ABSTRACT
We investigated the effect of the extract from fruits of Aronia melanocarpa (AM), containing the anthocyanin antioxidants on the lipid peroxidation index (TBARS) and the content of reduced glutathione (GSH) in rat tissues at rest and after exercising until exhaustion on a treadmill. For four consecutive days the animals were given AM through a gastric probe at 0.7 mg• kg-1 body mass (related to the content of the active substance). Control rats received 0.9% NaCl solution. Samples of the liver (L), heart (H), and white (WG) and red (RG) portions of the gastrocnemius muscle were collected from the animals at rest and immediately after the exercise. No effect of AM on TBARS was detected in the resting animals. The exercise, however, led to the significant elevation of the value of this index (P
