Fatty acid contents in rat adipose tissues under anaerobic exercise and high-calorie diets

The objective of the paper is to study the effects of anaerobic exercise on fatty acids percentage in adipose tissues of different localization under high-calorie diets in rats. Materials and Methods. The authors examined Wistar rats under high calorie diets (32 % fat content). In the first group the animals were not exposed to any physical exercise. In the second group rats were exposed to anaerobic physical activity, namely swimming. The percentage of 24 fatty acids (FA) and the value of 14 integrative indicators (complexes) in the depot of visceral and subcutaneous adipose tissues were determined using chromatography-mass spectrometry (Agilent Technologies, USA). Results. Anaerobic exercise led to an increase in saturated FAs in the mesenteric adipose tissues and to a decrease in unsaturated FAs, as well as to a decrease in the unsaturation index; an increase in the retroperitoneal adipose tissue of the FA sphingophospholipid substrates, FA membrane substrates, a decrease in the energy substrates, an increase of vitamin F FA substrates due to a6 of unsaturated FAs...
