ABSTRACT
Introduction: This meta-analysis investigates the relationship between coach leadership behaviors and athlete satisfaction and group cohesion within the realm of Chinese sports. The study also explores player sex and player classification as potential moderating variables. The primary focus is on evaluating the impact of coaching behaviors, as measured by the Leadership Scale for Sports, on athlete satisfaction and group cohesion. Methods: Standard literature searches from China National Knowledge Infrastructure and Wanfang academic databases produced 26 studies encompassing a total of 319 effect sizes and a participant pool of 7,121 athletes across various sports. Results: Using the Comprehensive Meta-Analysis (CMA) to examine relevant data, results reveal a moderate and positive association between coach leadership and athlete satisfaction (ES = 0.412). Specifically, training and instruction (ES = 0.531), positive feedback (ES = 0.526), social support, and democratic decision-making exhibit positive effects, while autocratic behavior demonstrates a marginal positive effect. Similarly, a moderate positive relationship is identified between coach leadership and overall group cohesion (ES = 0.275), with training and instruction (ES = 0.396), social support (ES = 0.356), positive feedback, and democratic behavior positively influencing cohesion. Conversely, autocratic behavior has a small negative impact on cohesion. Furthermore, female athletes (ES = 0.603) and professional players (ES = 0.544) display stronger positive associations between coach leadership and satisfaction. Conclusion: These findings highlight the significance of diverse coaching behaviors aligned with player characteristics for fostering positive athlete satisfaction and group cohesion within the Chinese sports context, offering valuable guidance to Chinese coaches aiming to enhance their coaching strategies.
ABSTRACT
This study examined the relationship between the transformational leadership of PE instructors and students' satisfaction in an online PE class. In particular, it aimed to investigate whether the PE instructors' transformational leadership behaviors could predict students' satisfaction toward the class, their PE teacher, and their health and fitness. Furthermore, this study explored these relationships in male and female students. A total of 448 university students (male = 228; female = 220) between the ages of 18 and 22 participated in the study. The results revealed a positive relationship between the transformational leadership behaviors of PE instructors and students' satisfaction with online PE classes. Moreover, male and female students' satisfaction with the teaching of their PE instructor, feelings of fun and enjoyment, and perception of improved health and fitness in their online PE classes varied greatly as they perceived specific behaviors of transformational leadership from their PE instructors. These findings demonstrate that PE instructors play an important role as (online) classroom leaders in enhancing students' satisfaction with online learning. Therefore, PE instructors should be mindful to demonstrate transformational leadership to improve their effectiveness when conducting online classes.
ABSTRACT
Introduction: Investigation on the association between attention deficit hyperactivity disorder (ADHD) and primary reflexes is in the initial stage, with considerable differences in the findings. This study evaluated the association between ADHD and primitive reflexes using systematic review and meta-analysis. Methods: Data were obtained from PubMed, Cochrane Library, Web of Science, EBSCO (Medical Literature Analysis and Retrieval System Online, American Psychological Association Psyclnfo, and Education Resources Information Center), Embase, Scopus, and ProQuest. Articles were searched from the date of inception of the respective databases to January 01, 2023, and StataCorp Stata (version 15) was used for the analysis. Results: Four articles with 229 samples were included in the meta-analysis. Results showed a significant positive and moderate correlation between ADHD and primitive reflexes, particularly asymmetric tonic neck reflex: summary r value = 0.48, 95% CI = 0.27-0.64; symmetric tonic neck reflex: summary r value = 0.39, 95% CI = 0.25-0.52. Overall, findings from the sub-group analysis indicate that the behavioral problem measuring tool (Conners' scale), sex, and primitive reflex test could significantly moderate the relationships between ADHD and ATNR and STNR primitive reflexes. Conclusion: ADHD symptoms in children are closely related to the non-integration of (a)symmetric tonic neck primitive reflexes. Longitudinal or experimental studies should be conducted to reveal the causal relationship between ADHD and primitive reflexes in the future.

ABSTRACT
This study examined published articles concerning sports leadership within the sport psychology domain over the last 30 years using bibliometric analysis that centered on the written content of the publications as unit of analysis in order to explore the intellectual base, particularly the structural relationships among relevant research components about coach leadership. Leximancer version 5.0 (Leximancer Pty Ltd.) was used to extract data from 100 sports leadership-related articles from four sport psychology journals. Overall, the most relevant concepts generated were coaches (100%) and athletes (59%), followed by study, sport, support, and motivation, and behaviors. Also, relevant concepts produced for each journal were quite similar which included coaches, athletes, behaviors, study, support and team. Further, publications related to coach leadership have shown a steady growth rate since 1990 with 76% of all published articles were conducted via quantitative research method. Finally, United States, Canada, the United Kingdom, and Belgium were the top countries involved in the area of coach leadership. Coach leadership studies generally focus on behaviors and perceptions related to the coach and relationships between leadership and psychological outcomes. Each journal has a similar but distinct rationale when publishing papers about coach leadership. Bibliometric analysis can be applied as an alternative methodology to summarize large volumes of relevant data in order to map the current knowledge as well as identify potential future research directions.
ABSTRACT
This systematic review and meta-analysis aimed to systematically evaluate the effect of physical activity (PA) on inhibitory function in children with ADHD. Experimental studies on the effect of PA on the inhibitory function of children with ADHD were retrieved. The data were obtained from PubMed, The Cochrane Library, Web of Science, EBSCO (MEDLINE, APA Psyclnfo, ERIC), Embase, Scopus, and ProQuest. The search period was from the date of inception of the respective databases to 4 May 2022, and Reviewer Manager software (version 5.3) was used for analysis. Eleven articles and 713 samples were included in the meta-analysis. Results revealed that PA can significantly improve the inhibitory function of children with ADHD (SMD = 0.78, 95% CI: 0.45−1.10, p < 0.001). Subgroup analysis showed that the effectiveness of PA as an intervention in improving the inhibitory function of children with ADHD was moderated by the frequency, intensity, duration, type, and length of intervention. Based on the findings, PA can effectively improve interference suppression inhibitory function in children with ADHD. Longitudinal open-skill exercise for 60 min or more, two times/week has the best effect on improving inhibitory function in children with ADHD.

This study meta-analyzed the relationships between coach transformational leadership and player satisfaction and commitment. We also examined the potential moderating effect of player gender on these relationships. In total, 182 effect sizes were obtained from 26 studies comprised of 6,715 participants. The analyses revealed that the overall direct effect of transformational leadership was moderate on both athletic satisfaction and exercise commitment. The effect of charismatic construct of transformational leadership was moderate on athletic satisfaction as well as exercise commitment. Finally, player gender was found to moderate the effects of the relationship between transformational leadership and athletic satisfaction and exercise commitment of players. Specifically, female players' satisfaction and commitment were more positively affected by transformational leadership compared with their male counterparts. Our findings suggests that effective leadership in sports is dependent on the interaction among leadership behaviors of the coach, personal characteristics of the players, and situational factors and highlights the importance of transformational leadership as an important requirement for creating a more positive and sustainable sports environment.
ABSTRACT
Leaders play a significant role in organizations and their leadership behaviors can either enhance or undermine the well-being of their employees. This study aimed to meta-analyze the relationship between transformational leadership and well-being in the service industry, and how employees' gender and service sector moderated the strength of this relationship. This study used a convergent mixed-method approach. PubMed, MEDLINE, Google Scholar, AMED, and Scopus electronic databases were utilized to search for relevant studies. Textual data were analyzed using a text data-mining technique (Leximancer) to determine the relevant themes and concepts. Statistical data were examined through a comprehensive meta-analysis to determine their effect sizes. The qualitative results outline the major themes that emerged: leadership, well-being, and health. The quantitative findings revealed that the perceived well-being of male employees and those working outside of the health-care service sector was positively higher when employees' leaders showed transformational leadership. In general, the findings from the qualitative and quantitative data converge. The findings confirm the positive relationship between transformational leadership and employee well-being. This study also highlights the applicability of a convergent mixed-method approach as a useful methodological strategy when analyzing both lexical and statistical data.

This study aimed to meta-analyze the relationship between self-management and exercise self-confidence, satisfaction, and commitment in both modern and traditional martial arts among Korean practitioners. We examined the level of sports participation and different martial arts sports as potential moderating variables. In total, 22 studies yielded 299 individual effect sizes and were included in the final meta-analytic pool. The analyses revealed a moderate effect of self-management on exercise satisfaction and self-confidence; and a large effect self-management on exercise commitment. Especially, the effect of the training dimension of self-management was large on exercise commitment and satisfaction, while that of the mental dimension was large on exercise self-confidence. The effects of self-management on exercise satisfaction, commitment, and self-confidence were large in judo, Ssireum, and wrestling, respectively. Finally, the use of self-management was relatively more effective for non-elite participants than for elite practitioners. Our results highlight the effectiveness of self-management to enhance Korean martial arts practitioners' exercise self-confidence, commitment, and satisfaction, findings that may potentially be extended internationally and to other types of sports; further, they showcase the importance of the promotion of interventions and educational programs on how to incorporate/employ self-management in athletes' sports training.
ABSTRACT
The present study examined the attitudes of Filipino middle school students toward physical education (PE) and the associations between PE attitude and various personal and external correlates of PE. In total, 659 middle school students, aged between 12 and 19 years (M = 14.55; SD = 1.14), participated in the study. The Physical Education Attitude Scale (PEAS) was used to measure affective, cognitive, and motivational/behavioral attitudes of adolescent students toward PE. Results showed that middle school students had moderate general attitudes toward PE. Female students had more favorable attitudes toward PE when their teacher was male than female. When the teacher was female, male students were more satisfied with the PE curriculum than female students. When the teacher was male, female students were more comfortable with the PE curriculum than male students. Finally, students' PE attitude did not decrease as they got older, regardless of student sex. The findings provide a different perspective for the field and underscore the importance of not only the PE curriculum but also the student-teacher relationship. To prevent the decline in students' positive attitude and encourage positive behaviors toward PE and activities, teachers should be very considerate about their interactions with students of the same sex; school administrators (e.g., principal and PE department head), meanwhile, should focus at providing PE teachers with special training courses to enhance both their teaching and communication capabilities.
ABSTRACT
BACKGROUND: The purpose of this study was to examine the use of observational learning among athletes when they observed themselves (self-model) or their opponents (opponent-model). Furthermore, there was an emphasis on determining the relationships between age, experience, and the functions (i.e., skill, strategy, performance) of observational learning according to the type of model observed. METHODS: A total of 158 athletes (male=70, female=88) who competed in different team (N.=83) and individual (N.=75) sports participated in the study. They ranged in age from 17 years to 32 years. Their total years of sport participation ranged from one year to 18 years. RESULTS: Athletes reported significantly greater use of all three functions of observational learning for the self-model than for the opponent-model. Bivariate correlations revealed years of experience was significantly and positively associated with the skill, self, and performance functions of observational learning for the self-model. In contrast, age was significantly and positively related with the performance function of observational learning for the opponent-model. CONCLUSIONS: The finding provides the first empirical evidence to suggest that model type influences the use of observational learning in athletes. A positive relationship also exists between experience and self-observational learning as well as age and the opponent-performance function of observational learning. The results contribute to the observational learning literature and provide support to the Applied Model for the Use of Observation.

The authors investigated the coaching behavior preferences and the relationships of these preferences with variables such as gender, type of sport, playing experience, competitive level, and coach gender among young athletes in the national badminton league. Participants were 167 elementary and high school badminton players (91 girls and 76 boys; age range = 9-18 years; M = 13.5 (SD = 2.22) years) competing in the badminton event of a national league. Players' preferences for coaching behavior were measured using athlete preference version of the LSS to evaluate the five dimensions of leadership behavior in a sporting context. Notably, young athletes strongly preferred training and instruction, followed by positive feedback, democratic behavior, social support, and autocratic behavior. An interaction effect of athlete and coach gender on the leadership dimensions of democratic behavior, autocratic behavior, and social support was found. Male athletes with female coaches preferred more democratic behavior, autocratic behavior, and social support behavior than did those with male coaches. Conversely, female players with male coaches favored more democratic behavior, autocratic behavior, and social support than did those with female coaches. This study provides valuable insight into understanding the dynamics of sport leadership environments among young athletes, and how crucial is the role of coach's gender in the athlete-coach dyad interaction.

La presente investigación fue llevada a cabo con el propósito fundamental de identificar el Síndrome de Alcohol Fetal en los niños desnutridos que fueron tratados en la Clínica Nutricional del Instituto Dominicano de Alimentación y Nutrición, durante el período comprendido entre el 14 de enero y el 21 de febrero del año 1994, en el interés de conocer la dimensión de esta enfermedad, para de esta manera, poder ofrecer un marco de referencia riguroso, que permita un mayor conocimiento y un mejor tratamiento de dicho padecimiento. Para tales fines, seleccionamos, en forma casuística, un universo compuesto por los 453 pacientes que asistieron a la consulta del citado centro de salud, durante el período de referenda, en busca de tratamiento médico para resolver sus problemas nutricionales. Cabe destacar, que nuestra actuación en cada consulta, estuvo enmarcada dentro de la técnica conocida como Observación-participante, la cual nos permitió satisfactoriamente jugar un rol protagónico en la detección de la enfermedad. De cada 453 pacientes de problemas nutricionales, 15 de ellos presentaron estigmas correspondientes al Síndrome de Alcohol Fetal, para una frecuencia relativa de un 3.3//. El 93.3// de los casos, exhibió el filtrum hipoplástico, mientras que en el 66.7//, se verificó la existencia de labios con bordes delgados presentandose, por último, la micrognatia en el 60// de la población muestral. Todas las madres de estos pacientes admitieron haber consumido bebidas alcoholicas de manera regular y consistente durante el período de gestación, llegando incluso, a ingerir desde una cerveza hasta cinco tragos de ron diariamente
