2014
[ES] El desarrollo de escalas de autoeficacia permite el análisis de las percepciones de los deportistas y el examen de la relación entre dichas percepciones y el rendimiento. El objetivo de este estudio fue (1) desarrollar una escala específica de autoeficacia para una tarea de taekwondo, la patada circular, y (2) analizar el rendimiento deportivo y su relación con los resultados de dos escalas de autoeficacia (específica y general) en función del género de los deportistas. En el estudio participaron 43 taekwondistas (33 hombres y 10 mujeres). Se administraron las escalas de autoeficacia Física (PSE) y Específica (RKSES). Los datos de rendimiento (fuerza de impacto y tiempo total de respue…
Influencia de la satisfacción y el valor percibido sobre el “Word of Mouth” en los usuarios de centros deportivos
2019
Uno de los principales objetivos de los servicios deportivos, es fidelizar a los usuarios el mayor tiempo posible en dicho servicio. Por ello, desde el inicio de la literatura de la gestión del deporte, que analizan las diferentes variables de gestión, cada vez más, aparecen trabajos que tratan de aportar información relacionada con este objetivo. Dentro de las inten- ciones futuras de los usuarios, la recomendación es uno de los factores claves para poder analizar los futuros comportamientos de dichos usuarios. Por ello este trabajo, trata de analizar cuál es la influencia de la satisfacción y el valor percibido de los usuarios, sobre el “Word of Mouth” (boca-oído), es decir, como influyen…
Revistas iberoamericanas de Educación Física/Ciencias del Deporte presentes en Web of Science: evaluación y desafíos
2014
ResumenEn este artículo se evalúan varias dimensiones estratégicas de ocho revistas iberoamericanas de Educación Física/Ciencias del Deporte (cinco brasileñas, dos españolas y una portuguesa) presentes en la nueva plataforma Web of Science. Con ello se pretende reflexionar sobre los desafíos próximos a los que deben enfrentarse y también ser útil en la mejora de la calidad de estas publicaciones. El análisis se realizó sobre los fascículos editados en 2012 y a partir de la información disponible en sus versiones electrónicas. Los resultados muestran que, en general, la transparencia y la gestión del proceso editorial son mejorables y que la internacionalización y la visibilidad de las revis…
Influence of Training Load on Mood Disturbance at Sea Level and 3900 m Altitude: A Case Study of a Wheelchair Athlete
2018
The purpose of this case study was to investigate the influence of a training load (TL), oxygen saturation (SO2) and blood pressure (BP) on mood states in a wheelchair marathoner during (7 weeks at sea level (SL), 5 weeks at 3860 m altitude, 1 week returning to SL). TL was obtained with Foster’s equation while mood states were obtained with the Profile of Mood States Questionnaire (POMS). Furthermore, SO2 and BP were assessed upon wakening. SO2 (%) decreased at altitude, compared to SL (88.31 ± 2.46 vs. 98.52 ± 0.11) and increased until the last week at altitude (92.64 ± 1.12). Systolic pressure (SP) increased at altitude compared to pre-altitude (126.0 ± 5…
Intervención Psicológica en un jugador de pádel competitivo: un estudio de caso

Para la medición previa y posterior a la intervención se utilizó el CPRD y dos instrumentos ad hoc sobre variables psicológicas e ideas potenciadoras en el deporte. Durante la intervención se utilizaron las estrategias psicológicas de establecimiento de objetivos, parada de pensamiento, autorregistro de ideas potenciadoras, rutinas …
Development of a Novel Object Detection System Based on Synthetic Data Generated from Unreal Game Engine
2022
This paper presents a novel approach to training a real-world object detection system based on synthetic data utilizing state-of-the-art technologies. Training an object detection system can be challenging and time-consuming as machine learning requires substantial volumes of training data with associated metadata. Synthetic data can solve this by providing unlimited desired training data with automatic generation. However, the main challenge is creating a balanced dataset that closes the reality gap and generalizes well when deployed in the real world. A state-of-the-art game engine, Unreal Engine 4, was used to approach the challenge of generating a photorealistic dataset for deep learnin…

2020
Highlights • Low levels of physical activity are a risk factor associated with Alzheimer's disease. • Older adults who exercise are more likely to maintain cognition. • Exercise modulates amyloid β turnover, inflammation, synthesis, and release of neurotrophins, and cerebral blood flow.
Childhood Sports Participation Is Associated With Health-Related Quality of Life in Young Men: A Retrospective Cross-Sectional Study
2021
The aim of the study was to examine whether sports participation (SP), engagement in competitive sports (CS) and the type of sport undertaken at the age of 12 are associated with the physical and the mental components of health-related quality of life (HRQoL) in young adulthood. The data were collected using questionnaires prior to a compulsory military refresher training course in Finland. The sample consisted of 784 men (mean age 26 years). HRQoL was measured with RAND 36 and childhood sports participation with a series of questions. Data were analysed with logistic regression. Higher frequency of SP, participation in district level CS, performing team, endurance or extreme sports and pla…
Organized Sport Participation and Physical Activity Levels among Adolescents with Functional Limitations
2017
Sufficient and regular physical activity is considered a protective factor, reducing the onset of secondary disability conditions in adolescents with chronic diseases and functional limitations. The aim of this study was to explore whether participation in organized sport may be associated to higher levels of physical activity in adolescents with functional limitations, based on a national representative sample. Data from the Health Behaviour in School-aged Children (HBSC) study collected in Finland from two data collection rounds (2002 and 2010) were conducted and pooled from adolescents aged between 13 and 15 years old with functional limitations (n = 1041). Differences in self-reported p…
Physical fitness of individuals with intellectual disability who have special olympics experience
2016
Physical fitness of individuals with intellectual disability (ID) is low compared to those without ID. Part of the mission of Special Olympics is to develop physical fitness. However, little is known about fitness levels of Special Olympics athletes. This study examined the fitness level of individuals who participated in Nordic Special Olympics Games 2008 in Finland. The sample consisted of 59 Special Olympics athletes (44 men, 15 women, age 16–45) whose fitness scores were compared to INAS-athletes (International Association of Sport for para-athletes with ID) and Finnish non-athletic individuals with ID. The fitness battery consisted of 8 items: BMI, sit-and-reach test, stork stand, sit …
