The purpose of this study was to evaluate the effects of swimming exercise in tibias of rats fed with different controlled diet. This study was approved by Ethical Committee in Animals Experiment. Ninety three‐month‐old male Wistar rats were randomly assigned to nine groups (n=10): (G1) normal diet control, (G2) hypo caloric diet control, (G3) hyper caloric diet control, (G4) normal diet 20‐minutes training, (G5) hypo caloric diet 20 minutes training, (G6) hyper caloric diet 20‐minutes training, (G7) normal diet 90‐minutes training, (G8) hypo caloric diet 90‐minutes training, e, (G9) hyper caloric diet 90‐minutes training. Hypo caloric diet is a 40% restriction of the total diet of the normal animals. Hyper caloric is 14% high‐fat diet. Normal diet is 4% fat. Physical exercise consisted of swimming on a large aquarium. Rats swam 5 days a week, 20 or 90 minutes, during 8 weeks. Tibias were dissected and tested in a universal testing machine. Data were analyzed using level of significance set at 5%. Data from our study suggest that bone resistance depends of the weight of animals acquired through diet. Swimming exercise programs did not alter mechanical properties of bones.
