Abstract
To evaluate the physical and chemical properties of polysaccharides from selenium-rich tea and the effects of these polysaccharides on swimming performance and recovery from swimming-induced fatigue in mice. By setting up a 5-week endurance exercise model in mice and the mice were given by oral gavage different doses of Limonium sinense (Girard) Kuntze (LSK). The swimming exhaustion time of mice was recorded and the concentrations of blood glucose, Blood Ureanitrogen (BUN), Blood Lactic Acid (BLA) and the contents of hepatic glycogen and Malonaldehyde (MDA) as well as the activity of Hepatic Glutathione Peroxidase (GSH-Px) were measured immediately and at 24 h after exhaustive exercise. LSK were Se-binding glycoproteins and could prolong the swimming exhaustion time, improve the carbohydrate metabolism, significantly increase the activity of GSH-Px and reduce the content of MDA in liver tissue of mice. LSK have an anti-fatigue effect in mice and the underlying mechanism is related to regulating the carbohydrate metabolism and improving tissue lipid peroxidation caused by excessive exercise.
Highlights
Limonium sinense (Girard) Kuntze (LSK), a traditional Chinese folk herbs, is a white Danko perennial herb
After 24 h recovery, blood glucose in mice in each group recovered well, but there was no significant difference between the groups, which is related to the body glucose homeostasis
This showed that after the sucrose and LSK polyphenols participated in the energy supplying, the protein catabolism was significantly saved in mice
Summary
LSK, a traditional Chinese folk herbs, is a white Danko perennial herb. The roots or the whole palnt can tonify the spleen, enrich the blood, invigorate the circulation of blood, stop bleeding and regulate the menstrual, mainly used for the treatment of colds, blood loss, blood heat and menorrhagia embolism (Jun and Binghua, 2008). LSK polyphenol extract has a strong capacity of scavenging free radical and the activity is stronger than the synthetic antioxidants-BHT which is of the same concentration (Bingha and Jing, 2013). The activity of scavenging free radicals in natural extract is often depended on its antioxidant capacity. For the further study of the antioxidant capacity of LSK and a comprehensive understanding and evaluation of LSK antioxidant potential of polyphenols extracted material, we base our theory on the special physiological phenomenon of endurance-sports fatigue and biological activity of polyphenol extract. We obtained LSK polyphenol extracts from the roots with ultrasonic assisted extraction-macroporous resin adsorption, established a five weeks model of mice endurance-sports, detected the effects of LSK on mice endurance exercise, behavioral manifestations and fatigue recovery by feeding different doses of LSK polyphenol solution, aimed to provide experimental support for the further development of natural antioxidants and sports supplements
