Analysis on the Influence of Students’ Health Quality Based on Intelligent Optimization of Sports Facilities and Equipment

Physical health promotion has always been a way for schools to pay close attention to and devote resources to their students’ development, physical fitness, and social adaptability. To promote the improvement of students’ overall physical quality, we must begin with the foundation and school physical education. This study proposes an improved K-means algorithm based on an analysis of the influencing factors of intelligent optimization of sports facilities and equipment on students’ health quality. Clustering analysis is carried out based on two groups of data classified as boys and girls, using the improved K-means algorithm. The findings reveal that the average change trend of physical fitness test items in each male cluster is generally similar, with a moderate change. The change in the average score of physical fitness test items for each cluster of girls in the group showed two distinct valleys, and the trend was complicated. This necessitates schools to invest funds to construct venues and purchase equipment in order to increase the number of sporting events.

Participation in Sports Activities before and after the Outbreak of COVID-19: Analysis of Data from the 2020 Korea National Sports Participation Survey

The present study aimed to describe the characteristics and rate of participation in sports activities, changes in sports, and the causes of these changes before and after the COVID-19 out-break in Korea using data from the 2020 Korea National Sports Participation Survey (KNSPS). Furthermore, evidence from this study could be used as basic data to maintain and promote sports activities given the current situation, in which the continued spread of infectious diseases, such as COVID-19, is likely. The KNSPS is an annual survey of subjective health and fitness, sports activities and conditions, and participation in sports activities, conducted among a sample comprising the entire Korean population. The current study analyzed data for 9000 participants, and descriptive statistical analysis was performed to calculate the frequency of each item and sample weight. The rate of regular participation in sports activities at least once a week was found to be 60.10% in 2020, representing a decrease of 6.48% from the rate observed in 2019. Among the types of sports facilities frequently used within the residential area, the most common facilities were private sports facilities (22.97%), other sports facilities (20.60%), and public sports facilities (18.97%), although the utilization rate for other sports facilities increased after the COVID-19 outbreak. After the COVID-19 outbreak, 34.12% of men and 29.72% of women responded that there had been a change in their participation in regular sports activities. Both before and after the COVID-19 outbreak, walking was the most common activity, although the participation rate increased from 29.23% in 2019 to 35.70% in 2020. The rankings and participation rates for indoor sports activities (bodybuilding, swimming, etc.) tended to decrease, while those for outdoor sports activities (climbing, cycling, etc.) tended to increase. These changes may be explained in part by the increasing concern regarding infection with increasing age, except among teenagers, and by economic factors. While participation in physical activity provides numerous health benefits, the COVID-19 pandemic has had a negative impact on regular participation in sports activities. The results of this survey suggest that government action is required to enhance participation in sports activities, even in the face of a pandemic.

The legacy of the 1936 Winter Olympics in Garmisch-Partenkirchen in the context of sports tourism

The IV Winter Olympics in Garmisch-Partenkirchen (Ga-Pa) are regarded by researchers as a test stage for the international demonstration of the German Reich’s economic power in relation to the Games of the XI Olympiad in Berlin, which were organized half a year later. Through the Games, Adolf Hitler sought to test all of his resources and means, thereby testing the country’s readiness to host another major sporting event. Despite numerous controversies related to the intense exposition of Nazi politics and anti-Semitism, the Olympic Games were remembered among the international public as a professionally organized event, among others thanks to the modern and extremely functional sports facilities of the time. The aim of this paper is to characterize the Olympic legacy of Ga- Pa, which due to its numerous remnants and nowadays well-maintained historical sports base contributes to the development of sports tourism in Germany. This account is briefl y preceded by an account of the preparation and course of the IV Winter Olympics.

Method for Forecasting Urban National Sports and Fitness Demand Based on Ant Colony Algorithm

With the continuous development of social economy, when people are pursuing economic income, they are also gradually paying attention to their own physical health. They achieve their own physical exercise through sports such as running, fitness, and mountaineering, but these sports often require a certain venue and equipment. Therefore, in view of these sports fitness demands, the ant colony algorithm is introduced to sort out the fitness activities in the context of urban residents’ supply and demand relationships, analyze the demand from both subjective and objective aspects, and explore the lack of supply of sports facilities in this paper. Analysis is conducted from cognitive and national fitness, social needs, habits, and other perspectives. It tries to guide the rational allocation and creation of resources, obtain residents’ fitness awareness and support, and provide corresponding suggestions and support for residents’ fitness activities. The simulation experimental results show that the ant colony algorithm is effective and can support the predictive analysis of the urban national fitness demand.

COVID-19 Passport as a Factor Determining the Success of National Vaccination Campaigns: Does It Work? The Case of Lithuania vs. Poland

As the ongoing COVID-19 pandemic poses a global threat, it is of utmost importance that governments should find effective means of combating vaccine hesitancy and encouraging their citizens to vaccinate. In our article, we compare the vaccination outcomes in the past months in two neighbouring post-communist EU states, Lithuania and Poland. Both introduced COVID-19 certificates, but only the former followed with gradual limitations for those who failed to get vaccinated, beginning with restricted access to restaurants, sports facilities and indoor events, and finally banning residents without a certificate from entering supermarkets or larger shops and using most services. By contrast, in Poland, the certificate remained a tool for international travel only. We show using statistical data that Lithuania’s strict policy, regardless of its social implications, led to markedly higher vaccination outcomes in all age groups than those in Poland at the time.

Exploring the Determinants of Urban Green Space Utilization Based on Microblog Check-In Data in Shanghai, China

Urban green space has significant social, ecological, cultural and economic value. This study uses social media data to examine the spatiotemporal utilization of major parks in Shanghai and explore the determinants of their recreational attraction. Methods: Based on microblog check-in data between 2012 and 2018 across 17 parks in Shanghai, we investigated the patterns at different temporal scales (weekly, seasonal and annual) and across workdays and weekends by using log-linear regression models. Results: Our findings indicate that both internal and external factors affect park utilization. In particular, the presence of sports facilities significantly contributes to higher visit frequency. Factors such as the number of subway stations nearby, scenic quality and popularity have a positive impact on check-in numbers, while negative factors affecting park use are number of roads, ticket price and average surrounding housing price. Across different temporal scales, the use patterns of visitors have obvious seasonal and monthly tendencies, and the differences of workday and weekend models lie in external factors’ impacts. Conclusions: In order to achieve the goal of better serving the visitors, renewal of urban green spaces in megacities should consider these influential factors, increase sports facilities, subway stations nearby and improve scenic quality, popularity and water quality. This study on spatiotemporal utilization of urban parks can help enhance comprehensive functions of urban parks and be helpful for urban renewal strategies.

Physical Activity and Sports Practice in Children and Adolescents at the Time of the COVID-19 Pandemic: Hypothetical Future Scenarios and Preventive Practical Applications

As a logical and direct consequence of the closure of schools and sports facilities, an expected reduction in the practice of physical activity (PA) and sports has been detected in both children and adolescents all over the world. Hence, we analysed the short-term and long-term consequences of the lack/low level of PA and sports activity in this population, which we referred to as primary and secondary risks, respectively, the latter of which have to be considered in hypothetical future scenarios.
