Effect of perceived crowding on risk perception in leisure sports based on Edward T Hall’s concept of ‘proxemics’

This study investigates the social distancing measures necessary for participants to safely engage in leisure sports activities and comply with social distancing requirements during epidemics. Based on crowding and risk perception in public spaces in the context of an epidemic, this investigation was conducted in terms of distance in Edward T. Hall’s concept of ‘proxemics’. The participants were males aged 20–65 years who had used spaces for leisure sports in South Korea during COVID-19. An online survey was conducted from 20 September 2021 to 20 October 2021, and data from 391 participants were used for the �nal analysis. Measures of perceived crowding, risk perception, and Hall’s proxemics were used as tools after they had been modi�ed and validated. The results show that perceived crowding according to space for leisure sports activities during COVID-19 affected individual risk perception in indoor leisure sports and social risk perception in outdoor leisure activities. Perceived crowding according to proxemics in�uenced (1) personal, social, and public distances in individual risk perception and (2) public and social distances in social risk perception. Therefore, it is necessary to re-examine the scope of social distancing in developing risk perception and reducing the perceived crowding of participants in leisure sports to prevent the spread of infectious diseases such as COVID-19. Individuals must make an effort to maintain a minimum distance from one another, the public must be educated via the media, and warnings must be disseminated to reduce crowding and prevent infection spread.


Introduction
The COVID-19 pandemic prompted various national governments, including South Korea's, to implement comprehensive social distancing measures, which signi cantly affected people's daily lives and leisure activities (Carter et al. 2020).Globally, leisure sports spaces, which are intricately connected with other environments, experienced profound changes due to unique social distancing policies, resulting in a 41% reduction in physical activities (Wilke et al. 2021).Paradoxically, while leisure sports offer stress relief and enhance overall well-being, these spaces pose a high risk for COVID-19 transmission, which leads to social challenges such as economic downturns and community disintegration.Consequently, individuals have transitioned from indoor workouts to outdoor activities, seeking secluded spaces to engage in leisure sports (Cheng et al. 2020;Patrick et al. 2020; Shim 2020; United Nations 2020; Vazirani and Bhattacharjee 2022).However, individuals are vulnerable to infection in popular spots like sports facilities and community centres and are therefore advised to avoid crowded environments, which presents a conundrum.
The evolving perception of well-being has transformed personal spaces into organised leisure sports areas, re ecting society's changing norms.Despite concerns, physical activities have proven bene cial for individuals' physical and mental health during the pandemic (Matias et al. 2020).However, individuals tend to avoid indoor sports spaces owing to high population density and potential threats of droplet-borne infection (Jang 2020; Noh et al. 2020).While outdoor activities are perceived as safer, recent mass COVID-19 outbreaks at outdoor gatherings highlighted the need to address overcrowding, even in open spaces.While social distancing guidelines vary globally, they necessitate meticulous planning for leisure sports, both indoors and outdoors.Striking a balance between physical activities and safety requires adherence to speci c distance recommendations, often complicated by differing views on safe distances and mask usage.
Concerns about aerosol transmission are prevalent in indoor environments, especially when occupants remain seated for extended periods, emphasising the need for social interactions to be brief, regardless of social distancing norms.Evaluating adherence to existing guidelines in various leisure activities is essential to gauge their impact on crowding and infectious disease risk perception.
This study, grounded in Edward T. Hall's concept of 'proxemics', explores the perceived crowding and risk perception of individuals within particular spaces.It proposes measures for social distancing and infectious disease prevention tailored for leisure sports participants, emphasising the necessity of reevaluating social distance parameters.The research focuses exclusively on male participants aged 20-65 in South Korea, given the pandemic's differential impact on gender-speci c immune responses (Bwire 2020;Scully et al. 1977).The methodology included convenience sampling, utilising online surveys to gather data from 391 participants, and meticulous analyses after excluding redundant or incomplete responses (nine participants).This study examines the impact of the COVID-19 pandemic on perceived crowding and risk perception in diverse indoor and outdoor leisure sports settings.
Regarding study rigour, speci c focus was put on the male population for scienti c reasons related to COVID-19.Previous studies have indicated that men are more vulnerable to COVID-19 than women due to differences in immune responses (Bwire 2020).This research accordingly concentrated on males to explore the speci c challenges and perceptions they faced during the pandemic.
The importance of broadening the study's scope in future research endeavours is recognised.Further studies that will include diverse gender and demographic groups, allowing for a more comprehensive and representative analysis of the topic, are therefore planned.This approach will enhance the robustness of this study's ndings and allow for a more nuanced understanding of the effects of the COVID-19 pandemic on leisure sports activities across various populations.

Setting: Social distancing guidelines in Korea
During the research period of 30 September-20 October 2021, which included the major Korean holiday 'Chuseok', strict social distancing measures were enforced in response to the high COVID-19 transmission risk.Distinct differences in these measures were observed between the metropolitan area (Seoul) and non-metropolitan regions.Until 6 p.m., gatherings were limited to groups of four or fewer for individuals who had been fully vaccinated.After 6 p.m., gatherings were further restricted to a maximum of two individuals.Restaurants, cafes, and indoor sports facilities were allowed to operate until 10 p.m.; the latter were also required to register all visitors and record their entry and departure times.The Korea Disease Control and Prevention Agency (KCDC) implemented further protocols for indoor sports facilities, including limited occupant capacities (one person per 8 m 2 of space; one person per 6 m 2 for group exercise (GX) classes), partitions around exercise equipment, mandatory frequent ventilation and open windows, regular disinfection of equipment, provision of hand sanitiser, and maintenance of cleaning logs.Patrons had to undergo body temperature and symptom checks upon entry, were prohibited from consuming food or showering (except before swimming), and were limited to 2-hour visits.Treadmill users could not exceed speeds of 6 km/hr.Mask-wearing was required for everyone, patrons had to remain separated by a safe distance when using equipment, and direct contact sports and activities were prohibited (Kwon 2021).

Participants
All the participants in this study were males aged 20-65 who used spaces for leisure sports in South Korea during COVID-19.According to Scully et al. (1977), biological sex impacts immune responses and, therefore, we can assume it affects COVID-19 outcomes.Using convenience sampling, 400 participants were contacted through an online survey.A self-report questionnaire was distributed among the leisure sports participants.Finally, an analysis was conducted with 391 participants (nine responses were excluded as they contained unreliable data due to redundancy, or non-responses).Participants' characteristics are shown in Table 1.
According to Comrey and Lee (2013), sample sizes for each grade have been classi ed as 100 = poor; 200 = moderate; 300 = good; and 500 = very good.Our sample consisted of 391 participants and was, therefore, considered adequate.

Perceived crowding
For participants' perceived crowding of leisure sports, items of perceived crowding developed by Heberlein and Vaske (1977) and user density expectation by Graefe and Fedler (1986) and Hall and McArthur (1993) were used.The latter were modi ed and supplemented and then used after construct validation by experts (two professors of sociology of sport and leisure studies, and three doctors of leisure studies).Four items were rated on a 5-point Likert scale: 'Did you expect crowdedness to keep you from having fun before visiting the space for leisure sports activities?' 'Did you expect crowdedness to restrict activities before visiting the space for leisure sports activities?' 'Did crowdedness in the space for leisure sports activities keep you from having fun?' 'How did crowdedness in the space for leisure sports activities affect your activities?'

Risk perception
Risk perception is a concept involving individuals' cognitive processes that affect their behaviour and constant participation in relevant activities (Yoon et al. 2007).It is a subjective concept that varies among individuals and has a signi cant impact on individual decisionmaking (Gronhaug and Stone 1995).This concept must be borne in mind when considering the behaviours of participants in sports activities.Risk perception comprises subjective and objective aspects (McComas 2006); experts perceive risks based on objective data or facts, whereas the general public make judgments based on the severity of risk outcomes (Jacobs and Worthley, 1999; Kellens et al.

2011). Risk perception is generally formed by various factors and based on individual experiences and interactions with others (Slovic 2000)
. In particular, risk is perceived through media in many cases, indicating that media usage is closely related to risk perception.This observation has been corroborated by studies of infectious diseases, such as 'Middle East Respiratory Syndrome (MERS) before COVID-19' (Hong and Jun 2020).This study consequently divided risk perception into individual and media or social risk perceptions, based on measurement items used in Kim's (2020) study of novel swine u.
For risk factors, the items used were adopted from a survey developed by Knowles et al. (1973), and factors of risk perception were adopted from those used by Park (2016) and in adventure sports by Kim et al. (2019).They were employed after construct validation by a group of experts comprising two professors of the sociology of sports and leisure studies and three doctors of leisure studies.Eight survey items were rated on a 5-point Likert scale: four items on individual risk perception and four items on social risk perception.To verify that the data were normally distributed and suitable for factor analysis, this study used the Bartlett and Kaiser-Meyer-Olkin (KMO) tests; the latter gave a result of .792,indicating sampling adequacy.The total cumulative variance explained was 72.186%.Bartlett's test of sphericity was signi cant (χ 2 = 1884.735,p < .001).See Table 2 for the factor analysis.).Therefore, this study classi ed the distance required for leisure sports activities based on the idea of distance in proxemics.
The following speci c survey items were used: 1) leisure sports activities that require intimate distance (0.45 m), including jiu-jitsu, personal training, and swimming lessons; 2) leisure sports activities that require personal distance (1.2 m), such as yoga, Pilates, and squash; 3) leisure sports activities that require social distances (2 m−4 m) between individuals on both sides, for example golf, cycling, and hiking; and 4) leisure sports activities that require a public distance (7.5 m) to keep a signi cant distance from other people, such as jogging, at-home workouts, and personal exercises.

Data analysis
The collected data were analysed through coding and data cleaning followed by statistical analysis using SPSS (Ver 26.0).The data analysis method was as follows: First, descriptive and frequency analyses were conducted to identify participants' individual characteristics.Exploratory factor analysis was performed to validate the items of perceived crowding in the space for leisure activities and those of risk perception.Cronbach's α coe cients were calculated to verify the internal consistency among items and test the reliability.Correlation analysis and regression analysis were conducted to analyse the impact of perceived crowding on risk perception.All items were tested at the statistical signi cance level of α = .05.
Chung-Ang University's Research Ethics Committee reviewed and approved the protocol of this study (approval number: 1041078-202103-HRSB-090-01).The information collected and the procedure followed adhered to the Declaration of Helsinki, and the policies concerning human participants stipulated by the authors' institution, were complied with.Written informed consent was obtained from the participants before the study.The participants were informed of their right to withdraw at any time without incurring any penalty and were given the chance to ask questions for clari cation regarding the study.

Correlation analysis of perceived crowding and risk perception
Table 3 presents the results of the correlation analysis among sub-variables of perceived crowding and risk perception.The results show that the correlation between perceived crowding and sub-factors of risk perception, such as individual and social risk perception, was signi cant (p < .05).A simple regression analysis (see Table 4) was conducted to examine the correlation between perceived crowding and risk perception depending on space for leisure sports activities.Table 4 presents the regression analysis that determined the effect of perceived crowding on risk perception.These results reveal that the regression for individual risk perception due to perceived crowding was signi cant (F = 26.340,p < .001)and explained 6.1% of response variation.The regression for social risk perception was also signi cant (F = 18.218, p < .001)and explained 4.2% of response variation.Speci cally, perceived crowding affected both individual risk perception (β = .252)and social risk perception (β = .212).The tolerance limit was greater than .10,and the variance in ation factor (VIF) was less than 10, thus indicating that collinearity was not a problem.As indicated in Table 5, the regression for individual risk perception predicted in indoor spaces was signi cant (F = 8.713, p < .001)among spaces for leisure sports activities, and explained 6.8% of response variation, but was not signi cant (F = 2.275, p > .05)for social risk perception predicted in indoor spaces.The regression for risk perception predicted in outdoor spaces was signi cant (F = 17.019, p < .001)and explained 5.4% of response variation.The regression for social risk perception was signi cant (F = 18.116, p < .001),thereby indicating a signi cant effect of perceived crowding.The tolerance value was greater than .10,and VIF was less than 10, indicating that collinearity was not a problem.As shown in Table 6, among spaces for leisure sports activities, the regression for individual risk perception-predicted according to distance in Hall's proxemics was signi cant (F = 10.586,p < .001)for personal distance (within 1.5 m), and it explained 9.5% of the response variance.The regressions were also signi cant for social distance (within 3.5 m) (F = 7.712, p < .001;R 2 = .038)and for public distance (more than 7.5 m) (F = 8.472, p < .001;R 2 = .063).The regression for social risk perception also predicted according to distance in proxemics was signi cant for public distance (more than 7.5 m) (F = 10.065,p < .001;R 2 = .075)and for social distance (within 3.5 m( (F = 6.102, p < .05;R 2 = .029).The tolerance limit was higher than .10,and VIF was less than 10; thus, collinearity was not a problem.

Discussion
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 di culties, 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-thetop 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 a eld, the social atmosphere also affects leisure sports activities, which indicates that the current social distancing measures did not su ciently reduce perceived crowding and risk perception in Second, perceived crowding in uenced 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 nding 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 ndings 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 speci c 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 m 2 -15 m 2 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 signi cant 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.

Conclusions
This The major conclusions of this study are as follows.People tended to perceive severe crowding while participating in leisure sports activities owing to COVID-19; many also had a high-risk perception of infection.To resolve this issue, it is necessary to nd a way to provide people with personal space for leisure sports and help them feel mentally secure through online and non-face-to-face leisure sports that can increase social interactions.
Second, depending on indoor or outdoor spaces for leisure activities, it was found that individual risk perception was high in respect of indoor spaces, while social risk perception was high for outdoor spaces.Therefore, the capacity of indoor spaces must be limited by reducing density and allowing participants to participate in leisure sports in a secluded space, and preventive actions such as regular ventilation and sterilisation should be increased to reduce perceived crowding and risk perception of infection among participants.
Subsequently, by subdividing and analysing distance among participants in leisure sports activities based on proxemics, it transpired that individual risk perception in uenced participants' high-risk perception of personal distance, while social risk perception affected their high-risk perception of public distance.During indoor sports activities, perceived crowding and risk perception were high among participants although the capacity of indoor spaces was limited, with su cient distance between individuals compared to outdoor spaces.Additionally, even when public distances were maintained with su cient distancing among many people, it is not su cient for people to perceive safety when crowding and risk are involved.This indicates that participants believed they were not free from exposure to infectious diseases during sports activities when others were in close proximity to them.
It is therefore necessary to re-examine the scope of social distance in perceiving risk perception and to reduce the crowding perceived by participants in leisure sports activities.Individuals should endeavour to maintain a minimum distance from one another, the public must be educated about safe distancing via the media, and warning messages to prevent infection and reduce crowding must be disseminated.

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.
study examined perceived crowding in spaces for leisure sports activities of individuals under social distancing constraints imposed because of COVID-19 and their risk perception resulting from the pandemic.Various leisure sports activities were analysed by subdividing the types of distance in sports activities based on Edward T. Hall's concept of proxemics into intimate (0.45 m), personal (1.2 m), social (3.5 m), and public distances (7.5 m).
