Effect of Training-Induced Changes in Achilles Tendon Stiffness on Muscle–Tendon Behavior During Landing
2018
During rapid deceleration of the body, tendons buffer part of the elongation of the muscle–tendon unit (MTU), enabling safe energy dissipation via eccentric muscle contraction. Yet, the influence of changes in tendon stiffness within the physiological range upon these lengthening contractions is unknown. This study aimed to examine the effect of training-induced stiffening of the Achilles tendon on triceps surae muscle–tendon behavior during a landing task. Twenty-one male subjects were assigned to either a 10-week resistance-training program consisting of single-leg isometric plantarflexion (n = 11) or to a non-training control group (n = 10). Before and after the training period, plantarf…
The PROMISE study protocol: a multicenter prospective study of process optimization with interdisciplinary and cross-sectoral care for German patient…
2021
Background and purpose — Knee and hip replacement are common and increasing procedures, and an optimized care process that could be implemented in different settings would be useful. The PROMISE trial investigates whether a new care process works equally in different German settings and how the results compare with current non-standardized care. Patients and methods — This multi-center prospective mixed-method study includes 2,000 German patients receiving arthritis-related hip or knee endoprostheses. An interdisciplinary and cross-sectoral care process was developed and implemented in 3 German hospitals with different levels of care, and corresponding rehabilitation centers were included t…
Impingement of the Sciatic Nerve due to a Protruding Acetabular Cage Rim
2020
Abstract Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it wa…
Longer Nap Duration During Ramadan Observance Positively Impacts 5-m Shuttle Run Test Performance Performed in the Afternoon.
2022
It is well-documented that changes in the rhythm of life during Ramadan affect sleep schedules (i.e., interruption of night sleep patterns) and are likely to have negative effects on physical and cognitive performances. The aim of the present study was to examine the effect of different naps opportunities’ durations during Ramadan on performance of short-duration repetitive maximal exercise and perception of effort. Fifteen physically active men (age: 21 ± 3 years, height: 177 ± 6 cm, body-mass: 73 ± 10 kg) performed a 6 × 30-s shuttle run test after a 25-min nap (N25), a 45-min nap (N45), and in a no-nap condition (NN) during three experimental periods: ∼2 weeks before Ramadan (BR), the la…
Principios rectores en la adopción de diligencias limitativas de los derechos reconocidos en el art. 18 ce
2021
Criminal Procedure Law reform carried out in 2015 requires, in order to adopt the investigation proceedings that limit the rights recognized by art. 18 Spanish Constitution, to respect the guiding principles of specialty, suitability, exceptionality, necessity and proportionality. This article aims, departing from the legal text and considering existing jurisprudence, to unveil the true meaning of these principles.
Notes on Shore Flies (Diptera: Ephydridae) from Finland and north-western Russia
2015
The recent checklist of the Ephydridae of Finland by Zatwarnicki and Kahanpää (2014) mentioned 13 ephydrid species as new for Finland without further details. This paper presents detailed records for those species and a few other species of interest. Four species are recorded for the first time from Russia. Trimerina indistincta Krivosheina, 2004 is herein considered as a new junior synonym of Trimerina microchaeta Hendel, 1932, syn. nov.
It takes time to see the menu from the body: an experiment on stable isotope composition in freshwater crayfishes
2015
For many applications and ecological studies in which wild individuals are brought to laboratory it would be essential to know accurately how fast novel diet is reflected in composition of different tissues. To study the effects of two different diets on the stable isotope composition of freshwater crayfish muscle and hemolymph, we conducted a three month experiment on noble crayfish (Astacus astacus) and signal crayfish (Pacifastacus leniusculus) by feeding them sweet corn (Zea mays) or Baltic herring (Clupea harengus membras) as novel food. During the experiment, the crayfish were given 0.4 g of selected food daily and the amount consumed was recorded. The samples for the stable isotope a…
Estudio semántico-pragmático de las relaciones de contraste y sus marcas en lengua inglesa.
2005
El presente trabajo estudia las relaciones de contraste (RC) y su expresión en el discurso escrito en lengua inglesa. El contraste es una noción muy empleada en lingüística, aunque su definición teórica resulta controvertida, y hay pocos estudios prácticos sobre sus formas de expresión. En una primera parte, revisamos los estudios sobre dicha noción desde distintas perspectivas lingüísticas, principalmente la semántica y la lingüística textual. Abordamos la problemática de la definición de esta noción, a partir de su definición como relación conceptual, de su relación con otras nociones (adversación, concesión) y categorías cognitivas (temporalidad, condición), incidiendo en la polisemia de…
Negotiation of form: Analysis of Feedback and student response in two different contexts.
2005
In the first part of the dissertation, which corresponds to the theoretical one, a series of cognitive theories are analysed; we also deal with the study of learning strategies; we analyse several studies on the interaction in the field of discourse analysis; we also describe different studies related to discourse and the acquisition of a new language and finally classroom discourse is analysed according to different aspects.Once these aspects are dealt with, we offer a bibliographic review on the topic studied in relation to the aspect of feedback. This review begins with works written in the 1960's and ends nowadays. We describe the works attending to aspects such as main objective, metho…
La selección de léxico en la enseñanza del español como lengua extranjera. Su aplicación al nivel elemental en estudiantes francófonos.
2003
La presente investigación tiene como objetivo la propuesta de criterios de selección del léxico español como lengua extranjera en el sistema de enseñanza secundaria francés. Este estudio se ha centrado concretamente en los alumnos francófonos de nivel elemental (4ème y 3ème) entre 13 y 15 años, que estudian el español como segunda lengua extranjera. Con el fin de conocer los estilos de enseñanza-aprendizaje del vocabulario practicados en las aulas, de determinar las carencias de la selección léxica y realizar propuestas de mejora, la autora ha efectuado diversas tareas: a) una encuesta de setenta y cinco preguntas abiertas y cerradas dirigida a un amplio número de profesores de español de l…
