Cognitive and Academic Outcomes of Fundamental Motor Skill and Physical Activity Interventions Designed for Children with Special Educational Needs: …
2022
This systematic review aimed to investigate the methodological quality and the effects of fundamental motor skills and physical activity interventions on cognitive and academic skills in 3- to 7-year-old children with special educational needs. The review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) statement. A literature search was carried out in April 2020 (updated in January 2022) using seven electronic databases, including ERIC, Scopus, Web of Science, PsycINFO, CINAHL, PubMed, and SPORTDiscus. The methodological quality of the studies was assessed with Effective Public Health Practice Project (EPHPP) Quality Asses…

Associations between physical activity, motor skills, executive functions and early numeracy in preschoolers
2022
We investigated direct and indirect cross-sectional associations of physical activity, fundamental motor skills, executive functions, and early numeracy in preschoolers. The participants were 214 preschoolers aged three to five years. Time spent in moderate and vigorous physical activity was measured by hip-worn accelerometers and fundamental motor skills using the tasks assessing locomotor, object control, and stability skills. Inhibition/switching and working memory/updating, as components of executive functions, were assessed by computerized tests and a standardized test was used to assess early numeracy. Path analyses were used to examine direct and indirect associations between the con…
I GESTI MOTORI NELLE SCOLIOSI MINORI
2008
Per scoliosi s'intende una deviazione laterale permanente della colonna vertebrale, che si accompagna ad alterazioni anatomiche delle vertebre e delle altre strutture di sostegno del tronco. La Scoliosis Research Society definisce la scoliosi come una curva (> 10 gradi Cobb) sul piano frontale che si manifesta con un'inclinazione laterale, che comporta l'allontanamento di un certo numero di vertebre dalla linea mediana; questa modificazione dà origine ad una curva laterale, caratterizzata da un apice, essendo la vertebra apice la più scostata dall’ asse mediano, e da vertebre neutre o vertebre limite, alle estremità della curva, dove le articolazioni intervertebrali ritornano verso la linea…
Modèle des voies réflexes et cérébelleuses, permettant le calcul de fonctions inverses et la commande d'un segment mécanique mobile
2004
14/07/2004; La commande et le contrôle des mouvements des membres par les voies cérébelleuses et réflexes sont modélisées au moyen d'un circuit dont la structure est déduite de contraintes fonctionnelles. 1/ La première contrainte est que les mouvements rapides des membres doivent être précis, quoiqu'ils ne puissent pas être commandés en boucle fermée au moyen de signaux sensoriels. Les voies qui préparent les ordres moteurs doivent donc contenir des fonctions inverses approximées des fonctions biomécaniques du membre et des muscles. Or une telle fonction peut être calculée au moyen de boucles de rétroaction parallèles, dont la structure est comparable à l'anatomie des voies cérébelleuses. …
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Computing temporal sequences associated with dynamic patterns on the C. elegans connectome
2021
AbstractUnderstanding how the structural connectivity of a network constrains the dynamics it is able to support is a very active and open area of research. We simulated the plausible dynamics resulting from the known C. elegans connectome using a recent model and theoretical analysis that computes the dynamics of neurobiological networks by focusing on how local interactions among connected neurons give rise to the global dynamics in an emergent way, independent of the biophysical or molecular details of the cells themselves. We studied the dynamics which resulted from stimulating a chemosensory neuron (ASEL) in a known feeding circuit, both in isolation and embedded in the full connectome…

Rotor bar breakage data obtained from fatigue test
2019
The data hereby provided was acquired during a fatigue test developed at the Department of Electrical Engineering, Universitat Politècnica de València (Universidad Politécnica de Valencia, Spain) in 2011 by PhD student Vicente Climente-Alarcon under supervision of Prof. Martin Riera-Guasp. The fatigue test involved subjecting a 1.5 kW, 1 pole pair induction motor to severe cycling until a bar breakage naturally developed. The cycling consisted of a Direct-on-line (DOL) startup followed by a stationary operation period of at least 10 seconds. A plug stopping was added at the later stages of the test. To maximize the possible damage to the rotor cage, a high load inertia caused heavy (long) s…
Evaluación en conductores de la capacidad de atención visual a través del desarrollo de los movimientos oculares
2015
La circulación vial es una realidad social, compleja y dinámica en las sociedades avanzadas, siendo la habilidad para conducir seguro el resultado de la interacción entre el individuo, el coche y el entorno. Dentro del factor humano las condiciones visuales, la capacidad cognitiva, y la habilidad, son determinantes para responder adecuadamente ante la multitarea compleja que implica al entorno cambiante de la conducción. A través de una óptima búsqueda y correcta atención se reconoce, analiza y procesa la información visual, lo cual permite comprender, organizar y actuar ante el espacio visual externo dinámico. Cualquier elemento o factor perturbador de la visión, bien sea por inducir distr…
