“…Indirect calorimetry is a way to determine the use of energy substrates in the presence of O 2 and release of CO 2 by the analysis of air inhaled and exhaled by the lungs [36]. The amount of carbon dioxide produced, compared with the oxygen consumed during the oxidative processes, ranges according to the oxygen content present in oxidizable substrate.…”

Occidental life styles, including physical inactivity, are related to risk of developing heart diseases. To prevent or even mitigate these effects, the frequent recommendation has been the practice of physical exercise as a measure of therapeutic interaction in preventive medicine and rehabilitation. Thus, our study was carried out to evidence the effects of aerobic physical exercise regularly practiced, through swimming, calorimetry, lipid profile, and oxidative stress in myocardium. Thirty-two Winstar rats, males, 75 days old were used. Animals were divided into two groups: C (n=8) as the control, which received food and water ad libitum and TR (n=8) as the trained group received the same treatment as C and animals in this group were submitted to swim. Swimming was used as a model of exercise with moderate intensity training for eight weeks. The experimental design was completely randomized with 16 treatments and eight replications, with a significance level of 5% probability. Calorimetry shows lower carbohydrate oxidation and increased lipid oxidation in C when compared with TR. The trained group had higher glucose, higher HDL-cholesterol and lower accumulation of triglycerides, and verified the protective effect in cardiac tissue. Thus, we can conclude that the swimming protocol was effective in controlling deleterious effects caused by poor habits on the myocardium.

“…Así, el gasto de energía en la actividad física no tuvo efecto sobre la composición corporal y el metabolismo energético de las mujeres estudiadas. Cabe señalar que el trabajo muscular de baja intensidad conduce principalmente a la oxidación de hidratos de carbono 36 , la cual tiende a ser mayor en sujetos con exceso de peso ya que muestran tendencia a ahorrar energía, además de su mayor eficiencia metabólica 37 .…”

“…Prentice y col 37 observaron que la predisposición a la obesidad puede ser producto del metabolismo más económico que busca mantener la masa corporal estable. Ravussin y col 28 encontraron que los individuos con características físicas similares pueden requerir más o menos energía para mantener su peso corporal y pueden presentar diferencias en la eficiencia metabólica.…”

Fundamentos. El objetivo de presente trabajo es evaluar la composición corporal y el metabolismo energé-tico en mujeres con exceso de peso corporal.Material y métodos. Estudio transversal de intervención no randomizado con 40 mujeres [26 con exceso de peso (G1) y 14 eutróficas (G2)]. Fueron realizadas evaluaciones dietéticas, antropométricas y de la composición corporal (bioimpedancia eléctrica), actividad física (acelerómetro tridimensional) y metabolismo energético (calorimetría indirecta). resultados.No hubo diferencia en la ingesta energética y en la actividad física entre los grupos. Los paráme-tros de composición corporal fueron superiores en G1, excepto el agua corporal total. Hubo asociación entre el gasto energético y la composición corporal. La masa corporal magra fue el principal determinante del gasto energético. No hubo diferencia de los parámetros metabólicos entre los grupos, pero se sugiere menor velocidad de oxidación de los nutrientes y mayor eficiencia metabólica en G1.conclusiones. El exceso de peso corporal se asoció con cambios en la composición corporal y en el metabolismo energético que justifican la acumulación de grasa corporal.Palabras clave. Obesidad. Composición corporal. Metabolismo energético. Dieta. aBstractBackground. The objective of this paper is to evaluate body composition and energy expenditure in women with excess body weight.Methods. There was a non-randomized, cross-sectional study with 40 women, [26 with excess weight (G1) and 14 eutrophic (G2)]. The following evaluations were made: dietetic, anthropometric and body composition (electrical bioimpedance), physical activity (threedimensional accelerometer) and energy expenditure, basal and resting (indirect calorimetry).results. The energy intake and physical activity did not differ between groups. The parameters of body composition were higher in G1, except total body water. There was a relationship between energy expenditure and body composition. The lean mass was the biggest determinant of energy expenditure. There was no difference in metabolic parameters between groups, but lower nutrient oxidation and increased metabolic efficiency in G1 was suggested.conclusion. Excess weight was associated with body composition and energy expenditure changes that justify the accumulation of body fat.
