Effect of Jujube Date Polysaccharide in Resisting Sports Fatigue

This study aims to explore effect of jujube date polysaccharide in relieving fatigue caused by sports taking rats as research object, in order to provide experimental basis for development of health care products made up of jujube date polysaccharide. Anti-fatigue effect of jujube date polysaccharide was observed through comparing duration of loaded swimming to exhaust, weight growth and content of blood lactic acid, blood urea nitrogen, blood glucose, muscle glycogen and hepatic glycogen of rats in sedentary group, control group and experimental group. Duration of loaded swimming to exhaust of weight-bearing rats in experimental group was obviously longer than control group; once the experiment ended up, weight of rats in experimental group was detected to be significantly higher than control group; after swimming, content of blood lactic acid and blood urea nitrogen of rats in experiment group was found to be decreased; rats taking medium and high dose jujube date polysaccharide had higher content of muscle glycogen and hepatic glycogen compared to control group. Thus the experiment proves that, jujube date polysaccharide can obviously strengthen the adaptive ability of human body to sports load, showing up its anti-fatigue effect.
