Comparison of Classroom-Based Sedentary Time and Physical Activity in Conventional Classrooms and Open Learning Spaces Among Elementary School Studen…
2021
European children and adolescents spend most of their daily life and especially their school hours being sedentary which may increase their risk for chronic non-communicable diseases later in life. After the curriculum reform of Finnish basic education in 2014, most of the new or renovated comprehensive schools in Finland incorporate open and flexible classroom designs. Their open learning spaces may provide students opportunities to reduce sedentary behavior during school hours. Thus, waist-worn accelerometers were used to assess classroom-based sedentary time (ST), the number of breaks from sedentary time (BST), and physical activity (PA) among cross-sectional samples of 3rd and 5th grade…
Las formas cotidianas de la felicidad y sus mandatos: Pedagogías del pensamiento positivo, trabajo docente y subjetividad en el neoliberalismo contem…
2020
Positive thinking constitutes one of the great traditions that lead to the idea of the subject as an entrepreneur of himself and is perhaps one of the best that has successfully condensed cultural, political, social and pedagogical processes linked to reflection on well-being in this historical time. The teaching work is especially moved by the pregnancy of these perspectives that challenge the pedagogical field and the education workers as ?agents of change, or at least one more school available to give the discussion on well-being and happiness (yours and the students?) is celebrated and encouraged. In this article, I intend to understand what is being built as pedagogical discourses abou…
Structure ofD-ribonic acid-dimethyltin(IV) in coordinating solvents: an experimental and DFT119Sn NMR study
2006
We have investigated a newly synthesized complex of D-ribonic acid with dimethyltin(IV). The structure of the complex in solution has been characterized by means of 1 H, 13 C, and 119 Sn NMR and by DFT calculations. The comparison of experimental and computational results allowed the determination of the stable conformation in solution as well as the detection of a dimerization process. Moreover, evidence is given of active coordination of the metal by the solvent.
Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
The Influence of Contextual Aspects in Talent Development: Interaction Between Relative Age and Birthplace Effects in NBA-Drafted Players
2021
The aims of this study were two-fold: (1) to inspect separately for the relative age and birthplace effects for players selected in the National Basketball Association (NBA) draft; (2) to explore the interaction among these factors and analyse this interaction in players' career performance. The database was obtained from the official records of the players (n = 1,738), who were selected during the annual editions of the NBA Draft from 1990 to 2019. The participants' date of birth was analyzed according to the month of birth and divided into four quartiles. The place of birth was compared to the distribution of the general population' places of birth based on different communities' sizes. C…
I Symposium of Elite Performance in Combat Sports
2017
This report presents a summary of the I Symposium of Elite Performance in Combat Sports held in Madrid, May 27, 2017. The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Effects of training on bone metabolism in young athletes
2021
Purpose. This study investigated the effects of two types of training on the bone formation marker of osteocalcin and the bone resorption marker of tartrate-resistant acid phosphatase isoenzyme 5b (TRAP5b) in young track and field boys and girls. Methods. The 14-year-old group (10 boys, 10 girls) performed first time an intensive and supervised 8-week plyometric training. In the 17-year-old group (13 athletic boys, 6 control boys, 12 athletic girls, 6 control girls), the normal many-sided track and field training lasted 6 months. Results. Significant increases were noticed in osteocalcin (p < 0.01) both in younger boys and girls. The 20-m sprint performance improved in girls (p < 0.01) and …
AGE6. Skin Ageing: Focus on the Role of Inflammatory Genetic Factors in Cutaneous Neoplasia

AGE6. Skin Ageing: Focus on the Role of Inflammatory Genetic Factors in Cutaneous Neoplasia C. M. Gambino1, F. Crapanzano1, G. Accardi1, A. Aiello1, C. Virruso1, G. Pistone1, M. R. Bongiorno1, D. Lio1, C. R. Balistreri1, G. Candore1 1University of Palermo, Palermo, Italy Background: Skin aging is a complex process that involves intrinsic and exogenous causes. Photo-oxidative damage caused by UV is the leading cause of extrinsic aging of the skin, known as photo-ageing. UV damages can be linked mostly to overproduction of ROS that induces a complex molecular cascade able to accelerate physiological aging, determining a typical dermal/epidermal inflammation with an increased risk of getting s…
La calidad percibida de los servicios deportivos: diferencias según instalación, género, edad y tipo de usuario en servicios náuticos. (The perceptio…
2008
En el ambito de la gestion deportiva, la calidad de losservicios deportivos y la satisfaccion de los usuarios es un area de gran desarrollo. Este trabajo pretende determinar el grado de calidad percibida en unos servicios deportivos de caracter publico como son unas escuelas de actividades nauticas. Para ello se analizaron 2375 usuarios de estas escuelas que contestaron un cuestionario sobre calidad de servicio percibida y satisfaccion con el servicio recibido. La escala de calidad percibida utilizada determino diez dimensiones de calidad: las clases, el tiempo libre, el entorno nautico, los horarios, la comida, el material nautico, la comida complementaria, la conserjeria, la limpieza y la…
Effects of Rule Changes on Game-Related Statistics in Men's Water Polo Matches
2017
The aim of this study was to investigate the effects of rule changes on game-related statistics in men's water polo matches. A total of 856 men's matches played in all Olympic Games and World Championship since 1936 was analysed. The game-related statistics considered were: total goals, winners' goals, losers' goals, goals per minute, goals difference, relationship difference goals and total goals, and relationship difference goals and winners' goals. The rule changes were grouped by structural (game and period) and functional changes (possession time, exclusion time, timing, minimum distance to take a direct shot). Differences between rule changes were determined using a one-way ANOVA. In …
