Summary

This study looked at whether giving healthy volunteers a small amount of their own stored blood (200 ml) causes detectable changes in blood cells and particles. Researchers analyzed blood samples before and after transfusion to find markers that could reveal this type of doping in athletes. The study involved 28 healthy men aged 18-35 and did not aim to treat any disease.
