ABSTRACT The study investigated associations between selected physical activity correlates among 299 adolescents (90 boys, age 12-14 years) from 3 English schools. Physical activity was assessed by self-report and accelerometry. Correlates represented biological, predisposing, and demographic factors as described in the Youth Physical Activity Promotion Model. Boys engaged in more self-reported (p < .01) and accelerometer assessed physical activity than girls (p = .02). Positive associations between sex (male), BMI, Perceived PE Ability, Perceived PE Worth, number of enrolled students, and physical activity outcomes were evident (p < .05). School-based physical activity promotion should emphasize sex-specific enhancement of students' perceived PE competence and enjoyment.

    • "Por tanto, el docente de EF, como antecedente social de la TAD, puede ser una detonante clave a la hora de adherir al alumnado a la práctica de AF, apoyando sus necesidades psicológicas básicas, para conseguir que perciba que la EF merece la pena (Belton, Wesley, Meegan, Woods & Issartel, 2014). Este hecho es especialmente relevante ya que el desarrollo de una mayor actitud afectiva y cognitiva hacia la AF se considera una tarea prioritaria para favorecer estilos de vidas más activos en el alumnado (Hilland, Ridgers, Stratton & Fairclough, 2011). De este modo, tomando como sustento la TAD (Ryan & Deci, 2007) y el modelo de promoción de la AF (Welk, 1999), y ante la ausencia de investigaciones que muestren la sinergia entre la percepción de apoyo a las necesidades psicológicas básicas (i.e., autonomía, competencia y relaciones sociales) y la predisposición hacia el contenido del alumnado (i.e., actitud cognitiva y afectiva) a nivel situacional, se estableció como objetivo principal analizar la asociación entre estas dos variables de estudio, en diferentes unidades didácticas (UD).

    ABSTRACT: Resumen: Siguiendo la teoría de la autodeterminación, el objetivo de este estudio fue analizar la asociación entre la percepción de apoyo a las necesidades psicológicas básicas (i.e., autonomía, competencia y relaciones sociales) y la predisposición hacia el contenido (i.e., actitud cognitiva y afectiva) que tiene el alumnado. El estudio fue desarrollado en tres unidades didácticas de Educación Física, donde participaron 77 alumnos en el contenido de fútbol sala, 75 en acrosport y 78 en rugby, pertenecientes a 4º de Educación Secundaria Obligatoria. Los resultados de los análisis de correlación y los análisis predictivos señalan una relación positiva entre la percepción del apoyo de las tres necesidades psicológicas y la predisposición hacia el contenido que tienen los alumnos, adquiriendo uno u otro mediador más importancia en función del contenido curricular impartido. En base a ello, se destaca la importancia de apoyar las tres necesidades psicológicas básicas mediante estrategias de intervención que deben ser diseñadas y adaptadas para cada contenido curricular. Todo ello puede redundar en una mayor predisposición del alumnado hacia cada uno de los contenidos curriculares que integran la Educación Física, suponiendo una mayor adherencia hacia la práctica de actividad física. Palabras clave: actitud cognitiva; actitud afectiva; teoría de la autodeterminación; adolescentes. Abstract: Grounded in the self-determination theory, the aim of the study was to analyze the association between perceived support of basic psychological needs (i.e., autonomy, competence and relatedness) and predisposition toward the content (i.e., cognitive and affective attitude). The study was developed in three Physical Education teaching units. The sample was comprised of 77 football, 75 acrosport and 78 rugby 4 th-year compulsory Secondary Education students. The results of the correlation and predictive analysis indicate a positive relationship between perceived support of the three psychological needs and predisposition to the content. The importance of each psychological need was different depending on the teaching unit. The usefulness of supporting the three basic psychological needs through intervention strategies was highlighted. These strategies should be designed and adapted for any curricular content. This can result in a greater predisposition of students to each of the units that integrate Physical Education. It can also lead to greater adherence to participation in physical activity.

    • "The majority of these studies have used observations or selfreported measurements when studying the association between schoolyard characteristics and children's movement patterns (Hilland et al., 2011; Ridgers et al., 2010; Taylor et al., 2011). Only few studies used objective measures (Global positioning systems (GPS) in combination with heart rate monitor), in assessing the movement patterns and PA levels of children aged 6 and 14 years old in one recess (Fjortoft et al., 2009, 2010).

    ABSTRACT: Physical activity (PA) in childhood is related to a multitude of short- and long-term health consequences. School recess can contribute with up to 40% of the recommended 60 min of daily moderate-to-vigorous physical activity (MVPA). This paper aims to investigate how schoolchildren use different schoolyard areas during recess and whether these areas are associated with different levels of PA. Time spent by 316 students (grade 5–8) in five types of schoolyard area was measured during at least two days and four separate recess period per person (in total 1784 recess periods), using global positioning system (GPS) and the level of activity was measured using accelerometers. Total time spent and proportions of time spent sedentary and in MVPA were calculated per area type. Significant differences in PA levels were found. Grass and playground areas had the highest proportion of time in MVPA and solid surface areas had the highest proportion of time spent sedentary. Boys and children spent a higher proportion of time in MVPA. Girls accumulated more sedentary time in all area types compared to boys. This finding emphasizes the importance of investigating various settings and features in schoolyards in promoting PA. Grass and playground areas may play an important role in promoting PA in schoolyards, while a high proportion of time in solid surface areas is spent sedentary. In future, more detailed studies of the exact schoolyard setting using a combination of GPS, accelerometer and direct observation would be beneficial.

    ABSTRACT: Around 7.8 million people in the UK are affected by chronic pain, which can have devastating effects on their and their families' quality of life. Studies suggest that children may show lower than average social skills and higher levels of pain complaints, whilst partnerships show a lack of intimacy and social interaction as argued by Snelling (1994), Evans et al (2007), Ireland and Pakeham (2010) and Closs et al (2009). Families experience disruption to their everyday life through role shifting within the family unit, financial difficulties, exhaustion, resentment, helplessness and lack of communication and understanding (Roy, 1992). However, conventional treatment routes are limited and often only available to patients themselves excluding family members leaving them to cope with a dis-located family life on their own. My research addresses these issues within those families. I suggest it may be improved through the help of imagery, similar to the methods which have been used successfully for the treatment of phantom limb pain and most recently in patients with chronic facial pain at London’s University College Hospital (Padfield, Zakrzewska, 2011a). I suggest that some of these feelings may be eased by photography depicting all of those emotions, sharing the experiences without the need of words. In conclusion, I am proposing to create a body of photographic images by translating this sheaf of emotions into pictures which may provide sufferers and their families with a tool to improve understanding, communication and ultimately family life.
