Teaching Matters: Enjoyment and Job Satisfaction
2016
Teaching occurs in a complex and dynamic environment that involves other people—learners, their families and school authorities as well as the subject matter to be taught. Expectations towards the effects of teaching are high, though opinions about teachers may be harmful. What is a contemporary teacher like, then? The aim of this article is to present a portrait of an average teacher on the basis of selected empirical evidence from TALIS 2013 survey (OECD, 2014). Also teachers’ emotions and their relations with job satisfaction and overall success are discussed. Finally, empirical evidence from a case study on job satisfaction, enjoyment and success of Polish teachers of English is discuss…
Évaluation du taux de blessures chez les pratiquants de CrossFit en France
2020
Introduction Le CrossFit s’est rapidement developpe en France depuis 2012, avec actuellement plus de 230 salles affiliees. Il s’agit d’un sport a part entiere visant a optimiser la condition physique mais c’est aussi une methode de preparation physique pouvant entrer dans le cadre d’un entrainement pour une autre discipline. La reputation de ce sport dans l’opinion est d’etre traumatisant sur le plan physique. L’objectif de cette etude etait de determiner en France le taux de blessures pour 1000 heures d’entrainement et de le comparer a ceux d’autres sports. Methode Toutes les salles affiliees CrossFit de France metropolitaine ouvertes depuis au moins 1 mois au premier octobre 2015 ont ete …

Analysis of the differences in serve effectiveness between Billie Jean King Cup (former Fed Cup) and Davis Cup doubles tennis matches
2021
The doubles game has considerable relevance in professional tennis, especially in team competitions such as the Billie Jean King Cup (former Fed Cup) (BJKC) and the Davis Cup (DC). However, there are very few studies that have carried out quantitative notational analysis to provide information on the specific features of this tennis modality. The goal of this study was to analyse the differences in serve direction and effectiveness of male and female teams in matches played at BJKC and DC ties. A total of 29,207 serves; 7,578 of BJKC and 21,628 of DC matches were analysed. The data was obtained through the Hawk-Eye system. The results showed that with the first serve, both BJKC and DC team…
Social integration of Ethiopian and Eritrean women in Switzerland through informal sport settings
2021
This study investigated the role of informal sport settings (i.e. self-organised and non-voluntary sports clubs) in the social integration of Ethiopian and Eritrean women into Swiss society. Social integration seen as a multidimensional, interdependent process between the interaction of social bond, bridge and links; and two-way interaction between the migrant and local community. Thematic analysis of semi-structured interviews and focus group discussions (n���=���12, 18���51���years old) was used to understand the interplay between social integration and participation in informal sport settings. The findings indicated that such settings have become a crucial sphere for establishing and reb…
Including the Past: Performance Modeling Using a Preload Concept by Means of the Fitness-Fatigue Model
2019
Abstract In mathematical modeling by means of performance models, the Fitness-Fatigue Model (FF-Model) is a common approach in sport and exercise science to study the training performance relationship. The FF-Model uses an initial basic level of performance and two antagonistic terms (for fitness and fatigue). By model calibration, parameters are adapted to the subject’s individual physical response to training load. Although the simulation of the recorded training data in most cases shows useful results when the model is calibrated and all parameters are adjusted, this method has two major difficulties. First, a fitted value as basic performance will usually be too high. Second, without mo…
El papel del profesor en la motivación y la salud mental de los estudiantes de educación física
2016
Resumen Introducción. La teoría de la autodeterminación sugiere que los sujetos con regulaciones autónomas mostrarán mayores niveles de funcionamiento óptimo que aquellos con regulaciones controladoras. Asimismo, la teoría ha defendido la importancia que tienen los factores sociales en los procesos motivacionales. En el contexto educativo, uno de los factores sociales que tiene un papel importante en la motivación de los estudiantes es el estilo interpersonal que utiliza el profesor cuando brinda instrucciones; por tanto, aquellos ambientes que fomenten la motivación autónoma serán importantes para el desarrollo óptimo y la salud mental de los estudiantes. Objetivo. Examinar si el grado en …
“As Many as Possible for as Long as Possible”—A Case Study of a Soccer Team That Fosters Multiple Outcomes
2021
The personal assets framework suggests that dynamic elements of (a) personal engagement in activities, (b) quality social dynamics, and (c) appropriate settings will influence an athlete’s long-term outcomes of performance, personal development, and continued participation in sport. The aim of the present study was to conduct a case study of a Norwegian age-restricted team that was successful in promoting participation, performance, and positive development for individual participants and to investigate how the dynamic elements of activities, social dynamics, and settings have led to these long-term outcomes. The results indicated that the case is a best-practice example of successful attai…
Patología vascular: ¿causa o efecto en la enfermedad de Alzheimer?
2018
Resumen: Introducción: La enfermedad de Alzheimer (EA) es la principal enfermedad neurodegenerativa cortical. Su incidencia aumenta con la edad, lo que provoca importantes problemas médicos, sociales y económicos, especialmente en países con población envejecida. Objetivo: El objetivo de esta revisión es poner de manifiesto las evidencias que existen sobre el modo en que la disfunción vascular puede contribuir al deterioro cognitivo en la EA, así como las posibilidades terapéuticas que de ello podrían derivarse. Desarrollo: La hipótesis vascular ha surgido como alternativa a la hipótesis de la cascada amiloide como explicación de la fisiopatología de la EA. Esta hipótesis sitúa en los vasos…
La alteración de la mielina en la enfermedad de Alexander
2018
Resumen: Introducción: La enfermedad de Alexander (AxD) es una leucodistrofia. Su base patológica, junto a la pérdida de mielina, es la aparición de los cuerpos de Rosenthal, que son inclusiones citoplasmáticas en células astrocitarias. Mutaciones en el gen que codifica la GFAP se han identificado como una base genética para AxD. Sin embargo, no se conoce el mecanismo por el cual estas variantes producen la enfermedad. Desarrollo: La hipótesis más extendida es que AxD se desarrolla por un mecanismo por ganancia de función debido al incremento de GFAP. Sin embargo, este mecanismo no explica la pérdida mielínica, dado que los modelos experimentales que expresan GFAP normal o mutada no generan…
