and Sleep DurationLabree W, van de Mheen D, Rutten F, Rodenburg G, Koopmans G, Foets M 2015A cross-sectional survey was performed to examine to what degree differences in overweight and obesity between native Dutch and migrant primary school children could be explained by differences in physical activity, dietary intake, and sleep duration among these children. Subjects (n=1943) were primary school children around the age of 89 years old and their primary caregivers: native Dutch children (n=1546), Turkish children (n=93), Moroccan children (n=66), other non-western children (n=105), and other western children (n=133). Multivariate regressions and logistic regressions were used to examine the relationship between migrant status, childs behavior, and BMI or prevalence of overweight, including obesity (logistic). Main explanatory variables were physical activity, dietary intake, and sleep duration. We controlled for age, sex, parental educational level, and parental BMI. Although sleep duration, dietary intake of fruit, and dietary intake of energy-dense snacks were associated with BMI, ethnic differences in sleep duration and dietary intake did not have a large impact on ethnic differences in overweight and obesity among children from migrant and native origin. It is suggested that future preventive strategies to reduce overweight and obesity, in general, consider the role of sleep duration. Also, cross-cultural variation in preparation of food among specific migrant groups, focusing on fat, sugar, and salt, deserves more attention. In order to examine which other variables may clarify ethnic differences in overweight and obesity, future research is needed.Endurance Exercise-Induced Cardiac Remodeling: Not All Sports Are Created EqualMeagan M. Wasfy, MD, Rory B. Weiner, MD, Francis Wang, MD, Brant Berkstresser, MS, ATC, Gregory D. Lewis, MD, James R. DeLuca, BA, Adolph M. Hutter, MD, Michael H. Picard, MD, and Aaron L. Baggish, MD 2015The term endurance sport (ES) is broadly used to characterize any exercise that requires maintenance of high cardiac output over extended time. However, the relative amount of isotonic (volume) versus isometric (pressure) cardiac stress varies across ES disciplines. To what degree ES-mediated cardiac remodeling varies, as a function of superimposed isometric stress, is uncertain. The aim of this study was to compare the cardiac remodeling characteristics associated with two common yet physiologically distinct forms of ESDesarrollo de los componentes sociales de la deportividad en futbolistas alevinesLamoneda Prieto J, Huertas Delgado, FJ, Cordoba Caro LG, Garcia Preciado AV 2015El futbol base demanda de un tratamiento etico que incluya no solo aspectos como el respeto, sino tambien: la cortesia, generosidad y ayuda. El objetivo del presente estudio fue elaborar un programa de intervencion especificamente disenado para jugadores de futbol alevin centrado en la mejora de los aspectos sociales de la deportividad y analizar el cambio que genera. Participaron ciento veintiseis (n = 126) futbolistas federados de entre 10 y 12 anos de edad. Se utilizo un diseno cuasi-experimental, con una fase de intervencion de seis semanas de duracion. Se administro la subescala factores sociales de la deportividad de la Escala Multidimensional de Orientaciones hacia la deportividad adaptada al futbol base (Lamoneda, Huertas, Cordoba y Garcia, 2014). En el analisis estadistico se recurrio a la prueba de Willcoxon y
