Three months of interdisciplinary rehabilitation increases respiratory muscle strength in obese schoolchildren

Abstract

At present, there is no evidence regarding the effects of an interdisciplinary program, based on physical training, on respiratory muscle strength (FMR) in obese schoolchildren. The objective was to analyze the effects of a three-month interdisciplinary intervention program on fat mass (MA), muscle mass (MM) and FMR in schoolchildren with childhood obesity and without respiratory pathology. 11 schoolchildren, seven males and four female, participated during three months of the interdisciplinary program. Supervised by nutritionists, psychologists and trainers. FMR was evaluated with pimometry and body composition (CC) with anthropometry. There was a significant increase in FMR, expressed as maximum inspiratory pressure (PIM) (p = 0.029) and maximum expiratory pressure (PEM) (p = 0.006) in relation to their reference and absolute values. A significant decrease in the BMI score was found (p = 0.04), as well as associations between PIM (PIM / MA p = 0.005; r = -0.769) and PEM (PEM / MM p = 0.001; r = 0.835) with variables of CC. In conclusion, three months of interdisciplinary treatment of childhood obesity evoke increases in PIM and PEM, and these increases are associated with variations in CC

Actualmente se desconocen los efectos de un progra-ma interdisciplinario, basado en entrenamiento físico, sobre la fuerza muscular respiratoria (FMR) de escolares obesos. El objetivo es analizar los efectos de un progra-ma de intervención interdisciplinario de 3 meses de du-ración sobre la masa adiposa (MA), masa muscular (MM) y la FMR en escolares con obesidad infantil y sin pato-logía respiratoria. 11 escolares, 7 de género masculino y 4 de género femenino, participaron durante 3 meses del programa interdisciplinario, atendidos por nutricio-nistas, psicólogos y entrenadores. Se evaluó FMR con pimometría y composición corporal (CC) con antropo-metría. Se observó el aumento significativo de la FMR expresada en presión inspiratoria máxima (PIM) (p = 0.029) y presión espiratoria máxima (PEM) (p = 0.006) en relación con sus valores de referencia y valores absolu-tos. Se observó una disminución significativa en el IMCz score (p = 0.04) y se encontraron asociaciones signifi-cativas entre PIM (PIM/MA p = 0.005; r = -0.769) y PEM (PEM/MM p = 0.001; r = 0.835) con variables de la CC. En conclusión, 3 meses de tratamiento interdisciplinario de la obesidad infantil evocan incrementos en la PIM y PEM y estos incrementos se asocian a variaciones en la CC
