I have foolishly gone riding and played five-a-side after giving blood without thinking about it. Certainly felt pretty wonky (lightheaded and running on empty) on both occasions with 400 ml or so less blood so I wouldn’t be surprised if a few ‘medium tubes’ made a difference.
As a safety measure I now skip straight to the wine after giving blood and have a couple of days break before going back to strenuous exercise.Posted 4 years agotrailofdestructionMember
I’m a regular blood donor, so lose about a pint a time. Went out for a big ride on the Sunday, after donating on the Friday night. Big mistake, felt absolutely terrible, almost puked on the last hill, felt dizzy and weak like when I first started riding, and my lungs and heart wanted to jump out my throat.
Then I remembered, after talking to the nurse on a previous visit about how long it can take for the body to replace that much blood, that it can take up to 2 weeks. Lesson learned, so I try no to push myself to hard after losing that much blood, and let my body do it’s thang, and top itself up before I start going for it again.

I had some blood tests yesterday, as I’m knocking 40 (routine apparently!) they didn’t take out all that much, a few medium sized tubes.
I jumped on my trainer today to do some exercise after work (I live in nz, so winter, dark, cold and wet) and I was doing intervals, 5 mins, 10 mins off 5 mins on etc. I started breathing a bit irregular on the first interval. On the second interval felt like I was having an astma attack so I stopped and did the sensible thing and opened a bottle of wine instead.
Does taking out a little bit of blood make that much difference? I know adding it is all the rage with the sky team, but how much do you have to take out before you are weak as a kitten?Posted 4 years ago
