"A study has been done looking at the effects of blood donation on exercise performance in competitive cyclists. This study evaluated 10 male cyclists before and after phlebotomy (donating blood), to determine the effect of donation of one unit of blood on exercise performance. Each subject underwent maximal exercise testing with oxygen consumption measurement at baseline, 2 hours after phlebotomy, 2 days after phlebotomy, and 7 days after phlebotomy. The results found that maximal performance was decreased for at least one week and that submaximal performance was unaffected by blood donation.

Thus, if you are a competitive cyclist, do not donate blood within 7 – 10 days of a competitive race, as your performance will be compromised. If you are a casual cyclist performing submaximally, you may not experience any deleterious effects apart from a higher heart rate than normal from the day after donating."

What are the effects of donating blood on scuba diving?

"For the first few hours/days after donating blood, the person will be more susceptible to fainting and will have a reduced exercise capacity. After the blood volume that was lost in the donation is replaced, the person will no longer be prone to fainting and might actually have a slightly improved exercise capacity. There are theoretical slight increases in the risk of oxygen toxicity and DCS but this change in risk most likely has no practical significance. You should never dive (nor do other strenuous activity) the day of a blood donation and should be sure to drink lots of nonalcoholic fluids after donating blood. It should be okay to do conservative dives the next day but if you want to be absolutely certain you have recovered from the acute effects of donating blood, wait 72 hours."
