- Dual-energy X-ray absorptiometry and forced expiratory volumes in sedentary and trained children Álvaro Fernández-Luna María Plaza-Carmona Esther Ubago-Guisado Ignacio Ara María Martín-García Jorge García-Unanue Leonor Gallardo Multidisciplinarias (Ciencias Sociales) DXA fat mass physical activity forced expiratory volumes Information regarding the influence of physical activity and fat mass in the human trunk on respiratory health is scarce. The aim of this study was to evaluate the influence of body composition and physical activity in for- ced expiratory volumes in children. The sample comprised 87 children between 8 and 13 years of age (9.62 ± 1.25), at Tanner stages I-III, participated in this study. Sixty played sports (trained children, TC) and 27 were assigned to the sedentary children control group (SC). Body composition (DXA), anthropometric variables (weight and height), and forced expiratory volumes (FEV1 and FVC) were determined in all subjects. Results showed that higher FEV1 and FVC values were found in the SC group compared to the TC group. Multiple regression analysis showed that physical activity, total fat mass, and android fat mass, had the highest pre- dictive value for FVE1 as did height for the FVC. In SC group there was a positive association between FEV1/FVC ratio and Body Mass Index and trunk fat mass. We did not find any associations between forced respiratory volumes and the whole body and trunk region fat mass in trained and sedentary children. 2015 artículo científico 1885-3137 https://www.redalyc.org/articulo.oa?id=71041417004 en http://www.redalyc.org/revista.oa?id=710 RICYDE.
