The animals were divided into 3 groups sedentary control group C an exercise group that received a control chow EX and an exercise group that received a chow supplemented with oat bran EX-O . Exercised groups were submitted to an eight weeks swimming training protocol. In the last training session the animals performed exercise to exhaustion . incapable to continue the exercise . After the euthanasia of the animals blood muscle and hepatic tissue were collected. Plasma cytokines and corticosterone were evaluated. Glycogen concentrations was measured in the soleus and gastrocnemius muscles and liver. Glycogen synthetase-a gene expression was evaluated in the soleus muscle. Statistical analysis was performed using a factorial ANOVA. Time to exhaustion of the EX-O group was 20 higher 515 3 minutes when compared with EX group 425 3 minutes p . For hepatic glycogen the EX-O group had a 67 higher concentrations when compared with EX p . In the soleus muscle EX-O group presented a higher glycogen concentrations when compared with EX group p . TNF-a was decreased IL-6 IL-10 and corticosterone increased after exercise and EX-O presented lower levels of IL-6 IL-10 and corticosterone levels in comparison with EX group. It was concluded that the chow rich in oat bran increase muscle and hepatic glycogen concentrations. The higher glycogen storage may
