This study aimed to analyze the association between specific dimension (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) of students' physical self-concept (PSC) and their physical activity (PA) levels (i.e., intentions to be physically active and out-of-school PA levels perceived by students) and sedentary behavior (SB) (i.e., total sitting and screen time perceived by students). We also tested the role of students' motivation (i.e., intrinsic motivation and amotivation) towards PA in these relationships. A total of 1998 Spanish male (n = 1003) and female (n = 995) secondary students, aged between 13 and 17 years (M = 14.92, SD = 0.87) from 22 schools, enrolled in third grade (n = 1081) and fourth grade (n = 917), completed the self-reported questionnaires. Five independent structural equation modeling (SEM) adjusted by students' sex was used to examine the association between specific dimension of students' PSC (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) and self-reported PA and SB variables, and to test the role of students' motivation in these relationships. Overall, most of students' PSC dimension positively predicted students' PA outcomes, and were negatively associated with SB. In addition, most of students' PSC dimension were positively associated with intrinsic motivation, and negatively predicted amotivation. In turn, intrinsic motivation was a positive predictor of PA outcomes, and a negative predictor of SB, whereas amotivation was a negative predictor of PA outcomes and sitting time, and a positive predictor of screen time. Finally, from PSC dimensions, sex as a covariate was a positive predictor of intrinsic motivation and PA outcomes, and was a negative predictor of amotivation and sitting time. These findings suggest the importance of the specific dimensions of PSC perceived by adolescents on their motivational processes, and in turn, on their PA and SB outcomes.

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.Highlights We 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.

Background: The aim of this systematic review was to examinemotivational interventions based on physical activity as precursor of psychosocial benefits inside of the scholar context. Method: studies were identified in seven databases (Web of Science, Sport Discuss, Scopus, Eric, Pubmed, Psycinfo and Google Scholar). The search process was from June 2011 to September 2019. A total of 41 articles met the inclusion criteria. Results: 23 studies showed psychological effects after intervention and also 10 studies showed psychosocial effect after the intervention. The rest of the studies, although they presented changes, did not become significant.Conclusions: this systematic review showed the importance of motivational processes for the performance of physical activity and sport as a precursor of psychosocial changesand highlights the importance of strategies and the temporal nature of studies to maintain significant changes over time.Likewise, the study shows the future trend of motivational interventions, highlighting the female gender as participants of special interest, and changing the methodology through web-based interventions and active breaks or mental breaks during traditional subject classes.

Framed within Self-Determination Theory, the objective of this study was to analyze the relationship between satisfaction and frustration of basic psychological needs, levels of motivation, physical activity, and satisfaction with life. METHODS: A total of 487 students participated, comprising males (n = 262) and females (n = 225), aged between 14 and 16 years (M = 15.02; SD = 0.87), from different secondary schools. RESULTS: A regression analysis was carried out (structural equation modeling) that revealed the existence of two theoretical lines, one positive and the other negative, where the satisfaction of basic psychological needs was positively related to autonomous motivation and physical activity, which predicted satisfaction with life. On the other hand, the frustration of basic psychological needs was positively related to controlled motivation, whereas controlled motivation (introjected regulation and extrinsic regulation) was inversely associated with physical activity and satisfaction with life. CONCLUSION: The results show the importance of motivational processes in physical activity, and the effects of physical activity on satisfaction with life in adolescents who spend more time engaged in physical activity.

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.

Grounded in self-determination theory, this study aimed first to examine differences in motivation for physical activity (PA) and habitual PA levels between adolescents and university students in Spain. The second aim was to examine differences in the degree of association between their intrinsic motivation and amotivation for PA and habitual PA levels in both samples. We studied 2,699 students (1,833 high school and 866 university; mean age = 18.83, standard deviation = 4.12 years) who completed the International Physical Activity Questionnaire-Short Form and two dimensions of the Behavioral Regulation in Exercise Questionnaire. High school students, relative to university students, self-reported significantly higher intrinsic motivation and higher PA levels for each type of PA intensity (i.e., walk, moderate, and vigorous); high school students also self-reported significantly lower amotivation than university students. The degree of association between the total metabolic equivalents of task and intrinsic motivation was higher among high school (versus) university students. This study shows the need to design intervention strategies to enhance PA levels and intrinsic motivation in university students.

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.
