Effects of power resistance training program with elastic bands on body composition, muscle strength and physical function in older women
2020
The aim of this study was to investigate the effects of a power-strength resistance program with elastic bands on body composition, physical function, and muscle strength in older women. For such purpose, a randomized controlled trial with a pre-post-intervention design was conducted. Thus, 58 healthy, physically independent, sedentary women, aged 65-85 years, were randomly allocated to the intervention (n = 28) or control group (n = 30). Measurements of body composition (total mass, total fat mass, total skeletal-muscle mass, and body fat percentage), isokinetic muscle strength of knee flexors and extensors (at 60º/second and 180º/second), and physical performance (flexibility, agility/dyn…
Innovación pedagógica en educación física: una propuesta de orientación basada en AICLE
2015
In today's society, languages, especially English language, have acquired great relevance due to the unstoppable process of globalization. Schools must adapt to these kind of social demands. Because of this fact, methodologies such as Content Led Integrated Language Learning (CLIL) are being used more and more often. Here a didactic unit for working orienteering by using CLIL is proposed in order to demonstrate that Physical Education (PE) provides a suitable context in which the use of the language is significant and relevant. Through this proposal, it is shown the great potential of PE to enhance language learning.
Teaching Physical Education in English using CLIL Methodology: A Critical Perspective
2015
Abstract Relatively little research has been carried out in Europe on teaching Physical Education (PE) in English as a Lingua Franca (ELF) using the CLIL method. Although CLIL is widely used throughout Europe, the PE content is often limited merely to technical-practical skills without any significant links to a socio-cultural context, critical thinking and/or knowledge acquisition. The aim of this study is to integrate CLIL with the epistemological perspective of critical pedagogy applied to physical education (Kirk, 2014). A theoretical “deconstructive” method will be used to provide guidelines for teaching physical education through CLIL. A cultural content based on language, culture and…
Experimental verification of position-dependent angular-momentum selection rules for absorption of twisted light by a bound electron
2018
We analyze the multipole excitation of atoms with twisted light, i.e., by a vortex light field that carries orbital angular momentum. A single trapped $^{40}$Ca$^+$ ion serves as a localized and positioned probe of the exciting field. We drive the $S_{1/2} \to D_{5/2}$ transition and observe the relative strengths of different transitions, depending on the ion's transversal position with respect to the center of the vortex light field. On the other hand, transition amplitudes are calculated for a twisted light field in form of a Bessel beam, a Bessel-Gauss and a Gauss-Laguerre mode. Analyzing experimental obtained transition amplitudes we find agreement with the theoretical predictions at a…
High‐nuclearity mixed‐valence magnetic clusters : A general solution of the double exchange problem
1996
We report here a general solution of the double‐exchange problem in the high‐nuclearity mixed valence systems containing arbitrary number P of the electrons delocalized over the network of N (P<N) localized spins. The developed approach is based on the successive (chainlike) spin‐coupling scheme and takes full advantage from the quantum angular momentum theory. In the framework of this approach the closed‐form analytical expressions are deduced for the matrix elements of the double exchange interaction, two‐electron transfer, and three‐center interaction that can be referred to as the potential exchange transfer. For the arbitrary nuclearity mixed‐valence systems the matrix elements of all …
El Antropoceno. Riesgos y oportunidades para las nuevas generaciones
2021
Nuestro propósito en este trabajo es presentar la estrategia que venimos utilizando desde hace más de dos décadas para contribuir a implicar a diversos sectores de la ciudadanía —y, muy especialmente, a estudiantes y docentes en formación- en la comprensión de la actual situación de emergencia planetaria, caracterizada por un conjunto de graves problemas socioambientales de origen antrópico, que han conducido a denominar Antropoceno la presente etapa de la evolución del planeta. Analizaremos las causas y consecuencias de estos problemas estrechamente vinculados y que se potencian mutuamente, provocando la transgresión de diversos límites planetarios. Y nos centraremos en las posibles medida…
Influence of Walking as Physiological Training to Improve Respiratory Parameters in the Elderly Population.
2022
Walking as physiological training is reported to be an effective activity in order to beneficially influence and slow the onset of aging in healthy elderly people. However, insufficient evidence exists on how walking influences lung function in seniors. In our study, we aim to evaluate the effect of different types of walking on lung function in healthy seniors. The PubMed, Web of Science, Scopus and EBSCO Essentials databases were searched, while the methodological quality was assessed by the RoB2 tool. A total of seven studies (RCTs) published between 2002–2022 that met the eligibility criteria were analysed in this review. All participants were older adults without any specific associate…
El uso de tecnología móvil y APP en educación física
2017
La literatura documenta que los educadores físicos tienen actitudes pro-tecnológicas, interés y conocimientos similares al resto de profesorado. Sin embargo, el uso de TIC, especialmente en la fase activa es menor. Esta barrera de uso se explica porque el profesorado dispone de tecnología tradicional, anclada en espacios fijos, pero se carece de tecnología móvil y portable que pueda llevarse al lugar donde se sitúa la acción: patios y gimnasios. El objetivo del estudio fue conocer qué dispositivos móviles puede usar el profesorado durante las clases y hacer una recopilación y análisis de las aplicaciones que puede utilizar para diseñar, gestionar y evaluar la docencia. Se hizo una revisión …
Educación Física bilingüe y pedagogía crítica: una aplicación basada en el Judo
2015
Considering the impact that the introduction of Content and Language Integrated Learning (CLIL) is having in Europe, this paper presents a model of application for Physical Education in English. This model improves particularly the acquisition of a foreign language and proposes at the same time a comprehensive learning scenario based on the principles of the critical pedagogy. From the 4Cs framework of CLIL methodology («content», «communication», «culture» and «cognition») the paper offers an in-depth reflection on the possibilities of introducing the critical pedagogy approach to Physical Education, thus increasing its educational potential. First, we argue about the links between critica…
Aprendizaje Servicio en la formación inicial docente de Educación Física: Análisis de una propuesta en el contexto norteamericano
2019
Este trabajo analiza los efectos de un proyecto de Aprendizaje Servicio (ApS) sobre la Competencia de Emprendimiento Social (CES) en alumnado de Educación Física. El estudio se aborda utilizando Métodos Mixtos con triangulación metodológica. El apartado cuantitativo utiliza el instrumento Social Entrepreneurship Competency Scale (Capella-Peris, Gil-Gómez, Martí-Puig, & Ruíz-Bernardo, 2019). El estudio cualitativo se desarrolla analizando los diarios reflexivos de los participantes. Los resultados cuantitativos proporcionan evidencias respecto al efecto positivo del ApS sobre la CES. El análisis cualitativo complementa esta visión reflejando cómo se desarrolló dicha competencia, por ejem…
