Avaliação de parâmetros físicos de ratos wistar suplementados com óleo de chia e submetidos ou não ao exercício físico regular.

Abstract

The practice of regular exercise combined with proper eating habits helps to treat and prevent obesity. Supplementation with foods rich in essential fatty acids have shown beneficiai effects on health and promote changes in the composition of body fat, as decreased body weight gain. The chia oil is a source of polyunsaturated fatty acids. The objective of this research was to evaluate whether supplementation with chia oil with or without exercises interferes with the physical composition in rats. Forty male rats were divided into 4 groups: Sedentary control (SC), exercised control (EC), sedentary chia oil (SO) and exercised chia oil (EO). The practice of exercise consisted in running on automatic treadmill for 40 min. tive times per week during four weeks. Groups with chia oil received the oil by gavage 1 ml / 1 OOg of body weight. The animais' body weight and feed intake were measured weekly. At the end of the experiment, the length, thoracic and abdominal circumference of the animais was measured using tape for analysis of murinométricos parameters, along with the weight, used to calculate the body mass index. Visceral fat was removed and weighed. Data shown that SO group had lower body weight compared to the SC during the second week. In the third week the SO group had lower body weight compared to SC and EC group. The EO group compared to the SC group had lower body weight. The SO and EO groups had lower body weight compared to the CS group in the fourth week (p <0.05). The SO and EO groups had lower values in feed intake when compared with the control group (p<0.05). The total visceral fat obtained a lower EO group compared with other three groups (p <0.05). According to the findings supplementation with chia oil associated with regular exercise has positive effects on decreased body weight and body fat composition.
