Avaliação do efeito do óleo de cártamo sobre o comportamento de ratos submetidos ao treinamento físico.

Abstract

Safflower oil is used to synthesize CLA industrially, and its seeds are rich in glycerides esters of unsaturated fatty acids, oleic acid (W-9) and linoleic acid (W-6), and is considered an oil with high content of polyunsaturated fats -insaturadas. Its main function is to reduce body fat and increase muscle tone, arousing great interest to consumers and is much used as a supplement by physically active. The objective of this study was to evaluate behavioral changes in rats subjected to a diet supplemented with safflower oil with or without the physical training these animals. Wistar adult males, aged 60 days, weighing 250g ± 50g were divided into four groups: a control-sedentary group supplemented with distilled water (S-Control), a control-sedentary group supplemented with safflower oil (safflower-S) a group exercised supplemented with distilled water (and controls), another group exercised supplemented with safflower oil (E-safflower), all these groups received standard diet (AIN 93). Two tests were performed: open field and elevated plus-maze (EPM). In the test of the Open Field, four parameters were analyzed: (1) ambulation, which was no statistical difference between the control group and E-S-control groups, S-safflower (p <0.01), there was no statistical difference E-safflower group the. (2) rearing, where the E-control group showed that the amount of lift was higher than the other groups (p <0.001); (3) grooming was observed that the S-safflower group increased the time of self-cleaning with respect to the control group S (p <0.05); and (4) defecation, in which there was no statistical difference among the four groups. The E-control group had an increase in exploration activity / locomotor, not depending on the safflower consumption. In EPM, safflower S-E-groups and safflower (p <0.01) joined least in the closed arms than other control groups and S-E-control. As for the time spent in the closed arms there was no statistical difference among the four groups; All control groups E, E-and S-safflower safflower increased the number of entries into the open arms relative to the control group S (p <0.01); and the S-safflower group spent more time in the open arms when compared to the S-control groups (p <0.05) and there was no statistical difference between the control group and E-E-safflower. The E-safflower group spent less time in the downtown area when compared to the group and the control group (p <0.05). Therefore, this work has shown that consumption of safflower oil and exercise, when isolated, caused an anxiolytic effect in animals, however, the exercise did not potentiate the anxiolytic effect caused by safflower oil consumption.
