Green tea extract can increase exercise endurance and has the effect of anti fatigue

Recently, a study by Liaoning Normal University in China found that EGCG, an epigallocatechin extracted from green tea (http:// can increase exercise endurance and has the effect of anti fatigue The research results have been published in the Journal of Pharmacognosy This study has the potential to show that EGCG can be used in natural health care products (http:// to recover exercise fatigue and alleviate exercise-induced oxidative damage The researchers randomly divided the mice into four groups: the control group and the experimental group (taking 50, 100, 200mg / kg EGCG) for 28 days On the last day of the trial (http:// the researchers forced mice to swim to assess the effect of EGCG on physical strength The results showed that compared with the control group, EGCG supplementation could reduce the content of lactate and creatine kinase (one of the markers of muscle injury) in the blood of animals, and also reduce the content of malondialdehyde (one of the markers of oxidative stress) The researchers also found that EGCG can increase glycogen content in the liver and muscle of mice, which shows that EGCG can increase exercise endurance, and also increase the activity of antioxidant enzymes, such as superoxide dismutase, catalase, glutathione peroxidase Green tea contains 30% - 40% water extracted tea polyphenols, while black tea contains 3% - 10% water extracted tea polyphenols Oolong tea is a semi fermented tea between black tea and green tea According to Zhiti (http:// bridge media, the four main tea polyphenols in fresh tea are EGCG, epigallocatechin (EGC), epigallocatechin gallate (ECG) and epigallocatechin (EC) Several studies have confirmed that green tea (Camellia sinensis) and its active ingredients are beneficial to human health (http:// especially EGCG At present, the results show that EGCG has a dose-dependent anti fatigue effect, and the best effect is when the intake dose is 200mg / kg In the review of previous studies, the researchers pointed out that the anti fatigue mechanism of EGCG may be related to the protective effect of microparticle membrane, mainly through modifying a variety of antioxidant enzyme activities to prevent lipid oxidation In the future, it is necessary to elucidate the molecular mechanism of EGCG and the gene regulation related to anti fatigue
