental principle of aesthetic organisation. The golden ratio also manifests in sport, particularly as the proportion of wins to losses required to win a Major League Baseball championship. This study extends early work on the golden ratio in baseball by incorporating more than three decades of additional data. Methods: This study involved a historically contextualized examination of how winning percentages have changed across the seven historical eras of modern baseball, including analyses of the relative contribution of offensive and defensive statistics to championship winning teams. Data was extracted from Baseball Reference and included statistics for 398 championship winning teams from both the American and National Leagues between 1901 and 2019. Pearson correlation coefficients were computed for winning percentage with indicators of offensive and defensive performance during each era. Main and interaction effects of Era and League on winning percentage were examined using factorial ANOVA, with follow-up analyses examining whether the golden ratio was included in each factor's 95% confidence interval. Results: Our findings suggest that winning percentages for championship teams were closest to the golden ratio during eras where the relative contribution of offense and defense was most closely balanced: the Integration Era (1942-1960) and the Expansion Era (1961-1976). Discussion: Previous scholarship theorizes that the golden ratio represents an aesthetic ideal or a Gestalt archetype. If this aesthetic theory is applied to sporting competition, these results suggest that baseball may be most aesthetically appealing to fans when offense and defense is balanced in such a way as to ensure that championship teams win 61.8% of their games.

Bi-directional associations between physical activity and growth indicators of pre-school aged children.

Physical activity for young children provides a wealth of benefits for health and development. However, little is known about the inter-relationship of physical activity and growth indicators. The aim of this study was to test the bi-directional associations of physical activity and growth indicators in children under five years of age. This prospective study included 1,575 children with data on physical activity and growth indicators at ages 12, 24 and 48 months. Accelerometers were used to measure physical activity. Z-scores for length/height-for-age, weight-for-length/height, weight-for-age and body mass index (BMI)-for-age were calculated. Bi-directional associations between physical activity and growth indicators were evaluated using cross-lagged panels based on Generalized Estimating Equations and cross-lagged structural equation models. Physical activity was consistently associated with lower weight-related growth indicators: BMI-for-age: ß=-0.12; Weight-for-age: ß=-0.11; Weight-for-length/height: ß=-0.12. Higher BMI-for-age indicated lower physical activity (ß=-0.06). When the exposure was lagged, the association of physical activity on weight-related growth indicators remained, but weight-related growth indicators showed a negative association on physical activity. A bi-directional association between physical activity and weight-related growth indicators was observed. The magnitude of associations were stronger when physical activity was modelled as exposure. These results reinforce the importance of physical activity since early years.

Towards the development of a quality youth sport experience measure: Understanding participant and stakeholder perspectives.

Quality sport experiences may be a key underlying mechanism through which continued sport participation may facilitate positive youth development. However, what constitutes a quality sport experience for youth is poorly understood due to a lack of comprehensiveness among existing measures. This study aimed to identify the salient factors that constitute quality sport experience for youth by capturing athletes and stakeholder perspectives with a broader goal of developing a more robust quality sport experiences measure. A total of 53 youth athletes and stakeholders (i.e., parents, coaches, and sport administrators) completed semi-structured interviews or focus groups about what they felt were important aspects of a quality sport experience for youth. Inductive content analysis of the data identified four themes representing important indicators for a quality sport experience for youth: fun and enjoyment, opportunity for sport skill development and progress, social support and sense of belonging, and open and effective communication. These higher order themes were found among each of the groups that have important interpersonal relationships with athletes, as well as among athletes themselves. Each of these themes were also related to one another. Collectively, findings outline a framework to understand what constitutes a quality sport experience for youth. The Quality Sport Experience Framework for Youth will help in the development of a quantitative tool to assess this construct and enable researchers to examine how these experiences contribute to continued engagement in sport and positive developmental outcomes among youth sport participants.

A cross-sectional study of Canadian children's valuation of literacies across social contexts.

Background: Children, on average, do not engage in sufficient physical activity to reap the physical, mental, and social health benefits. Understanding the value that children place on movement across social contexts, and the relative ranking of this valuation, may help us to understand and intervene on activity levels. Method: This exploratory study examined the valuation of reading/writing, math, and movement across three social contexts (school, home, with friends) among children 6-13 years of age (N = 7,845; 51.3% male). Subjective task values across contexts were assessed with the valuing literacies subscale of the PLAYself. One-way Kruskal-Wallis ANOVAs were performed to test for differences between contexts and between literacies, respectively. Results: Sex differences and age-related variation were explored. Valuations of reading/writing (d = 1.16) and math (d = 1.33) decreased across context (school > family > friend), while the valuation of movement was relatively stable (d = 0.26). Valuations differed substantially with friends (p < 0.001, d = 1.03). Sex dependent effect sizes were minimal (d = 0.05-0.11). Conclusions: Movement is highly valued by children across social contexts; thus, programming across contexts should be prioritized to align with their valuation.

Physical Activity Trajectories in Early Childhood: Investigating Personal, Environmental, and Participation Factors.

INTRODUCTION/PURPOSE: To determine personal, environmental, and participation factors that predict children's physical activity (PA) trajectories from preschool through to school years. METHODS: Two hundred seventy-nine children (4.5 ± 0.9 yr, 52% boys) were included in this study. Physical activity was collected via accelerometry at six different timepoints over 6.3 ± 0.6 yr. Time-stable variables were collected at baseline and included child's sex and ethnicity. Time-dependent variables were collected at six timepoints (age, years) and included household income (CAD), parental total PA, parental influence on PA, and parent-reported child's quality of life, child's sleep, and child's amount of weekend outdoor PA. Group-based trajectory modeling was applied to identify trajectories of moderate-to-vigorous PA (MVPA) and total PA (TPA). Multivariable regression analysis identified personal, environmental, and participation factors associated with trajectory membership. RESULTS: Three trajectories were identified for each of MVPA and TPA. Group 3 in MVPA and TPA expressed the most PA over time, with increased activity from timepoints 1 to 3, and then declining from timepoints 4 to 6. For the group 3 MVPA trajectory, male sex (ß estimate, 3.437; P = 0.001) and quality of life (ß estimate, 0.513; P < 0.001) were the only significant correlates for group membership. For the group 3 TPA trajectory, male sex (ß estimate, 1.970; P = 0.035), greater household income (ß estimate, 94.615; P < 0.001), and greater parental total PA (ß estimate, 0.574; P = 0.023) increased the probability of belonging to this trajectory group. CONCLUSIONS: These findings suggest a need for interventions and public health campaigns to increase opportunities for PA engagement in girls starting in the early years. Policies and programs to address financial inequities, positive parental modeling, and improving quality of life are also warranted.

Holding open spaces to explore beyond: Toward a different conceptualization of specialization in high-performance sport.

This conceptual analysis aims to challenge the state of high-performance sport by questioning the concept of specialization. To start, we offer a brief, but critical overview of what specialization currently entails. Then, shifting the paradigm, we suggest an expansion rather than a reduction of developmental possibilities once an athlete reaches the "top". Specifically, rather than athletes conforming to national standards imposed by governing bodies about what it means to be "elite", we suggest sport systems consider a person-environment fit approach to support ongoing development. Drawing on an ecological dynamics rationale and various socio-cultural theories, we explore how concepts such as affordances and perspectives can be harnessed to create a better "fit" between athletes' action capabilities and the opportunities within their broader environment. Our conception of specialization requires moving away from a definition of success based on the accumulation of medals, toward one that accounts for the exploration and achievement of the possible. We argue that a person-environment fit welcomes diversity, so long as it sustains the person's health, wellbeing, and performance. This, it is suggested, is about collectively holding open spaces for each other to explore beyond the constraints of high-performance sport, encouraging all to carry on their lives in directions meaningfully impactful for them. We conclude this conceptual analysis with a brief case example demonstrating what our theorizing could look like in practice.

Development, explanation, and presentation of the Physical Literacy Interventions Reporting Template (PLIRT).

BACKGROUND: The physical literacy (PL) concept integrates different personal (e.g., physical, cognitive, psychological/affective, social) determinants of physical activity and has received growing attention recently. Although practical efforts increasingly adopt PL as a guiding concept, latest evidence has shown that PL interventions often lack specification of important theoretical foundations and basic delivery information. Therefore, the goal of the present study was to develop an expert-based template that supports researchers and practitioners in planning and reporting PL interventions. METHODS: The development process was informed by Moher et al.'s guidance for the development of research reporting guidelines. We composed a group of ten distinguished experts on PL. In two face-to-face meetings, the group first discussed a literature-driven draft of reporting items. In the second stage, the experts anonymously voted and commented on the items in two rounds (each leading to revisions) until consensus was reached. RESULTS: The panel recommended that stakeholders of PL initiatives should tightly interlock interventional aspects with PL theory while ensuring consistency throughout all stages of intervention development. The Physical Literacy Interventions Reporting Template (PLIRT) encompasses a total of 14 items (two additional items for mixed-methods studies) in six different sections: title (one item), background and definition (three items), assessment (one item each for quantitative and qualitative studies), design and content (five items), evaluation (one item plus one item each for quantitative and qualitative studies), discussion and conclusion (two items). CONCLUSION: The PLIRT was designed to facilitate improved transparency and interpretability in reports on PL interventions. The template has the potential to close gaps between theory and practice, thereby contributing to more holistic interventions for the fields of physical education, sport, and health.

Reliability of Fitness Assessments in Children With Emotional and Behavioral Difficulties.

PURPOSE: Examine the reliability of field-based fitness assessments in school-aged children with emotional or behavioral difficulties (EBD). Understanding the impact of fitness on physical activity participation for children with EBD is limited by our ability to reliably measure it. METHODS: Fifteen children aged 7-12 years with EBD completed 7 assessments-standing broad jump, overhead throw, grip strength, isometric plank hold, isometric wall squat, unilateral heel raise, and modified 6-minute walk test-in a random order on 2 separate occasions. Intraclass correlation coefficients (ICCs) were computed to evaluate reliability. RESULTS: ICCs ranged from .65 to .99 representing moderate to excellent reliability for all assessments. Shorter assessments requiring less attention and behavior regulation tended to demonstrate higher ICC values while assessments with greater attention or behavioral regulation demands tended to have lower ICC values. CONCLUSION: Results demonstrate varied reliability for fitness tests in children with EBD. Practitioners can use grip strength and standing broad jump assessments with confidence. Other assessments have good reliability but greater variability indicating they may be a challenge for some children with EBD.

Group differences and associations among stress, emotional well-being, and physical activity in international and domestic university students.

Objective: To examine the differences in experiences of stress, emotional well-being, and physical activity among international and domestic students. Participants: Domestic (n = 4,035) and international (n = 605) students at a large Canadian university. Methods: Responses to items on stress, emotional well-being (happiness and satisfaction with life), and moderate-to-vigorous physical activity (MVPA) and strength training were self-reported. Group differences were explored in a multivariate analysis of variance model, and student status was tested as a moderator of the associations between stress, emotional well-being (happiness and satisfaction with life), and MVPA. Results: International students reported significantly lower stress and emotional well-being compared to domestic students, and fewer days of MVPA. Student status moderated the association between stress and MVPA, with the association significant for domestic students. Conclusions: Given the findings, international students may have distinct attitudes and beliefs toward MVPA that could be targeted in tailored interventions.
