I will say this, the other day I donated blood like I often do. It was very early int he morning before work and after I ate and worked for about 9 hours. Then I went home and ate again, rested a little and about 7:30 went to the gym.
My wife told me I should have stayed home but I felt fine. I didn't feel weak or anything so I went to train like I always do on those days.
After initial warm ups and some bag work, I had to stop. I got light headed and got very weak. I know it was the blood taken out and it was weird how it affected me that way.
I ended up cutting the work out short and going home. Blood can take a lot out of you, then again it was the same day and the next day I was fine.
