The Effect of Short-term Spirulina Supplementation on Oxidative Stress Status in Obese Men Following Resistance Exercise

This study aimed to evaluate the effect of spirulina supplementation on oxidative stress markers (TAC and MDA) in the obese men after a resistance exercise session. In this study, 20 obese men were randomly divided into two groups of experimental (n = 10) and control (n = 10). The experimental group received 2 spirulina tablets (500 mg) daily for two weeks, and the control group received the same amount of placebo. After two weeks of the supplementation, the individuals from both groups participated in a resistance exercise session. Blood samples were collected in three steps; before supplementation, before, and 24 hours after resistance exercise. Results showed that the TAC and MDA concentration of the biomarker in the experimental group were respectively increased and decreased significantly in the control group over time (p ≤ 0.05). This study showed that the supplementation with Spirulina could increase the plasma antioxidant capacity which reduced the lipid peroxidation in obese men after the resistance exercise.
