Introduction/objective:

The present study aimed to examine the relationship be tween transformational coach leadership with the characteristics of resilience and vulnerability under pressure, as well as to analyze whether the factors of intra-group conflict (social and task) and group cohesion (social and task) could mediate the relationship between these variables.

Method:

Through a longitudinal design, a total of 301 athletes enrolled in the JUDEX, belong ing to 34 soccer and volleyball teams, and aged between 13 and 18 years (M = 15.72; SD = 1.33).

Results:

The results showed a positive relationship between transformational leadership of the coach and resilience characteristics, and a negative association with respect to vulnerability under pressure. In addition, intra-group conflict (social and task) acted as mediators between the relationship between transformational coach leadership and team resilience. Regarding the mediating role of group cohesion, only task cohesion acted as a mediator between trans formational coach leadership and team resilience.

Conclusions:

This research draws as main conclusion the importance of the coach’s leadership to improve team resilience in youth cate gories, and the positive influence of the reduction of intragroup conflicts and the increase of task cohesion during the season.
