Impacto da suplementação de óleo de cártamo (Carthamus tinctorius L.) e/ou exercício físico sobre a composição corporal de ratos wistar.

Abstract

The practice of regular exercise is important to improve the quality of life. Oil supplements are sources of essential fatty acids and are related to changes in body composition. Safflower oil is cited as one of the lipids that reduces appetite and body fat. The aim of this study was to evaluate the effects of supplementation of safflower oil on body composition in rats submitted or not to exercise. We used 40 male rats divided into 4 groups: sedentary control (SC), exercised control (EC), sedentary safflower oil (SCO) and exercised safflower oil (ECO). The practice of exercise consisted in running on automatic treadmill for 45 min. at a speed of 21 m / min five times a week for four weeks. The groups received safflower oil by gavage, at 1ml / 100g, while the other groups received distilled water in the same ratio. After being anesthetized, the animals were weighed to murinométrica evaluation. Then removed and quantification of abdominal fat. The carcasses were gutted, weighed and crushed then homogenized. The fat and protein of the carcass was determined. Feed intake was measured weekly. The results showed that ECO group had lower values of BMI, waist circumference, chest circumference, visceral fat, body weight and carcass lipids, compared with the other groups (p <0.05). The SCO and ECO decreased feed intake and lower percentage carcass protein compared to SC and EC groups (p <0.05). Based on data, we concluded that safflower oil consumption associated with exercise can trigger on beneficial results regarding the change in body composition, specifically in weight loss.
