The Impact of COVID-19 on Sport in Twitter: A Quantitative and Qualitative Content Analysis

[EN] The spread of the SARS-CoV-2 virus has transformed many aspects of people's daily life, including sports. Social networks have been flooded on these issues. The present study aims to analyze the tweets produced relating to sports and COVID-19. From the end of January to the beginning of May 2020, over 4,000,000 tweets on this subject were downloaded through the Twitter search API. Once the duplicates, replicas, and retweets were removed, 119,253 original tweets were analyzed. A quantitative-qualitative content analysis was used to study the selected tweets. Posts dynamics regarding sport and exercise evolved according to the COVID-19 pandemic and subsequent lockdown, shifting from considering sport as a healthy bastion to an activity exposed to disease like any other. Most media professional sporting events received great attention on Twitter, while grassroots and women's sport were relegated to a residual role. The analysis of the 30 topics identified focused on the social, sporting, economic and health impact of the pandemic on the sport. Sporting cancellations, leisure time and socialization disruptions, club bankruptcies, sports training and athletes' uncertain career development were the main concerns. Although general health measures appeared in the tweets analyzed, those addressed to sports practice were relatively scarce. Finally, this study shows the importance of Twitter as a means of conveying social attitudes towards sports and COVID-19 and its potential to generate alternative responses in future stages of the pandemic.González, L.; Devis-Devis, J.; Pellicer-Chenoll, M.; Pans, M.; Pardo-Ibáñez, A.; García-Massó, X.; Peset Mancebo, MF....

The physical activity of Spanish speleologists: accomplishment of recommendations and differences by sociodemographic variables

Outdoor adventure activities are becoming more popular due to their potential health benefits, although there is little scientific information on speleology as a physical activity (PA). The purpose of this study is to expand the scientific evidence in this field in two ways: (a) describe the PA performed by speleologists, taking into account the variables of interest such as gender, age, education, speleological level, participation in ‘Alpine’ explorations and body mass index (BMI) and (b) identify how far the World Health Organization’s (WHO) PA recommendations were accomplished (i.e.,150 min of moderate-intensity aerobic PA or 75 min of vigorous-intensity aerobic). A cross-sectional study was conducted on 436 speleologists (305 men, 130 women). The participants completed an electronic survey on PA after which a descriptive analysis and cross-sectional pairwise comparisons (Mann–Whitney U and Kruskal–Wallis tests) were performed on the non-normal data. The mean metabolic equivalent (MET)-minutes/week was 4070.80 (±3078.80) for total PA, 1937.65 (±1992.39) for vigorous PA, 827.66 (±1049.81) for moderate PA and 1304.87 (±1031.65) for PA walking intensity. 73.4% of the participants met the PA recommendations. Nonparametric tests revealed differences by gender, age, educational level and speleological expertise. Women, the middle group age, doctorate and vocational training students, and beginners were less active than their counterparts. The findings provide important contributions towards the positioning and understanding of speleology as a sport and physical activity practice

Relation between physical activity and academic performance in 3rd-year secondary education students

The main aim of this study was to analyze the relationship between the amount of physical activity and academic performance in 3rd-year secondary education students. The sample was taken from three secondary schools in the area of Barcelona. 284 students (158 girls, 126 boys) with an average age of 14.7 yr. participated. The International Physical Activity Questionnaire was used by students to self-report their amount of physical activity. Students’ academic records were obtained for comparisons. Results showed that there was a linear relationship between academic performance and physical activity; nevertheless, there was a trend to stronger correlation when modeling the relationship between these variables with a quadratic equation. Further research should focus on whether academic performance and physical activity might be better explained with a second-order equation

Nature-based Tourism or Mass Tourism in Nature? Segmentation of Mountain Protected Area Visitors Using Self-Organizing Maps (SOM)

Mountain protected areas play a fundamental role in the conservation of natural environment and at the same time provide the population with social benefits such as offering space for leisure and recreation. Understanding motivations and behavior of protected area visitors is crucial to effectively manage vulnerable areas. Our objective was to identify the profiles of visitors to a heavily used tourist destination—Kasprowy Wierch within the Tatra National Park (Poland), using the self-organizing maps (SOM) analytical method. In order to explore the socio-demographic and behavioral characteristics of the visitors a total sample of 2488 respondents were interviewed on site. Self-organizing map analysis is based on cerebral processes for managing and storing information in order to classify subjects and/or find relationships among variables. As a result, four heterogeneous tourist profiles were identified. Interestingly, two of these groups (Cluster 1 and Cluster 3), which were found to be the most challenging groups for management purposes, visited the national park for reasons other than its natural attractions. Especially, one sub-segment of Cluster 3 was mainly motivated by the possibility to use a cable car, admiring views and stayed within close proximity of the upper cable car station. Less than a half of visitors to Kasprowy Wierch (42%) were seeking a nature experience during their trip (Cluster 2 and Cluster 4). The results bring a new point of view in the discussion on visitor management within Kasprowy Wierch region, in particular by overlapping presented visitor segmentation with trip types and/or purchased cable car tickets. Within international context, we highlight the SOM technique as a valuable tool in profiling of tourists and underline the problem of the existence of mass tourism destinations within protected areas

Physical activity, physical fitness and academic achievement in adolescents: a self-organizing maps approach

The relationship among physical activity, physical fitness and academic achievement in adolescents has been widely studied; however, controversy concerning this topic persists. The methods used thus far to analyse the relationship between these variables have included mostly traditional lineal analysis according to the available literature. The aim of this study was to perform a visual analysis of this relationship with self-organizing maps and to monitor the subject's evolution during the 4 years of secondary school. Four hundred and forty-four students participated in the study. The physical activity and physical fitness of the participants were measured, and the participants' grade point averages were obtained from the five participant institutions. Four main clusters representing two primary student profiles with few differences between boys and girls were observed. The clustering demonstrated that students with higher energy expenditure and better physical fitness exhibited lower body mass index (BMI) and higher academic performance, whereas those adolescents with lower energy expenditure exhibited worse physical fitness, higher BMI and lower academic performance. With respect to the evolution of the students during the 4 years, ~25% of the students originally clustered in a negative profile moved to a positive profile, and there was no movement in the opposite direction
