With the growing popularity of ice sports, indoor ice sports venues are drawing an increasing number of spectators. Maintaining comfort in spectator zones presents a significant challenge for the operational scheduling of climate control systems, which integrate ventilation, heating, and dehumidification functions. To explore economic cost potential while ensuring user comfort, this study proposes a demand response-integrated optimization model for climate control systems. To enhance the model’s practicality and decision-making efficiency, a two-stage optimization method combining multi-objective optimization algorithms with the technique for order preference by similarity to an ideal solution (TOPSIS) is proposed. In terms of algorithm comparison, the performance of three typical multi-objective optimization algorithms—NSGA-II, standard MOEA/D, and Multi-Objective Brown Bear Optimization (MOBBO)—is systematically evaluated. The results show that NSGA-II demonstrates the best overall performance based on evaluation metrics including runtime, HV, and IGD. Simulations conducted in China’s cold regions show that, under comparable comfort levels, schedules incorporating dynamic tariffs are significantly more economically efficient than those that do not. They reduce operating costs by 25.3%, 24.4%, and 18.7% on typical summer, transitional, and winter days, respectively. Compared to single-objective optimization approaches that focus solely on either comfort enhancement or cost reduction, the proposed multi-objective model achieves a better balance between user comfort and economic performance. This study not only provides an efficient and sustainable solution for climate control scheduling in energy-intensive buildings such as ice sports venues but also offers a valuable methodological reference for energy management and optimization in similar settings.

This study aims to (1) analyze thermal comfort at outdoor sport events held outside of fixed venues or locations; (2) establish a method for evaluating environmental thermal comfort for large-scale, long-term outdoor activities; and (3) provide suggestions for the arrangement of shifts in routes and participants for heat warning and mitigation. Taiwan ReAnalysis Downscaling (TReAD) data, Sky View Factors (SVFs), GSV2SVF tool, and RayMan Pro were applied to analyze and evaluate thermal comfort at the 2021 Torch Relay Round the Island, Taiwan. In this study, modified Physiologically Equivalent Temperature (mPET), Wet Bulb Globe Temperature (WBGT), and Universal Thermal Climate Index (UTCI) were estimated and selected as thermal indicators for the purpose of obtaining a more comprehensive perspective. We also define and present thermal performance with a simple traffic light symbol (green: comfortable/yellow: warm/red: hot) and try to go beyond the concept of heat and visualize it in an easy-to-understand way.

Interventions have been designed to close achievement gaps in Science, Technology, Engineering, and Math (STEM) disciplines and to remedy the “leaky STEM pipeline”. However, there has been little focus on designing complementary interventions that seek to broaden the youth population who “enter the STEM pipeline”. The current work aims to broaden STEM engagement in youth by developing a STEM intervention using unrecognized forms of cultural capital. These novel, basketball-based interventions were designed to engage a naturally occurring population of youth with pre-existing interest in sports but low levels of pre-existing STEM interest, ranging from the 2nd to the 12th grades. These interventions utilized sports as a venue for informal STEM learning across three variations: a single-hour event, a one-day clinic, and a multi-day camp. Participants’ interest in pursuing a STEM career significantly increased across all three variations of the STEM intervention. Notably, these effect sizes were descriptively larger for programs of longer duration and were significantly stronger for students who reported playing basketball prior to the program. The current work introduces a novel STEM education intervention that has been shown to be repeatedly successful in utilizing students’ pre-existing interest in sports as a bridge to STEM engagement.

In recent years, China has continuously increased the construction of sports facilities, with the number and area of sports venues steadily growing. The use of more energy-efficient ventilation methods in gymnasiums has become one of the research hotspots. Taking a multi-functional gymnasium in Wuhan as an example, the gymnasium adopts a seat air supply device driven by natural wind to enhance indoor ventilation. This study uses the methods of field measurement and CFD simulation to analyze the application effect of this new type of natural ventilation device in hot summer and warm winter areas during the transition season. Through CFD simulation of the ventilation performance of the seat air supply at different opening rates, the indoor ventilation effect and thermal comfort were analyzed. The application of the seat air supply greatly improved the indoor environment and enhanced the comfort of personnel. After turning on the seat air supply, the maximum temperature difference between the indoors and outdoors increased from 1.7 °C to 3.4 °C, the natural air intake rate increased from approximately 50% to approximately 70%, the wind speed in the seat area significantly increased, the uniformity of the wind speed field in the movement area significantly increased, and the proportion of areas with low wind speed and no wind speed decreased to 9.6%. The proportion of areas with wind speeds ranging from 0.3 to 0.5 m/s increased from 8.8% to 33.0%. At 10:00 a.m., the temperature at the indoor station was relatively low. The opening of the seat air supply device reduced the PMV value of the front seats by an average of 0.39. When the indoor platform temperature reached the maximum value, the impact of equipment activation on the PMV index of the seat area was relatively small, with an average reduction of only 0.19. The research results show that the application of a natural wind-driven seat air supply in sports venues is very promising, providing a new idea for the energy-saving renovation of gymnasiums and effectively promoting the development of low-carbon undertakings.

With the development of the economy and improvements in living standards, public demand for sports activities has continued to increase. However, the supply–demand relationship of urban sports venues remains unbalanced in many cities. Existing theoretical research on the spatial allocation of sports venues predominantly focuses on macro-level functional configuration and the equitable distribution of sports resources, lacking more rigorous and quantitative evaluation frameworks for evaluating spatial allocation. This study innovatively integrates multi-source data into the assessment and sustainable optimization of sports venue allocation in urban planning, using Xi’an as a case study. By analyzing geographic information, road network topology, OpenStreetMap (OSM), population distribution, and social media Points of Interest (POI), and using analytical tools such as ArcGIS 10.8 and Stata 17, the appropriateness of resource distribution of public sports venues in Xi’an’s main urban area is evaluated from three dimensions: accessibility, equity, and spatial activity. The results reveal the appropriateness of venue distribution in urban spatial allocation, the equitable distribution of resources, and imbalances in spatial activity and resource distribution. Finally, the study proposes a series of sustainable optimization strategies, including increasing venue coverage in low-supply areas, adaptive reuse of idle industrial buildings into sports venues guided by green sustainability principles, constructing a “15-min fitness circle” spatial system, optimizing low-carbon mobility networks around venues, enhancing the compatibility of sports venues, and improving commercial operation and management capabilities. These strategies aim to optimize the distribution of public sports venues in Xi’an to improve fairness and operational efficiency in service delivery while promoting sustainable urban development.

The wind field plays an important role in the maintenance of large sport venues. Most wind field simulation research involves no quantitative analysis of the impacts of the wind environment on athletes’ safety and performance. Taking the National Sliding Centre (NSC) of the Beijing 2022 Winter Olympics as the research object, this paper conducts a wind field simulation study based on CFD, and innovatively explores the quantitative impact of building-scale wind environment characteristics on micro-athletes’ wind resistance and performance for the first time. First, an NSC model and a human body model of athletes are constructed and simplified. Grid independence verification is carried out, and the grid is divided and optimized. Second, wind environment simulation under different climatic conditions is completed, based on CFD technology. The defined wind speed dispersion indexes are calculated. The characteristics of the wind field outside the venue is quantitatively analyzed. Third, we define and calculate the main influencing parameters on athletes’ competition performance. The impacts of the wind field on micro-athletes’ performance are quantified. With a gradual increase in wind level (3.125, 3.5, 4.5, 5.5, 6.5, 7.5, 8.229), the optimized sliding route can reduce the air resistance by 0.2607 N, 0.3415 N, 0.4600 N, 0.6469 N, 0.9283 N, 1.1741 N, and 1.4535 N, which can improve the athletes’ competition results by 0.02 s, 0.03 s, 0.04 s, 0.06 s, 0.09 s, 0.11 s, and 0.14 s, respectively. This paper provides methodological support for exploring the mechanism of athlete performance from the perspective of a building-scale environment. Full article

The lack of energy-saving design in national fitness centers has affected low-cost operation and indoor comfort. Existing studies mainly focus on the impact of lighting and heat on energy consumption in sports stadiums, highlighting the need for the comprehensive planning of natural ventilation design to improve energy efficiency. This study uses the national fitness center in Qingdao as a case study, collecting building environmental information through field measurements and questionnaire surveys. Four design elements were selected: the window-to-wall ratio (WWR), proportion of operable window area (OWAR), skylight area ratio (SAR), and floor plan layout. Through the utilization of Ladybug Tools in combination with Radiance and EnergyPlus, an annual energy consumption simulation under natural ventilation conditions was conducted using an airflow network model. This study found that the WWR has a significant impact on lighting, ventilation, and energy consumption. The optimal WWR configuration for the venue was determined to be 0.37 for the north facade, 0.26 for the east, 0.53 for the south, and 0.41 for the west. Compared to no natural ventilation, cooling energy consumption was reduced by 18.02%, and fan energy consumption decreased by 11.03%. The energy-saving effect was optimal when the OWAR was approximately 30%. When the SAR reached 5%, cooling and lighting energy consumption were significantly reduced, resulting in the lowest total energy consumption. The study also compared the energy consumption differences in various floor plan layouts under the influence of natural ventilation. This research evaluates the natural ventilation efficiency of community fitness centers, avoiding the hidden energy consumption transfer typical of traditional single-objective optimization methods, and improves the energy-efficient design approach for national fitness centers.

In response to public health emergencies, the importance of resilient medical facilities—such as large exhibition centers and sports venues that can be rapidly converted into temporary emergency hospitals—has become increasingly evident. This study focuses on these potential medical resources within megacities, using Shanghai as a case study. Employing advanced analytical tools including the kernel density two-step floating catchment area method, Lorenz curves, and Gini coefficient, we systematically evaluated the spatial allocation of 36 resilient medical facilities in Shanghai. The findings indicate that Shanghai’s resilient medical facilities ensure 4.5 emergency beds per thousand residents, with large exhibition centers and sports venues demonstrating exceptional conversion capabilities far surpassing those of ordinary public venues. However, the study also uncovers significant disparities in spatial allocation: these facilities are predominantly concentrated in the city center, leading to notable deficiencies in accessibility and equity for suburban areas. The opportunity for residents to access emergency medical services decreases progressively from the city center outward, a trend consistent across various travel time scenarios. The calculated Gini coefficient underscores an extremely uneven spatial configuration of resilient medical facilities, well beyond the warning threshold, suggesting substantial service disparities between different regions during emergencies, which poses potential risks to public health. Our research provides valuable insights for megacities aiming to more effectively address future public health challenges and enhance societal resilience. Full article

Background/Objectives: The practice of physical activity contributes to obtaining adequate values of body composition and physical fitness, which is beneficial for people’s health. However, a large part of the adult population does not comply with the recommendations for physical activity, due to factors such as lack of time and nearby sports venues. Immersive virtual reality is a tool that allows individuals to immerse themselves in a simulated world and perceive visual, auditory, and tactile sensations. Its use in physical activity interventions favors exercise in situations that, due to time and space, could be limited in real life. The objective of this case report is to measure the impact on body composition and physical fitness of an exercise program executed through immersive virtual reality. Methods: The design is a case study with a quantitative approach developed through a physical activity intervention with immersive virtual reality in which body composition was evaluated considering fat and muscle components, and physical fitness considering cardiorespiratory fitness, speed-agility, and hand grip strength, through pre- and post-testing. The physical exercise program based on immersive virtual reality lasted 8 weeks. The subject of the study was a 24-year-old man, a second-year student of Pedagogy in Physical Education at a Chilean university, with no previous experience in this virtual tool. Results: The results indicate that for body composition the study subject decreased the fat component and slightly improved the musculature, while for physical fitness cardiorespiratory fitness and speed-agility improved, but manual grip strength decreased. Conclusions: It is concluded that the training developed through immersive virtual reality proves to be a tool that can promote improvements in body composition and physical fitness; it is necessary to carry out more research to validate the potential of this instrument as a means of contributing to the health of the population.

With rapid urbanization, improving school quality in compulsory education is critical for optimal educational resource allocation. This study integrates a random forest machine learning model, GIS spatial analysis, and a spatial econometric model to examine the spatiotemporal differentiation of school quality in Dalian, China, in 2016 and 2020, as well as its relationships with the construction land development cycle, population density, and housing prices. The findings reveal a core–periphery structure, with overall school quality on the rise and basic facility configuration exerting a stronger impact than teacher strength. Among internal resources, per capita sports venue area (PCSFA) and per capita teaching equipment value (PCTRE) contribute most significantly to school quality, while high-quality clusters in traditional educational hubs, university-covered areas, and transitional zones spur improvements in surrounding schools. The population density, housing prices, and the construction land development cycle all positively correlate with school quality, highlighting the need for coordinated action among urban planners, education authorities, and housing regulators to ensure that land development, housing affordability, and school facility investments advance equitable access to quality education. These results provide a novel perspective on compulsory education quality assessment and offer a valuable foundation for guiding education policies and urban development strategies. Full article

The aim of the present study is to identify obesogenic environment profiles to find the obesogenic environment pattern for Belo Horizonte City. The current research followed the ecological approach and was substantiated by data from food shops, public sports venues, crime rates (homicides and robberies) and the rate of accidents with pedestrians. Descriptive analyses and principal component analysis (PCA) were conducted in Stata software, version 14.0. Georeferencing and map plotting were carried out in Qgis software, version 2.10. All neighborhoods in Belo Horizonte City (n = 486) were included in the study. The obesogenic pattern comprised the highest mean number of shops selling ultra-processed food, crime rates, and accidents with pedestrians. The generated latent variable was divided into tertiles, and the second and third tertiles represented the most obesogenic environments. Neighborhoods accounting for the highest obesogenic profile also recorded the largest number of shops selling all food types. Furthermore, neighborhoods in the third tertile recorded the highest mean income (BRL 2352.00) (p = 0.001) and the lowest Health Vulnerability Index (HVI = 54.2; p = 0.001). These findings point towards the need for developing actions, policies and programs to improve these environments, such as tax incentives to open healthy food retailers and public sports venues to promote healthier lifestyles and to prevent diseases in the middle and long term.

Currently, sports venues are endowed with the important functions of providing sports venues and facilities to the urban public, watching sports events, publicizing the mass sports culture, etc. An in-depth study of how to enhance the attractiveness of sports venue buildings and the competitiveness of the industry to stimulate the public’s potential for sports consumption is necessary. Based on the perspective of color psychology, this study constructs a three-level structural equation model based on the nested data obtained from the questionnaire survey to explore the relationship between managers’ innovative sports venue colors, athletes’ perceived emotional value, and consumers’ sports venue satisfaction. The results show that innovative sports venue colors have a significant positive effect on consumers’ satisfaction with sports venues, and the perceived emotional value has a positive mediating role in the effect of innovative sports venue colors on consumers’ satisfaction with sports venues. This study aims to provide a basis for sports venue managers or event organizers to improve athlete satisfaction, optimize consumer experience, stimulate residents’ motivation to attend games, and strengthen the profitability of the venues.

As an important carrier of sports services and the main force participating in the “short board” project of urban development, the renovation and upgrading of old stadiums have become an important trend for the sustainable development of venues in the context of urban renewal, consumption upgrading, and national fitness. However, owing to the complexity of the transformation process, the probability of safety accidents continues to increase, posing a serious threat to national property security. In order to reasonably evaluate the safety of the stadium renovation construction process and reduce the incidence of accidents in the renovation project, this study proposed a safety evaluation model for the stadium renovation construction based on the combination weighting extension model. First, according to the 5M1E theory, 27 influencing factors were selected, a safety evaluation index system for stadium reconstruction construction was constructed, and the safety evaluation grade of the index was quantified. Second, based on the analytic hierarchy process (AHP) and improved entropy weight method, the combination weight of the index was determined, and a safety evaluation model was constructed using the matter–element extension theory. Finally, the established evaluation model was applied to the example of stadium renovation, and the construction safety level of the renovation project was obtained. The research results showed that the model has strong operability, and the evaluation results are reasonable and reliable, providing a new concept for the safety control of stadium reconstruction construction.

Repeated exposure to water treadmill (WT) exercise could elicit kinematic responses reflecting adaptation to WT exercise. The study’s aim was to compare the responses of a group of sport horses to a standardised WT exercise test (WT_SET) carried out at three time points, week 0 (n = 48), week 20 (n = 38), and week 40 (n = 29), throughout a normal training programme incorporating WT exercise. Horses were recruited from the existing client populations of two commercial water treadmill venues for the purpose of this longitudinal, observational study. Limb, back, poll, wither, and pelvic kinematics were measured during the WT_SET using videography, optical motion capture, and inertial motion sensors. Forelimb and hindlimb protraction increased (p < 0.001 for both), and forelimb and hindlimb retraction decreased (p < 0.001 for both) at week 40 compared to week 0. Caudal thoracic flexion–extension and lateral bend ranges of movement were greater at week 40 compared to week 0 (p < 0.001 and p = 0.009, respectively). Increased training speed was associated with increased craniocaudal poll movement (p = 0.021), decreased forelimb protraction (p = 0.008), and increased forelimb retraction (p = 0.021). In addition to characteristic changes in kinematics due to increasing water depth, regular WT exercise resulted in kinematic adaptation to movement in water. Factors such as the frequency of WT sessions and the type of session used with respect to depth and speed were seen to influence the nature of the adaptation. The results suggest that WT exercise sessions could be designed in accordance with specific training goals when used within a normal sport horse training programme. Full article

Background: This study investigates the relationship between Virtual Reality Exposure Therapy (VRET) and social anxiety in sport environments. Social anxiety is a mental health condition that manifests people’s intense fear of being watched and judged by others and worrying about humiliation It is important to research potential tools like VRET that could help to mitigate the impact of social anxiety as people with social anxiety often avoid attending live events due to the venue’s sensory stimuli and the social encounters they anticipate. VR simulation could allow socially anxious individuals to fully experience a sporting event simulation minus the anxiety induced by potential social encounters. VR’s therapeutic effects on social anxiety should be explored when considering several findings of VR intervention to mental health. Aim: The study aims to assess the impact of exposing socially anxious people to a virtual sporting game by measuring their levels of social anxiety, team identification, and intentions to attend a live sporting event before and after the VR exposure. Due to VR’s positive experience, social anxiety is expected to decrease. However, team identification and intentions to attend live sporting events are expected to increase because of VR’s ability to develop sport fanship. Method: Fourteen students with symptoms of social anxiety participated in the study. To create the VR simulation stimuli, the researchers used six 360° cameras to record an NCAA Division-I women’s volleyball game. Participants experienced the sporting event via VR simulation. Data were analyzed via one-group pre- and post-comparison. Results and Conclusions: Significant results were found for behavioral intentions of participants after experiencing the simulation. Social anxiety’s difference was negative 0.22, t(13) = 3.47, p < 0.01. After watching the game in VR, the respondents’ social anxiety decreased significantly. Team identification’s difference was 0.53, t(13) = −3.56, p < 0.01. Lastly, event visit intentions’ difference was 0.24, t(13) = −2.35, p < 0.05. Team identification and intentions to visit a sporting event rose significantly after viewing the game in VR. Full article
