Ra. Panebianco et al., EFFECTS OF BLOOD DONATION ON EXERCISE PERFORMANCE IN COMPETITIVE CYCLISTS, The American heart journal, 130(4), 1995, pp. 838-840
This study evaluated 10 male cyclists before and after phlebotomy to d
etermine the effect of donation of 1 U of blood on exercise performanc
e. Each subject underwent maximal exercise testing with oxygen consump
tion measurement at baseline, 2 hours after phlebotomy, 2 days after p
hlebotomy, and 7 days after phlebotomy. Maximal performance was decrea
sed for at least 1 week. Submaximal performance was unaffected by bloo
d donation.
