The study was carried out on twelve males subjected to strength exercise. Before exercise, immediately after exercise, after 30 min and 24 h rest, the following parameters were estimated in blood samples collected from the body builders: levels of lactate (LA), reduced (GSH) and total glutathione (GSH+GSSG), glutathione reductase (GR) and creatine kinase (CK) activity, and lipid peroxidation products (TBARS) concentration. The applied strength test at the maximal intensity (LA 9.83±3.08 mmol•l-1) caused statistically significant increase of tested parameters after 24 h rest. The GSH/GSH+GSSG ratio decreased after 24 h (P<0.05). The positive correlation r=0.821 (P<0.001) between the creatine kinase activity (CK) and the lipid peroxidation products (TBARS) level was observed. It indicates there is relationship between the exercise – induced muscle damage and oxidative stress during the restitution.
