ABSTRACT
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.

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.
ABSTRACT
Mental load and fatigue are important causes of performance decreases and accidents in different activities. However, a robust systematic review, detailing the instruments used to quantify them, is currently lacking. The purpose of this study was to summarize and classify by derivations the validated instruments used to quantify mental load and fatigue. The most representative electronic databases in the scope of this review, PubMed, WOS, Scopus, SPORTDiscus, and PsycINFO (until September 2020) were searched for studies that included instruments to analyze mental load and fatigue. The quality of the selected studies was scored using a quality assessment checklist. A total of 40 papers were included. Most of the papers used subjective scales (75%) to quantify mental load and fatigue, with a small presence of behavioral (n = 5) and objective techniques (n = 5). Less is known about the analysis of mental load and fatigue using a combination of derivations. Despite the high cost and complexity of objective techniques, research that applies these measures is important for further analysis of brain processes in mental load and fatigue. The design of a battery of tests that include the three types of derivations also seems necessary.
