Global research trends on cardiac troponin and physical activity among pediatric populations: a bibliometric analysis and science mapping study.

Background: Cardiac troponin (cTn) is a reliable marker for evaluating myocardial damage. cTn is a very specific protein involved in myocardial injury, and it is a key factor in the diagnosis of coronary syndromes. Bibliometric analysis was applied in the present work, with the main goal of evaluating global research on the topic of cardiac troponin in pediatric populations. Methods: Publications about cardiac troponin and physical activity in pediatric populations were retrieved from the Social Sciences Citation Index (SSCI) and the Science Citation Index Expanded (SCIE) of the Web of Science Core Collection, and they were then analyzed. The study was able to identify the key bibliometric indicators, such as publications, keywords, authors, countries, institutions, and journals. For the analysis, VOSviewer, R-based Bibliometrix (4.2.2), and MapChart were used. Results: Initially, 98 documents were identified; however, once inclusion and exclusion criteria were applied, the number of documents decreased to 88. The search yielded 79 original research articles and 9 reviews, almost all of which were published in the past 2 decades. The total number of citations (Nc) of the retrieved publications was 1,468, and the average number of citations per article (Na) was 16.68. In general, 508 authors were found to have participated in research about troponin; they were associated with 256 institutions, and their work was published in 65 different journals from around the world. The authors hailed from 30 countries and/or regions. The year 2022 was the most productive year for the publication of the selected documents. The bibliometric analysis provided information regarding levels of cooperation among authors and institutions. In fact, China, the United States, and England were the most productive nations, and the journal with the greatest number of publications on the topic was Pediatric Cardiology. Summary: The number of publications and the trend line show that research on this topic has not yet reached a stage of maturity. There are referent investigators, countries, and institutions that have laid the foundations for subsequent studies on the analyzed topic.

Sport practice and depression during adolescence: Special emphasis on performance level and sport discipline.

OBJECTIVES: Depression is one of the most prevalent diseases worldwide, with almost half of the adolescent population affected according to latest research. Given this serious burden of disease, research points toward interventions that could effectively fight this disease in this population subset. One of these pivotal interventions is physical activity, although the effects of different sport types and sport performance level on depression have not yet been studied in adolescent populations. Accordingly, the objective of the current study was to assess the relationship between depressive symptoms, sport type and performance level in a large adolescent population. DESIGN: Cross-sectional study assessing a large cohort of adolescents through self-reported data. METHODS: 10,248 participants aged 11-19 years old answered questionnaires regarding depressive symptoms and sporting habits and were classified according to their sport performance level: from physically inactive to internationally competitive. RESULTS: Girls reported higher incidence of depressive symptoms than boys, difference that further increased during late adolescence. Performance level was related to depressive symptoms: inactive participants reported the highest depressive scores while internationally competitive athletes reported the lowest. However, there were no differences between competitive athletes of different performance levels. Further, sport type had a small influence on depressive symptoms. CONCLUSIONS: All these findings result in a potential guideline for future research and community health recommendations: as long as sufficient physical activity levels are met and the adolescent engages in sporting activities, the protection against depressive symptoms remains largely unrelated to the sport type and the level at which he or she performs.

Home Advantage and Sports Performance: Evidence, Causes and Psychological Implications / Competir en casa y rendimiento deportivo: evidencias, causas e implicaciones psicológicas

Home advantage in competitive sports is well documented despite some contradictory results. Previous studies have identified 5 main causes of home advantage in competitive sports: crowd, familiarity, travels, rules and territoriality. Moreover, several studies have proposed the influence of these factors over psychological and behavioral states in athletes, coaches and referees. The present review summarizes the available scientific evidences about home advantage in sport and tries to identify the environmental and psychological causes of this phenomenon.

Competir de local constituye una ventaja ampliamente documentada en el ámbito deportivo. Los estudios previos han identificado cinco causas principales que permiten explicar la ventaja que ello supone: la presencia de aficionados, la familiaridad con el entorno, la ausencia de viajes, la aplicación de las normas y el sentimiento de territorialidad. Además, algunos estudios indican que estos factores influyen sobre el estado psicológico y el comportamiento tanto de los deportistas como de los entrenadores y árbitros. Esta revisión pretende recoger las actuales evidencias científicas sobre la ventaja que supone competir en casa, tratando de identificar las causas ambientales y psicológicas que explican este fenómeno en el ámbito deportivo.

A produtividade científica em WoS e no índice h de hirch da área de Educação Fisica na Espanha e Brasil: produtividade e comparação entre países / Web of science production and the index h hirchs of Physical Education teachers. comparative study between Spain and Brazil

Este trabalho tem como objetivo analisar a produção dos docentes da área de Educação Física(EF) na Espanha e no Brasil, segundo os artigos publicados em revistas indexadas na base de dados Web of Science (WoS). A metodologia consiste em um estudo comparativo e correlacional de análises de documentos. Os participantes foram professores com publicações na base de dados WoS. A mostra esteve formada por 373 professores, entre os quais 108correspondem à área de EF do Brasil e 265 correspondem à área de EF Espanhola. Os resultados indicam que os professores da área de EF na Espanha tem um Índice h de 2.65 e 7.49 artigos por investigador. Os professores brasileiros tem um Índice h de 6.05 e a média por autor é de 30.91 artigos por pesquisador. As correlações entre número de artigos por investigador e índice H são positivas r=.91 no caso da Espanha y r=.86 e no Brasil. As revistas em que mais publicam os professores brasileiros e espanhóis são Medicine and Science in Sports and Exercise e Journal of Strength and Conditioning Research.

This paper aims to analyse the production of Physical Education (PE) teachers in Spain and Brazil in view of the papers published in journals listed in the Web of Science (WoS) database. The methodology consists in a comparative and co-relational study of document analysis. The participants of this study are teachers with published papers listed in the WoS database. The sample is made up of 373 teachers; 108 of them were PE teachers from Brazil and the remaining 265 were PE teachers from Spain. The results indicate that Spanish PE teachers had an h index of 2.65 and 7.49 papers per researcher. By contrast, Brazilian teachers had an h index of 6.05 and an average of 30.91 papers per researcher. The correlations between the number of papers per researcher and their H index are positive r=.91 in the case of Spain, and r=.86 in the case of Brazil. The most popular journals of publication for both Brazilian and Spanish teachers are Medicine and Science in Sports and Exercise and Journal of Strength and Conditioning Research.
