Environmental pollution has become a significant issue, and environmental protection within the realm of sports has garnered increasing attention from various sectors of the academic community. This study takes the public’s intention to purchase sports stadiums as the research object, introduces two mediating variables of green value perception and sense of accomplishment, builds a hypothetical model from the perspective of motivation protection theory, and explores the influence of perceived functional risk of green sports stadiums on consumption intention through SEM analysis based on the samples of the recovered questionnaires (N = 1073). The results are as follows: first, there is a negative influence between perceived functional risk and green sports stadium consumption intention, and the lower the perceived functional risk of green sports stadiums, the more consumers can promote their choice of green sports stadiums when they consume in stadiums; second, green value perception plays a mediating role in the relationship between perceived functional risk and green sports stadium services consumption intention; third, a sense of accomplishment plays a mediating role in the relationship between perceived functional risk and willingness to consume green sports stadium; fourth, green value perception and a sense of accomplishment play a chain mediating role between perceived functional risk and willingness to consume in the context of green sports stadiums. This study aims to contribute to the popularization and development of green sports stadiums in China and to provide green sports stadium builders and managers with more targeted and effective marketing strategies.

The Olympic Games are a sporting event and a catalyst for urban development in their host city. In this study, we utilized remote sensing and GIS techniques to examine the impact of the Olympic infrastructure on the surface temperature of urban areas. Using Landsat Series Collection 2 Tier 1 Level 2 data and cloud computing provided by Google Earth Engine (GEE), this study examines the effects of various forms of Olympic Games facility urban planning in different historical moments and location typologies, as follows: monocentric, polycentric, peripheric and clustered Olympic ring. The GEE code applies to the Olympic Games that occurred from Paris 2024 to Montreal 1976. However, this paper focuses specifically on the representative cases of Paris 2024, Tokyo 2020, Rio 2016, Beijing 2008, Sydney 2000, Barcelona 1992, Seoul 1988, and Montreal 1976. The study is not only concerned with obtaining absolute land surface temperatures (LST), but rather the relative influence of mega-event infrastructures on mitigating or increasing the urban heat. As such, the locally normalized land surface temperature (NLST) was utilized for this purpose. In some cities (Paris, Tokyo, Beijing, and Barcelona), it has been determined that Olympic planning has resulted in the development of green spaces, creating “green spots” that contribute to lower-than-average temperatures. However, it should be noted that there is a significant variation in temperature within intensely built-up areas, such as Olympic villages and the surrounding areas of the Olympic stadium, which can become “hotspots.” Therefore, it is important to acknowledge that different planning typologies of Olympic infrastructure can have varying impacts on city heat islands, with the polycentric and clustered Olympic ring typologies displaying a mitigating effect. This research contributes to a cloud computing method that can be updated for future Olympic Games or adapted for other mega-events and utilizes a widely available remote sensing data source to study a specific urban planning context.

The green transformation of sports stadiums has now become an inevitable trend for the sustainable development of sports. This study synthesized consumer behavior research and green consumption research, based on the CAC model, to explore the role of cognitive and affective interactions on the promotion of the intention behind green sports stadium consumption, discussing the role of environmental cognition at the cognitive level and subdividing its connotations into the three categories of a sense of environmental responsibility, environmental protection awareness, and green self-efficacy, introducing at the same time a natural connection into the field of green sports consumption, based on which the green perceived value and green trust fusion are jointly used as affective factor variables. The data from 463 questionnaires were used to construct a structural equation model for empirical analysis, and the following results were shown: First, environmental cognition, environmental responsibility, environmental awareness, and green self-efficacy have a positive effect on green stadium consumption; second, green building perceived value and trust play a mediating role in the relationship between environmental cognition and green stadium consumption intention; third, nature connection and green building perceived value and trust play a positive role in the relationship between environmental cognition and green stadium consumption intention. The purpose of this study was to explore the interaction between cognition and emotion on the the intention behind the consumption of green stadiums from the psychological level of consumers, so as to provide a reference for improving consumers’ green sports consumption and accelerating the development of the green sports industry.

This paper examined the factors influencing Chinese college students’ psychological perceptions of green retrofitting of college sports stadiums. It focused on the roles of green skepticism, future rational cognition, and future perceptual cognition. A total of 551 college students from five universities in Xi’an were tested. The results indicated that college students’ green skepticism, future rational cognition, future perceptual cognition, and psychological perceptions of green retrofitting of college sports stadiums were at a moderate level and that green skepticism had a significant and negative influence on college students’ psychological perceptions of green retrofitting of college sports stadiums. Green skepticism was a significant negative predictor of environmental values ($\beta$ = −0.183, p < 0.001), natural empathy ($\beta$ = −0.164, p < 0.001), and moral elevation ($\beta$ = −0.187, p < 0.001). In addition, future rational cognition and future perceptual cognition served as parallel mediators in the college students’ psychological perceptions of green retrofitting of stadiums. It is notable that the mediating effect of future rational cognition was greater than that of future perceptual cognition. The findings indicate that resolving green skepticism and enhancing transparency and trust are crucial for enhancing college students’ psychological perceptions and the behavioral benefits of green retrofitting of college sports stadiums. Furthermore, the facilitating effect of future rational cognition and future perceptual cognition assists college students in making more rational and ethical decisions and in garnering broad support for environmental actions.

White light-emitting diodes (WLEDs) with a high television lighting consistency index (TLCI) are becoming popular in stadium, studio, and stage lighting, but they are hard to empirically manufacture because they exploit the response of a camera rather than that of the human eye. In this study, blue chips with green and red phosphors were used to build high-TLCI WLEDs, and a spectral prediction model for WLEDs used for calculating the TLCI was established. The model considers the reabsorption and re-emission of phosphors and spectral shift. To validate the model, WLEDs with a TLCI greater than 90, from 3000 K to 7000 K, were predicted and packaged. The maximum difference in the TLCI between the measured and predicted model values is approximately 1.93%. The spectral prediction model proposed in this study is expected to provide a helpful guideline for building high-TLCI WLEDs. Full article

White mustard plant (Sinapis alba L.) is an easy-to-grow species with low soil requirements and is often sown as a catch crop in Northern Europe to reduce nitrate leaching, especially during the winter. There are studies showing the high nutritional value of mustard seeds, which have a wide application, mainly in food production. Still little is known about the young shoots or plants of different cultivars of white mustard, although in Asian countries, eating them raw is quite common. The aim of the research was to determine the proximate composition, antioxidant activity and polyphenolic compound content in young green plants of the Polish cultivars of white mustard: Borowska (traditional, with a high content of erucic acid and glucosinolates), Bamberka (non-erucic with glucosinolates) and Warta (non-erucic with low glucosinolates content; double-improved). Young plants were harvested in three terms. The first harvest took place at the plover stadium and the next ones at 7-day intervals (31, 38 and 45 day after sowing). In freeze-dried plant material, proximate composition and antioxidant activity with the ABTS and FRAP methods, as well as phenolic compound content, were measured. The highest concentration of protein was measured in cultivars Warta and Borowska after 31 and 38 days of sowing. Harvest time and cultivar affected antioxidant activity and total polyphenol content in young mustard plants. Thirty-eight days after sowing, the examined cultivars of the young plants of mustard had the highest antioxidant activity and total polyphenolic compound content. Green young mustard plants have strong antioxidant properties at the basic level, they are classified as functional foods and are similar to other edible leafy plants such as celery, spinach and Brussels sprouts.

Large stadiums are highly visible assets for large-scale ‘mega-events’, inspiring built environment professionals to innovate in structure and aesthetics. In recent years environmental performance—or environmental sustainability—has been increasing in focus, with events such as the Olympics calling for ‘green games’ and countries committing to reducing built environment carbon emissions. This paper presents a systematic literature review of large stadiums’ environmental sustainability discourse over the last five years related to design and construction. Using the PRISMA methodology, 18 relevant conceptual and empirical research papers were distilled from 159 extracted papers. Energy consumption and material composition were the most discussed topics. Emergent technologies and processes were also extensively discussed regarding significant embodied energy and indoor air-quality improvements, and greenhouse gas emissions reductions. There was a lack of best practices, or whole life cycle considerations, and minimal demonstration of other attributes of environmental sustainability. This paper provides a baseline to assess progress on environmental sustainability for the built environment sector. A practical definition is presented for Environmentally Sustainable Stadiums (ESS) and a checklist is provided to support leading practices in design and construction. This paper is relevant for built environment professionals and asset owners and managers considering new-build and refurbishments. Full article

The beneficial effects of green and blue areas on human wellbeing are significant. Physical activity is a crucial factor for the promotion of good human health and wellbeing, and running constitutes one of the most popular forms of outdoor physical activity. This study examines the effect of six urban “route landscapes” with different landscape characters used for outdoor running on the heart rates and speeds of 30 people wearing a smartwatch while running. These routes included: (1) a running track in a stadium; (2) a road without street trees; (3) a road with street trees; (4) an urban park without sea view; (5) an urban park with sea view; and (6) a road by the sea. Additionally, a questionnaire survey was conducted to determine participants’ perceptions and preferred “route landscape” for running. In the study, higher heart rates were recorded on routes without trees, including the stadium. The lowest heart rate was recorded in the park by the sea, followed by the road by the sea, which were at the lowest altitudes amongst the routes studied. Additionally, the highest mean speed of participants was recorded during the run on the road by the sea. The results also showed that irrespectively of the routes, increases in altitude and gradient caused an increase in the heart rates. In the survey, the majority of respondents stated that they would have felt calm and joy during a run either in a park or in a park by the sea. With rising sea levels dictating not to build, carbon capture being necessary in parks, and trees by roads reducing the heat island effect, this study reveals the best “route landscapes” for runners’ health and global warming.

Within the framework of the increasing importance of sports in the last few decades, researchers are focusing more and more on the role of sports facilities in the regeneration of urban areas. The existing studies, however, mainly concentrate on the effects of the investments on the built-up areas, and less attention is paid to the analysis of the relationship between these facilities and the green areas. The primary objective of our—in this context pioneer—research is to analyse the role of the new stadium in the regeneration of one of the most important green areas in Debrecen (Hungary), in Central Europe. We explore the historical influences, the need to foster development and the most significant effects of the investment. Finally, we point out the relationship between the theoretical approaches and our case study in Debrecen. Full article

Taiwan’s cities exhibit high levels of urbanization, which has resulted in limited recreation space in urban areas. In response, government policies have been enacted to promote the large-scale greening of rivers in urban areas and the establishment of aquatic recreation areas that do not interfere with water flow areas, pavilions for recreation purposes, indoor stadiums, and biking lanes alongside riverbanks to provide citizens with recreation space. An expert team was convened to investigate 50 riverside recreation sites, and the Comfortable Water Environment Rest Assessment Form was devised. The investigation results revealed three factors that contribute to the value of riverside recreation sites; the three factors had a total explanatory power of 70.17%. The factors, namely exercising and leisure, overall design plan and entrance image, and environmental maintenance and service, had an explanatory power of 25.52%, 23.32%, and 21.32%, respectively. Finally, this study provides guidance for constructing service systems for riverside recreation sites by referencing practical cases. This study suggests that future designs focus on the characteristics of visitors as the main consideration when investing resources in recreation sites. In addition, more exercise and recreation equipment and facilities should be provided at recreation sites located within highly populated areas. For recreation sites that feature beautiful scenery, greater degrees of overall design planning and entrance image qualities can be integrated into the recreation sites, and environmental teaching materials can be incorporated into the environment. Furthermore, this study suggests that residents who live near recreation sites form and operate volunteer groups to contribute to environmental maintenance and the relevant services; this would greatly enhance the overall experience of comfort of visitors to the recreation sites. Finally, this study provides guidance for low-intensity construction in high riverbank areas. Full article

After the 2002 FIFA World Cup in South Korea and Japan, the local governments of South Korea were left in charge of several large-scale soccer stadiums. Although these governments have made significant efforts toward creating profits from the stadiums, it is proving to be too difficult for several administrations to cover their full operational, maintenance, and conservation costs. In order to overcome this problem, one of the governments, Seogwipo City, which owns Jeju World Cup Stadium (JWCS), is attempting to provide an independent renewable electricity generation system for the operation of the stadium. The current study therefore examines potential configurations of an independent renewable electricity generation system for JWCS, using HOMER software. The simulation results yield three optimal system configurations with a renewable fraction of 1.00 and relatively low values for the cost of energy ($0.405, $0.546, and $0.692 per kWh). Through the examination of these three possible optimal configurations, the implications and limitations of the current study are presented. Full article
