This study subdivided leisure sports activities based on distance according to Edward T. Hall’s concept of proxemics and demonstrated the effect of proxemics on the perceived crowding and risk perception in spaces of individuals who participated in various leisure sports activities during COVID-19.
First, perceived crowding affected risk perception depending on the space for leisure sports. Therefore, it is necessary to provide ways to encourage participation in safe and stable leisure sports activities while promoting awareness of the risks of infectious diseases and reducing perceived crowding. Similar results were found for severe acute respiratory syndrome and Middle East respiratory syndrome before COVID-19. Additionally, daily life activities were disturbed and obstructed by the symptoms of COVID-19, such as breathing difficulties, fatigue, arthralgia, muscle pain, anxiety, and depression (Carter et al. 2022). Considering that people perceived physical activities outside their homes to be dangerous owing to the spread of COVID-19, methods of online leisure (Zoom dinner parties, over-the-top media services, online PC games, etc.) (Kim 2020; Park 2023) and sports activities were investigated. Here, the level of risk may vary depending on perceived crowding among individuals; further afield, the social atmosphere also affects leisure sports activities, which indicates that the current social distancing measures did not sufficiently reduce perceived crowding and risk perception in spaces for leisure sports (Mehta 2020; Ping et al. 2020; White and Van Der Boor 2020). Yang and Park’s studies demonstrate that policies such as social distancing or restrictions on excursions because of COVID-19 constrain physical activities. As such, those participating in many physical activities are affected more by COVID-19 (Woods et al. 2020; Yang and Park 2021). That is, it is necessary to reduce the fear of risk factors and crowdedness felt by people and to increase awareness of risk factors.
Second, perceived crowding influenced individual risk perception in indoor spaces for leisure sports and social risk perception in outdoor spaces. Furthermore, the proportion of participants in outdoor leisure sports activities in this study was twice than that of indoor activities. This is consistent with Kim and Kang’s (2021) report that while the proportion of indoor leisure sports activities was high, COVID-19 increased perceived crowdedness and risk perception in indoor activities; thus, people participated more in outdoor activities. Yang et al. (2019) agreed that even after implementing various preventive methods provided in spaces for leisure sports activities, activities in secluded spaces or outdoors away from compact and dense spaces among participants did not reduce perceived crowding or constraints on participants.
The World Health Organization (2020) recommended that people maintain physical distance while carrying out physical activities, suggesting that they wear masks in parks or open public spaces where people are walking or jogging. Wijngaards et al. (2022) revealed that indoor leisure sports activities increased in winter when outdoor exercising is relatively uncomfortable and participation in indoor leisure sports activities increased among vaccinated people. Their finding indicates that risk perception of infectious diseases may vary depending on vaccination status. If risk perception can be reduced by vaccination, keeping an adequate distance among participants may be more important for reducing perceived crowding. Therefore, to reduce the risk perceived by individuals due to crowding in indoor spaces for leisure sports, it is necessary to provide hand sanitisers in various parts of sports facilities as preventive measures against infectious diseases, sterilise sports equipment every hour, and ventilate the space for 10−15 minutes every hour in between classes for group exercises (WHO 2020; KCDC 2020).
These procedures must be strictly managed by displaying daily checklists that are visible to all participants. Moreover, in outdoor spaces for leisure activities, all participants must be allowed to engage in leisure sports activities because, regarding COVID-19, it is safer to engage in such activities outdoors than indoors. Furthermore, unnecessary chats, long telephone calls, and food and beverage consumption in crowded spaces should be banned.
Finally, according to proxemics, perceived crowding in spaces for leisure sports activities affects personal, social, and public distances in individual risk perception and on public and social distances in social risk perception. Many people ignored or forgot about the social distance rules at the beginning of the pandemic and maintained crowding. This result was inconsistent with the findings of previous studies that showed that crowding led to evasive action among users (Kim and Hong 1998; Manning 1999), and studies of outdoor sports activities (Andereck and Becker 1993; Ditton et al. 1983; Donnelly et al. 1986) that revealed individuals perceive higher levels of crowding when they notice higher than expected densities during sports activities. That is, participants in leisure sports activities were aware that there would be a high level of infection exposure in enclosed spaces and perceived high levels of crowding due to limited space, but they showed low-risk perception, thinking that they would not be infected during leisure sports activities regardless of how many participants there were or how close their proximities might be. Thus, it is important to develop more specific and substantial leisure policies for participants, such as creating a safe environment for individuals to engage in leisure sports activities (Kim and Lee 2020).
Ultimately, it is necessary to establish guidelines for accurate preventive actions and ensure that all participants understand the need to perform social distancing by maintaining a minimum safe distance during leisure sports activities to engage in safe and healthy leisure sports activities while perceiving a certain level of risk of infectious diseases (Morawska and Cao 2020; Setti et al. 2020). That is, participants should be allowed to maintain a minimum distance from one another during leisure sports activities where they can perceive risk and reduce crowding or maintain low congestion by keeping a 10 m2–15 m2 distance between them; it is also necessary to set a particular number of participants who can be accommodated each hour in indoor spaces with high levels of crowding.
During the period under study, participants in Korea were generally well informed about the spread of COVID-19 and measures to prevent contamination. The government and health authorities actively communicated guidelines, including the necessity of having COVID-19 vaccinations to access indoor sports facilities. Facilities also implemented rigorous protocols, such as temperature checks, verifying vaccination status, and enforcing social distancing measures. These efforts ensured that individuals entering facilities were aware of COVID-19 risks and were taking the necessary precautions to prevent its spread. Overall, participants were expected to have a good understanding of these preventive measures owing to the strict regulations and extensive public awareness campaigns.
Despite its significant results, this study has a few limitations. First, it was conducted with participants of leisure sports activities without considering those who could not continue participating in leisure sports owing to COVID-19 restrictions, as well as adolescents and older adults who could not easily participate in these activities. Second, the percentage of participants involved in outdoor leisure sports was 71.4%, but it was not determined whether these participants were engaged in indoor activities before COVID-19 and then switched to outdoor activities afterward, or if they changed because of crowdedness and risk factors in indoor spaces. Finally, this study did not reveal that the correlation between depression and perceived crowding or risk perception among participants in leisure sports activities was becoming more prominent due to frequently changing social distancing policies and tight constraints. Perceived crowding and risk may vary depending on an individual’s level of depression, and thus, different approaches must be taken to resolve it. It is therefore necessary to adopt healthy lifestyle management methods and personalised intervention programs for infection prevention based on individual lifestyles and healthcare standards.
