Creativity in sport is increasingly recognized as a developmental resource to be nurtured in all participants. Yet existing literature on how coaches nurture creativity has largely centred on task-based drills and prescriptive instruction. This chapter shows how transformational leadership serves as a supplement to these task-based approaches to foster creativity. Drawing on Amabile’s Componential Theory of Creativity, creativity arises from the interaction of four key elements: sport-specific skills, flexible thinking, task motivation, and a supportive social environment. These elements are linked to the four I’s of transformational leadership (idealized influence, inspirational motivation, intellectual stimulation, individualized consideration) to show how everyday leadership behaviours create conditions that help athletes think and act in new ways. Building on research in transformational leadership and creativity, the chapter presents ten creativity-nurturing principles for coaches that translate theory into daily coaching practice. Each principle includes a brief description and a concrete example. Together, the ten principles form a practical approach that coaches can use in daily training to embrace risk-taking, idea-sharing, and fresh solutions. The chapter closes with applied notes on adapting the principles for different athletes and sport settings and outlines directions for future research, including exploring barriers and enablers to implementation.
