This scoping review aimed to identify the current state of knowledge on toxic leadership in high-performance sports and its consequences for mental health and performance at individual, interpersonal, and organizational levels. Abstract screening (n = 768) and full-text review (n = 83) resulted in the inclusion of 26 studies, predominantly conducted in North America and Europe. Studies used inconsistent definitions, theoretical frameworks, and methodological approaches to study darker or toxic leadership. Several antecedents and maintaining factors to toxic leadership were identified, such as individual leader characteristics, a performance-oriented culture, status/power structures, and a lack of reporting processes or consequences within organizations. The empirical literature provided initial support for the negative consequences of toxic leadership on athletes' mental health, injuries, and motivation to remain in high-performance sports. Few studies have investigated the consequences of toxic leadership on sports organizations, staff or coaches. We conclude that research on toxic leadership in high-performance sports is in its early stages, with an underdeveloped understanding of how problematic leadership can be detected, prevented, and addressed to minimize its impact in sports. Researchers, governing bodies, and sports organizations must intensify their efforts to comprehend the emergence and persistence of toxic leadership within high-performance sports environments.
