IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids 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 IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids A.3.3 , A.3.5 & A.3.6 Very Brief Doping Classes DRUG DESCRIPTION and outline the actual benefits some athletes would hope to gain Artificially produced hormones Liver damage, acne, excessive aggression Promote muscle growth and lean body weight Testosterone Testosterone DRUG Harmful effects of long term use s and related substanc es (Human growth hormone (testoster one) insulin) anabolic steroids* Very Important maintaining muscle mass, bone density, levels of red blood cells, and a general sense of vigor and well-being. Cardiac risk factors Hypertension Liver damage High blood pressure- stroke DESCRIPTION and outline the Harmful effects of long term actual benefits some athletes use would hope to gain 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. IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids Human Growth Hormone – (HGH) Human Growth Hormone – (HGH) It is produced by the pituitary gland and is essential for normal growth and development. hGH is The side-effects of hGH are vast and anabolic, meaning it accelerates some serious: here are some; protein synthesis and also aids Gigantism in younger athletes the metabolism (breaking down) (or pituitary gigantism or of fat stores. giantism.

The stored blood is then injected back into the performer, giving them a higher red blood count To improve aerobic capacity through increasing the oxygen carrying capacity of the body, allowing the performer to work for longer and therefore considerably enhance aerobic performance due to: The viscosity of the blood could increase, leading to clotting and a risk of death IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids - 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 Stimulants is a name given to several groups of drugs that tend to increase alertness and physical processes in the body. Stimulants* Caffeine (important) increase danger of dehydration Legal stimulants include: caffeine* nicotine Caffeine thought to improve the mobilisation of fatty acids in the body. Illegal stimulants include: Amphetamines cocaine and crack Performance enhancing drugs are taken by sports performers specifically to improve their performance. Social drugs are controlled usually taken to heighten feelings or emotions Alcohol Tobacco Drugs - IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids Match the following terms with the correct description below: Nutritional Ergogenic Aids Non-Nutritional Ergogenic Aids Pharmalogical Aids Mechanical Aids Physiological Aids Psychological Aids Nutritional Ergogenic Aids Categories and Examples of Ergogenic Aids Refers to substances that enhance performance (either by affecting energy metabolism or by an effect on the central nervous system), at increasing lean body mass or muscle mass by reducing fat content. Non-Nutritional Ergogenic Aids Pharmalogical Aids Carbohydrate loading, sports drinks, caffeine intake and the consumption of other substances commonly available in food supply (creatine, protein powders, and amino acid powders) Anabolic steroids, hormones and related substances, diuretics and masking agents, beta blockers and stimulants Anabolic steroids (includes testosterone), high dose nutrient supplements (vitamins and minerals). Pharmacological effect – beyond the nutritional effect you would expect from a normal intake.

IB Sports, Exercise and Health Science A.3.2 Option A.3: Non-nutritional ergogenic aids 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 IB Sports, Exercise and Health Science Option A.3: Non-nutritional ergogenic aids 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. http://www.webmd.com/pain-management/what-is-the-placebo-effect Give an example of a reported placebo effect associated with a specific ergogenic aid in the sport of your choice.
