How class cohesion and teachers' relatedness supportive/thwarting style relate to students' relatedness, motivation, and positive and negative outcomes in physical education.

The main goal of this study was to examine the links between class cohesion and teachers' relatedness teaching style with students' relatedness needs, motivation, and positive and negative outcomes in Physical Education. A total of 1294 students 10-18 years old (M = 14.40, SD = 1.99), 613 males (M = 14.48, SD = 1.95) and 681 females (M = 14.33, SD = 2.02), agreed to participate. They were enrolled in 88 classes belonging to 13 different primary and secondary schools in southwestern Spain. The study followed a correlational research design. Results of the multilevel path model showed a positive relationship between teachers' relatedness support and class cohesion and behavioral and emotional engagement through relatedness need satisfaction and autonomous and controlled motivation. Results also showed a positive relationship between teachers' relatedness thwarting and disruptive behaviors and problematic relationships through relatedness need frustration and amotivation. In conclusion, teachers' relatedness behaviors and class cohesion can significantly impact the students' relatedness and motivation, which in turn will affect their engagement and behaviors. A whole cascade of consequences begins with the way teachers teach and the cohesion generated in class. These first steps cannot be overlooked.

Teachers' Verbal and Nonverbal Communication, Students' Psychological Needs, and Positive and Negative Outcomes in Physical Education.

Focused on physical education (PE), this study examined the association between teachers' communication and students' psychological needs, enjoyment/boredom, PE usefulness, and students' grade perception. Participants were 1,000 students (572 girls; Mage = 14.58 ± 0.65) from 29 Spanish secondary schools. A path model including variables measured at three times was tested: teachers' verbal/nonverbal communication (Time 1), needs satisfaction/frustration (Time 2), and PE outcomes (Time 3). Verbal communication positively predicted needs satisfaction, which, in turn, positively predicted enjoyment, PE usefulness, and students' grade perception and negatively predicted boredom. Verbal communication negatively predicted needs frustration, which was a positive predictor of boredom. Multigroup analysis showed that gender did not moderate the associations in the path model, whereas mediating effects were found between teachers' communication and consequences via students' psychological needs. Teachers should improve their communicative capacities to satisfy students' psychological needs and promote positive PE  outcomes.

Effects of out-of-school physical activity interventions based on self-determination theory in children and adolescents: A systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to examine the effects of out-of-school physical activity (PA) interventions, based on Self-Determination Theory (SDT), on basic psychological needs (BPN), motivation toward PA, and PA levels in youths. DESIGN: Systematic review and meta-analyses. METHOD: We searched for intervention studies examining the effects of PA interventions based on SDT implemented outside the school published in English and Spanish in six electronic databases up to January 2022. RESULTS: Outcomes of interest were BPN, motivation, and PA levels. In total, nine studies were included in this review. Seven individual meta-analyses were conducted for each variable, revealing nonsignificant clustered effects for the outcomes autonomy satisfaction (g = 0.12, 95% CI [-0.31, 0.55]), competence satisfaction (g = 0.02, 95% CI [-0.28, 0.32]), relatedness satisfaction (g = 0.13, 95% CI [-0.43, 0.68]), autonomous motivation (g = 0.15, 95% CI [-0.38, 0.67]), controlled motivation (g = 0.12, 95% CI [-0.32, 0.55]), amotivation (g = -0.36, 95% CI [-0.88, 0.16]), and PA behavior (g = 0.02, 95% CI [-0.08, 0.12]). CONCLUSION: Meta-analyses suggest that out-of-school PA interventions based on SDT are not effective in increasing levels of needs satisfaction, types of motivation, and PA levels.

Is coaches' perceived team performance associated with their intentions to persist in coaching? The mediating role of coaches' psychological needs and motivation.

This study examined the association between team performance perceived by coaches, coaches' basic psychological needs, motivation, and their intentions to persist in coaching. Participants were 719 coaches (80 females, M = 33.49 years, SD = 10.27, range = 18-67) of different team sports (soccer = 514; basketball = 165; volleyball = 23; handball = 14; and hockey = 3) who completed questionnaire measures at the end of the season. Structural equation modelling adjusted for sex, coaches' experience, age categories, and type of sport revealed that coaches' perceptions of team performance were positively related to their need satisfaction and negatively to their need frustration. In turn, coaches' need satisfaction was positively associated with their autonomous motivation, whereas their need frustration was positively related to controlled motivation and amotivation. Finally, coaches' autonomous motivation was a positive predictor of their intentions to persist, and conversely, coaches' amotivation was a negative predictor of their intentions to persist. We found a significant positive and indirect effect between team performance perceived by coaches and their intention to persist through their need satisfaction and autonomous motivation. These findings represent the first quantitative insight into how coach-perceived team performance could function as a new antecedent relevant to coaches' motivational processes and persistence.

An intervention program based on team building during tactical training tasks to improve team functioning.

The study aimed to analyze the effects of an intervention program based on team building developed in technical-tactical training tasks in football. Specifically, it examined the benefits of the intervention in variables related to the conceptual model of team building: role clarity, team identification, intra-team communication, cohesion, intra-group conflict, commitment to the team, inside sacrifice, transactive memory systems, collective efficacy, and perceived performance. The participants were 51 young elite footballers divided into an experimental group (n = 27) and a control group (n = 24). The methodological design was quasi-experimental with a duration of 8 weeks. The data were collected three times: pretest, posttest, and follow-up. The results showed differences favoring the experimental group compared to the control group after the implementation of the intervention program in the following variables: team identification (p < 0.001), role clarity (p < 0.001), intra-team communication (p < 0.001; except distinctiveness), group cohesion (p < 0.05), social conflict (p = 0.001), commitment to the team (p < 0.001), inside sacrifice (p < 0.001), transactive memory systems (p < 0.01; except coordination), collective efficacy (p = 0.02) and team performance (p = 0.001). Consequently, the application of team-building strategies incorporated into specific technical-tactical training tasks in football seems to improve group dynamics in sports teams.

The relationship among intra-group communication, transactive memory systems, collective efficacy and team performance: A structural equation model analysis with Elite Footballers.

We explored the relationship among intra-group communication, collective efficacy, transactive memory systems and team performance. One hundred and seventy soccer players, aged between 14 and 38 years (M = 18.35, SD = 4.71), from eight national teams participated in this study. Data were analyzed using structural equation modeling. First, our analysis revealed that intra-group communication was positively related to transactive memory systems. Second, transactive memory systems was positively associated with collective efficacy and team performance. Third, our analysis revealed that collective efficacy mediated the relationship between transactive memory systems and performance. Altogether, our findings advance the literature by highlighting the relationship among intra-group communication, collective efficacy, transactive memory systems and team performance team processes. From an applied perspective, our findings suggest that systemic interventions simultaneously targeting various team constructs are important to enhance team functioning.Highlights The relationship among intra-group communication, collective efficacy, transactive memory systems and team performance were examined in national football teams.A cross-sectional design was developed and the data were analyzed using structural equation modeling.Players perceptions of high intra-group communication were positively associated with the development of transactive memory systems.Higher levels of transactive memory systems and collective efficacy were associated with better team performance.

Do sport teams with greater team resilience perceive higher performance at the end of the season? A multilevel analysis.

A team's ability to respond positively to adversities, problems, and obstacles during their season is an essential part of success in collective sports. Grounded in team resilience theory and using a multilevel analytical approach, this study examined the relationship of the characteristics of resilience and vulnerability under pressure with perceived individual and team performance. Participants were 676 soccer players (530 males and 146 females) aged 15-42 years (M = 21.40, SD = 5.38), who played on 64 senior and under-18 soccer teams of several national leagues in Spain. In the final month of the season, factors related to team resilience and individual and team performance were analyzed. We estimated multilevel models by including perceived individual and team performance as dependent variables. Characteristics of resilience and vulnerability under pressure were considered as fixed and random effects (i.e., individual- and team-level intercepts and slopes). At the individual level, results showed that characteristics of resilience were positively associated with subjective individual and team performance, whereas vulnerability under pressure was negatively related to perceived team (but not individual) performance. At the team level, only characteristics of resilience positively predicted team performance. These findings suggest that more resilient teams report more successful performance from an individual and team perspective, whereas teams that are more vulnerable under pressure report poorer team performance. Taken together, the study underscores the importance of practitioners to develop strategies that improve their teams' resilience, given that team resilience helps to achieve positive subjective individual and team outcomes.

KIDMED 2.0, An update of the KIDMED questionnaire: Evaluation of the psychometric properties in youth.

Background and aims: As children and adolescents' eating patterns have changed over the last few years, researchers have found inconsistencies in the current questionnaires. Therefore, this research aims to (i) update the 2019 KIDMED questionnaire; and (ii) test the psychometric properties of this new questionnaire. Method: A study with 419 children and adolescents in southwestern Spain was conducted in 2021. The new version of the KIDMED 2.0 was tested, which measures adherence to the Mediterranean diet through 16 items, of which 12 are positive, and 4 are negative. Content validation involved consultation with nutritionists, experts, and adolescents to assess whether the questionnaire was reliable and valid regarding dietary patterns associated with the Mediterranean diet. The expert assessment provided content validity indices for the clarity and representativeness of the questionnaire. Construct validity and test-retest reliability involved 419 students (M age = 14.40 ± 2.00) from southwestern Spain. Students responded twice (one week apart) to the KIDMED developed in the previous stage and completed a 7-day dietary record. Results: Regarding validity, results show a moderate agreement for 10 items (ranging between 0.21 and 0.47) of the KIDMED and the 7-day dietary record. Concerning Items 3, 4, 5, and 6, the agreement was slight (ranging between 0.08 and 0.17), whereas the agreement for Item 8 was low. Cohen's kappa showed that most items had moderate to substantial test-retest reliability. Also, kappa showed significant test-retest values for all items (p < 0.001). Conclusion: The new version of the KIDMED 2.0 was shown to be a reliable and valid instrument to measure adherence to the Mediterranean diet in children and adolescents.

Are Teams Whose Players Are More Committed To the Team More Resilient? the Role of Intra-Group Conflict.

The study aimed to analyze the relationship between commitment to the team and team resilience factors (characteristics of resilience and vulnerability under pressure), and to examine whether the task and social intra-group conflict act as mediators between commitment to the team and team resilience factors. One hundred seventy (170) male soccer players (16-38 years; M = 18.35; SD = 4.72) of the national teams of Argentina, Costa Rica, and Mexico participated in the study. The path analytic model was used to test mediating pathways. First, the results revealed that commitment to the team was positively related to characteristics of resilience and negatively to vulnerability under pressure. Second, bootstrap mediation analysis showed that athletes' perceptions of the task and social intra-group conflict mediated the association between their perception of commitment to the team and team resilience factors. Findings provide initial evidence for a link between commitment to the team and team resilience in national teams and also suggest that intra-group conflict can improve the association between commitment to the team and team resilience. Therefore, the main conclusion of this study is that practioners should promote players' commitment to the team and avoid intra-group conflicts within teams to have a resilient team that copes with problems more easily.

Relación entre los conflictos intra-grupo y el rendimiento en deportes colectivos: efecto mediador de la eficacia colectiva / Relação entre conflitos intra-grupo e desempenho em esportes coletivos: efeito mediador da eficácia coletiva / Relationship between intra-group conflicts and performance in collective sports: mediator effect of collective efficacy

El presente estudio tuvo como objetivo analizar la relación entre el conflicto intra-grupo y el rendimiento percibido a final de temporada, y examinar como actúa la eficacia colectiva como variable mediadora en esta asociación. Participaron 420 jugadores semi-profesionales y amateurs (M = 22,40; DT = 4,71) de baloncesto, balonmano, fútbol y voleibol. Los resultados mostraron que el conflicto intra-grupo (tarea y social) se relacionó negativamente con el rendimiento percibido del equipo, y que la eficacia colectiva mostró resultados significativos actuando como mediadora entre la relación de el conflicto intra-grupo (tarea y social) y el rendimiento percibido del equipo. Por lo tanto, es importante destacar que los conflictos intra-grupo parecen empeorar las percepciones sobre el rendimiento grupal y que la eficacia colectiva puede suavizar esta relación negativa, consiguiendo un aumento en el la percepción de los jugadores sobre el rendimiento del equipo a final de temporada. (AU)

The present study aimed to analyze the relationship between intra-group conflict and team perceived performance at the end of the season, and to examine the mediating effect of collective efficacy on this relationship. 420 semi-professional and amateur players (M = 22,40; SD = 4,71) of basketball, handball, soccer and volleyball participated. The results showed that intra-group conflict (task and social) was negatively related to team performance and collective efficacy showed significant results acting as a mediator between the relationship of intra-group conflict (task and social) and team perceived performance. Therefore, it is important to highlight that intra-group conflict seems to worsen the collective functioning and that collective efficacy can soften this negative relationship, achieving an increase in team performance at the end of the season. (AU)

O presente estudo teve como objetivo analisar a relação entre conflito intra-grupo e desempenho percebido no final da temporada, e examinar como a eficácia coletiva atua como uma variável mediadora nesta associação. Participaram 420 jogadores semiprofissionais e amadores (M = 22,40; DT = 4,71) de basquete, handebol, futebol e voleibol. Os resultados mostraram que o conflito intra-grupo (trabalho de casa e social) estava negativamente relacionado ao desempenho percebido da equipe e que a eficácia coletiva apresentou resultados significativos atuando como mediador entre a relação do conflito intra-grupo (trabalho de casa e social) e o desempenho percebido da equipe. Portanto, é importante destacar que o conflito intra-grupo parece agravar o funcionamento coletivo da equipe e que a eficácia coletiva pode amenizar essa relação negativa, conseguindo um aumento na percepção do desempenho da equipe no final da temporada.

Does coaches' satisfaction with the team determine their interpersonal style? The mediating role of basic psychological needs.

The purpose of the present study was to examine how coaches' satisfaction with the team could be related to their reported interpersonal style towards young athletes, and to analyze the mediating role of basic psychological needs (i.e. need satisfaction and need frustration) in this relationship. Participants were 352 coaches (16-67 years old; Mage = 32.88, SD = 11.14) from 48 clubs, who had between 1 and 52 years of training experience (M = 23.23, SD = 15.02). Structural equation modelling (SEM) was employed to test the relationships between variables. Results showed that satisfaction with the team is positively related to coaches' need satisfaction, and negatively to their need frustration. Need satisfaction positively predicted coaches' need-supportive style, and need frustration predicted their need-thwarting style. Regarding indirect effects, need satisfaction positively mediated the relationship between coaches' satisfaction with the team and their need-supportive style, and need frustration negatively mediated the relationship between coaches' satisfaction with the team and their need-thwarting style. These findings are a first step to highlight satisfaction with the team as an antecedent of coaches' self-reported need-supportive and need-thwarting behaviours towards athletes, and the mediating role of coaches' psychological needs (need satisfaction and need frustration) in this relationship.HighlightsWe examined the satisfaction of the team as antecedent of coaches' interpersonal style.We tested the mediating role of coaches' psychological needs in this relationship.Satisfaction with the team was positively related to need-supportive style.Satisfaction with the team was negatively associated with need-thwarting behaviors.Coaches' psychological needs mediated the relationship between team satisfaction and their interpersonal style.

Is Perceived Athlete Leadership Quality Related to Inside Sacrifice and Perceived Performance in Team Sports? The Mediating Role of Team Identification.

The study aimed to analyze the relationship between athletes' perceptions of athlete leadership quality, team identification, inside sacrifice, and performance. A total of 299 players of collective sports (soccer, beach soccer, basketball, volleyball; M age 19.05, SD = 5.10) participated through a cross-sectional design survey. Data were analyzed using structural equation modeling. Results highlight the positive relationships between perceived quality of athlete leaders, inside sacrifice, and perceived performance, and between inside sacrifice and perceived performance. Furthermore, inside sacrifice perceived by the athletes was a positive mediator between perceived athlete leadership quality and perceived performance. Also, team identification was a positive mediator in the association between inside sacrifice and perceived performance. These findings extend knowledge about the athlete leadership quality context. These results can also be useful for further research and implications in team sports' performance, as coaches and sports psychologists would have more information about their teams' perceptions of leadership quality to achieve positive outcomes in players' inside sacrifice and performance. The findings also highlight the importance of developing team identification to improve the relationships between perceived athlete leadership quality, inside sacrifice, and perceived performance.

Understanding Physical Activity Intentions in Physical Education Context: A multi-level Analysis from the Self-Determination Theory.

Using self-determination theory as a framework, we aimed to study the relationships between perceived need support and need satisfaction with self-determined motivation and extracurricular physical activity intentions in the physical education (PE) classroom, including sex and out-of-school sport participation as moderators. Additionally, we aimed to test whether a need-supportive classroom environment in PE moderates these associations. Participants were 1259 students (556 males) aged between 12 to 16 years (Mage = 13.46 years; SD = 0.74) from 77 PE classes. At the student level we found (a) need satisfaction to predict positively autonomous motivation and negatively amotivation, and (b) autonomous motivation to predict positively and amotivation to predict negatively intentions to undertake extracurricular physical activities. At the classroom level, in need-supportive classes males benefit more than females in terms of increased autonomous motivation while females benefit more than males in terms of decreased amotivation. Finally, class-level perceived need support moderated (i.e., attenuated) the negative association between need satisfaction and amotivation and between amotivation and intentions. These results suggest a buffering role that a need-supportive classroom environment may have on students' motivation and behavior.

How many leaders does it take to lead a sports team? The relationship between the number of leaders and the effectiveness of professional sports teams.

This study aimed to analyze the number of task, social and external athlete leaders within sports teams, and to examine the effectiveness of different leadership structures in male and female teams. The participants were 317 male and 214 female soccer players belonging to 18 teams playing in the third highest male division and to 13 teams playing in the highest female division in Spain, respectively. First, we identified the leadership structure in each team (i.e., having zero, one, two or three leaders); second, we grouped the teams according to these leadership structures; and third, MANOVA was used to compare different leadership groups in terms of their effectiveness. The results demonstrated that: (a) the most common structure within the teams was to have one task leader, one social leader, and two external leaders; (b) shared leadership across and within leadership roles was seen as the most effective leadership structure for male and female teams; and (c) male teams showed more benefits when having more task and external leaders, while female teams experienced more benefits when having more task and social leaders on the team. Based on these findings, coaches can optimize their team's functioning by implementing a structure of shared leadership within their teams, both across and within the different leadership roles.

Effects of an intervention with teachers in the physical education context: A Self-Determination Theory approach.

Framed within Self-Determination Theory, the purpose of the present study was to test the effects of a training program with physical education (PE) teachers. Participants were 21 high school PE teachers (experimental group, n = 10; control group, n = 11), and their 836 students, aged 12 to 16 years. Teachers in the experimental group received a training program consisting of strategies to support autonomy, competence, and relatedness need satisfaction. A repeated measures ANCOVA was carried out for each dependent variable. After the intervention, students in the experimental group significantly increased their scores on autonomy support, relatedness support, autonomy satisfaction, autonomous motivation, controlled motivation, and intention to be physically active, as compared to the control group. These findings emphasize the utility of a training program with PE teachers to promote the students' psychological need satisfaction, and hence, self-determined motivation toward PE classes.

Effects of an Interpersonal Style Intervention for Coaches on Young Soccer Players' Motivational Processes.

The main goal of the study was to assess the effects of an intervention programme developed with soccer coaches, based on promoting strategies to optimise the satisfaction of the basic psychological needs of athletes. Eight soccer coaches, aged between 19 and 50 years (M = 32.5; SD = 14.34), participated in the study. They were selected intentionally (without academic or federative training) and divided equally into a control and an experimental group by random peer selection. Also, 109 soccer players, aged between 11 and 15 years (M = 13.78; SD = 1.38), divided into a control group (CG; n = 56) and an experimental group (EG; n = 53), participated in the experiment. The training programme (12 hours) was aimed to develop methodological and motivational strategies to promote autonomy, competence and relatedness need satisfaction among the players. The results showed that the participants in the EG decreased competence and relatedness control, while significantly increased (post-intervention) competence and relatedness needs satisfaction. Moreover, values for the EG did not decrease for autonomy, competence frustration and amotivation, while they increased for the sport commitment. Also, intrinsic motivation decreased in both groups (greater decrease in the CG). In conclusion, we can affirm the effectiveness of the training programme to create an environment of "bright side" motivation, and reduce thwarting styles, needs frustration and low self-determination levels.

Frustración de las necesidades psicológicas, motivación y burnout en entrenadores: incidencia de la formación / Thwarting of need frustration, motivation and Burnout in coaches: incidence of teaching / Frustraçao das necessidades psicológicas, motivaçao e Burnout em treinadores: incidencia da formaçao

El objetivo del estudio era analizar la incidencia de la formación (federativa y académica general) de los entrenadores sobre variables psicológicas motivacionales (frustración de las necesidades psicológicas básicas (NPB), autodeterminación), eficacia profesional y agotamiento emocional. Para ello, participaron 147 entrenadores de 26 deportes diferentes en categorías de iniciación. Los resultados demostraron que los entrenadores con titulación deportiva intermedia tenían una motivación más intrínseca que los no cualificados, mientras que los entrenadores con mayor titulación se sentían más eficaces y más agotados. Asimismo, los entrenadores con mayor titulación académica general obtuvieron menores niveles de frustración en las NPB de competencia y relaciones sociales. Por tanto, la cualificación de los entrenadores determina los niveles de frustración de las NPB, el grado de motivación y dos dimensiones del burnout, la eficacia profesional y el agotamiento emocional

The aim of this study was to examine coaches' training (federative and general academic) incidence on motivational psychological variables (frustration of the basic psychological needs (BPN), self-determination, professional efficacy and emotional burnout). Thus, 147 coaches belonged to 26 different sports in training categories participated in the study. Results showed that coaches with medium sport qualification had a greater intrinsic motivation than those who were not qualified, whereas coaches with higher qualification showed more efficacy and burnout. Moreover, coaches with greater general academic degree had low levels of frustration in the BPN of competence and relatedness. Therefore, coaches’ qualification determine their frustration of the BPN, level of motivation and two burnout dimensions, professional efficacy and emotional burnout

O objectivo deste estudo foi analisar a incidência da formação de treinadores (federativa e académica geral) nas variáveis psicológicas motivacionais (frustração das necessidades psicológicas básicas (NPB), autodeterminação, eficácia profissional e burnout emocional). Assim, participaram no estudo 147 treinadores dos escalões de formação de 26 modalidades desportivas diferentes. Os resultados mostraram que os treinadores com qualificação desportiva média tinham maior motivação intrínseca do que aqueles que não eram qualificados, enquanto os treinadores com maior qualificação apresentaram maior eficácia e burnout. Adicionalmente, treinadores com maior grau académico geral tinham baixos níveis de frustração das NPB de competência e relação. Como tal, a qualificação dos treinadores determina a frustração das suas NPB, o nível de motivação e duas dimensões de burnout, eficácia profissional e burnout emocional

¿Apoyan los entrenadores la motivación de sus deportistas? Diferencias en la percepción del comportamiento / Do coaches support their athletes motivation? Differences in the perception of behavior / Os treinores fomentam a motivação dos seus atletas? diferenças na percepção do comportamento

The aim of this study was focused on assessing the influence of perception of support for basic psychological needs (BPN) on variables such as intrinsic motivation, enjoyment, boredom, and intention to persist in the training sport context; and how this can affect the difference between what is provided and what coaches believe athletes perceive in relation to such support. To achieve this aim, two different studies were conducted. In the 1st study, 985 athletes participated (M = 14.34; SD = 2.52), and a regression analysis was performed, where the results showed the importance of perception of support for BPN in the variables analyzed. Regarding the outcomes found in the former section, the 2nd study was carried out, where 91 coaches (M = 32.41; SD = 6.51) and 432 athletes (M = 13.44; SD = 2.92) were involved, and an analysis of differences was conducted after the creation of groups of coaches formed with respect to the support given and the support perceived by athletes. The results show differences in intrinsic motivation, boredom and intention to persist between athletes whose coaches were believed to give more support for BPN than perceived by athletes, with respect to participants whose coaches were considered to give support similar to or lower than the perceived. Therefore, the outcomes found have relevant implications to explain sport adherence in training stages, as well as the consideration of motivational background in a sport context

El objetivo de este trabajo era valorar la influencia de la percepción de apoyo a las necesidades psicológicas básicas (NPB) sobre la motivación intrínseca, disfrute, aburrimiento e intención de persistencia en el contexto deportivo de base, y como podía incidir la diferencia entre lo que los entrenadores creían proporcionar y lo que los deportistas percibían, en relación a dicho apoyo. Para ello, se llevaron a cabo 2 estudios diferentes. En el estudio 1 participaron 985 deportistas (M = 14.34; DE = 2.52) y se realizó un análisis de regresión, en el que se demostró la importancia de las percepciones de apoyo a las NPB sobre las variables analizadas. En función de estos resultados, se llevó a cabo el estudio 2, en el que participaron 91 entrenadores (M = 32.41; DE = 6.51) y 432 deportistas (M = 13.44; DE = 2.92), realizándose un análisis de diferencias entre grupos de entrenadores creados en función de la percepción de apoyo proporcionado y el apoyo percibido por los deportistas. Los resultados demostraron diferencias en la motivación intrínseca, aburrimiento e intención de persistencia entre los deportistas cuyos entrenadores creían proporcionar más apoyo a las NPB que el percibido por los atletas, respecto a aquellos cuyos entrenadores consideraban realizar un apoyo similar o inferior al percibido. Por tanto, los resultados hallados tienen implicaciones relevantes para explicar la adherencia deportiva en etapas de formación y en la consideración de los antecedentes motivacionales en el contexto deportivo

O principal objectivo do presente estudo foi avaliar a influência da percepção de apoio às necessidades psicológicas básicas (NPB) emvariáveis como a motivação intrínseca, divertimento, aborrecimento e intenção para persistir no treino desportivo, e como isso pode afectar as diferençasentre o que fornecem e o que pensam os treinadores que os atletas percepcionam no que concerne a esse apoio. Para alcançar este objectivo, foramdesenvolvidos dois trabalhos. No primeiro estudo participaram 985 atletas (M= 14.34; DP= 2.52), e foi realizada uma análise de regressão sendo queos resultados demonstraram a importância da percepção de apoio às NPB nas variáveis analisadas. Tendo em conta os resultados obtidos no estudoanterior, o segundo estudo foi levado a cabo com a participação de 91 treinadores (M= 32.41; DP= 6.51) e 432 atletas (M= 13.44;DP= 2.92), e umaanálise de diferenças efectuada após a criação de grupos de treinadores formados com base no critério de apoio prestado e o apoio percebido pelosatletas. Os resultados revelam diferenças na motivação intrínseca, aborrecimento e intenção de persistir entre atletas cujos treinadores acreditavamfornecer mais apoio paras as NPB que o percepcionado pelos atletas, relativamente aos participantes cujos treinadores consideravam fornecer igual ouinferior apoio ao percepcionado. Contudo, os resultados obtidos apresentam implicações relevantes na explicação da adesão às etapas do treino desportivo,bem como relativamente à consideração de antecedentes motivacionais no contexto desportivo

Self-determination in teaching formative basketball players and its influence on respect to rules and opponents

El objetivo del presente estudio era analizar los comportamientos adaptativos de jugadores de baloncesto en etapas de formación en función de sus motivaciones para realizar la práctica deportiva. Para ello, han participado 284 jugadores federados de baloncesto, de entre 11 y 16 años de edad de la región de Extremadura. Para el análisis de los resultados se ha utilizado el programa estadístico SPSS 19.0 y se han realizado el análisis descriptivo, de correlaciones y de regresión lineal por bloques. Los resultados más importantes del estudio muestran que los jugadores con motivaciones más autodeterminadas, como la motivación intrínseca e identificada, muestran mayores conductas adaptativas, como son el respeto a las reglas y a los adversarios. Finalmente, se debe fomentar la práctica deportiva de los jóvenes jugadores de baloncesto desde regulaciones más intrínsecas para que el deporte en estas edades sea algo más que deporte y sirva de aprendizaje y transmisión de valores sociales (AU)

The aim of this study was to examine adaptive behaviors in teaching formative basketball players with regard to their motivations to play. Hence, 284 federative basketball players, ranging in age from 11 to 16 years old from the Region of Extremadura took part in the study. Descriptive analysis, correlation analysis and lineal regression analysis were conducted with SPSS 19.0 statistical program. Results showed that more self-determined players had greater adaptive conducts, such as respect to rules and opponents. Finally, it is noteworthy to provide intrinsic regulations in youth basketball players to create a good learning and promotes social values (AU)

The Importance of Parents' Behavior in their Children's Enjoyment and Amotivation in Sports.

The main aim of the research was to examine the relationship between motivational orientations and parents' behavior with regard to the players' motivational orientation, motivational climate, enjoyment and amotivation. The sample comprised 723 athletes (M = 12.37, SD = 1.48) and 723 parents (M = 46.46, SD = 2.56). Players were male and female who belonged to federative basketball, handball, football and volleyball teams. Parents and athletes completed questionnaires that assessed motivational orientations, parents' involvement in the practice as well as enjoyment and motivation in the sport. Results showed a positive relationship between parents' support of the sport and players' enjoyment and a negative relationship with players' amotivation. Moreover, in players who perceived more pressure from their parents, there was a positive association with amotivation and a negative one with enjoyment. Lastly, it was emphasized that appropriate parental participation can promote an increase of players' enjoyment of and motivation for sport.
