“…Six (32)(33)(34)(35)(36)(37) cross-sectional studies were identified including between 398 and 20 871 participants. All studies assessed physical activity by accelerometry and outcome measures were BMI, BMI z-score, waist circumference and body composition (e.g.…”

“…However, recently this assumption has been challenged and some have suggested that physical activity at baseline is unrelated to weight gain at follow-up, but that the converse was true, since greater adiposity levels at baseline was significantly related to lower levels of physical activity or an increased risk of becoming sedentary at follow-up, suggesting reverse causality (35,51,52) . Kwon et al (51) examined the associations between objectively measured time in MVPA by accelerometry, with gain in fat mass in 326 US children, in which objectively measured physical activity and fat mass was available at three time points.…”

High amounts of time spent sedentary and low levels of physical activity have been implicated in the process of excessive adiposity gains in youth. The aim of this review is to discuss the role of physical activity, sedentary time and behaviour (i.e. television (TV)-viewing) in relation to adiposity during the first two decades of life with a specific focus on whether the association between sedentary time, and behaviour and adiposity is independent of physical activity. We identified nine cohort studies (three prospective) whether sedentary time was associated with adiposity independent of physical activity. Eight of these studies suggested that sedentary time was unrelated to adiposity when physical activity was taken into account. Results from studies (n 8) examining the independent association between TV-viewing and adiposity independent of physical activity were mixed. Those that observed a positive association between TV-viewing and adiposity independent of physical activity discussed that the association may be due to residual confounding. A few additional studies have also challenged the general notion that low levels of physical activity leads to fatness and suggested that higher baseline fatness may be predictive of a decline in physical activity. It appears unlikely that higher levels of sedentary time are associated with or predictive of, higher levels of adiposity when physical activity is controlled for in youth. Specific sedentary behaviours such as TV-viewing may be associated with adiposity independent of physical activity but the results may be explained by residual confounding. Adolescents: Children: Obesity: Physical activity: Sedentary behaviourGlobal data suggest that overweight and obesity affects almost every nation and every age group in the world with an almost doubling of obesity rates during the last 20 years (1) . The obesity epidemic also affects infants, children and adolescents. Despite some recent reports suggesting a levelling off of the prevalence of overweight and obesity in young people (2,3) , childhood obesity rates have reached alarming proportions even in developing countries (4) . Obesity is multifactorial including genetic, pre-and post-natal factors, physiological, cultural, environmental, lifestyle and socio-economic factors, possibly acting differentially on the development of unhealthy weight gain and obesity throughout the life course. The main contributor to the recent obesity epidemic is most likely an imbalance between energy intake and energy expenditure. Physical activity is the most variable component of total energy expenditure and recent reports suggest that approximately 30-40 % of young people are physically active according to public health recommendations when assessed by selfreport (5,6) . However, studies using direct measures of physical activity by accelerometry are extremely divergent with prevalence values for sufficiently active young people varying between 1 and 100 % depending on the definition of moderate-and vigorous-intensity physical activi...

“…Cada vez son más los investigadores que tratan de paliar los riesgos psicosociales asociados al ámbito laboral apoyándose en los trabajos científicos existentes que relacionan la práctica de actividad física con la salud física, mental y social (Ekelund et al, 2012) y la calidad de vida (Martínez & Calvo, 2014). Entre las diferentes opciones de práctica físico-deportiva, el método Pilates ha irrumpido con fuerza en nuestra sociedad (Boix, León, & Serrano, 2014) y es practicado por millones de personas en todo el mundo (Chang, 2000;Muirhead, 2004).…”

ResumenLos efectos de la práctica del método Pilates sobre la salud psicosocial y laboral carecen de evidencia científi-ca sólida. El objetivo principal del presente estudio fue describir los niveles de salud psicosocial de un grupo de trabajadores que se ejercitaba con la técnica Pilates. También se estudió la influencia del cargo laboral sobre variables psicosociales. 63 trabajadores de diferentes profesiones del sector servicios con una jornada laboral completa (47 mujeres y 16 hombres) participaron; de ellos 33 ya asistían a clases de Pilates una media semanal de 2.82 días y el resto de participantes no realizaba ninguna actividad físico-deportiva (sedentarios). Los resultados mostraron que el grupo Pilates registraba mayores niveles de estabilidad emocional y optimismo que el grupo sedentario en la medición 1. Además, se ha podido observar que, entre los practicantes de Pilates, los dirigentes presentan mayor control en el trabajo y sintomatología depresiva y menor estabilidad emocional que los empleados en ambas mediciones. En definitiva, pese a los numerosos beneficios que se le atribuyen a la práctica Pilates y el creciente interés existente entre los investigadores por analizar sus efectos sobre la salud, el presente estudio evidencia la ausencia de importantes diferencias en la salud psicosocial y laboral tras seis meses de seguimiento.Palabras clave: Método Pilates, burnout, tensión laboral, optimismo, trabajo. AbstractThe effects of practice of Pilates on psychosocial and occupational health, lack solid scientific evidence. The objective of this study was to describe the levels of psychosocial health of a group of workers who were exercising using the Pilates technique. The influence of the job role of Pilates on psychosocial variables was also studied. 63 full-time workers (47 women and 16 men) belonging to different service sectors participated; 33 of them attended Pilates classes an average of 2.82 days per week, everybody else (the sedentary group) did not perform any physical activity. The results showed that the Pilates group registered higher levels of emotional stability and optimism than the sedentary group in Measurement 1. Furthermore, it has been confirmed that among the Pilates practitioners, managers have more control at work and less depressive symptoms and emotional stability than employees in both measurements. In conclusion, despite the many benefits attributed to practice Pilates and the growing interest among researchers to analyse their effects on health, the present study evidenced the absence of significant differences in psychosocial and occupational health after six months follow up.

The aims of the present study were: (i) describe patterns of sedentary behavior in Spanish adolescents; and (ii) IntroductionIn today's postmodern society, most people spend the majority of their waking hours engaging in sedentary behavior 1 . Emerging evidence shows that prolonged sedentary behavior may have a deleterious effect on health 2 . For example, excessive sedentary behavior has been associated with premature all-cause and cardiovascular disease mortality, obesity and an unfavorable cardiometabolic risk factor profile in adults 2 . Regarding this behavior in youth, although evidence is more limited, excessive sedentary behavior appears to have a harmful effect on health 3,4 . Consequently, educational and public health organizations have focused efforts on promoting a decrease in sedentary behavior from an early age 5 .Sedentary behavior includes activities that involve low levels of energy expenditure, consisting mainly of sitting time in different contexts 2 . Since several sedentary activities are part of young people's daily routine (e.g.: classes at school, studying), sedentary activities during leisure time are the target of preventive strategies 4 . Among youth, the most common leisure-time sedentary behavior is watching television (TV). Furthermore, new media technologies such as computers and games consoles have provided new opportunities for sedentary activity among this age group and while parents tend to limit the use of different kinds of media during child-ARTIGO ARTICLE
