Effect of mountain ultramarathon distance competition on biochemical variables, respiratory and lower-limb fatigue
2020
The study aimed at assessing the acute physiological effects of running a 65-km vs a 107- km mountain ultramarathon. Nineteen athletes (15 males and 4 females) from the shorter race and forty three athletes (26 males and 17 females) from the longer race were enrolled. Body weight, respiratory and lower limb strength were assessed before and after the race. Blood samples were obtained before, after and 24-h post-race. Body weight loss did not differ between races. A decrease in squat jump height (p<0.01; d = 1.4), forced vital capacity (p<0.01; d = 0.5), forced expiratory volume in 1 s (p<0.01; d = 0.6), peak inspiratory flow (p<0.01; d = 0.6) and maximal inspiratory pressure (p<0.01; d = 0.…
Gender, self-confidence, sports, and preferences for competition
2016
In the last years, research in economics has shown a gender gap in the willingness to compete with women shying away from competition more than men do. This gender difference in preferences towards competition has been considered a critical factor in explaining the small percentage of women found in top-level positions in business, science, or politics. Therefore, in order to improve women job prospects, research and policy interventions try to offer incentives for women to increase competitive behavior. However, other recent studies specifically point at men¿s competitive behavior as the responsible for some of the financial markets malfunctions, suggesting that an influx of talented women…

En estas últimas décadas la gestión de las actividades relacionadas con el deporte ha tomado un papel relevante para las instituciones deportivas. La matemática borrosa, aporta un conjunto de algoritmos que permiten establecer la idoneidad del deportista, el cual ha de reunir ciertas cualidades que lo hagan adecuado para la posición o posiciones que debe ocupar en un determinado equipo. Bajo estos preceptos, hay que resaltar que la Teoría de Conjuntos Borrosos no es un segmento de la Matemática emergente en nuestros días si no que, tiene sus inicios en la década de los años 20, siendo en la de los 50, donde sentó sus bases.
Relationship between muscular extensibility, strength and stability and the transmission of impacts during fatigued running
2020
The aim was to analyse the relationship between isokinetic strength, dynamic stability, muscular extensibility and impacts transmission during fatigued running. Low- and high-frequency impacts related to body movements and the severity of impacts, respectively were assessed in 17 male recreational runners, before and after a treadmill running fatigue protocol, using a triaxial accelerometry system. High-frequency impacts in the tibia were negatively correlated to the knee angle at which the quadriceps peak torque was reached (p = 0.014), and also to the extensibility of the hamstrings and soleus (p = 0.001 and p = 0.023, respectively). The increases of high-frequency impacts in tibia caused…
A Mixed Methods Study to Examine the Influence of CLIL on Physical Education Lessons: Analysis of Social Interactions and Physical Activity Levels
2020
Physical Education is often selected for applying multilingual initiatives through the use of a content and language integrated learning (CLIL) approach. However, it is still unclear whether the introduction of such an approach might entail losing the essence of physical education and distorting its basic purposes. The aim of this study is to analyze the impact of CLIL on physical education lessons. Given the purpose of this study, a mixed methodological approach based on a sequential exploratory design divided into two different phases is used. We begin with initial qualitative data collection (phase I), consisting of the analysis of interviews with 12 participants (8 teachers and 4 studen…
Psychometric properties of the interaction on supervised classes scale (ISCS)
2016
Objeto: La presente investigación se centra en la construcción y validación de una escala diseñada para evaluar la calidad de la clases dirigidas: Escala de Interacción en las Clases Dirigidas (EICD). Diseño/metodología/enfoque: Se trata de un estudio descriptivo correlacional. Para la elaboración de la escala se recurrió a tres fases diferenciadas en las que diferentes expertos evaluaron la adecuación de los ítems, finalmente se estudiaron las propiedades psicométricas de la versión final en una muestra de 314 socios (69.1% mujeres) con edades entre los 18 y los 77 con una media de 39.33 años (DT=12.25). Aportaciones y resultados: La escala presenta una validez y fiabilidad adecuadas, sien…
Ultrasound Imaging Evaluation of Textural Features in Athletes with Soleus Pathology—A Novel Case-Control Study
2021
Background: the aim of this study was to compare the echotexture of patients with soleus muscle injury and age matched controls. Methods: a sample of 62 athletes was recruited at the private clinic and was divided in two group: a healthy group (n=31) and a soleus pathology group whose athletes had soleus muscle injury, located in the central tendon (n=31). The muscle thickness (MTh), echointensity (EI) and echovariation (EV) were analyzed. An intra-rater reliability test (Intraclass Correlation Coefficient-ICC) was performed in order to analyze the reliability of the values of the measurements. Results: Sociodemographic variables did not show statistically significant differences (p >
Effect of the upper material of running shoes on muscle mechanical power transfer on lower limbs
2022
This study focuses on determining the effects of the upper material of running shoes on the mechanical power flows of the muscles of the lower limbs during the support phase of running. Two models of running shoes—differentiated only by the upper structure and material—have been used, being randomly assigned to 19 participants. Five measurements of each participant per shoe model were obtained at 3.3 m·s−1 to perform inverse dynamic analysis with the data obtained. Statistically significant differences have been found between the two models for the muscle power flow variables in the ankle, knee and hip joints, as well as at the ends of adjacent segments. The KNIT-upper model (model 2) pres…
Inteligencia emocional y características psicológicas relevantes en mujeres futbolistas profesionales
2023
Resumen La Inteligencia Emocional es la capacidad de reconocer, entender, controlar y modificar nuestras emociones y las de los demás. El objetivo de este estudio fue determinar si la variable Inteligencia Emocional se relaciona con aquellas variables psicológicas relevantes para el rendimiento deportivo. Las participantes fueron 60 jugadoras de fútbol de 13 equipos de primera división 'Liga Iberdrola', con una media de edad de 24,33±3,72. Se utilizó el Cuestionario de Características Psicológicas relacionadas con el Rendimiento Deportivo (CPRD) y la Escala Rasgo de Metaconocimientos sobre Estados Emocionales (TMMS-24) para evaluar las variables de estudio. Los resultados indican que la Int…
Coaches as promoters of team cohesion
2015
El objetivo del presente trabajo fue triple: 1) Estudiar las relaciones entre el clima motivacional percibido creado por el entrenador y la cohesión, 2) Poner a prueba un modelo con la siguiente secuencia: dimensiones del clima motivacional percibido motivación autodeterminada dimensiones de la cohesión, y 3) Estudiar el papel mediador de la motivación autodeterminada entre el clima motivacional percibido y la cohesión. Ochocientos nueve jóvenes jugadores de fútbol (798 chicos y 11 chicas; M = 11.49, DT = 1.16) completaron un paquete de cuestionarios en los que se evaluaban las variables de interés al principio de la temporada. Las correlaciones bivariadas informaron de relaciones posit…
