Validación de una ficha de observación para el análisis de habilidades socio-emocionales en Educación Física (Validation of an observation instrument…

2016

Ante la necesidad de dotar a los docentes de Educación Física de herramientas que les permitan valorar con rigor el resultado de su trabajo en el ámbito socio-emocional, el presente trabajo expone el proceso de diseño y validación de un sistema de categorías para valorar las habilidades socio-emocionales de alumnado de primer ciclo de educación primaria de Educación Física, a través de la observación en situaciones de juego motor. Los resultados obtenidos tras el análisis lógico y empírico de los datos ponen de manifiesto la fiabilidad y estabilidad de las categorías propuestas. Además, se muestra todo el proceso como ejemplo para la elaboración de instrumentos de observación que sean útile…

Random vibration mitigation of beams via tuned mass dampers with spring inertia effects

2019

The dynamics of beams equipped with tuned mass dampers is of considerable interest in engineering applications. Here, the purpose is to introduce a comprehensive framework to address the stochastic response of the system under stationary and non-stationary loads, considering inertia effects along the spring of every tuned mass damper applied to the beam. For this, the key step is to show that a tuned mass damper with spring inertia effects can be reverted to an equivalent external support, whose reaction force on the beam depends only on the deflection of the attachment point. On this basis, a generalized function approach provides closed analytical expressions for frequency and impulse res…

Effectiveness of a creative physical education intervention on elementary school students’ leisure-time physical activity motivation and overall phys…

2018

This study investigated the effectiveness of a creative physical education (CPE) intervention on students’ perceptions of motivational climate in physical education (PE), leisure-time physical activity (PA) motivation, and overall PA. A sample of 382 fourth to sixth grade students ( Mage= 10.87[.93]) from two elementary schools were assigned to the CPE intervention ( n = 196; Mage= 10.84[.95]) and control ‘PE-as-usual’ ( n = 186; Mage= 10.90[.90]) groups. Students’ perceived task- and ego-supportive climate in PE, leisure-time PA motivation, and overall PA were measured before and after the one-year intervention. Analyses of covariance and path analyses were implemented to test the effectiv…

The importance of coaches' autonomy support in the leisure experience and well-being of young footballers

2018

Drawing on the self-determination framework, the study examined the effect of coaches' autonomy support on the leisure experience of young male football players. Specifically, a model was tested analyzing the long-term predictive power of the players' perceptions of the coaches' autonomy support at the beginning of the season on the subjective vitality of young football players at the end of the season, through needs satisfaction and intrinsic motivation (IM). Moreover, we tested whether the effects of coaches' autonomy support on the aforementioned variables (needs satisfaction, IM, and subjective vitality) at the end of the season remained at the beginning of the following season. Because…

Water polo game-related statistics in women’s international championships as a function of final score differences

2016

The aims of this study were: (i) to compare water polo game-related statistics by context (winning and losing teams) and final score differences (using three categories – “close” games, “unbalanced...

Ten Years’ Experience with an E-Learning Lecture Series on Cancer Biology and Pharmacology

2013

In life sciences, the internet is an indispensable medium for research, but has not yet realized its full potential for teaching. The concept of e-learning has been developed over the past decades for undergraduate, graduate and postgraduate programs. We set up an e-learning lecture on cancer biology and pharmacology that was first offered in 2003 to students of Molecular Biotechnology at the University of Heidelberg and to students of Pharmacy at the University of Mainz, Germany. The present paper recapitulates the first decade of experiences with this e-learning lecture from both the students’ and the teachers’ perspectives. A total of 317 students during the past 10 years participated in…

HEMATOLOGICAL VARIABILITY ANALYSIS AFTER ROAD MARATHON VS ULTRATRAIL. PREDICTIVE FACTORS

2020

The practice of long- and medium-distance races has exponentially increased the number of participants in recent years. They are carried out under extreme conditions that cause both biochemical and anthropometric changes in athletes and, in addition, have serious risks associated, such as dehydration, thermal disorders, or hypoglycemia. Knowledge regarding alterations at hematological level after this type of effort is limited. The objectives of this pre-post analytical descriptive observational study were: to describe and compare hematological values in amateur runners pre and post road marathon and ultratrail races, and to compare the hematological parameters between the groups in the two…

Autogreffe chondrocostale pour lésion latérale ostéochondrale de la tête métacarpienne

2020

Abstract Osteochondral injuries of the metacarpal head require anatomical restoration to prevent limitations in range of motion and osteoarthritis. Osteochondral bone grafting is a viable option, especially in younger patients. Central injuries allow for different types of grafting, but when the injured area is on the lateral portion of the metacarpal head, the graft must include both a cortical and a cartilaginous portion. We present here the pearls and pitfalls in the surgical technique of chondrocostal grating from the 6th rib and an example of its use within a case of comminuted fracture of the metacarpal head. This technique provides a graft with cortical bone that allows for a stable …

Effectiveness of physical activity promoting technology-based distance interventions compared to usual care. Systematic review, meta-analysis and met…

2017

Introduction Technology has been thought to have strong potential for promoting physical activity, but the evidence has remained unclear. The aim of this study was to examine whether a technology-based distance intervention promoting physical activity is more effective than a physical activity intervention without the use of technology. This systematic review is registered in Prospero (CRD42016035831). Evidence acquisition A systematic literature search of studies published between January 2000 to December 2015 was conducted in CENTRAL, EMBASE, Ovid MEDLINE, CINAHL, PsycINFO, OT-Seeker, WOS and PEDro. Studies were selected by two independent authors applying the following PICOS criteria P) …
