Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa

2016

The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…

Biomechanical analysis of the humeral tray positioning in reverse shoulder arthroplasty design

2017

Despite the widespread use of reverse total shoulder arthroplasty, the fundamental effects of implant configuration on certain biomechanical outcomes have not been completely elucidated especially for the most innovative prostheses. Aim of this work is to investigate the behaviour of a new reverse shoulder prosthesis, characterized by a humeral tray with a variable offset, designed to increase the range of motion and to reduce the impingement. The purposes of this study were to evaluate the effect of reverse shoulder implant design parameters on the deltoid muscle forces, required to produce abduction, and on the shoulder range of motion, in order to provide a more systematic understanding …

Linear vs. non-linear classification of winners, drawers and losers at FIFA World Cup 2014

2017

Purpose: Tactical analyses to distinguish between football teams that were more or less successful have been conducted up to now only by means of linear methods (like discriminant analysis). Concer...

Hold design supports learning and transfer of climbing fluency

2014

Being a discipline with a broad range of genres, rock climbing is an activity where participants seek to generalize the skills they learn in different performance contexts. A training strategy for achieving skill transfer was explored in a group of experienced climbers. Specifically, we tested the effect of practising on three routes, each of the same difficulty, but where handholds supported opportunities for using either a single technical action or multiple actions. Transfer of climbing fluidity in terms of the geometric index of entropy (GIE) of the hip trajectory was then assessed. We expected that learning would be induced on the route where multiple actions were usable. Results revea…

Macromolecules in Microfluidics: A Synergy for Systems Engineering

2017

Negociando el currículum en educación física. Una propuesta práctica de cogestión (Negotiating the curriculum in physical education. A practical prop…

2015

Este artículo tiene como finalidad describir críticamente el proceso de negociación del currículum en Educación Física en las etapas de secundaria y bachillerato, poniendo encima de la mesa los problemas que pueden surgir y aportando algunas soluciones para difundir su uso y aumentar de este modo la participación del alumnado en los procesos educativos. Esta propuesta está fundamentada en los resultados obtenidos en un estudio de casos en que participaron dos centros públicos de la Comunidad Valenciana: a) un grupo de 3º de secundaria con 17 alumnos y b), en una segunda fase, un grupo de 1º de bachillerato con 19 alumnos. El estudio, en que participaron los dos profesores de Educación Físic…

Development of micro chemical, biological and thermal systems in China: A review

2010

The interest in micro technologies for application in chemical, biological and thermal systems has increased considerably in China because microreactors or microfluidics in general demonstrate some remarkably advantages such as inherent miniaturization and portability, intensification of heat and mass transfer, quick analysis results, high-throughput and low consumption of reagents. This review focuses on the recent advances in the micro technologies in China including microreactor-based systems for chemical processing and analysis, biological microfluidics for DNA analysis, cell handling and analysis, separation based detection, protein based applications and immunoassays, micro heat trans…

Validation of portable 2D force binding systems for cross-country skiing

2013

The aim of the present study was to design, construct and scientifically validate a two-dimensional force measurement binding system for cross-country skiing. The system consists of two force measurement bindings. One binding was designed for analysing classic skiing (vertical and anterior–posterior [along the ski] force components) and the other one for skate (freestyle) skiing (vertical and medio-lateral [transverse to the ski] force components). Validation was accomplished using a three-step process: (1) accuracy tests for the sensors in two temperatures, (2) sport-specific imitation jump test on standard force plates in a laboratory and (3) comparing the system against force measurement…

Delayed chronic intracranial subdural hematoma complicating resection of a tanycytic thoracic ependymoma

2015

Background To demonstrate that the diagnosis of an intracranial subdural hematoma should be considered for patients presenting with acute or delayed symptoms of intracranial pathology following resection of a spinal tumor. Case description We present a case of a 57-year-old woman found to have a chronic subdural hematoma 1 month following resection of a thoracic extramedullary ependymoma. Evacuation of the hematoma through a burr hole relieved the presenting symptoms and signs. Resolution of the hematoma was confirmed with a computed tomography (CT) scan. Conclusion Headache and other symptoms not referable to spinal pathology should be regarded as a warning sign of an intracranial subdural…

Pie zambo sindrómico más allá de la artrogriposis y el mielomeningocele: tratamiento ortopédico con el método de Ponseti

2021

Resumen: Introducción: El pie zambo supone una de las malformaciones congénitas del pie más frecuentes. Generalmente la etiología es idiopática. Sin embargo, pueden presentar una causa sindrómica y asociarse con afecciones musculoesqueléticas, neurológicas o del tejido conjuntivo, recibiendo en estos casos, la denominación de pie zambo sindrómico.El tratamiento de elección del pie zambo idiopático es el método Ponseti, basado en la manipulación y yesos seriados. También se ha demostrado su utilidad en pie zambo asociado con artrogriposis y mielomeningocele, pero existen pocas publicaciones sobre la eficacia en el pie zambo sindrómico. Material y métodos: Estudio retrospectivo en seis pacien…
