- Abstract
Introduction: Acute exhaustive exercise increases reactive oxygen species, which may decrease antioxidant capacity of the body. Regular exercises and antioxidants consumption can improve antioxidant capacity. The present study aimed to determine the protective effect of pomegranate peel hydroalcoholic extract supplementation on oxidative responses induced by an exhaustive exercise schedule in rats. Materials and Methods: Thirty-two male rats were randomly divided into four groups of eight: control group received saline, PPHE200 group received 200 mg/kg pomegranate peel hydroalcoholic extract orally, PPHE250 gorup received 250 mg/kg pomegranate peel hydroalcoholic extract orally, and Vit E group received 5 mg/kg vitamin E orally. After eight weeks of regular exhaustive exercise the activity level of glutathione peroxidase, catalase, reduced glutathione and lipid peroxidation was measured. Results: The activity of glutathione peroxidase, catalase and reduced glutathione significantly increased in PPHE200, PPHE250 and vit E groups than in the control (p< 0.05). Malondialdehyde level significantly reduced in PPHE200, PPHE250 and vitE groups than in the control (p< 0.05). Conclusion: The results showed that pomegranate peel hydroalcoholic extract supplementation may be beneficial in improving antioxidant defense system and in reducing oxidative stress induced by an exhaustive exercise.
