This essay, written as part of an invited address for the National Academy of Kinesiology’s 92nd annual meeting, with the overarching theme being “Honoring the Past, Celebrating the Present, Embracing the Future,” provides an assessment of the evolution of sport and exercise psychology, or what I refer to as the psychology of physical activity. Specifically, I examine the role that psychology of physical activity has played since the academy was established, with particular attention to the contributions of academy fellows. I then provide my reflections on the current status and critical issues for the psychology of physical activity. Finally, I offer some thoughts on future directions for the subdiscipline in the broader field of kinesiology and some thoughts on how the academy could advance the academic discipline of kinesiology.
