Energy-related optimal control accounts for gravitational load: comparing shoulder, elbow, and wrist rotations.

2013

International audience; Gaveau J, Berret B, Demougeot L, Fadiga L, Pozzo T, Papaxanthis C. Energy-related optimal control accounts for gravitational load: comparing shoulder, elbow, and wrist rotations. J Neurophysiol 111: 4-16, 2014. First published October 16, 2013; doi: 10.1152/jn.01029.2012.-We permanently deal with gravity force. Experimental evidences revealed that moving against gravity strongly differs from moving along the gravity vector. This directional asymmetry has been attributed to an optimal planning process that optimizes gravity force effects to minimize energy. Yet, only few studies have considered the case of vertical movements in the context of optimal control. What kin…

Global data on earthworm abundance, biomass, diversity and corresponding environmental properties

2021

Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible, site-level species lists were included, as well as the abundance and biomass of individual species and ec…

Ergonomic Comparison of Four Dental Workplace Concepts Using Inertial Motion Capture for Dentists and Dental Assistants

2021

When the inventory is arranged in a dental practice, a distinction can be made between four different dental workplace concepts (DWCs). Since the prevalence of musculoskeletal diseases in dental professionals is very high, preventive solution need to be investigated. As the conventionally used DWCs have, to date, never been studied in terms of their ergonomics, this study aims to investigate the ergonomic risk when working at the four different DWCs. In total, 75 dentists (37 m/38 f) and 75 dental assistants (16 m/59 f) volunteered to take part in this study. Standardized cooperative working procedures were carried out in a laboratory setting and kinematic data were recorded using an inerti…

The implication of subcortical motor centers in voluntary human activities

2009

The main objective of the present dissertation was to analyse the subcortical implications in the preparation and execution of complex voluntary movements. Three different tasks were selected on purpose. They all are everyday activities which although functionally related have differential characteristics. The first task was the sit-to-stand manoeuvre. Simple ballistic movements are executed faster in reaction time task paradigms when the imperative signal is accompanied by a startling auditory stimulus (SAS). We examined whether this effect also occurs in complex movements such as the sit-to-stand manoeuvre, taking into account both anticipatory postural adjustments and prime movers. React…

Valoración de las capacidades físicas y cognitivas en corredores de orientación de la categoría hombres-élite.

2004

El deporte de orientación consiste en realizar un recorrido en el menor tiempo posible y con la única ayuda de un mapa y una brújula, teniendo la particularidad de que cada corredor puede elegir la ruta de desplazamiento de un control a otro. Esto propicia que nos encontremos ante un deporte en el que los aspectos perceptivo-cognitivos van a ser fundamentales.El objetivo de este estudio fue caracterizar a la población española de la categoría hombres-élite, que es la máxima categoría a nivel nacional, con el fin de poder crear pautas de entrenamiento adecuadas.Para ello, realizamos una comparativa entre los corredores de élite (total: 23 corredores) y los participantes del resto de categorí…

Estudio de los trinquetes de pilota valenciana. según criterios epidemiológicos, de opinión y biomecánicos

2010

INTRODUCCIÓN La pilota valenciana es un deporte tradicional muy arraigado en la Comunidad Valenciana cuyas modalidades, escala i corda y raspall se practican en un trinquete. Sin embargo, se ha observado una problemática en los trinquetes actuales: abandono, ausencia de estudios de mejora y carencia de una normativa que establezca las características biomecánicas de los trinquetes, como resultado de la interacción entre el jugador y la pelota con el pavimento. Por otra parte, no se han encontrado investigaciones epidemiológicas en la literatura científica sobre pilota valenciana, ni estudios que relacionen la amortiguación y la fricción con la epidemiología y/o con la mejora del rendimiento…
