Abstract

Background and Aim: In today's world, physical activity along with balanced nutrition is definitely necessary to improve the quality of life and provide health. The purpose of this research is to investigate the effect of garlic consumption on serum glutathione, lactate dehydrogenase and creatine kinase in inactive people after a residual activity session. Materials and Methods: Ten healthy inactive students with an average age of 25.6±2.6 years and a body mass index of 23.5±1.7 kg/m2 randomly participated in this research. Subjects performed Bruce's training protocol twice with an interval of one week. Then the subjects consumed the supplement or placebo (1000mg capsule containing garlic powder or flour as a placebo) and then performed the residual activity. Independent and dependent t test was used to analyze the data at a significance level of 0.05. Results: Statistical results showed that the level of glutathione decreased significantly in both groups after exercise (P=0.001) and in the garlic supplement consuming group compared to the placebo group (P=0.001). The level of lactate dehydrogenase and creatine kinase increased in both the supplement (P=0.001) and placebo (P=0.001) groups after the residual activity, and there was no significant difference in the supplement user group compared to the placebo group (08 /0=P). Conclusion: The present research showed that acute consumption of garlic, probably by activating the glutathione peroxidase enzyme, increases the absorption of this antioxidant in response to the residual activity. Also, Bruce's residual-building exercise causes cell damage, and taking garlic supplements has no effect on the occurrence of cell damage.
