Giving Blood?? How much of a negative effect on performance??
I like to regularly give blood, however I was advised against it while training over the summer for my first Tri. Now I’m into the winter training and I don’t have any serious competitions in the next 3 months (just X-country league with my running club) can I give blood without it seriously effecting my performance/training?? I have a theory... If I give blood and continue with the same amount of exercise, my body has to work harder and more efficiently to cope and therefore this makes me fitter in the long run. Although my performance may actually decrease in the short term... Does anyone have any thoughts?
