«Was not the labour problem the same everywhere». «Homo ad laborem nascitur et avis ad volatum»! (Prolegomena per uno studio del diritto del lavoro t…
2019
The purpose of this research is to catalogue the biblical texts - notably in a first phase those which are in the first (or old) testament of the Christian Bible - which contain both prescriptive structures and pathways designed to protect the position of social weakness of the "worker", understood in its broadest sense and in its various and diverse facets: worker, salaried employee, servant, even slave, and so on. The starting point and most immediate objective of this work is therefore to find the biblical sources - and to get ready one first critical apparatus - which refer, directly or indirectly, to work in a broad sense, that is a personal relationship in which one of the two subject…
Physical activity, nutrition, and bone health
2018
This review aims to describe the roles that physical activity and nutrition have in bone metabolism and to examine their effects on bone in a situation of altered metabolism as a consequence of inadequate nutrition and/or excessive physical activity. Referring to the recent studies and the main guidelines in the literature on athlete nutrition, the paper also focuses on essential nutrients for bone health during performance. Finally, it discusses the negative effect of some nutrients on bone mineral density.
El sexo, el contexto familiar y la actividad física extraescolar como factores asociados a la coordinación motriz en la niñez. Un estudio piloto. [Ge…
2019
Existen diversos factores que determinan el desarrollo y la evolución de la coordinación motriz. El presente estudio tiene por objetivo analizar la influencia del sexo, la actividad física practicada por los padres, la existencia de hermanos/as mayores o de igual edad y la práctica de actividad física extraescolar sobre el nivel de coordinación motriz global. La muestra estuvo compuesta por 23 niñas y 32 niños de entre 8-9 años (M = 8,51; DT = 0,31), pertenecientes al tercer curso de Educación Primaria. El nivel de coordinación motriz global de los estudiantes se valoró a través del Test Motor GRAMI-2 (Ruiz, Rioja, Graupera, Palomo, y García, 2015). El análisis de regresión lineal múltiple …

Resultados: Por atletas, en el total de las carreras masculinas, la pierna de ataque predominante fue la izquierda con un 63,6 % (42 atletas) y con la pier…
Could Low-Frequency Electromyostimulation Training be an Effective Alternative to Endurance Training? An Overview in One Adult
2014
This preliminary study aimed to investigate the effects of a six-week low-frequency electromyostimulation training (10Hz) on the cardiovascular, respiratory and muscular systems. To that purpose, aerobic capacity, knee extensor muscles strength and architecture, muscle sympathetic nervous activity, blood pressure and heart rate have been evaluated in one healthy male subject (33 year-old, 1.73 m, 73 kg). Results showed improvement of aerobic capacity (+4.5% and +11.5% for maximal oxygen uptake and ventilatory threshold) and muscle strength (+11% and +16% for voluntary and evoked force). Moreover, for the first time, this study demonstrated low-frequency training effects on muscle architectu…
Intervención psicológica a distancia con un futbolista profesional: estudio de caso
2019
El objetivo del presente trabajo es estudiar las diferencias pre y post intervención psicológica online durante 9 meses en un joven jugador de fútbol profesional. Se parte de la demanda del deportista para mejorar su fortaleza mental y conseguir la titularidad en el equipo, ya que después de 2 meses de temporada, era suplente y se sentía "débil psicológicamente" para afrontarlo. Para ello, se evaluó al jugador con el CPRD, autorregistros y observaciones de partidos. La intervención se realizó por medio de videoconferencias, mensajería instantánea y correo electrónico. Principalmente, se aplicó técnicas cognitivo-conductuales, como la relajación, las autoinstrucciones, el planteamiento de cr…
Empathy in children practising judo compared to their non-practicing peers
2019
[EN] Many authors dealing with martial arts and combat sports indicate that this form of activity contributes to limiting aggressive behavior towards other people. Contemporary psychological and pedagogical knowledge explains that empathy is one of the factors that determines a friendly and aggression-free attitude of people towards others. This study we compared the level of empathy between children practicing judo for a minimum of two years and their peers who did not practiced any martial art. Results showed higher levels of empathy in the group of judo practitioners. Judo trainers also agreed that judo participation may improve children’s emotional development (emotional self-regulation…
Development of basic psychological need satisfaction in physical education
2019
Research shows that sports-active students experience more basic need satisfaction (autonomy, competence, relatedness) in physical education (PE) than their non-sports-active peers, and thus, reap most of the benefits of PE. This study aimed to investigate the role of a two-year PE programme, referred to as Interest-based PE, in contributing to students’ basic need satisfaction in PE, and in particular, to assess potential basic needs-benefits among students who were not involved in leisure-time sport. Among 693 students, 348 were offered a choice of two different PE approaches (“explorative” vs. “sports” approach) for the next two years, while the remaining students continued to receive tr…
Comparing the physical activity patterns of 3-year-old Finnish and Australian children during childcare and homecare days
2014
AbstractLimited previous research has contrasted physical activity (PA) patterns in preschool children across different hourly patterns or segments of day, or adopted similar methodologies to compare the PA behaviors of children from different countries. The purpose of this study was to examine how the PA levels and patterns differed between 3- year-olds within and between childcare and homecare days in Finland and Australia.ActiGraph GT3X accelerometers were used to monitor 121 (80 Finnish, 41 Australian) children’s PA for five consecutive days.No significant country differences were observed in children’s daily total PA (light-tovigorous PA [LMVPA]), except that during childcare days Finn…
Efectos de la vibración sobre la actividad del rectus abdominis y sobre la transmisión de aceleraciones durante la realización de un puente frontal. …
2012
Durante las dos ultimas decadas se ha incrementado notablemente la utilizacion de la vibracion como medio complementario de ejercicio fisico. La literatura cientifica muestra distintos efectos positivos, aunque la mayor parte de ensayos se han centrado en el analisis del ejercicio de squat. El objetivo del presente estudio fue analizar la actividad muscular del rectus abdominis y la transmision de la vibracion en el cuerpo humano durante la realizacion de un puente frontal sobre una plataforma vibratoria oscilante vibrando a diferentes frecuencias (5, 16, 20 Hz) y a una amplitud constante (3 mm). Las aceleraciones maximas en la cabeza (ejes X, Y, Z) y la actividad electromiografica media de…
