Abstract

Background & Objective: Physical inactivity is linked to elevated oxidative stress and impaired antioxidant defense, increasing the risk of chronic disease. Purslane, a plant rich in omega-3 fatty acids and polyphenols, may enhance antioxidant capacity. This study investigated the effect of endurance training and purslane supplementation on superoxide dismutase (SOD) and catalase (CAT) in inactive men. Methods: Thirty-two inactive men (20–40 years) were randomly assigned to four groups: Control (C), Purslane (P), Training (T), and Training + Purslane (T+P). The training groups (T, T+P) performed progressive treadmill endurance exercise three times per week for eight weeks. Supplement groups (P, T+P) received 1200 mg/day purslane. Serum SOD and CAT were measured pre- and post-intervention. Data were analyzed using one-way ANOVA and Tukey post-hoc tests. Results: Significant group effects were found for SOD and CAT (p<0.001). The T+P group showed the greatest increases versus C and T (p<0.01). P also improved both enzymes (p<0.05). Conclusion: Purslane supplementation, especially when combined with endurance training (T+P), markedly improves antioxidant enzyme activity in inactive men.
