Although rapid economic growth can produce various positive outcomes, the fast-paced society that inevitably accompanies it often results in longer working hours and higher stress levels, leading to reduced participation in sport activities among employees. To better understand this phenomenon, we aimed to explore the constraints and experiences of adult workers. We collected data from adult workers in Singapore who desired to participate in sport activities but were unable to do so due to various constraints. A total of 10 individuals were purposefully selected for interviews. This study identified four key themes: (a) factors causing the reduction of sport participation opportunities, (b) changes in sport activities and satisfaction, (c) nostalgic feelings associated with sport activities, and (d) the role of nostalgia in enhancing sport involvement. The findings of this study suggest the possibility of adapting the conceptual model of nostalgia to sport activities, as well as identifying four factors that hinder employees from engaging in sport activities.
