Findings indicate that when specific task structures associated with a mastery climate are included in an instructional setting, these climate manipulations seem to have a direct effect on physical activity levels once the children learned how to manage themselves in the setting. Free-play activity in and of itself does not appear to stimulate MVPA.
El propósito de esta investigación fue determinar la relación entre la aptitud física y los niveles depresivos en las personas adultas mayores que participan en programas de actividad física en el área de San Ramón, Alajuela. Un total de 138 personas mayores con edades entre los 60 y 86 años (67.94 ± 5.26 años), fueron medidas en los componentes de la aptitud física mediante la prueba “Senior Fitness Test” (SFT) y los niveles de depresión mediante la Escala de Depresión Geriátrica de “Yesavage” (GDS, “Geriatric Depression Scale” por sus siglas en Inglés). Los resultados sugieren que el 97,8 % de las personas analizadas se ubicó dentro de los parámetros normales y excelentes de aptitud física, mientras tanto, el 86,2 % se encontró en la etapa normal de la depresión. Por su parte, la depresión geriátrica correlacionó negativamente con la aptitud física en las variables: fuerza muscular y resistencia corporal de la parte baja del cuerpo, resistencia de la fuerza muscular del brazo, la agilidad y equilibrio dinámico, y flexibilidad parte baja del cuerpo (p <0,05). Se concluye que a mayor nivel de aptitud física menor son los rasgos depresivos en personas adultas mayores.
PurposeThe present study examined changes in body composition, maximum oxygen uptake, and physical activity in sedentary office employees prescribed with two different walking programs during a 10-week intervention.Methods68 sedentary employees were randomly assigned to one of three groups: multiple bouts of walking (n = 24 (5 male, 19 female) Age = 46±9, BMI = 30.5±5.78 kg/m2), continuous walking (n = 22 (6 male, 16 female) Age = 48±9, BMI = 30.6±6.2 kg/m2) and the control group (n = 22 (5 male, 17 female) Age = 42±10, BMI = 27.5±5.23 kg/m2). Dual-energy X-ray absorptiometry (iDXA) assessed body composition and a Bruce protocol treadmill test assessed aerobic fitness at baseline and week 11. At baseline, week 6 and week 11 a waist worn accelerometer measured physical activity and sedentary behavior. Physical activity was measured throughout the program with a wrist worn accelerometer.ResultsThe results from the mixed-design ANOVA show that fat mass (p < .000) and fat percentage (p < .000) decreased for all three groups as a main effect of time. Sedentary behavior did not change (p>0.05) for all three groups. Moderate intensity physical activity increased significantly from pre-test to week 6 (p<0.05), then decreased from week 6 to post-test (p<0.05), with no significant changes observed from pre-test to post-test (p>0.05) for all groups. No changes in VO2 were observed (p>0.05) for all groups.ConclusionsContinuous or intermittent walking activity produce similar benefits on body weight, fat mass and body fat percentage in sedentary employees. Meanwhile, intermittent walking allowed these sedentary employees to increase lean mass and fat free mass. Intermittent walking could provide at least similar benefits on body composition compared to a continuous walking program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
