Ergogenic Influence of Erythrocyte Reinfusion: Aerobic Power and Thermoregulation

摘要

The authors measured the physical exercise capabilities of the U.S. Army Special Forces soldiers (male) and determined the subsequent ergogenic influence of autologous erythrocyte reinfusion. Twelve subjects (Ss) completed maximal exercise treadmill testing in a comfortable environment. Six Ss were later transfused with a 600 ml autologous erythrocyte in a NaCl glucose-phosphate solution and completed identical maximal exercise tests approximately 3 and 10 days post-transfusion. For the 6 reinfused Ss, hemoglobin (Hb) and erythrocyte volume (RCV) increased 10% (p<0.05) VO2 and 11% (p<0.05), respectively, post transfusion. The authors concluded that induced polycythemia can have an ergogenic effect by increasing maximal aerobic power and enhancing the thermoregulatory response during exercise-heat stress.
