Physical activity using social media during the COVID-19 pandemic: the perceptions of sports science students
2021
Abstract During the period of the COVID-19 lockdown, sports organizations and companies had to look for new ways to connect with their customers by offering physical activity (PA) alternatives to do at home. This study explores the perceptions of 175 undergraduate sports science students regarding their social media (SM) and PA patterns during the first Spanish COVID-19 lockdown period (March to May 2020). From their homes, the students completed an ad hoc online questionnaire. The data was analyzed using SPSS 23.0 software to perform descriptive and inferential analysis (t-test). The results show that the participants used SM during the COVID-19 lockdown to visualize or practice PA, percei…
Impact of Sport-related Games on High School Students' Communication Skills
2015
Abstract In Recent studies underline the fact that adolescents are, at many times, likely to experience serious communication problems with their families and close environments. So, the aim of this study is to determine positive impact of sport-related games, which are performed as extracurricular activities, on high school students’ communication skills. In the study, pre, & post-tests was utilized with the control group’s experimental patterns. Two participant groups were made up of totally 30 high school students, 15 of whom would be in the experimental group and the rest of whom were in the control group. The former group was given sport- related 20 applications for 10 weeks during…
The Sport for All Ideal: A Tool for Enhancing Human Capabilities and Dignity
2014
Abstract Sport, as a child of modernity, is intertwined with typically modern elements, such as the search for universality, competition, and the fascination for measurement. As modernity is essentially defined, in legal and moral terms, as a search for universally grounded moral principles or basic human rights, modern sports are widely seen as a means to promote typically modern values such as dignity. This paper conceives of the term "dignity" in light of the capabilities approach upheld by Martha Nussbaum and Amartya Sen. According to these authors, dignity is conferred according to certain human basic capabilities that we all are entitled to. This is the reason why this article explore…
A Hermeneutical Analysis of the InternalistApproachin the Philosophy of Sport
2015
Abstract In this paper, we make a hermeneutical analysis of internalism, the dominant tradition in the philosophy of sports. In order to accomplish this, we identify the prejudices that guide the internalist view of sports, namely the Platonic-Analytic prejudice introduced by Suits, one of the forefathers of internalism. Then, we critically analyze four consequences of following such a prejudice: a) its reductive nature, b) the production of a unrealistic view of sports, c) the vagueness of the idea of excellence; and d) the leap from the descriptive analysis of the sporting phenomenon to the setting of normative requirements for the practice of sports.
Evaluación de un programa de actividad física en adultos mayores no institucionalizados
2021
La actividad física es uno de los hábitos clave que influyen en el envejecimiento saludable, según la OMS. El objetivo de este estudio fue evaluar el efecto en la esfera funcional de un programa de actividad física realizado en el contexto de un taller de envejecimiento activo. Se realizó un estudio de diseño de preintervención y posintervención en un solo grupo. Se incluyeron 54 adultos sanos, no institucionalizados, de edad igual o mayor a 60 años. El programa de actividad física consistió en 90 sesiones grupales bisemanales, de 45-60 minutos de duración, realizadas durante 45 semanas. Los participantes realizaron estiramientos y ejercicios aeróbicos y de tonificación muscular de intensid…
Formación del profesorado de educación física en el uso de aplicaciones tecnológicas
2021
La inclusión de las Tecnologías de la Información y Comunicación (TIC) en el ámbito educativo precisa de un profesorado con un nivel de competencia digital (CD) suficiente para enseñar al alumnado dicha tecnología. Paradójicamente, en la literatura existe una tendencia emergente por el estudio de la CD, mientras que el uso específico de las herramientas tecnológicas se está dejando de lado, especialmente en el campo de la educación física (EF). Por ello, el objetivo del presente trabajo fue valorar el empleo real de las aplicaciones educativas por parte del futuro profesorado de EF. Para ello, se aplicó el cuestionario CUTDEF (Cuestionario sobre conocimiento y uso de las TIC por los y las d…
Contents of Physical Education through the Images of PrimaryEducation Textbooks
2014
Esta investigación analiza las imágenes relacionadas con las actividades físicas que aparecen en los libros de texto de educación física (EF), concretamente en el tercer ciclo de la etapa de educación primaria (EP) y su correspondencia con los bloques de contenido de dicho currículo. La muestra está formada por 821 imágenes publicadas en cuatro editoriales españolas, a partir de la LOE. Se realiza un estudio descriptivo univariante mediante un sistema de categorías elaborado ad hoc, cuyo proceso de construcción consta de dos pruebas piloto, dos consultas a expertos y la triangulación con tres observadores. Las variables del estudio son: tipo de actividad física, ámbito, espacio y nivel de p…
Preparation and structural studies on diorganotin(IV) complexes of N-nitroso-N-phenylhydroxylaminates
2007
Abstract Diorganotin(IV)-complexes of the N -nitroso- N -phenylhydroxylaminates (hereinafter cupf), Et 2 Sn(cupf) 2 ( 1 ), Bu 2 Sn(cupf) 2 ( 2 ), {[Bu 2 Sn(cupf)] 2 O} 2 ( 3 ), t -Bu 2 Sn(cupf) 2 ( 4 ) and Oc 2 Sn(cupf) 2 ( 5 , 6 ) were prepared and characterised by FT-IR and Mossbauer spectroscopic measurements. The binding modes of the ligand were identified by FT-IR spectroscopy, and it was found that the ligand is coordinated in chelating or bridging mode to the organotin(IV) center. The 119 Sn Mossbauer and FT-IR studies support the formation of trans -O h ( 1 – 6 ) structures. The X-ray diffraction analysis of 4 revealed that the tin centre is in a skew-trapezoidal geometry defined by…
CH4 oxidation in a boreal lake during the development of hypolimnetic hypoxia
2020
AbstractFreshwater ecosystems represent a significant natural source of methane (CH4). CH4 produced through anaerobic decomposition of organic matter (OM) in lake sediment and water column can be either oxidized to carbon dioxide (CO2) by methanotrophic microbes or emitted to the atmosphere. While the role of CH4 oxidation as a CH4 sink is widely accepted, neither the magnitude nor the drivers behind CH4 oxidation are well constrained. In this study, we aimed to gain more specific insight into CH4 oxidation in the water column of a seasonally stratified, typical boreal lake, particularly under hypoxic conditions. We used 13CH4 incubations to determine the active CH4 oxidation sites and the …
Study of postural control and body balance in subjects with Down syndrome
2020
Purpose. Body imbalance and poor postural control have negative impact on gait and may increase the risk of falling in healthy individuals as well as those with Down syndrome (DS). Since people with DS have lower physical levels than people who do not present this condition, the purpose of our research was to compare features of postural control and body balance between subjects affected by DS and a control sample. Methods. Participants enrolled were divided into the following two groups: A DS group (DSG; n = 22; 9 females and 13 males; age range: 16-36 years) and an age-matched control group (CG; n = 25; 11 females and 14 males; age range: 16-36 years). All participants were subjected to t…
