Recovering from blood donation

#21

How long should I wait before retiring to normal training post giving blood ? 24 hours ?

Give it a day or two, and expect to have trouble sustaining your previous efforts for a few weeks after that as blood plasma volume and red blood cell count rebuild.

I don’t wait at all. I’ve gone mountain biking the same day, with no intention of taking it easy. I didn’t notice anything. I asked the nurse for her thoughts on exercising after giving blood while she was drawing the blood and she said there shouldn’t be any reason why I shouldn’t. But I don’t think this was her area of expertise.

**big update. I was not donating blood! It was just for a blood test. Nowhere near the amount drawn for a donation.

I donated platelets this afternoon (double donation as normal) tomorrow I have 1h30m of Tunemah, with Glassy on Sunday.

What are the thoughts on maybe dropping the intensity to 95%?

It seems to be a very personal thing. I know from past experience that I simply can’t do over/unders for several days after giving. I suppose you won’t know unless you try. I’d start @ 95% and see what you feel like.

That’s what I’m thinking tbh… I’m fairly new to training with power, so it’s gonna be a leap of faith on the mighty Kickr Snap tomorrow…

I’d suggest you try at 100% and see how it goes - it’s mentally easier to drop the difficulty to 95% if you’re failing at 100% than it is to increase it to 100% from 95%

You feel better when you put the blood bag in, not take it out :wink:

To update this - I set off on Reinstein this morning and couldn’t even finish the first 12min set of over and unders at 100%, so dropped it to 95% and then 90%, before ending it at the end of the first 12min set, and swapping to Carter.

I won’t be trying that again…

Hard lesson learned. As mentioned, it is probably best to keep it very easy for days after the donation.

Yup - it’s now noted, but as ever, Reading something and failing miserably because you didn’t take the info on board are two different things… :man_shrugging:t2::joy:

LOL, hard learned lessons are often the ones that stick. Glad you have it sorted.

For those interested in the discussion on blood donation, it starts at about 1:08:30.

Thanks for sharing, I was hoping to find exactly what this thread discussed, after struggling through what should’ve been a manageable workout 4 days after a double platelet donation.

Some reference info, just for the sake of curiosity.

Prior Ramp Test on Tuesday, Feb 12, 2019 at 6:26 PM

  • 250w
  • Notes: 250w, H2 in 34 & mid of 11-28. Went ok, and legs seemed working harder than cardio.
  • Then I proceeded to do the final 3 “work” weeks of Sweet Spot Base 2, Mid Vol and added some runs. I felt like I was gaining in strength/fitness and may well have increased FTP, but did not test.

I did a whole blood donation on Sunday, Mar 3, 2019 after completing the final workout in the “work” week.

  • I took the 250W FTP that I had trained at for the prior 3 weeks and lowered it manually 10% to get 225w.
  • I did a couple of recovery workouts that felt really easy, and looked so when comparing RPE and HR to similar workouts the prior month.
  • I adjusted my FTP to 235w for the remainder of the recovery week workouts.
  • That felt about right for the last workouts and being at the end of a recovery week.

I did a new Ramp Test last night, Tuesday, Mar 12, 2019 at 6:26 PM

  • 237w
  • Notes: Legs and lungs about even on this one. Surprised at the relatively low HR on this one. But that could be the price of the blood donation?

With or without the potential increase in FTP that I may have gotten in the 3 weeks of work, that amounts to:

  • 237w / 250w = 0.948
    • Which is 94.8%, or a 5.2% reduction in FTP from my whole blood donation.
  • 237w / 255w = 0.929
    • Which is 92.9%, or a 7.1% reduction in FTP from my whole blood donation (from an estimated 2% FTP increase during the 3 work weeks).

Overall, interesting but not conclusive. It surely shows the effects of a whole blood donation being detrimental to my strength/power/endurance. I can use this to guess a bit closer on how much to reduce in the future. I can probably consider 5-7% (6% as an average) planned FTP adjustments as I go forward.

I’d love to not lose this much, but it’s part of my treatments and a positive benefit to some individuals, so it is well worth it in the end. But the reset that I get about even 17 weeks is still a bit of a pill to swallow. Hopefully I can return to the prior power in the next few weeks and be ready for my first race in about 8 weeks.


Edit: And now the crazy concidence… I just received a text message from my blood bank, that my donation is headed to a patient for a transfusion right now.

  • There’s the best reason to suck it up and live with the drop in fitness. Best wishes to whomever is in need. It’s a good reminder to have. Thanks, Vitalant. :smiley:
