Veteran ![]() ![]() ![]() ![]() ![]() | ![]() I'm a big fan of trying to give blood at least twice a year (especially since i'm type O), but... I'm a little concerned about giving blood the week before my first half iron.... Has anyone done this before? If so, did you feel ok during your race? Considering I'll be doing a longer distance, any opinions on if I should just cancel the appt. to give? Thanks! |

Master ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() Why not reschedule for after the race? Then you can double up on the cookies, too. (: |

Expert![]() ![]() ![]() ![]() | ![]() I give blood as much as humanly possible, but, I would never donate that close to a race. I know that I've heard that you can be "back to normal" in as little as 36 hours, but I wouldn't trust that. It usually takes me a week to feel really good again. I know this is mostly a matter of personal experience so take it for what it's worth. I think you should cancel the appt. There are tons of blood drives listed on the blood donor website and you can probably find one for after the race pretty easily. |

Veteran ![]() ![]() ![]() ![]() ![]() | ![]() Thanks guys for the input--always helps to know other's experiences/opinions. The blood mobile comes around to our worksite every 4 months or so, so I guess I can just make an appt. the next time they are in the area. |

Master ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() I donate about 6 times per year. I take 24 hours off of training after giving a pint. I would allow a week to build back up to full blood supply for a Sprint, 2 weeks for an Oly and probably 3 weeks for a HIM. I would delay and donate the week after the HIM race. |

Master ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() I donate about 4x/year. The workouts in the next few days afterwards are usually a bit tough. If nothing else, my heartrate elevates ALOT. But I think I'm ok after those few days. However, there's no way I'd ever donate the week before a Half IM. I think I'd be more like a month, just to be sure. One theory of mine...I've given platelets a few times. I'm wondering if that might be a better option since you retain your red blood cells, which are the ones that carry oxygen. (Just don't crash and bleed.) Again...just a theory with absolutely no basis whatsoever. |

Elite![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() my wife is a phlebotomist and works for the Indiana Blood Center. She says that after a week you should be fine, but if you are concerned, not to push it. Most of the ill effects you feel right after donating are a reaction to the suddenly lower blood volume (hypovolemia). Low blood volume = lower blood pressure = floor for some people. Last time I gave whole blood, I made sure I ate well and stayed hydrated before and after, and only felt weakened for a day. I was back to training at normal levels 2 days afterward. Platelets would be a better option if you have the extra time, as it does give you back your red cells. However, it still dehydrates you, so you will need to make sure you really focus on staying hydrated before and after. One thing to consider as well... Mobile people tend to try and rush through the process, to get people in and out. So if you have issues with them missing your veins, just find a center and go donate on your lunch break (some companies will let you donate on the clock...worth looking into). |

Expert ![]() ![]() ![]() ![]() ![]() ![]() | ![]() I donate regularly too. We Oneg's have to look out for eachother I agree that you might as well wait until after the race since it is so close. It probably wouldnt make too much of a difference, but waiting a week or two to donate probably wont either. Good luck |

Champion ![]() ![]() ![]() ![]() | ![]() Don't do it. Don't even consider doing it. Make an appointment for the next time it comes around. |

Member ![]() ![]() | ![]() I donated three days before a marathon this year and went on to a PR. I just made sure to drink plenty of fluids and eat healthy meals afterward. Your plasma will be back to normal in a couple days, but the RBC's take over a month. You should still have plenty to stay perfectly oxygenated, unless you have low hemoglobin to begin with. I've always wanted to donate right after a race just to hear the phone call afterward. "Uh, you might want to see a doctor as soon as possible." Hehe. |

Member ![]() | ![]() Giving blood won't affect your performance. Your cardiovascular system isn't going to be a limiter for you anyways. If someone was going to DNF, it would be from local muscle fatigue before there was a problem carrying oxygen to tissues(barring any catastrophy). I think you'd be fine except it might psych you out just KNOWING that you gave blood. Like other people have said though, the blood center will be there after the race. |

Expert ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() I wish I could....this rule hits me though: You were a member of the of the U.S. military, a civilian military employee, or a dependent of a member of the U.S. military who spent a total time of 6 months on or associated with a military base in any of the following areas during the specified time frames
The rule concerns Mad Cow Disease; I'm just wondering if there is ever an expiration on this. I was there from 1989 - 1995, but if CDJ was to happen, I'd think it'd have happened by now. |

I think you'd be fine except it might psych you out just KNOWING that you gave blood. Like other people have said though, the blood center will be there after the race. That's not correct. Delivery of oxygen to tissues is directly related to hemoglobin levels. When you artificially suppress those levels by donating, you're limiting the oxygen delivery capacity of your body, and you will see performance affected. It's the opposite of taking EPO, where you artificially raise your hemoglobin levels and see increased endurance performance. |

I think you'd be fine except it might psych you out just KNOWING that you gave blood. Like other people have said though, the blood center will be there after the race. That is not true. When you donate you blood, you are losing close to 10% of your red blood cells and it can take well over a week to reproduce them. http://www3.interscience.wiley.com/journal/120121344/abstract?CRETRY=1&SRETRY=0 I'm not paying to read that entire study, but the results portion of the abstract say the average time it took to recover hemoglobin levels was 36 days, with a range of 11 either way. An Ask the Doctor from velonews: http://velonews.com/article/5265 In the best study I found on this topic, a group of researchers took10 male "amateur competitive cyclists" and measured heart rate (HR), VO2max, power output (in watts), and ventilatory threshold (VTh) during a standardized incremental exercise study. They tested each cyclist at four time points relating to a blood donation: One week before; two hours after; two days after, and seven days after. These researchers found that at maximal efforts all performance measurements were adversely affected at all three post-donation time points. For example, at the two hours and the two days testing, VO2max was down about eight percent. Even at seven days post-donation, the average VO2max was only improved to about seven percent down from pre-donation baseline testing.

Master ![]() ![]() ![]() ![]() ![]() | ![]() Call 1-800-Give-Life and schedule your appointment for a more convenient time. They will be very nice about rescheduling you. I have done this before when I got sick or there was a virus in my house. I'm on "the list" at the Red Cross now and they call me whenever I'm eligible to donate again but last time I told them that I'm out until after my HIM race. |

Champion ![]() ![]() ![]() ![]() ![]() ![]() ![]() | ![]() After. My doctor suggested I not donate blood the time prior to my backpacking trip (about 6 weeks). I'd treat the HIM the same way. |

Regular![]() ![]() ![]() | ![]() MikeJ - 2008-08-20 9:13 AM I donate regularly too. We Oneg's have to look out for eachother I agree that you might as well wait until after the race since it is so close. It probably wouldnt make too much of a difference, but waiting a week or two to donate probably wont either. Good luck Every eight weeks like clock-work. Heck, I make my next appointment before I leave the center. Not only am I O- but am also eligible to donate for neonatal so my blood's in serious demand. That said, I also would probably give it a week or so but then I'm nowhere near HIM level. |

Expert![]() ![]() ![]() ![]() ![]() ![]() | ![]() Similar story to many above -- back when I donated, running the next few days was sometimes tougher than usual. Other than that, no serious issues. I wouldn't donate less than a few weeks out from a race. I can't donate any more since I have traveled (and continue to travel) to places that are on the 'banned' list for blood donors.
