Detecting blood doping

I have a question regarding blood doping that I was hoping you could answer.

If riders dope by extracting and storing their own blood, to be used at a later date in competition to boost oxygen carrying capacity to the muscles, how can this be detected? I understand that the testing procedures can pick up someone else's blood, as with Vino, but what if he had used his own blood? Will the new 'biological passport' that's been talked up at the moment be able to be used to detect this form of doping?

I have read that riders can have up to a 30% advantage with the extra blood in their system - is this true?


Scott Saifer replies:

I'm not an expert on this but here's my very rough understanding. Red blood cells develop signs of age as they circulate. One sign I remember is that bits of cell membrane get shredded off and the remaining membrane then re-closes. That means that the initially floppy disk becomes gradually more spherical and less flexible. This particular sign is not so important as the fact that the ages of the cells in a sample can be measured.

Now, when a rider makes a donation (has blood taken out), the kidneys respond to the decreased oxygen carrying capacity of the remaining blood by producing a burst of EPO which triggers a burst of red-cell production in the bone marrow. Some time later, a bunch of new red cells appear in the blood, an excess of cells of exactly the same age. That's not how the rider gets in trouble of course since donating blood is legal.

When the cells are put back in, the kidneys recognize that oxygen carrying capacity is more than adequate and shut down EPO release. The marrow stops making new red cells for a while, with the result that there will be an absence of new cells of a particular age.

The method of identifying riders who have doped with their own blood, as I understand it, involves looking for these odd spikes and valleys in the distribution or red-cell ages. I'm not sure what a 30% advantage looks like, but if the measure is VO2-max or power at lactate threshold, 30% sounds too high to me.

Cycling with celiac disease

I'm an avid cyclist, male, 38years old. I compete in several races (MTB and road) every year, and have another 24 hour MTB race coming up soon. I was recently diagnosed with celiac disease, although I have no outward symptoms. Blood work shows that I have been anaemic and low iron/ferritin, with decreased bone density.

My question is: how will this affect my performance during the 24 hour races if I can't eat pastas or bread? There are alternatives out there, but will they have the same desired effect as getting carbohydrates from pasta and bread?

I usually use a lot of Hammer mixes and gels during the race and was pleased to find they contain no gluten. Will this be enough?

Phoenix, Arizona, USA

Scott Saifer replies:

It is possible to race really well while avoiding the gluten-containing items that trigger the celiac disease. It can take some time to figure out foods that work for you, but there are plenty of choices. As you noted, Hammer products are safe for you, but you don't have to rely on highly refined industrial foods at all. I don't have celiac but often use a lot of potatoes and yams as training and racing food.

The bigger and more immediate question is how you can perform with anaemia. That will take some time to correct, and you can't really perform well until your hematocrit is at least normal.

Combating fatigue

I'm a 32 year-old female, height 160cm, weight 57kg. I'm a mountain biker and also commute to work, 17km each way, four days a week. In the last two weeks I have noticed a considerable difference in my riding. I am now finding that I am struggling on my commute.

I have a 50km race coming up and am need to continue training. Can you please advise how to combat cycling fatigue, yet continue with training or is it a matter of rest? I have just started differing my lengths on my commute to change things up.

Fatigued cyclist

Scott Saifer replies:

There are several sources of fatigue and different appropriate treatments. You can get yourself fatigued by riding too hard, too much of the time. A heart rate monitor is handy for preventing this. A standard prescription would be to keep your heart rate under 70% of your individually determined maximum until the fatigue clears (220-age and other formulas are not accurate enough to be useful for competitive athletes) and then keep your heart rate under 80% of maximum on all but one or two days per week.

You can get fatigued by chronically under-eating carbohydrate or calories. This is particularly common in riders who are currently getting stronger as calorific needs increase with exercise power output. Make a point of eating about 60g of carbohydrate per hour of riding, divided in 3-4 chunks, one every 15-20 minutes. Have a carbohydrate rich snack immediately after any ride. If you are concerned about daily calorie consumption, cut them out elsewhere in your day, but not on the bike or just after riding.

There are many other causes of fatigue that are relatively easy to cure: Under eating salt can leave people feeling worn out and also cramping. Cyclists who train in sweaty climates need a lot of salt, like a good shake on most every meal (if you have personal or family history of high blood pressure, check with your doctor first). Under sleeping leaves you tired of course, and athletes usually need a bit more sleep, perhaps an hour per day, than the non-athletes they used to be. If none of these suggestions seem to match your situation, please write again.

Determining potential

I have a question about predicting potential from an anaerobic threshold test. I recently did a test using the Conconi method.

The results were that my threshold is 285 Watts at 180 bpm with max hear rate at 197. I am 33 years old, 5'11" and in race season about 175 lbs looking to be around 170 lbs for this season. I have been riding road for three years and last season was my first full season racing.

I was wondering if there is a way to figure out your potential from a test? I have heard that having a fairly high heart rate means you have a small heart or "small engine". I tend to be a sprinter type but really enjoy time trials and would like to do well at them. Does the fact that I have a fairly high heart rate mean time trials are probably not going to be a strength?

Ontario, Canada

Scott Saifer replies:

Your heart rate at the Conconi measured AT by itself tells you nothing at all about your potential as a bike racer. Two riders with ATs of 140 and 190 bpm could have identical competitive ability in identical races. Your power at AT, assuming you are well trained currently, tells you a lot more. Your power of 258 is not particularly high for someone your size. Unless you can boost that a good bit, time trials are not going to be a strength
