Abstract ObjectiveThe objective was to look into the effects of intermittent swimming against continuous exercise and inactivity in Wistar rats after they developed exogenous obesity though the consumption of a palatable fat-rich diet. The following was investigated: evolution of body weight, food intake, adiposity, fat percentage in tissues and lipid profile.MethodsAdult rats were kept in individual cages with free access to food and water. The experimental protocol included: 1) development of exogenous obesity (3 weeks). The animals were divided into S - inactive animals fed the standard Primor(R) diet (n=8) and HF - inactive animals fed a high-fat diet (n=32); 2) Treatment (the 8 following weeks) - the animals (n=24) were given the standard diet and divided into an inactive group, a continuous training group and an intermittent training group. Training occurred 5 times per week and was either continuous (90 minutes per day) or intermittent (3 times 30 minutes per day). The animals were killed at 3 and 8 weeks and the fat tissues, the liver and the blood were collected. Adiposity, fat percentage of the fat tissues and liver, gain of body weight, food consumption and lipid profile were determined.ResultsThe high-fat diet increased adiposity, percentage of fat in the liver, and induced dyslipidemias. Diet change and the two types of training were capable of reducing exogenous obesity. However, intermittent exercise was more efficient in reducing adiposity and preventing weight gain.ConclusionWhen associated with a balanced diet, the trainings used in this study can be used as a strategy to control weight and dyslipidemias, both in experimental models and in human beings.
