摘要

Compare the cardiovascular effects of rhEPO on rats under chronic vs acute exercise. Chronic exercise (swimming: swi) in male rats for 10 wks: control - sedentary (SED); rhEPO - 50 IU/Kg/wk; swimming (EX) - 1 hr, 3 times/wk; EX+EPO. For the extenuating exercise (rhEPO given for 3 wks prior exercise): swi (Swi); Swi+EPO; running (Run); Run+EPO.The chronic EX+EPO rats showed higher values of RBC, Htc and Hb vs EX and vs Swi+EPO of the acute sessions. Both chronic and acute swimming showed a remarkable sympathetic and serotonergic activation. rhEPO treatment in chronic training has promoted oxidative stress, in contrast with the antioxidant effect on Swi and Run of acute exercises.rhEPO doping is more deleterious in rats mimicking trained athletes (chronic) than in occasional abusers (acute), due to increased CV risk.
