RESUMO
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.
RESUMO
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.

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.

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.
