Challenging serve myths in doubles tennis

2021

Doubles tennis has received little interest from quantitative research to date. Coach-led anecdotes therefore abound. The aims of this study were therefore to evaluate the veracity of the following common anecdotes: (a) serving teams have an advantage regardless of the length of the point; (b) serving teams have a greater advantage with new balls; (c) regular teams perform better when serving than new teams and (d) serving teams decrease their performance during break points. Data from doubles hard-court and clay-court tennis were collated for 52 doubles teams during 2018 ATP tournaments. Results revealed that the advantage of serving teams was evident on the points lasting up to 4 shots. …

Impacto de las recomendaciones sobre la vacunación del tétanos-difteria en el ámbito laboral

2017

Resumen Objetivo El objetivo de nuestro estudio es evaluar el impacto de las recomendaciones del Ministerio de Sanidad y Consumo en cuanto a la vacunacion en una mutua colaboradora con la Seguridad Social (FREMAP). Metodo Se trata de un estudio observacional retrospectivo de la vacunacion de tetanos-difteria (Td) en adultos, en FREMAP, entre enero de 2012 y diciembre de 2013. Resultados Se han registrado 126.101 accidentes susceptibles de vacunacion de Td, de los cuales han sido vacunados 11.468 (9%). No ha habido diferencias significativas en cuanto a si fueron accidentes incapacitantes o no, ni en cuanto a sexo. Se han encontrado diferencias significativas en el grupo de edad 46-55 anos, …

La rétropulsion du sujet âgé: mise au point sur un symptôme grave et proposition d'une échelle pour une évaluation quantifiée

2007

Resume Propos Bien qu'il n'existe a l'heure actuelle aucune donnee epidemiologique sur la retropulsion, ce trouble postural semble relativement frequent chez le sujet âge fragile. Actualites et points forts La retropulsion se caracterise par un dejettement posterieur du tronc en position assise, une insuffisance d'avancee du tronc dont la projection du tronc au sol est situee en arriere de la base de sustentation lors du passage assis–debout et une tendance a la chute en arriere en position debout. Plusieurs situations pathologiques aussi bien somatiques (lesions cerebrales degeneratives, ischemiques, traumatiques), que psychosomatiques (syndrome de desadaptation psychomotrice, alitement pr…

A Self-Determined Exploration of Adolescents’ and Parents’ Experiences Derived From a Multidimensional School-Based Physical Activity Intervention

2022

Purpose: Adolescents’ and parents’ experiences within a multidimensional school-based physical activity intervention grounded on self-determination theory were explored. Method: Qualitative data from 29 adolescents (aged 15–17 years) and three parents on behalf of the total students’ families were collected via participant observation (research diary), semistructured interviews, and focus groups. Results: Adolescents perceived that the application of motivational strategies, based on self-determination theory, satisfied their basic psychological needs for autonomy, competence and relatedness, favored self-determined motivation, and gave rise to adaptive consequences (improved physical activ…

Pulsed Electric Field Processing of Fruit Juices

2018

Abstract Fruit juices and other liquid foods constitute an important source of bioactive compounds. However, the techniques used for their processing may cause alterations in their contents, and consequently they do not provide the benefits expected by the consumer. This fact has led to the increasing use of nonthermal processing technologies, such as pulsed electric field (PEF), which have been developed over recent decades as alternative technologies to thermal pasteurization of liquid foods. Researchers have previously studied the effects of PEF on the main compounds affecting the quality and the health-related properties. The reported results show that PEF could be used to pasteurize fr…

From metaphor to action : embodied language cognition

2016

Las teorias que tradicionalmente han tratado de explicar como la actividad cerebral da lugar a la cognicion se han servido de la metafora del ordenador para describir que el modo en  que el cerebro procesa informacion es transformandola en un codigo de simbolos que pueden combinarse entre si siguiendo un conjunto finito de reglas. Sin embargo, recientes estudios, con paradigmas actualizados y ayudandose de las tecnicas de neuroimagen, nos muestran que las actividades cerebrales que registramos cuando observamos un cerebro implicado en alguna tarea cognitiva son las mismas que observariamos si ese cerebro se encontrase inmerso en el procesamiento perceptivo, motor o emocional de la informaci…
