Can watching the World Cup make you mentally healthier? Positive associations between involvement in physical activities and flourishing were mediated by psychological need satisfaction.

BACKGROUND: The current understanding of the relationship between physical activity involvement and flourishing, as well as the underlying psychological mechanisms, remains limited. Building upon the basic psychological need theory, this study investigates whether and how engaging in physical activities, either as a spectator (e.g., in sports events such as the World Cup) or a participant, explains individual differences in flourishing. METHODS: A total of 1201 Hong Kong-based Chinese adults (Mage = 42.90, SD = 11.40; 54% female) completed an anonymous online survey from the quarter-final to final stages of the 2022 FIFA World Cup in December 2022. RESULTS: Findings showed that spectator (World Cup) involvement and participant involvement were positively correlated. Moreover, both types of involvements were correlated with flourishing. In addition to the hypothesized positive association with relatedness satisfaction, spectator (World Cup) involvement was also demonstrated significant associations with autonomy and competence satisfaction. Path analysis indicated that associations between physical activities and flourishing were partially mediated by the satisfaction of all three basic psychological needs. CONCLUSIONS: This study is the first to apply the basic psychological need theory in the context of physical activity and supports its relevance in understanding individual differences in flourishing. Different stakeholders are encouraged to recognize the benefits of both spectator and participant involvements in physical activities, which may help them develop supportive strategies (e.g., physical activities with parents, sports events for spectators and participants, and funding for media/communities) in mental health promotion.

Exploring the factors influencing public intention for spectator sports consumption based on grounded theory.

Spectator sports consumption serves as a vital component in the development of the sports industry. However, numerous challenges exist in fostering public engagement in this domain. Therefore, in order to explore the factors that influence public participation in spectator sport consumption, this study analyzes the intention to participate in spectator sports consumption from the perspective of consumers. On this basis, Semi-structured interviews were conducted with a sample of 25 members of the public, and three levels of coding were analyzed using the qualitative research method of procedural rooting theory and establish a model on the influence of public intention to participate in spectator sports consumption, and on this basis, we reveal the influence of crucial elements. The results of the study indicate that: Firstly, personal and psychological factors are significant internal drivers, while external drivers cover product and contextual factors. Secondly, the key to filling the attitudinal and behavioral gaps is the depth of perception individually, which is of great importance in increasing public participation. Thirdly, external contextual factors impacting consumer support primarily consist of external incentives, social influences, and urban contextual variables, which also serve a moderating role in the integration model. The results suggest that guiding the public to actively participate in spectator sport consumption should be based on an understanding of individual perceptions, emotions as well as attitudes. This paper develops a model examining public motivation to engage in spectator sports locally in China, pinpoints the primary influencing factors and mechanisms, and presents novel concepts for the sustainable growth of the sports sector.

Observation of spectators' mask-wearing behavior at a national basketball tournament.

Rationale/Purpose: 1.Mass gathering events have resumed with the availability of SARS-CoV-2 vaccines. However, the pandemic is ongoing and such events potentially contribute to upsurges in COVID-19 cases. There is mounting evidence that public health mitigation strategies such as mask requirements, capacity restrictions, and physical distancing reduce transmission risk. However, evidence suggests imperfect compliance with these strategies. This study aimed to quantify spectators' masking behaviors and identify correlates of mask-wearing during a major sporting event. Design/Methodology/Approach: 2.This study used a repeated cross-sectional design, in which trained observers used a web-based application to record counts of mask-wearing. Findings: 3.Overall, 74% of spectators observed correctly wore masks. Mask-wearing behavior was associated with presumed sex, location of the spectator, game competitiveness, and whether the teams playing originated from a state with an active mask mandate. Implications: 4.Understanding the factors associated with masking behavior may help venues prepare for future events and identify innovative and targeted strategies to promote compliance with public health mitigation measures. Contribution: 5.This study makes contributions to understanding how to manage public health risks during a high-profile sporting event, specifically by identifying spectator-, game-, venue-, and state-level factors associated with mask-wearing.

Sports venue digital twin technology from a spectator virtual visiting perspective.

The purpose of this article is to adopt a customer-centric perspective the and introduce digital twin technology as a solution for mega-sport event management. This conceptual model article focuses on the potentially drastic role of digital twin technology in modern sports events, explaining in detail different aspects of its impact. The main research question is "How (and why) do sports venue digital twin emerging technologies prospectively impact the sports spectators" customer experiences?" It contributes to understanding how and why sports venue digital twins make events more customer-centred by enhancing fan experiences and engagement. Subsequently, it aims to position digital twin technology as an innovative solution for mega-sport event management across various customer experience touchpoints. By examining the intersection of digital twins and sports events from a customer-centric lens, this article will elucidate the intricacies involved in leveraging this emerging technology to transform stakeholder and fan experiences at major sporting events. Finally, we outline and explain the obstacles, challenges, opportunities, and perspectives of digital twin technology at an intersection with sports events from a customer-centric perspective. The use of digital twins potentially enables the creation of hyper-realistic virtual replicas of sports venues, providing immersive and personalized experiences for spectators. This technology allows event organizers to optimize resource allocation, streamline logistics, and improve operational efficiency.

No relevant spectator impact on home advantage in male and female professional volleyball - A longitudinal multilevel logistic model analysis over 25 years.

Home advantage (HA) regularly occurs in volleyball (Pollard et al., 2017: men: 56.62%, women: 55.26%). Research to date has investigated primarily small samples of mostly female matches and not looked into the potential impact of spectators on HA. This archival analysis uses multilevel modelling to examine HA in professional German volleyball (men & women) over 25 seasons in all regular and play-off matches (N = 6,833). We analyze how spectators drive HA and whether this projects to the COVID-19 season 2020/21. When intercepts varied between teams (2-level model, ICC = 27%), the winning probability increased when playing at home (men: 57.01%, ORmen = 2.39, d = 0.48; women: 55.39%, ORwomen = 2.19, d = 0.43), while controlling for team strength, interaction with gender, and travelling distance. More spectators had a negligible effect on the men's and women's chances (|d| < 0.07). Similar trends were observed for the probability of winning sets. Contrary to other team sports (e.g., soccer), there is no HA-development over the last decades.

Exploring the effect of the Group Size and Feedback of non-player character spectators in virtual reality exergames.

Despite the widespread interest in leveraging non-player characters (NPCs) to enhance gameplay experiences, there is a gap in understanding of how NPC spectators (i.e., those virtual characters in the scene that watch users' actions) affect players. For instance, the impact of NPC spectators' presence and feedback on players' performance and experience has not been studied, especially in virtual reality (VR) exergames. This paper aims to fill this gap and reports two user studies that assess their effect on such games. Study 1 explored the impact of having NPC spectators present and their feedback available in a gesture-based VR exergame and found having NPC spectators and their feedback could improve players' game performance, experience, and exertion. Based on Study 1's results, we further explored two characteristics of the spectators-their group size (small/large) and their feedback (with/without). The results show that (1) a large spectator number is more helpful since it improves the overall game experience (higher competence, flow, immersion), increases AvgHR% (the average heart rate percentage divided by the maximum heart rate), and enhances performance (improved players' combo performance and increased gesture success rate for particular gesture); (2) spectator feedback is instrumental in improving players' performance (higher gesture success rates, more combos performed successfully, more monster's combos prevented), enhancing game experience (positive affect, competence, flow, and immersion), and reducing negative game experience, increasing exertion (AvgHR% and burned more calories). Based on the results, we derived two main design recommendations for VR exergames that could pave the way for improving gameplay performance and game experience, especially among young adults.

Perspective: Advancing spectator behavior research in youth sports through a closer examination of racial differences.

Inappropriate spectator behaviors are a recognized challenge within both amateur and youth sport settings. These behaviors occur during youth sports contests and involve several sources of interaction, and impact the experience of child athletes, coaches, parents, and referees Spectator misconduct reflects a failure to self-regulate amidst disagreement with the coaching practices, officials, and poor performance from children. Despite widespread recognition of spectator misconduct and an emphasis by the United States Department of Health and Human Services (DHHS) to improve parent behavior, limited empirical research is available to promote understanding of both contributors to these actions, more specifically, what parents are observing from others and the frequency of such behaviors. A path to enhance research in this area is a closer examination of intersectionality, especially race and its influence upon parent observations and their personal behaviors as youth sport spectators. Based on research conducted in Louisiana, this perspective piece reflects on a study that found race as a contributing factor to differences in spectating behaviors of parents. The authors unpack the nuances of these findings through a lens of both Critical Race Theory (CRT) and implicit bias and provide a platform for future study, especially in states such as Louisiana where laws and the role of police have been advanced to mitigate spectator behaviors in youth sport settings.

Defining the challenges of Li extraction with olivine host: The roles of competitor and spectator ions.

The lithium supply issue mainly lies in the inability of current mining methods to access lithium sources of dilute concentrations and complex chemistry. Electrochemical intercalation has emerged as a highly selective method for lithium extraction; however, limited source compositions have been studied, which is insufficient to predict its applicability to the wide range of unconventional water sources (UWS). This work addresses the feasibility and identifies the challenges of Li extraction by electrochemical intercalation from UWS, by answering three questions: 1) Is there enough Li in UWS? 2) How would the solution compositions affect the competition of Li+ to major ions (Na+/Mg2+/K+/Ca2+)? 3) Does the complex solution composition affect the electrode stability? Using one-dimensional olivine FePO4 as the model electrode, we show the complicated roles of major ions. Na+ acts as the competitor ion for host storage sites. The competition from Na+ grants Mg2+ and Ca2+ being only the spectator ions. However, Mg2+ and Ca2+ can significantly affect the charge transfer of Li+ and Na+, therefore affecting the Li selectivity. We point to improving the selectivity of Li+ to Na+ as the key challenge for broadening the minable UWS using the olivine host.

CO2 Activation over Nanoshaped CeO2 Decorated with Nickel for Low-Temperature Methane Dry Reforming.

Dry reforming of methane (DRM) is a promising way to convert methane and carbon dioxide into H2 and CO (syngas). CeO2 nanorods, nanocubes, and nanospheres were decorated with 1-4 wt % Ni. The materials were structurally characterized using TEM and in situ XANES/EXAFS. The CO2 activation was analyzed by DFT and temperature-programmed techniques combined with MS-DRIFTS. Synthesized CeO2 morphologies expose {111} and {100} terminating facets, varying the strength of the CO2 interaction and redox properties, which influence the CO2 activation. Temperature-programmed CO2 DRIFTS analysis revealed that under hydrogen-lean conditions mono- and bidentate carbonates are hydrogenated to formate intermediates, which decompose to H2O and CO. In excess hydrogen, methane is the preferred reaction product. The CeO2 cubes favor the formation of a polydentate carbonate species, which is an inert spectator during DRM at 500 °C. Polydentate covers a considerable fraction of ceria's surface, resulting in less-abundant surface sites for CO2 dissociation.

The Valence Band Structure of the [Ni(Salen)] Complex: An Ultraviolet, Soft X-ray and Resonant Photoemission Spectroscopy Study.

The valence band photoemission (VB PE) spectra of the [Ni(Salen)] molecular complex were measured by ultraviolet, soft X-ray and resonant photoemission (ResPE) using photons with energies ranging from 21.2 eV to 860 eV. It was found that the Ni 3d atomic orbitals' (AOs) contributions are most significant for molecular orbitals (MOs), which are responsible for the low-energy PE band at a binding energy of 3.8 eV in the VB PE spectra. In turn, the PE bands in the binding energies range of 8-16 eV are due to the photoionization of the MOs of the [Ni(Salen)] complex with dominant contributions from C 2p AOs. A detailed consideration was made for the ResPE spectra obtained using photons with absorption resonance energies in the Ni 2p3/2, N 1s, and O 1s Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectra. A strong increase in the intensity of the PE band ab was found when using photons with an energy 854.4 eV in the Ni 2p3/2 NEXAFS spectrum. This finding is due to the high probability of the participator-Auger decay of the Ni 2p3/2-13d9 excitation and confirms the relationship between the PE band ab with the Ni 3d-derived MOs.

COVID-19 and Attendance Demand for Professional Sport in Japan: A Multilevel Analysis of Repeated Cross-Sectional National Data during the Pandemic.

In the current investigation, we assess the effect of COVID-19 on intention-based spectator demand for professional sports in Japan captured by eight, monthly repeated cross-sectional national surveys from May to December 2020 (n = 20,121). We regress spectator demand on individual (e.g., gender), prefecture-wave (e.g., COVID-19 infection status), and prefecture-level factors (i.e., with or without quality professional teams). The results of multilevel logistic regression demonstrate that individual (i.e., male, younger, full-time employment, and with children status) and prefecture-level team factors (i.e., with teams) were associated with intention-based spectator demand. Nevertheless, COVID-19-related factors were found to be unrelated to spectator demand. The findings imply that sports fans are likely to return to the stadium once behavioral restrictions are lifted. The current research provided further evidence that individual factors and team quality serve as influential antecedents of spectator demand in the context of the COVID-19 epidemic.

Effects of Game Outcomes and Status Instability on Spectators' Status Consumption: The Moderating Role of Implicit Team Identification.

This study explores the interaction effects of game outcomes and status instability and the moderating role of implicit team identification on spectators' status-seeking behavior (the pursuit and preservation of social status). The current study seeks to contribute to the existing consumer behavior and spectatorship literature by examining the counterintuitive outcomes of winner-loser effects through the application of the biosocial theory of status. In an online experiment, NFL fans' retrospective spectating experiences were captured and manipulated. This experiment used a 2 (game outcome: victory vs. loss) × 2 (status instability: decisive vs. close) × 2 (iTeam ID: high vs. low) between-subjects design. The findings indicated that decisive victories and close losses positively influenced spectators' future attendance as well as their intention to purchase luxury suites and merchandise featuring images of the team mascot. Conversely, decisive losses and close victories had a negative influence. Additionally, the more spectators implicitly identified with a particular team, the more they exhibited status-seeking behavior; even close victories positively influenced the outcomes. By applying a nascent theoretical approach in the field of consumer behavior (the hormonal account), our results provide fresh insight into explaining spectators' status-seeking behavior. Also, the findings identify specific conditions in which spectators' status-seeking behavior is enhanced, thus suggesting ways for managers to strategically allocate their resources.

Effects of Game Situation-Dependent Emotions on Sport Spectators' Food Craving.

This study sought to challenge prevalent accounts of emotional eating by exploring the effects of situation-dependent emotions on consumers' food craving. Four specific game situations in the context of spectator sports, each corresponding to the four types of emotional coping (outcome-desire conflict, avoidance, fulfillment, and pursuit), were identified as follows: decisive victories, decisive losses, close victories, and close losses. By employing laboratory-based virtual reality spectatorship, Study 1 tested the causal effects of happiness (fulfillment), anger (conflict), sadness (conflict), fear (avoidance), and hope (pursuit) on food craving. Study 2 further designed fans' previous association between emotions and eating as a moderating mechanism in the context of online sport viewership. The results of the two experiments supported the three theoretical principles of eating behavior, including the "food as fuel" principle of anger, the hedonic eating principle of happiness, and the self-regulation principle of hope. However, the results rejected the escape awareness principle of sadness and fear. The study concludes with a discussion of context-dependent emotional positioning and intervention strategies for marketers and policy makers.

An Intervention to Address Youth Sport Parent Spectator Behaviors in Louisiana: Lessons for Future Research and Social Work Practice.

Parent spectator behaviors present significant challenges within the youth sports environment. The role of parents in the youth sport experience is often overlooked, despite its documented importance to the family's youth sports experience. In order to better understand parental spectator behavior, a family systems approach guided an intervention study conducted within the state of Louisiana after a new law passed in 2019 to address these concerns. Using an adapted measurement version of the background anger instrument, results documented the role of education in addressing these concerns. The study prompts further examination of behaviors, in light of disparities between parent observations and their own personal behaviors. Implications for future intervention research on spectator behaviors and social work practice in the youth sport setting are highlighted.

Unusually Strong Biexciton Repulsion Detected in Quantum Confined CsPbBr3 Nanocrystals with Two and Three Pulse Femtosecond Spectroscopy.

Transient absorption measurements were conducted on pristine and monoexciton saturated CsPbBr3 nanocrystals varying in size within the regime of a strong quantum confinement. Once the difference spectra were translated to absolute transient changes in absorption cross section, a single exciton is shown to completely bleach the band edge absorption peak and induce a new absorption roughly two times weaker ∼100 meV to the blue. Difference spectra obtained during Auger recombination of biexciton demonstrate that the addition of a second exciton, rather than double the effect of a first, bleaches the blue-induced absorption band without producing a net stimulated emission at the band edge. Accompanied by high time resolution transient absorption spectra pumping at the lowest exciton band, these results identify the blue-induced absorption as the second transition to 1Se1Sh which is shifted in energy due to unusually strong and promptly rising biexciton repulsion. Possible mechanisms giving rise to this repulsion and prospects for applying it to enhance optical gain applications of these particles are discussed.

Understanding of Förster Resonance Energy Transfer (FRET) in Ionic Materials.

Herein, an ionic material (IM) with Förster Resonance Energy Transfer (FRET) characteristics is reported for the first time. The IM is designed by pairing a Nile Blue A cation (NBA+) with an anionic near-infrared (NIR) dye, IR820-, using a facile ion exchange reaction. These two dyes absorb at different wavelength regions. In addition, NBA+ fluorescence emission spectrum overlaps with IR820- absorption spectrum, which is one requirement for the occurrence of the FRET phenomenon. Therefore, the photophysical properties of the IM were studied in detail to investigate the FRET mechanism in IM for potential dye sensitized solar cell (DSSCs) application. Detailed examination of photophysical properties of parent compounds, a mixture of the parent compounds, and the IM revealed that the IM exhibits FRET characteristics, but not the mixture of two dyes. The presence of spectator counterion in the mixture hindered the FRET mechanism while in the IM, both dyes are in close proximity as an ion pair, thus exhibiting FRET. All FRET parameters such as spectral overlap integral, Förster distance, and FRET energy confirm the FRET characteristics of the IM. This article presents a simple synthesis of a compound with FRET properties which can be further used for a variety of applications.

Spectator medicine at an international mega sports event: Rugby World Cup 2019 in Japan.

BACKGROUND: The Rugby World Cup (RWC) is one of the biggest international mega sports events in the world. This study was conducted to identify and evaluate the volume, nature, and severity of spectator medical care in the stadiums of 12 venues across Japan during RWC 2019. METHOD: This was a retrospective review of medical records from spectator medical rooms of 45 official matches of RWC 2019 between September 20 and November 2, 2019. All patients in the stadium who visited the spectator medical room and were transferred to a hospital were included. The wet bulb globe temperature (WBGT) value at the kick-off time of each match, the number of visits to the spectator medical room, and the number of transfers to a hospital were reviewed and analyzed. The patient presentation rate (PPR) was calculated per 10,000 attendees. Severity categories were defined as mild or severe. Mild cases were considered non-life threatening requiring minimal medical intervention, and severe cases required transport to a hospital. RESULT: The total number of visits to the spectator medical room was 449 with a PPR of 2.63. Most cases (91.5%) were mild in severity. The PPR was significantly higher for the matches held with a WBGT over 25 °C than for the matches under 21 °C (PPR 4.27 vs 2.04, p = 0.04). Thirty-eight cases were transferred to a hospital by ambulance; the PPR was 0.22. The most common reasons for transfer to the hospital were heat illness and fracture/dislocation, at a rate of 15.8% each. The incidence rate of cardiopulmonary arrest per 10,000 attendees was 0.0059 during RWC 2019. CONCLUSION: Preparation and provision of appropriate medical service for spectators is a key factor for mass-gathering events. During RWC 2019, the majority (91.5%) of patients who sought medical attention did so for minor complaints, which were easily assessed and managed. On the other hand, a higher WBGT situation contributes significantly to an increased PPR (< 21 versus > 25, 2.04 versus 4.27, p = 0.04). Careful medical preparation, management, and development of public education programs for higher WBGT situations will be required in the future for similar international mega sports events.

Enhancing Older Adults' Sense of Belonging and Subjective Well-Being Through Sport Game Attendance, Team Identification, and Emotional Support.

Objective: We investigate how (a) attendance at sport games and (b) identification with a sport team as fans (i.e., team identification) influence older adults' perceptions of emotional support, belonging, and subjective well-being (SWB). Method: An experimental pilot study was conducted with 50 older adults, followed by a main survey study administered to 534 older adults from various communities across the United States. Results: Pilot study results indicated that game attendance and team identification had a positive and significant influence on older adults' perceptions of emotional support from fellow team fans. These results were replicated in the main study, which also showed that older adults' perceived emotional support from fellow fans was positively associated with their sense of belonging which predicted their SWB. Discussion: The findings provide insights into how older adults may be engaged in meaningful forms of social life to help them maintain and enhance mental health.

Are adolescent sports fans more physically active than the sports indifferent? A self-reported questionnaire study.

AIMS: Physical inactivity in adolescents is a global health problem. Eighty percent of adolescents worldwide do not meet the minimum recommended physical activity. Although many adolescents define themselves as a 'sports fan', the relationships between sports spectatorship and sport participation in adolescents have not yet been investigated. Here, we determine whether there is a relationship between the levels of sports spectatorship and physical activity among adolescents. METHODS: The Physical Activity Questionnaire for Adolescents (PAQ-A), Sport Spectator Identification Scale (SSIS) and three questions regarding total screen time spent watching a sports game and other sports-related screen time on weekdays and weekends were given to high school students in two cities in Turkey (Konya and Ankara). RESULTS: After excluding 21 invalid questionnaires, a total of 1100 full and valid questionnaires were returned from the participants (578 females, 522 males). Participants were aged between 13 and 19 (median = 15) years. Female students had lower PAQ-A (median = 2.38, interquartile range (IQR) = 0.99) and SSIS scores (median = 19, IQR = 24) and less total screen time on weekends compared to male students (median PAQ-A = 2.64, IQR = 1.05; median SSIS = 29, IQR = 30) (p < .05). The physical activity level of the students was significantly lower among those at higher grades. A weak positive correlation was found between SSIS scores and PAQ-A scores (r = .28, p < .01). Multiple linear regression analysis revealed that sex, age and SSIS scores were all significant predictors of PAQ-A scores (p < .001). CONCLUSIONS: When comparing female and male adolescents, we found that females scored significantly less in mean physical activity levels, screen time on weekends and sports spectator identification. A positive correlation was observed between sports spectator identification and physical activity levels, both in males and in females. Higher sports spectator identification, being younger and being male were all significant predictors of higher levels of physical activity.

Effect of watching professional baseball at a stadium on health-related outcomes among Japanese older adults: A randomized controlled trial.

AIM: Watching sports at stadiums can have a favorable impact on health-related outcomes in older adults. We examined the effect of watching professional baseball at a ballpark on older adults' health-related outcomes. METHODS: A total fo 58 participants aged 65-85 years were randomized into a spectator group (n = 29) and waiting-list group (n = 29). During the 2-month intervention, there were 21 games. The spectator group watched games at the ballpark, and the waiting-list group maintained their daily routines. The health-related outcomes were executive and cognitive functions, health-related quality of life, depression symptoms, subjective happiness and physical activity. RESULTS: The median days watching baseball games in the spectator group was 6 days (interquartile range 4-10 days). Executive function using the reverse Stroop interference rate showed a non-significant trend of improvement in the spectator group compared with the waiting-list group (P = 0.063). The spectator group showed a significant reduction in depressive symptoms compared with the waiting-list group (P = 0.016). CONCLUSIONS: Regularly watching professional baseball at a ballpark reduced older adults' depression symptoms. Geriatr Gerontol Int 2019; 19: 717-722.
