Effects of a high-fat diet and swimming moderate training on postexercise metabolism in male adult rats

Abstract

The present study investigated the effects of high-fat diet and swimming moderate training on tissue weights, lipid profile and carbohydrate metabolism in the postexercise period. Male Wistar rats were maintained for eight weeks on either low or high-fat diet with or without swimming training (90 min/ day, five days/week). After the 8-wk diet/exercise treatments, animals were killed in rest or postexercise period (one and two hours). The high-fat diet produced greater retroperitoneal and epididymal white adipose tissues relative weights, greater glucose, triglyceride and cholesterol total, but smaller hepatic and muscle glycogen contents. On the other hand, swimming training resulted in smaller white adipose tissues and greater hepatic and muscle glycogen, but was not able to reduce the effects of the diet when was associated with the high-fat diet. The postexercise data suggest that recovery from exercise occur more rapidly in trained than in untrained rats. However, the trained and high-fat diet animals were not able to replet glycogen contents
