OLIVEIRA, Emerson Cruz de et al. Physical training promotes weight gain in malnourished rats without inducing oxidative stress. Motri. [online]. 2015, vol.11, n.2, pp.25-35. ISSN 1646-107X.  https://doi.org/10.6063/motricidade.3175.

The aim of the present work was to study the effect of physical exercise on oxidative stress of undernourished rats. Thirty-two female Fischer rats were equally divided into Sedentary Control (SC), Trained Control (TC), Sedentary Undernourished (SU), and Trained Undernourished (TU) groups. The training protocol consisted of swimming continuously for thirty minutes per day five days a week for eight weeks. The TU group showed greater weight gain and final weight compared to the SU one. The values of total sulfhydryl and superoxide dismutase showed no increase of stress because of the training, in the same way that liver damage was not evident. The SC and SU animals showed higher serum glucose values than the TC and TU animals, respectively. However, the oral glucose tolerance test confirmed the significant increase only for the SC compared to the TC group. We conclude that the physical training increased weight gain and final weight in malnourished animals without increasing oxidative stress in serum nor modifying the food intake or causing liver damage.
