Effects of self-myofascial release: A systematic review.
2015
Summary Background Self-myofascial release (SMFR) is a type of myofascial release performed by the individual themselves rather than by a clinician, typically using a tool. Objectives To review the literature regarding studies exploring acute and chronic clinical effects of SMFR. Methods PubMed and Google Scholar databases were searched during February 2015 for studies containing words related to the topic of SMFR. Results Acutely, SMFR seems to increase flexibility and reduce muscle soreness but does not impede athletic performance. It may lead to improved arterial function, improved vascular endothelial function, and increased parasympathetic nervous system activity acutely, which could b…

The construction of inequalities between girls and boys of success in physical education at the baccalaureate between girls and boys
2004
This research investigates the effect of social and school processes on explanation of the achievement's differences between girls and boys in PE, particularly when they are assessed in team sports in secondary education. The performances of girls often are lower than those of boys. Traditionally, the differentiated performances may be attributed to physiological or sociological reasons. The object of this research, conducted about 1245 pupils and theirs PE teachers, was to focus on a possible differential treatment at school between girls and boys. Teacher's perceptions about sport as a male domain influence the process in which girls receive at school a poorest learning. The relative fail…
Virtual element method for computational homogenization of composite and heterogeneous materials
2020
Abstract In this study, a two-dimensional multi-region framework, based on the use of the Virtual Element Method (VEM), is developed for computational materials homogenization and applied to different classes of widely employed heterogeneous materials. The VEM has recently emerged as a powerful generalisation of the Finite Element Method capable of dealing with very general polygonal mesh elements, including non-convex or highly distorted elements. Such features are appealing for the treatment of problems whose analysis domains present complex or statistical morphological features, which would generally require careful and time-consuming mesh/data preparation and regularization. In this wor…
A Fiber Optic Strain Gage Sensor for Measuring Preload in Thick Composite Bolted Joints
2019
Mechanical fastening is a popular choice in joining composites because of the ability to transfer high loads and the ease of assembly and disassembly. In this study, the failure behavior of composite–aluminum single lap bolted joint is investigated. In particular, the effects of varying the preload on the bolt are examined. In order to accurately measure the preload, a specialized sensor that uses a fiber Bragg grating sensor embedded in the bolt is proposed and created. This sensor is realized for the current tests but can be expanded to other applications. An experimental study of bolted single-lap joints varying the tightening torque value has been carried out and, in order to validate t…
Comment on: A critical analysis of the internal logic in the Life-Space Assessment (LSA) composite score and suggested solutions
2016
Background:An individual’s ability to live independently is commonly measured in health research interested in identifying risk factors associated with disablement processes. In order to inform clinical practice, population research has attempted to identify the contraction of “lived-space” by using various survey instruments.Problem:Studies assessing habitual movements over the environment with the Life-Space Assessment (LSA) survey instrument should carefully consider how the LSA Composite Score (LSA-CS) is computed. Until now, no publication has carefully delineated the assumptions guiding the internal logic used in the computation of the LSA-CS.Core argument:Because the internal logic o…
The effect of through-thickness compressive stress on mode II interlaminar fracture toughness
2017
Abstract The effect of through-thickness compressive stress on mode II interlaminar fracture toughness is investigated experimentally and replicated numerically. The modified Transverse Crack Tensile specimen recently proposed by the authors is used, together with an experimental device designed to apply a constant transverse compressive stress on the surface of the specimen. Experiments are conducted using IM7/8552 specimens for different compressive stresses, ranging from 0 to 100 MPa, covering all the practical applications commonly encountered in the aeronautical industry (e.g., tightened filled holes or bolted joints). It is shown that mode II interlaminar fracture toughness increases …
Visiones sobre la gamificación como estrategia metodológica inclusiva en educación primaria
2022
La aparición en las últimas décadas de metodologías más activas y cooperativas parece estar dando respuesta a algunas de las necesidades del alumnado actual, mucho más diverso y digitalizado. Entre las estrategias metodológicas, este trabajo se ha centrado en la gamificación, en analizar la percepción que tiene el alumnado, el profesorado y las familias sobre cómo esta práctica puede favorecer la creación de entornos educativos más inclusivos y colaborativos. Se presenta un estudio etnográfico llevado a cabo en un centro educativo de la Comunitat Valenciana, seleccionado intencionadamente por sus especiales características instrumentales. Las técnicas de recogida de información comprenden: …
Efectos del uso de dispositivos de realidad virtual sobre el control postural y el cybersickness en jóvenes universitarios
2021
espanolEl objetivo principal de este estudio fue analizar los efectos de jugar con sistemas de realidad virtual sobre el control postural y el cybersickness. La muestra del estudio estaba compuesta por 21 sujetos de 18 a 30 anos de edad. Todos los sujetos jugaron con un dispositivo de realidad virtual durante 30 minutos. Ademas, todos los sujetos realizaron dos pretest (30 minutos e inmediatamente antes de la prueba) y dos postest (inmediatamente y 30 minutos despues de la prueba). El control postural estatico con ojos abiertos y cerrados y el cybersickness fueron evaluados en todas las pruebas. Los resultados mostraron diferencias significativas entre el pretest 2 y el postest 1 en tres de…
Introducción del sistema PECS para la superación de las limitaciones comunicativas en un caso de síndrome de West
2016
En este estudio de caso se aborda la intervención realizada en una alumna de cuatro años, escolarizada en un aula específica de un centro ordinario, y a la que recientemente han diagnosticado síndrome de West. Aplicando, a lo largo de un trimestre en un aula de Audición y Lenguaje, el sistema de comunicación por intercambio de imágenes (PECS) se pretende superar las graves limitaciones comunicativas de la alumna. El procedimiento metodológico utilizado es mixto y las técnicas de investigación empleadas son la aplicación de test estandarizados, la entrevista, los cuestionarios, los registros de observaciones y el análisis documental. A partir del test que establece la evaluación inicial del …
