I gave blood on Thursday and did my usual trick of almost fainting afterwards, opps. Anyway I went for a run this morning and predictably it felt harder than normal.
I was wondering if anyone out there knows if there is any advantage in training when our red blood cells might be slightly depleted? Any does anyone know how long it takes to get back to normal?
I ran after donating for the first time a couple of weeks ago. Strange experience as everything felt "normal" except the laboured breathing. Physiologically it takes about 6 weeks to get back close to normal in tests, but I'm guessing it wouldn't make much noticable difference after 3-4 unless maybe you raced in peak condition.
I haven't seen any research on the different response of athletes to the general population in recovery after donation, but I'm sure some work has been done.
I've been doing a bit of Googling on this lately and I can't find anything credible that says there are benefits to training when down on red blood cells.
I gave blood 1.5 weeks ago and my running is still shot - what was my easy pace now feels very laboured. I'm hoping it's not actually another 2-3 weeks of this.
So do I Weeble. I'm just waiting for a break on the weather to head out today. I'm really hoping it will be a little easier than on Saturday.
My mum feels really energised after giving blood and has the opposite feeling. She runs better after giving blood than before!
I have no idea, she's always been like that. When I was younger she used to describe giving blood as: "getting rid of the old to make way for the new" and she used to be really energetic afterwards (which had the effect that she had trouble sleeping for a while!). They still accept her for blood donations so it cant be too bad. In comparison, my sister is knocked sideways when she gives blood so that doesnt run in the family!
She's a plodder (she's nearly 60 so doesnt really "run" anymore) and she has run PB's on all of her races after giving blood a few days beforehand (she calls it her secret weapon!).
Running Rodent - I'm not a medic but I am married to one. She reckons that it won't have much effect on the blood donating after a marathon, though it will be higher in muscle breakdown products. However you should not be donating right after stressing your body in that way as it will affect the recovery. A week later should be fine.
I received a questionaire from the Blood Transfusion Service (who are always trying to get hold of my O -ve blood) to ask why I'd not donated since last winter. So I told them it had to fit into a racing schedule which probably sounds OK to all of us and very selfish to the general public!
Gave blood a couple of hours after a heavy hill session once, did not feel good after. Then again I never do, nearly always end up with my legs in the air trying not to be sick.
I'm thinking of fitting my next donation into a steady period of training (so that I'm running pretty much the same week in week out) so it might be interesting to compare times over that.
That would be interesting to compare your times and how difficult you find your runs.
