The purpose of the current study was to investigate the structural relationship between the servicescape, the emotional experience, space flow, satisfaction, and consumer loyalty in the context of sport fitness centers. Furthermore, the present study aimed to examine the moderating role of knowledge acquisition motivation in the effect of the servicescape on the emotional experience and space flow. For these research purposes, a survey study targeting 400 consumers of sport fitness centers was conducted via online and offline survey platforms in South Korea. After deleting 16 incomplete cases, 384 cases were included in the final data analysis. The results of latent moderated equations modeling (LMS) showed that the servicescape directly enhances the emotional experience and space flow. Also, it indirectly affects consumer loyalty via the emotional experience, space flow, and consumer satisfaction. Meanwhile, knowledge acquisition motivation was found to moderate the effect of the servicescape on space flow. The present study has several theoretical implications. First, the current study illuminates the process mechanism of the effect of the servicescape in sport fitness centers on consumer loyalty. Second, the present study empirically shows different patterns of consumer experiences and decision-making depending on consumption motivation. Based on the results, sport fitness center managers should not only pay more attention to the convenience of their servicescape but they should also design service environments maximizing consumers′ emotional experiences. Additionally, the results imply that assigning exercise beginners to an attractive physical environment is an effective strategy, because they are more likely to evaluate their experiences based on the perceived servicescape.
