Scientific production has increased exponentially in recent years. It is necessary to find methodological strategies for understanding holistic or macro views of the major research trends developed in specific fields. Data mining is a useful technique to address this task. In particular, our study presents a global analysis of the information generated during last decades in the Sport Sciences Category (SSC) included in the Web of Science database. An analysis of the frequency of appearance and the dynamics of the Author Keywords (AKs) has been made for the last thirty years. Likewise, the network of co-occurrences established between words and the survival time of new words that have appeared since 2001 has also been analysed. One of the main findings of our research is the identification of six large thematic clusters in the SSC. There are also two major terms that coexist ('REHABILITATION' and 'EXERCISE') and show a high frequency of appearance, as well as a key behaviour in the calculated co-occurrence networks. Another significant finding is that AKs are mostly accepted in the SSC since there has been high percentage of new terms during 2001–2006, although they have a low survival period. These results support a multidisciplinary perspective within the Sport Sciences field of study and a colonization of the field by rehabilitation according to our AK analysis.
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.
Las relaciones sociales son de vital importancia para el correcto desarrollo de los seres humanos, y junto con la actividad física, la obesidad y la autoestima forman un conjunto de factores que pueden ser capaces de retroalimentarse entre sí, pero que hasta donde los autores saben, solo se han analizado por separado. Por tanto, el principal objetivo de estudio será realizar un análisis multifactorial que incluya todas las variables anteriormente mencionadas. Un total de 60 niños de edades comprendidas entre los 7 y los 13 años formaron la muestra de este estudio. Los instrumentos utilizados para las mediciones de las diferentes variables de estudio fueron el PAQ-C, la escala de autoestima de Rosenberg y una adaptación del Bull-S Test. Una vez recogidos todos los datos se realizó un análisis con Self-Organizing Maps mediante el software Matlab R2008a y la SOM toolbox para Matlab. Los resultados obtenidos en este trabajo muestran la repercusión del Índice de Masa Corporal sobre los niveles de autoestima y las relaciones sociales, y la posible retroalimentación mutua entre estos dos últimos factores.Abstract. Social relationships are vital for the proper development of humans, and along with physical activity, obesity, and self-esteem, they form a set of factors that may be able to feed each other; however, as far as the authors know, they have only been analyzed separately. Therefore, the main objective of this study is to carry out a multifactorial analysis that includes all the aforementioned variables. A total of 60 children between 7 and 13 years of age formed the sample of this study. The instruments used for the measurements of the different study variables were the PAQ-C, the Rosenberg self-esteem scale, and an adaptation of the Bull-S Test. Once all the data was collected, an analysis with Self-Organizing Maps was made, using the Matlab R2008a software and the SOM toolbox for Matlab. The results obtained in this work show the repercussion of Body Mass Index on the levels of self-esteem and social relations, and the possible mutual feedback between the last two factors.
Nowadays, the study of kinanthropometric parameters is an important tool for both early talent selection and for evaluating the efficacy of a training program. This study aimed to determine the anthropometric characteristics, body composition indicators and somatotype components of individual (athletics, swimming and triathlon), collective (handball and volleyball) and fight (karate and taekwondo) sportsmen and sportswomen from the Valencian Sports Technification Centre. This study involved a total of 62 men and 56 women, they were divided in three subgroups, including individual (athletics, swimming and triathlon), collective (handball and volleyball) and fight (karate and taekwondo) sports. The assessment was carried out according to the one established by the International Society for Advancement of Kinanthropometry (ISAK). For men, the highest value of femur breath, ectomorphy and medial calf and front thigh skinfolds are obtained for triathletes, athletics, volleyball and karate, respectively. The highest values of triceps, biceps and abdominal skinfolds, relaxed arm girth, endomorphy and body fat percentage are shown for taekwondo, while the other highest values are obtained with handball. For women, the highest value of ectomorphy is obtained for athletics. The identified kinanthropometric parameters are useful when comparing between sports and sports subgroups for the selection of subjects and to help in their performance assessment.

RESULTS 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 as any other. The most mediatic professional sporting events received great attention in Twitter while grassroots and women’s sport were relegated to a residual role.

In the context of pediatric physical exercise, the analysis of factors affecting postural control (PC) provides insight into the development of sport-specific motor skills. This study aims to evaluate the static PC during single-leg stance in endurance, team and combat athletes from the Spanish National Sport Technification Program. A total of 29 boys and 32 girls, aged 12 to 16 years old, were recruited. Centre of pressure (CoP) was measured on a force platform in standing position for 40 s under two sensorial and leg dominance conditions. Girls showed lower MVeloc (p < 0.001), MFreq (p > 0.001) and Sway (p < 0.001) values than boys in both sensorial conditions (open and closed eyes). The highest values in all PC variables were observed with eyes closed in both genders (p < 0.001). Sway values were lower in boys combat-athletes compared to endurance athletes in two sensorial conditions and with non-dominant leg (p < 0.05). Young athletes in their teens enrolled in a Sport Technification Program have shown differences in PC when comparing different visual conditions, sport disciplines and gender. This study opens a window to a better understanding of the determinants of PC during single-leg stance as a critical element in the sport specialization of young athletes.
