Ergogenic Aids
A.3.1
What is an Ergogenic Aid?
Answer
“An ergogenic aid is any substance or phenomenon that improves an athlete’s
performance, especially by limiting fatigue symptoms”
2.
Doping Methods
Some athletes resort to illegal methods in order to maximize their performance;
to the extent, that not only are they disqualified from competing if found guilty,
but they put their lives at risk.
Two illegal methods of stimulating the effects of altitude training and
improving enduring performance are:
o Blood doping
o rEPO Recombinant Erythropoietin
How can blood doping and rEPO lead to an improvement in VO2 Max?
Past Exam Q: How can specific training increase an athlete’s VO2
Max?
Blood doping and rEPO lead to an improvement in VO2 max as they enable
the sportsperson to work at a higher rate for longer and therefore
considerably enhance aerobic performance due to:
o Increase Red Blood Cells - Increase in Haemoglobin - increase the VO2
max -increase oxygen uptake and carrying capacity – therefore increases
energy delivery to enhance aerobic performance

Erythropoietin (EPO)*
Erythropoietin (EPO)*
A hormone produced by the kidney that
promotes the formation of red blood
cells in the bone marrow – increase
haemoglobin levels.
EPO then stimulates the bone marrow
to produce more red cells and thereby
increase the oxygen-carrying capacity
of the body (blood) and can lead to an
increase in the amount of work
performed.
EPO has been much misused as a
performance-enhancing drug in
endurance athletes including some
cyclists (in the Tour de France), longdistance runners, speed skaters, and
Nordic (cross-country) skiers.
Dehydration can further increase the
viscosity of the blood, blood clotting,
increasing the risk for heart attacks
and strokes.

then compensates for this loss and
makes more red blood cells.

What do we mean by the Placebo effect?
Answer
A placebo is anything that seems to be a "real" medical treatment -- but isn't. It
could be a pill, a shot, or some other type of "fake" treatment. What all
placebos have in common is that they do not contain an active substance meant
to affect health.
How Are Placebos Used?
Researchers use placebos during studies to help them understand what effect a
new drug or some other treatment might have on a particular condition.
For instance, some people in a study might be given a new drug to lower
cholesterol. Others would get a placebo. None of the people in the study will
know if they got the real treatment or the placebo.
Researchers then compare the effects of the drug and the placebo on the
people in the study. That way, they can determine the effectiveness of the new
drug and check for side effects.
What Is the Placebo Effect?
Sometimes a person can have a response to a placebo. The response can be
positive or negative. For instance, the person's symptoms may improve. Or the
person may have what appears to be side effects from the treatment. These
responses are known as the "placebo effect."
There are some conditions in which a placebo can produce results even when
people know they are taking a placebo. Studies show that placebos can have an
effect on conditions such as:





Depression
Pain
Sleep disorders
Irritable bowel syndrome
Menopause
In one study involving asthma, people using a placebo inhaler did no better on
breathing tests than sitting and doing nothing. But when researchers asked for

people's perception of how they felt, the placebo inhaler was reported as being
as effective as medicine in providing relief.
How Does the Placebo Effect Work?
Research on the placebo effect has focused on the relationship of mind and
body. One of the most common theories is that the placebo effect is due to a
person's expectations. If a person expects a pill to do something, then it's
possible that the body's own chemistry can cause effects similar to what a
medication might have caused.
For instance, in one study, people were given a placebo and told it was a
stimulant. After taking the pill, their pulse rate sped up, their blood pressure
increased, and their reaction speeds improved. When people were given the
same pill and told it was to help them get to sleep, they experienced the
opposite effects.
Experts also say that there is a relationship between how strongly a person
expects to have results and whether or not results occur. The stronger the
feeling, the more likely it is that a person will experience positive effects. There
may be a profound effect due to the interaction between a patient and health
care provider.
