| Abstract: | Aim To analyze the biochemical mechanisms of the effects of vitamin B12 and folic acid on exercise capacity and their complementary approaches and to provide theoretical support for the prevention and correction of pernicious anemia for endurance athletes and fitness community.Methods Literature review research methods are adopted.By reading 33 domestic and foreign references,the mechanism of vitamin B12 and folic acid for promoting the maturity of red blood cell,improving endurance exercise level and preventing pernicious anemia is investigated systematically and comprehensively.Results The biochemical mechanism of the effects of vitamin B12 and folic acid on exercise capacity is made clear,and the suitable supplementation of vitamin B12 and folic acid can help prevent the occurrence of pernicious anemia.Conclusion Based on the biochemical mechanisms of vitamin B12 and folic acid,compatibility should be taken for the supplementation of vitamin B12 and folic acid.2.4 μg/d of vitamin B12 and 400 μg/d of folic acid are suitable for adults,while athletes can increase the dose of vitamin B12 and folic acid in high-intensity exercise training. |
