Comparison of conventional hamstring/quadriceps ratio between genders in level-matched soccer players
2017
Abstract Objectives: The main goal of our study is to compare the hamstring/quadriceps (H/Q) ratio at different knee angles between level-matched male and female soccer players and to determine whether differences in the H/Q ratio exist between the dominant and the non-dominant leg. Methods: A cross-sectional study design was used to compare an isometric H/Q ratio and functional isokinetic ratio (between hamstring in eccentric contraction and quadriceps in concentric contraction) between males (n = 14) and females (n = 14). These ratios were studied at two different speeds of movement (60° s−1 and 180° s−1) and in five different positions (40°, 50°, 60°, 70° and 80° degrees of knee flexion)…
Entrenament específic de la força i l'estabilitat lumbopélvica per a jugadors i jugadores de handbol
2020
El document forma part dels materials docents programats mitjançant l'ajut del Servei de Política Lingüística de la Universitat de Valencia. Aquest article pretén mostrar una visió més específica i integradora del treball de la musculatura lumbopélvica basant-nos en la literatura científica. El treball exposat presenta una forma d'entrenament planificada, pensada, intencionada i integradora de la zona mitjana. El cos és un tot, totes les cadenes cinètiques passen per la zona mitjana i s'ha de treballar d'acord amb els requeriments de l'esport.
Atomic force microscopy visualization of injuries in Enterococcus faecalis surface caused by Er,Cr:YSGG and diode lasers
2014
Aim: To visualize by Atomic Force Microscopy the alterations induced on Enterococcus. faecalis surface after treatment with 2 types of laser: Erbium chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser and Diode laser. Material and Methods: Bacterial suspensions from overnight cultures of E. faecalis were irradiated during 30 seconds with the laser-lights at 1 W and 2 W of power, leaving one untreated sample as control. Surface alterations on treated E. faecalis were visualized by Atomic Force Microscopy (AFM) and its surface roughness determined. Results: AFM imaging showed that at high potency of laser both cell morphology and surface roughness resulted altered, and that several ce…
Should we use gait speed in COPD, FEV 1 in frailty and dyspnoea in both?
2016
Frailty is a progressive physiological decline in multiple organ systems marked by loss of function, loss of physiological reserve and increased vulnerability to disease [1]. Biological (inflammation and loss of hormones), clinical ( e.g. sarcopenia and osteoporosis) and social factors are involved in frailty onset, evolution and prognosis [2, 3]. Links between frailty, dyspnoea and chronic respiratory diseases represent a novel and practical approach
Respostas mecânicas da musculatura do joelho de bodyboarders de alto nível durante o desempenho

INTRODUCTION: bodyboarding is a kind of surfing that has been growing very rapidly over the last decade and has now developed into one of the fastest growing water sports in the world.OBJECTIVES: evaluate the effects of fatigue on rectus femoris RF, vastus lateralis VL and vastus medialis VM and biceps femoris BF and semitendinosus ST during a high-level bodyboard competition using tensiomyography TMG.METHODS: subjects were 11 highly experienced years of practice: 15, SD=4.65 male bodyboarders age: 28.17, SD=2.89, body weight: 74.83, SD=6.13kg; height: 179.25, SD=3.93cm; BMI: 23.29, SD=1.81 participating in the final of the 2010 Spanish championship.RESULTS: the fatigue is especially eviden…

La tesi tracta de contribuir a l'estudi del treball forçat del franquisme, les seues interrelacions amb els camps de concentració, el sistema carcerari i altres àmbits repressius, rellevant historiogràficament per ser una matèria encara poc investigada i de gran importància per al coneixement de la repressió franquista, que tan encarnada està en la construcció i duració de la Dictadura. Per això aborda el procés de configuració i evolució de la repressió articulada pel franquisme en unitats de treball forçat durant la guerra civil i la postguerra, per a sotmetre i aprofitar els presoners republicans i els considerats desafectes al nou règim sorgit d´ella, procedents de la província de Valèn…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2006
Resumen basado en el de la publicación Resumen en inglés Se muestra el importante papel de uno de los instrumentos más comunes, el péndulo, en la construcción del paradigma newtoniano. Del análisis de algunas aplicaciones interesantes llevadas a cabo por los mejores científicos de ese tiempo, se concluye que el uso apropiado del péndulo en el aula puede ser una manera fácil de introducir la evolución histórica y epistemológica de conceptos físicos básicos.
