Serum erythropoietin of elite swimmers training at modrate altitude
The hormone erythropoietin (EPO), released under hypoxic conditions, acts to stimulate RBC production. Serum EPO, reticulocyte count (retic), haemoglobin concentration (Hb) and percent haemocrit (Het) were monitored in 6 male world-ranked swimmers during and following a 3-week training camp at 1850 m. Serum EPO and retics were significantly increased by day 19 and remained elevated 3 weeks postaltitude. The Hb values were raised by 5% at the end of the test period, and had retained this level 6 months later. There was a difference in the EPO response by sprinters and endurance specialists. Further work is required to elucidate the mechanism of EPO response and its effects upon performance.
