Leadership is a necessary construct associated with the ability to influence people to achieve goals. This research aimed to evaluate the predominant styles in a sample of 74 high-level coaches from 14 countries and six sports, using non-probabilistic convenience criteria. A multifactorial instrument was administered to assess transactional, laissez-faire, and transformational styles, aligned with modern leadership trends, and their relationships with the coaches’ ability to lead teams at a high level. Descriptive and inferential analysis techniques, including exploratory factor analysis, were applied. It was determined that the predominant style among coaches was transactional, followed by transformational. Coaches’ gender did not influence significant differences in style, but it did influence the coaches’ perception of their ability to achieve sporting results. The dimensions most highly perceived by coaches were contingent reward, associated with the transactional style, and the ability to manage, plan, and achieve sporting results. The transformational style has the most significant influence on team leadership ability, followed by the transactional style. Factor analysis revealed the formation of four factors, only one of which shows evidence of a link between transformational leadership and specific emotional and motivational aspects of sports teams.
