Impacto da suplementação da amêndoa de baru (Dipteryx alata. Vog) sobre os parâmetros murinometricos de ratos exercitados.

Abstract

Physical exercise is capable of altering body composition, and it can be affected both positively and negatively by diet. Dietary lipids have been increasingly used as an ergogenic resource, being able to potentiate the results / performance achieved through exercise. A potential lipid source is baru almond, which in addition to having essential fatty acids still has considerable amounts of antioxidants. In view of the above, the objective of this work was to evaluate the impact of baru almond supplementation on the murinometric parameters of exercised rats. 48 male rats were divided into 4 groups: sedentary control (CS), exercised control (CE), sedentary baru (BS) and baru exercised (BE). The exercise practice consisted of a swimming protocol of 60 min / day for 8 weeks. The groups with baru received a dose of 2000mg / kg of body weight, while the other groups received distilled water in the same proportion. Weight and feed intake were measured weekly. At the end of the experiment the rats were euthanized by guillotine, then the murinometric evaluation was performed and organs, viscera and fat were removed for weight determination. No statistical difference was observed for body weight during the experiment (p< 0.05). The animals belonging to the experimental groups presented lower feed intake when compared to the animals from the CS and CE groups (p< 0.05). Regarding the murinometric parameters, the animals in the BE group (15.74 ± 0.54) had a larger circumference when compared to the CS group (14.89 ± 0.79) (p< 0.05). Regarding the fats, it was verified that the animals belonging to the EC group presented higher amounts of mesenteric fat compared to the animals of the CS group) (p< 0.05). For the retroperitoneal and epididimal fat, the animals in the BS group had higher amounts compared to the CS group) (p< 0.05). According to the results, it was observed that the use of baru kernel associated with the practice of physical activity was not able to reduce the weight and fat of the supplemented animals. However, other studies should be conducted in order to obtain more concrete data through more specific analyzes.
