    Abstract:
    In order to evaluate the influence of physical exercise and protein intake on Resting Metabolic Rate (RMR) and Postprandial Energy Expenditure (PEE), 16 healthy, normal-weight, 15 year-old, adolescent males at the same stage of pubertal development were studied. They were assigned to two dietary groups receiving the same energy intake (1.3 x by measured RMR) and different proportions of macronutrients (13% protein, 39% fat, 48% CHO in Group A; 30% protein, 32%fat, 38% CHO in Group B). An increase in postprandial energy expenditure, relative to basal, was observed in all individuals. The postprandial energy expenditure was higher in group B than in group A. Postprandial Post-exercise Thermogenesis (expressed as Kcal/3h) was significantly higher in group B than group A (p<0.05). Although the significantly higher than on day 1 in group B (p<0.01). In group B, the post-exercise RQ was significantly lower than the preexercise RQ (p<0.01). It is concluded that in normal-weight-adolescents, a hyperproteic diet followed by moderately-intensive exercise induces increases in EE and decreases in RQ in the postprandial post-exercise period and is accompanied by increase in the RMR the following day.

Se evalúa la influencia del ejercicio físico y de la ingesta proteica sobre el Gasto Energético Basal (GEB) y el Gasto Energético Postprandial (GEP), en 16 varones sanos, adolescentes de 15 años de edad en el mismo estadio de desarrollo puberal, en normopeso. Se reparten al azar en dos grupos que reciben la misma cantidad de energía (1,3 x GEB medio) y diferente proporción de macronutrientes (grupo A: 13% proteínas, 39% lípidos, 48% hidratos de carbono; grupo B: 30% proteínas, 32%lípidos, 38% hidratos de carbono). En todos los individuos se observa un aumento en el GEP respecto al GEB, el cual es superior en el grupo B. La termogénesis postprandial post-ejercicio (Kcal/3h) es significativamente superior en el grupo B (p<0.05). Aunque el GEB en el día 1 no se diferencia entre los dos grupos, el del día 2 es superior en el grupo B (p<0.01), siendo en este grupo, el cociente respiratorio post-ejercicio, significativamente menor respecto al cociente respiratorio pre-ejercicio (p<0.01). Se concluye que, en adolescentes en normopeso, una dieta hiperproteica seguida de un ejercicio físico de intensidad moderada, induce a un aumento del GE y una disminución del cociente respiratorio durante el período postprandial post-ejercicio, acompañándose de un aumento del GEB del día siguiente.
