Abstract
As the COVID-19 crisis continues, society has re-engaged with nostalgia, especially in relation to sport and leisure. This review outlines the descriptive and analytical contours of the phenomenon and potentially useful explanatory paradigms. In doing so, this review first provides an overview of the recent studies on nostalgia in sport and leisure, especially within the context of COVID-19. Then, the review summarizes the four functions of nostalgia in sport and leisure, which include acting as a marketing tool, inducing positive behavior, serving as a buffer, and enhancing positive psychology. The review also discussed future research directions on nostalgia in sport and leisure contexts.
