Se pretende valorar el nivel de condición física de escolares de Educación Primaria en relación a su nivel de actividad física y determinar las posibles diferencias en cuanto al género en relación al nivel de actividad física. Se seleccionaron 420 participantes (10.04 ± 1.26 años, una masa de 41.29 ± 11.56 kg, una talla de 142.44 ± 9.32 cm. y un IMC de 20.04 ± 4.24 kg./m2), los cuales fueron divididos en tres grupos en relación a su nivel de actividad física y a su vez, se consideró el género de los mismos. Se realizó una valoración antropométrica (masa, talla, IMC, Ratio cintura-cadera), fuerza isométrica manual (mano dominante y no dominante), flexibilidad isquiosural, evaluación del salto vertical (CMJ) y capacidad cardiorrespiratoria (estimación del VO2 max.). Los resultados muestran unas características de composición corporal consideradas como normales para la población infantil, existiendo escasas diferencias en cuanto al nivel de actividad física. Sí se observan diferencias en cuanto a la capacidad cardiorrespiratoria. Se observan diferencias respecto al género en cuanto a la potencia de piernas, siendo mayor en los chicos que en las chicas. A su vez, las chicas obtienen mayores valores de flexibilidad. Palabras clave: condición física, género, educación primaria, nivel de actividad física.Abstract: To assess the fitness level of primary schoolchildren in relation to their physical activity level and identify potential gender differences in regard to the level of physical activity. 420 subjects (10.04 ± 1.26 years, 41.29 ± 11.56 mass kg., 9.32 ± size 142.44 cm. and 20.04 ± 4.24 BMI of kg/m2) we selected. They were divided into three groups regarding their level of physical activity An anthropometric (mass, height, BMI, waist-hip ratio), and physical fitness (handgrip strength, vertical jump, flexibility and maximal oxygen consumption) were evaluated. The results show lower difference on anthropometric characteristics. There are few differences in the level of physical activity, basically in fitness cardiorespiratory. Male show better values of vertical jump than female. In turn, female have higher values of flexibility. Key words: fitness level, gender, primary school, physical activity
The aim of the present study was to analyse the scientific production in the sport of badminton. Publications were collected from the main collection of "Web of Science" platform, specifically from Science Citation Index Expanded (SCI-EXPANDED), Social Sciences Citation Index (SSCI) and Art & Humanities Citation Index (A&HCI) databases for the period 2007-2017, obtaining a total of 122 items. The analysis assessed annual trend of published articles from 2007 to 2017, country distribution of publications, first author's institution distribution of publications, first author's productivity, average number of authors per article, major journals, average number of citations per article, thematic area, sample characteristics and modality. Among the most relevant conclusions are the number of publications on badminton has increased significantly from 2007 to 2017, more specifically in the last 4 years (2014-2017); Asian and European countries have the highest productivity index, both continents with great trend in badminton, coinciding, in turn, with institutions and first authors; health and training are the most studied thematic areas, whose main disciplines are sports medicine and theory of sports training. This type of studies provides baseline information on future research directions in badminton.
Resumen: El objeto del estudio es analizar cómo los ciclos económicos afectan a la inversión en el tercer sector del deporte y a los resultados deportivos internacionales. Se comparan los modelos de España y Reino Unido. Se seleccionaron los resultados olímpicos de ambos países en los últimos 20 años (Sídney 2000; Atenas 2004; Pekín 2008; Londres 2012 y Río 2016. Los resultados muestran como España ha ido disminuyendo la inversión pública en deporte desde la crisis, pero ha logrado mantener sus resultados deportivos en los Juegos Olímpicos. Esto evidencia una posible mejora de los recursos públicos y de la generación de recursos propios. Reino Unido muestra una recuperación económica mucho más sólida, que ha potenciado sus resultados deportivos, casi doblando el número de medallas en el periodo poscrisis. Se constata una mayor eicacia y eiciencia del modelo de Reino Unido que necesita menos de la mitad de deportistas olímpicos para conseguir excelentes resultados, generando un coste de medalla por habitante un 50% menor que España. Palabras clave: resultados deportivos, Juegos Olímpicos, federaciones deportivas, economía deporte, subvenciones. . he results show how Spain has been decreasing public investment in sports since the crisis, although maintaining its sport results. his shows an improvement of public resources and its own resources. UK shows a much stronger economic recovery, which has boosted its sports results as it has almost double the medal number in the post crisis period. here is a greater efectiveness and eiciency of the UK model that needs to send less than half Olympic athletes to get excellent results, generating a medal cost per inhabitant 50% lower than Spain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
