Extreme Veteran 494 Horse Country | Subject: RE: Donating Blood Well, I can't quote any papers or anything, but I'm quite sure it does... but how much depends on the amount and type of the donation. A standard donation means you're going to be a pint low on your red blood cells, and those would be the ones you need to transport oxygen to your muscles. They take weeks to replace, so your performance will suffer until they are replaced. Do a Google on autologous (sp?) blood doping (see Tyler Hamilton case) for more info... ie.. the problem with this type of doping is that you have to remove the blood at some point in your training, and take the training hit while you recover, so that you can "dope" with it later... A plasma donation might not hurt as much, as its pretty much all fluids, and you can replace that in a few days by hydrating well... A double RBC, pheresis, or other such "advanced" donation, will of course be that much more of a hit. Of course, with a double RBC, you can only go back every 112 days instead of every 56 days. So while it's twice as bad at the time, you only do it half as often. If you're just training, it's probably not going to hurt too much... it'll just force your body to compensate to one more stressor (it might have an effect analogous to high-altitude training). But donating within a few weeks before a key race would be a good way to hurt your race day performance. As for me, I just try to schedule my donations for just AFTER my key races. This info is from a total layman (and almost 2 gallon donor) and is worth every penny you paid for it... Edited by BGTwinDad 2005-05-23 10:26 AM |

Extreme Veteran 586 Waterboro, Maine | Subject: RE: Donating Blood I agree with the impact of donating blood. It probably won't set you back during training phase, as long as you take it easy. I attempted to donate during training, and was refused because I was anaemic. Training stresses the body and I couldn't keep up with my iron needs. I am grateful that I found out about the anaemia. It explained a lot of things - like the tiredness, the night leg cramps, etc. - Maureen |

Expert 743 Olney, MD | Subject: RE: Donating Blood Give blood! I work at the Red Cross. If you have a race coming up in the next week, don't. But if you have a couple/few weeks before your next race, your body will be up to speed in plenty of time. I'd take off the day of donating and take the next day off or have an easier than normal workout. |

Elite 3235 San Diego | Subject: RE: Donating Blood I would say donate, unless you have a race coming up. I donated during my IM training and I felt like crap for a couple of weeks. It was my first time donating and didn't know what to expect. My HR was higher than before and I felt like I had less energy for about 2 weeks, but after that I felt great and I didn't feel it effected my race at all. I will donate again, for sure. |

Expert 1166 Colchester, CT | Subject: RE: Donating Blood Generally it takes me a couple of weeks to get back up to speed after donating blood. Usually I'll just slow my pace down for those two weeks, but keep the same volume. And another thing, I hydrate like mad, seems to help in the recovery Chris |

Elite 2527 Armpit of Ontario | Subject: RE: Donating Blood I was a regular donator up until a year ago when a health crisis followed by long-term preventative medication disqualified me from every giving again. My experience was that it had miniaml effects on training. I was a little lethargic for a couple of days, taking only the day-of-donating off (to reduce the risk of bleeding) and then just reduced volume for a couple days, then right back to normal. I made sure to hydrate well for a few days, taking in a little more than usual, but nothing dramatic.

Expert 704 The High Plains | Subject: RE: Donating Blood Give blood -- play Rugby! I donate (A+) as often as I can (every 56 days, I think) and I normally feel nothing when it comes to being active. The only time I felt a little off after I donated was when I was also on a calorie restricted diet (see weight loss), but my job has me on my feet all day every day, so I was functioning on fewer calories and I was down a pint of blood. I donated last Tuesday afternoon, ran my normal 6 miler on Wednesday, went to bed early, did a short bike ride on Thursday, long run on Friday, and felt no ill effects of having donated. As has already been stated, I wouldn't donate immediately before a race, but a few weeks out won't be so bad. Donating blood is a good thing. If you can do it, the Red Cross can use your help. SR |

Expert 1065 Montreal | Subject: RE: Donating Blood I donate whenever I can - but wouldn't do it within a week of a major race. The recovery time for losing a pint of blood isn't that long. If you are really worried about the effect give blood after a work out the day before a rest day and then do two light workout following. |

Extreme Veteran 494 Horse Country | Subject: RE: Donating Blood Amen to this. My wife needed 7 pints for our twins' delivery, and one of the kids needed 1/4 pint as well. We've already given this much and more since then, but we'll never truly repay the debt. Were it not for the donors of those seven pints, I'd be a widower right now, and possibly childless as well. I never donated till the kids were born, since then I've given nearly two gallons and am due for a donation now. Thanks everyone who has ever donated. |

Member 44 | Subject: RE: Donating Blood Since returning from Desert Storm in 91’ I was told I could no longer donate blood. Up until then I would donate regularly. Does anyone know if this has changed? |

Elite 2527 Armpit of Ontario | Subject: RE: Donating Blood Contact your local Blood Services collection agency (Red Cross, Canadian Blood Services, etc) and they will tell you if you qualify. I want to chime in about the importance for everyone to make an attempt to donate as often as possible. My wife was T-Boned in 94 by a driver on his cell phone doing 160km+ and she was airlifted to a major hospital centre for emergency surgery due to massive internal hemmoraging. They exhausted the supply of blood products at the University hospital and had to send ambulances out on runs and eventually exhausted the supply at every other medical centre in the area just to keep up with her blood loss - a total of 55 units of blood & blood products saved her life. All of this blood came from donations. Ever since then I made a committment to donate as often as I was able, until last year when I became permanently disqualified. Please give. Save a life. |
