Abstract

The invention relates to a sport fatigue resisting folic acid layered double hydroxide (LDH) nano nutritional supplement and a preparation method thereof. The sport fatigue resisting folic acid LDH nano nutritional supplement is prepared by a co-precipitation method, and the functions thereof in resisting oxidation in vitro and resisting sports fatigue in vivo are studied. Folic acid has a relatively strong anti-oxidation function and plays an important role in maintaining the body function level, promoting fatigue recovery and enhancing body immunity. In the invention, the sport fatigue resisting folic acid layered double LDH nano nutritional supplement is synthesized by use of the advantages of a layered inorganic nano material (LDH) serving as a drug carrier; the invention has an important application value in developing a functional sport nutritional supplement.

Description

Technical field [0001] The invention belongs to the technical field of nano material preparation, and in particular relates to an anti-sport fatigue folic acid layered double hydroxide nano nutritional supplement and a preparation method thereof. Background technique [0002] Exercise fatigue refers to the inability of the body's physiological processes to maintain its function at a certain level and the inability to maintain a predetermined exercise intensity. The increase in oxygen consumption of the body during or after exercise, or the activation of specific pathways, is the main source of reactive oxygen radicals (ROS). Studies have shown that with the increase of exercise intensity and time, the production of free radicals increases sharply. When the body's own ability to scavenge free radicals is exceeded, the anti-oxidant level of tissues decreases, and the body produces a state of oxidative stress. Exercise oxidative stress caused by free radicals is one of the main cau...
