摘要：The purpose of the study was to verify the acute metabolic responses of rats to high intensity exercise. Rats were distributed in groups: resting (REP) and acute exercise (EA). EA group performed an exercise session that consisted in jumps (4x10 jumps) in a swimming pool, supporting a load of 50% of body weight. After sacrifice, blood samples were collected to determine serum glucose, insulin, cholesterol, fatty free acids and corticosterone. Gastrocnemius muscle, heart and liver were used to determine glycogen concentration. The acute exercise session promoted increase of serum glucose, fatty free acids and corticosterone concentration. Muscle and liver glycogen contents, as well as serum insulin concentration were reduced after single exercise session. We conclude that acute single high intensity exercise session promoted utilization of muscle and liver carbohydrate store and favored consumption of the lipid sources.
