This paper focus on the effects of puerarin remit sports fatigue by observeing the effects of puerarinon blood
components and exercise ability of mice in swimming trained. Comparing with the time of exhaustive swimming in the
swim trained group, swim trained group with puerarin significantly increase (P<0.05). The puerarin may reduce the increase
of hemoglobin, red blood cell and platelets caused by endurance exercise, reduce the blood viscosity, prolong the
time of exhaustive swimming and improve exercise ability of mice in swim trained. Through the rat swimming experiment,
we can further know the effects of puerarin on alleviating sports fatigue are obviously, which plays a role in the research
field of the physiological effect of puerarin.
