WADA President Richard Pound recently commented on 'blood spinning', the technique of removing platelets from the blood (the cells that assist the process of healing) and reinjecting them into an injured part of the body to speed up the process of recovery. The English football team Chelsea is using this practice, but it seems likely that they will for much longer. UK Sport has already raised questions about whether it should be considered a form of doping. Yet, it is precisely this kind of application that is tricky for WADA and for the medical profession. Certainly, it could be construed as the application of a medical intervention for a performance purpose, but this purpose is perhaps not obvious, nor can it be taken in isolation, since the technique promotes recovery.
Quoted in AFP: "It sounds like blood manipulation of some sort to me. But I would need to talk to our scientific department to get all the background," said Richard Pound."
