Abstract

ABSTRACT This study was planned in order to investigate the protective effect of prolonged quercetin supplement on oxidative stress and antioxidant enzyme activities in boxers. It included 20 voluntary male boxers. The athletes were separated into two groups as the control group (n = 10) and Quercetin group (n = 10). The athletes were supplemented with 500 mg quercetin for 30 days before their exercise programs. Blood samples were drawn from the athletes before and after exercising. MDA, SOD, CAT and GSH analysis were performed. According to the findings, there were an increase in the MDA levels of the control group (P<0.01) and a significant decrease in the MDA levels of quercetin group (P<0.001) when they were compared after being given quercetin. The levels of antioxidant enzymes SOD, CAT and GSH significantly increased in quercetin group (P<0.001). As a conclusion; it can be said that quercetin supplement has protective effect against oxidative stress by decreasing the amount of MDA, which is the end-product of lipid peroxidation and increasing the activity levels of the antioxidant enzymes SOD, CAT and GSH.

长期补充槲皮素对拳击手氧化应激和抗氧化酶活性的保护作用

摘要本研究旨在研究长期补充槲皮素对拳击手氧化应激和抗氧化酶活性的保护作用。其中包括20名自愿参加的男性拳击手。运动员分为对照组（n=10）和槲皮素组（n=10）。运动员在运动前30天补充500毫克槲皮素。在运动员运动前后抽取血样。进行MDA、SOD、CAT和GSH分析。结果表明，槲皮素组与对照组相比，MDA含量升高（P<0.01），MDA含量显著降低（P<0.001）。槲皮素组抗氧化酶SOD、CAT和GSH水平显著升高（P＜0.001）；可以说，槲皮素补充剂通过降低脂质过氧化的最终产物MDA的含量和提高抗氧化酶SOD、CAT和GSH的活性水平，对氧化应激具有保护作用。

期刊介绍： Studies on Ethno-Medicine is a peer reviewed, internationally circulated journal. It publishes reports of original research, theoretical articles, timely reviews, brief communications, book reviews and other publications in the interdisciplinary field of ethno-medicine. The journal serves as a forum for physical, social and life scientists as well as for health professionals. The transdisciplinary areas covered by this journal include, but are not limited to, Physical Sciences, Anthropology, Sociology, Geography, Life Sciences, Environmental Sciences, Botany, Agriculture, Home Science, Zoology, Genetics, Biology, Medical Sciences, Public Health, Demography and Epidemiology. The journal publishes basic, applied and methodologically oriented research from all such areas. The journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscript of unusual interest. Further, the manuscripts are categorised under three types, namely - Regular articles, Short Communications and Reviews. The researchers are invited to submit original papers in English (papers published elsewhere or under consideration elsewhere shall not be considered).
