[Influence of prolonged physical training on the composition of fatty acids of epididymal adipose tissue and of the carcass in the young rat on a dietary regime of sunflower, rapeseed or primor oil].
Weanling SPF male rats were fed for 12 weeks purified diets containing by weight 15 p. 100 sunflower oil, high erucic acid rapeseed oil or low erucic acid rapeseed oil. During the same period of time they were subjected to a moderate treadmill-running program and compared with sedentary animals fed the same diets. At the end of the experiment, epididymal and perirenal adipose tissues were removed and weighed, carcass lipids were extracted and weighed and their fatty acid compositions were determined by GLC on glass capillary columns. Training decreased body weight, fat pad weight and lipid content of the carcass. However the decrease of fat pad weight in response to exercise was more important in the case of perirenal adipose tissue than in that of epididymal adipose tissue. Fatty acid composition was greatly influenced by the nature of the dietary lipids but little affected by training. Palmitic, palmitoleic, oleic, linoleic and eicosenoic acid stores in the epididymal fat of trained rats decreased but not those of stearic, linolenic and erucic acids.
