Significant differences (P < 0.01) *after exercise vs. before exercise, # men vs. women; ox-LDL – oxidized low-density lipoprotein, 3-NT – 3-nitrotyrosine, TAC – total antioxidative capacity, Lac – plasma lactate concentration, CK – creatine kinase activity in serum, LDH – lactate dehydrogenase activity in serum.
