Supplementation
<strong>In</strong>troduction<br />
اکثر مصرف کنندگان بر این باورند که مکمل ها نقش کلیدی و<br />
اصلی را در موفقیت ورزشکاران ، چه در تمرینات و چه در<br />
بازگشت به حال اولیه و چه در مسابقات ایفا می کنند.<br />
بسیاری از محققین و مراجع ذیصالح علمی نشان داده اند که<br />
در بسیاری از مکمل ها بین آنچه واقعا در ترکیبات آنها است و<br />
آنچه بر روی برچسب آنها ذکر شده است تفاوت وجود دارد.<br />
•<br />

از مکمل های پروتئینی چنین<br />
وضعیتی را دارند.
<strong>In</strong>troduction<br />
مواد اصلی که عموما آلودگی مكمل های پروتئینی با آنها صورت گرفنه<br />
است عبارتند از:<br />
• stimulants (i.e. ephedrine )<br />
• anabolic androgenic steroids<br />
(i.e. testosterone, nandrolone)<br />
• AAS precursors, so-called prohormones<br />
androstenedione, norandrostenedione)<br />
• all of which are on the World Anti Doping Agency’s<br />
(WADA) list of forbidden substances.<br />

• <strong>The</strong>se results are extremely important for those athletes<br />
who are subject to in- or out-of-competition antidoping<br />

•<br />
از چند ديدگاه قابل بررسی است:<br />
طبقه بندی<br />
• Classification<br />
•<br />
مكمل های آلوده به مواد ممنوعه<br />
• Supplement contamination with doping substances<br />
تضمین کیفیت در تولید مكمل ها<br />
• Quality assurance in the production of supplements<br />
آيا مصرف مكمل موجب تمايل و گرايش به دوپینگ می شود؟<br />
• Does the use of supplements promote a doping<br />
attitude?

Protein<br />
• Proteins are essential to the structure and function of<br />
all living things.<br />
• Made of strings of amino acids linked with peptide<br />
bonds.<br />
• From just 21 amino acids, millions of different proteins<br />
may be created.<br />
• Amino acid basic structure:<br />
R-CH(NH 2 )-COOH
Amino Acids<br />
• Essential amino acids (8):<br />
• Isoleucine, leucine, lysine, methionine,<br />
phenylalanine, threonine, tryptophan, valine.<br />
• Non-essential amino acids (9):<br />
• Alanine,arginine, aspartic acid, glutamine, glutamic<br />
acid, hydroxyproline, ornithine, proline, serine.
Semi-essential<br />
amino acids
Semi-essential amino acids<br />
• Histidine (essential in children)<br />
• Glycine (essential in rapid growth)<br />
• Cysteine (essential if methionine is limited)<br />
• Tyrosine (essential if phenylalanine is limited)
Proteins in the body<br />
• Hormones (e.g. insulin, thyroxine)<br />
• All enzymes<br />
• Structural (e.g. collagen, keratin, fibrin)<br />
• Muscle protein (actin and myosin)
Protein turnover<br />
• Approximately 2 % of total body protein is<br />
broken down and re-synthesised each day.<br />
• As protein is broken down, some nitrogen is lost<br />
in the urine. <strong>The</strong> obligatory nitrogen loss in the<br />
urine reflects the minimum protein intake<br />
(adjusted for bioavailability) for a healthy adult.
Protein Quality<br />
Chemical analysis of the amino acids<br />
• Amount of each essential amino acid per 100 g of test<br />
protein compared with that of the same amino acid in<br />
100 g of hen’s egg protein.<br />
• <strong>The</strong> amino acid with the lowest value is termed the<br />
LIMITING AMINO ACID.<br />
• <strong>The</strong> AMINO ACID SCORE of a protein is the value<br />
of the limiting amino acid expressed as a percentage<br />
of the same amino acid in hen’s egg protein.
Protein Quality<br />
Biological Analysis<br />
• This is a measure of protein utilisation in<br />
growing children or rats.<br />
• Net Protein Utilisation (NPU) = (Nitrogen<br />
Retained in the Body/Nitrogen in the diet) x<br />

MRP
MRP 1<br />
• An MRP is also known as a meal replacement. An MRP is for<br />
exactly what it sounds; it is used to replace a meal.<br />
• Meal replacements are designed to give the proper amount of<br />
calories, amino acids, proteins, carbohydrate, etc; without most<br />
of the “bad” stuff we find in many quick meals. MRP’s are made<br />
to be very convenient and fast and are found in a variety of ways.<br />
• You can find meal replacement in:<br />
• Powders<br />
• Bar<br />
• Pre-Made Drink<br />
• Or Even Pastes

• Caffeine is 99% orally bioavailable.<br />
• Levels tend to peak within 30-60 minutes.<br />
• passing through all biological membranes including the<br />
blood brain barrier.<br />
• <strong>The</strong> half-life is around 5 hours.<br />
• 80% of caffeine is metabolized to paraxanthine by<br />
CYP1A2.<br />
• Several direct pharmacological effects include<br />
• adenosine receptor antagonism,<br />
• release of intracellular calcium,<br />
• phosphodiesterase inhibition,<br />
• and GABA receptor antagonism.

Green Tea 3<br />
• You can find green tea in several different ways.<br />
• You may find them in capsule or tablet form as a supplement, in<br />
tea form to be enjoyed as a drink, or even in leaf form to be used<br />
topically for sunburns or pain.<br />
• <strong>The</strong> recommended dose for the tablet or capsule form should be<br />
around 300-600mg daily before or with meals.<br />
• If you are going to enjoy green tea, as a tea, it is recommended that<br />
you use 1 teaspoon of tea leaves with 1cup of boiling water three<br />
times daily with or before meals.<br />
• Green Tea does contain caffeine and should be avoided directly<br />
before bedtime to prevent insomnia.
<strong>The</strong> Benefits <strong>Of</strong> Green Tea I<br />
• Tannins - A group of simple and complex<br />
phenol, polyphenol, and flavonoid<br />
compounds.<br />
• Green tea after a meal can aid in digestion
Other Benefits <strong>Of</strong> Green Tea I<br />
• Catechins - Catechins are a category of<br />
polyphenols.<br />
• <strong>In</strong> green tea, catechins are present in<br />
significant quantities, more specifically;<br />
• epicatechin (EC),<br />
• epigallocatechin (EGC),<br />
• epicatechin gallate (ECG)<br />
• and epigallocatechin gallate (EGCG).
Other Benefits <strong>Of</strong> Green Tea II<br />
• A cup of green tea may provide 10-40mg of<br />
polyphenols.<br />
• Green tea extracts rich in EGCG<br />
(epigallocatechin gallate) are thought to increase<br />
fat metabolism.<br />
• EGCG makes up about 10-50% of the total<br />
catechin content and appears to be the most<br />
powerful of the catechins - with antioxidant<br />
activity about 25-100 times more potent than<br />
vitamins C and E.
Other Benefits <strong>Of</strong> Green Tea III<br />
• Flavonoids - Flavonoids are plant pigments,<br />
and are found in most fresh fruits and<br />
vegetables.<br />
• <strong>The</strong>y may aid in protecting against infection.<br />
Deficiency can result in a tendency to bruise<br />
easily.
Other Benefits <strong>Of</strong> Green Tea IV<br />
• <strong>The</strong>anine - theanine is a unique amino acid<br />
found in the leaves sencha.<br />
• <strong>The</strong>anine is quite different from the polyphenol<br />
and catechin antioxidants for which green tea is<br />
typically consumed.
<strong>In</strong>teractions With Medications I<br />
• Adenosine (used for irregular heart rhythm):<br />
Green tea inhibits action of adenosine.<br />
• Green tea contains Vitamin K and can make<br />
coumadin (warfarin) ineffective or less effective.<br />
<strong>The</strong> use of green and aspirin together may<br />
increase your risk of bleeding.<br />
• Beta-lactam Antibiotics (examples include<br />
cephalosporins and penicillins):<br />
Green tea may increase the effectiveness of<br />
beta-lactam antibiotics by reducing bacterial<br />
resistance to treatment.<br />
• Benzodiazepines (used for anxiety;) , Green tea<br />
reduces the sedative effects of benzodiazepines.
<strong>In</strong>teractions With Medications II<br />
• Beta-blockers :Green tea can increase blood<br />
pressure in people taking beta blockers.<br />
• Clozapine Green tea can reduce the<br />
effectiveness of clozapine if green tea is taken<br />
less than 40 minutes before taking clozapine.<br />
• Ephedrine Green tea and ephedrine together<br />
will increase the incidence of agitation, tremors,<br />
insomnia, and weight loss.
<strong>In</strong>teractions With Medications III<br />
• Lithium (for treatment of mania and<br />
depression):<br />
Green tea can reduce blood levels of lithium (a<br />
medication used to treat manic/depression).<br />
• Monoamine oxidase inhibitors (MAOIs) (used<br />
for treating depression; examples include<br />
phenelzine and tranylcypromine):<br />
Green tea and MAOI's taken together may cause<br />
hypertensive crisis (severe increase in blood<br />
pressure).

L-Carnitine I<br />
• Between two and four grams of L-carnitine should be<br />
taken one hour before exercise, for two weeks .<br />
• Some studies show positive results and others show no<br />
significant improvements. However, no adverse effects<br />
have been reported from L-carnitine use. This indicates<br />
that carnitine supplementation will produce either<br />
beneficial results or none at all .<br />
• Taking the right amount of carnitine is important to<br />
derive the benefits reported in scientific studies. For<br />
nutritional purposes or as part of a cardiovascularwellness<br />
program, 500 to 1,500 mg per day of L-<br />
carnitine should maintain tissue levels of carnitine.<br />
Lower levels of 100 to 500 mg may also be useful if<br />
taken on a regular basis.
