This study examined physiological variables of animals fed with a high-fat diet (HFD) or with a normal diet (ND) subjected to swimming at low and moderate level. Over 16 weeks, a group of animals was fed with HFD or ND, and at the 8 weeks, they started swimming with 50% or 80% of the maximum load achieved in the progressive work test. Weekly, body weight and the amount of ingested food were registered. The gly-cemic level was measured at the beginning, middle and at the end of the experiment. Adipose tissue, gastrocnemius muscles and hearts were collected for morphometry. The results showed that the animals fed an HFD had a minor caloric intake; however, the HFD increased body weight and adiposity, likely causing cardiac hypertrophy and an increase in the glycemic level. In this context, swimming with an 80% load contributed positively to weight control, adiposity, glycemic level, to control cardiac hypertrophy and induce hypertrophy in the gastroc-nemius muscle. All parameters assessed showed better results for the ND animals. Therefore, the importance of fat consumption was empha-sized in relation to obesity onset. The practice of swimming with an 80% load produced greater benefits than swimming with a 50% load for overweight treatment.
