Dietary Supplementation with the Microalga Galdieria sulphuraria (Rhodophyta) Reduces Prolonged Exercise-Induced Oxidative Stress in Rat Tissues

Figure 6

Effect of prolonged exercise and G. sulphuraria treatment on rat liver, heart, and skeletal muscle content of reduced glutathione (GSH) (a) and GSH/GGSG ratio (b). Values are mean ± S.E.M. For each value eight rats were used. GSH is expressed as nmol GSH per g of tissue. S: sedentary untreated rats; SG: sedentary G. sulphuraria treated rats; E: exercised untreated rats; EG: exercised G. sulphuraria treated rats. Significant difference for exercised rats versus respective sedentary controls; significant difference for G. sulphuraria treated animals versus respective untreated controls. The level of significance was chosen as .
