As a result, AAS users may get misdiagnosed by a psychiatrist not told about their habit. Use of performance-enhancing drugs in sport. Mini Rev Med Chem. To assist the cook there were also assorted knives, stirring spoons, ladles and graters. It would typically consist of dragées and mulled wine accompanied by aged cheese , and by the Late Middle Ages could also include fresh fruit covered in sugar, honey or syrup and boiled-down fruit pastes. Principles of Pharmacology for Athletic Trainers 2nd ed. Although a lower percentage of these calories will come from fat sources, the total number of fat calories burned will likely be the same or greater.
Kippers made from herring caught in the North Sea could be found in markets as far away as Constantinople. Stockfish , cod that was split down the middle, fixed to a pole and dried, was very common, though preparation could be time-consuming, and meant beating the dried fish with a mallet before soaking it in water. A wide range of mollusks including oysters , mussels and scallops were eaten by coastal and river-dwelling populations, and freshwater crayfish were seen as a desirable alternative to meat during fish days.
Compared to meat, fish was much more expensive for inland populations, especially in Central Europe, and therefore not an option for most. Freshwater fish such as pike , carp , bream , perch , lamprey and trout were common. While in modern times, water is often drunk with a meal, in the Middle Ages, however, concerns over purity, medical recommendations and its low prestige value made it less favored, and alcoholic beverages were preferred.
They were seen as more nutritious and beneficial to digestion than water, with the invaluable bonus of being less prone to putrefaction due to the alcohol content. Wine was consumed on a daily basis in most of France and all over the Western Mediterranean wherever grapes were cultivated.
Further north it remained the preferred drink of the bourgeoisie and the nobility who could afford it, and far less common among peasants and workers. The drink of commoners in the northern parts of the continent was primarily beer or ale. Juices , as well as wines, of a multitude of fruits and berries had been known at least since Roman antiquity and were still consumed in the Middle Ages: Medieval drinks that have survived to this day include prunellé from wild plums modern-day slivovitz , mulberry gin and blackberry wine.
Many variants of mead have been found in medieval recipes, with or without alcoholic content. However, the honey -based drink became less common as a table beverage towards the end of the period and was eventually relegated to medicinal use. This is partially true since mead bore great symbolic value at important occasions.
When agreeing on treaties and other important affairs of state, mead was often presented as a ceremonial gift. It was also common at weddings and baptismal parties, though in limited quantity due to its high price. In medieval Poland , mead had a status equivalent to that of imported luxuries, such as spices and wines. Plain milk was not consumed by adults except the poor or sick, being reserved for the very young or elderly, and then usually as buttermilk or whey.
Fresh milk was overall less common than other dairy products because of the lack of technology to keep it from spoiling. However, neither of these non-alcoholic social drinks were consumed in Europe before the late 16th and early 17th century. Wine was commonly drunk and was also regarded as the most prestigious and healthy choice. According to Galen 's dietetics it was considered hot and dry but these qualities were moderated when wine was watered down.
Unlike water or beer, which were considered cold and moist, consumption of wine in moderation especially red wine was, among other things, believed to aid digestion, generate good blood and brighten the mood.
The first pressing was made into the finest and most expensive wines which were reserved for the upper classes. The second and third pressings were subsequently of lower quality and alcohol content. Common folk usually had to settle for a cheap white or rosé from a second or even third pressing, meaning that it could be consumed in quite generous amounts without leading to heavy intoxication.
For the poorest or the most pious , watered-down vinegar similar to Ancient Roman posca would often be the only available choice.
The aging of high quality red wine required specialized knowledge as well as expensive storage and equipment, and resulted in an even more expensive end product.
Judging from the advice given in many medieval documents on how to salvage wine that bore signs of going bad, preservation must have been a widespread problem. Even if vinegar was a common ingredient, there was only so much of it that could be used. In the 14th century cookbook Le Viandier there are several methods for salvaging spoiling wine; making sure that the wine barrels are always topped up or adding a mixture of dried and boiled white grape seeds with the ash of dried and burnt lees of white wine were both effective bactericides , even if the chemical processes were not understood at the time.
Wine was believed to act as a kind of vaporizer and conduit of other foodstuffs to every part of the body, and the addition of fragrant and exotic spices would make it even more wholesome. Spiced wines were usually made by mixing an ordinary red wine with an assortment of spices such as ginger , cardamom , pepper , grains of paradise , nutmeg , cloves and sugar. These would be contained in small bags which were either steeped in wine or had liquid poured over them to produce hypocras and claré.
By the 14th century, bagged spice mixes could be bought ready-made from spice merchants. While wine was the most common table beverage in much of Europe, this was not the case in the northern regions where grapes were not cultivated. Those who could afford it drank imported wine, but even for nobility in these areas it was common to drink beer or ale , particularly towards the end of the Middle Ages.
In England , the Low Countries , northern Germany , Poland and Scandinavia , beer was consumed on a daily basis by people of all social classes and age groups. For most medieval Europeans, it was a humble brew compared with common southern drinks and cooking ingredients, such as wine, lemons and olive oil. Even comparatively exotic products like camel 's milk and gazelle meat generally received more positive attention in medical texts.
Beer was just an acceptable alternative and was assigned various negative qualities. In , the Sienese physician Aldobrandino described beer in the following way:. But from whichever it is made, whether from oats, barley or wheat, it harms the head and the stomach, it causes bad breath and ruins the teeth , it fills the stomach with bad fumes, and as a result anyone who drinks it along with wine becomes drunk quickly; but it does have the property of facilitating urination and makes one's flesh white and smooth.
The intoxicating effect of beer was believed to last longer than that of wine, but it was also admitted that it did not create the "false thirst" associated with wine. Though less prominent than in the north, beer was consumed in northern France and the Italian mainland.
Perhaps as a consequence of the Norman conquest and the travelling of nobles between France and England, one French variant described in the 14th century cookbook Le Menagier de Paris was called godale most likely a direct borrowing from the English "good ale" and was made from barley and spelt , but without hops. In England there were also the variants poset ale , made from hot milk and cold ale, and brakot or braggot , a spiced ale prepared much like hypocras.
That hops could be used for flavoring beer had been known at least since Carolingian times, but was adopted gradually due to difficulties in establishing the appropriate proportions.
Before the widespread use of hops, gruit , a mix of various herbs , had been used. Gruit had the same preserving properties as hops, though less reliable depending on what herbs were in it, and the end result was much more variable. Another flavoring method was to increase the alcohol content, but this was more expensive and lent the beer the undesired characteristic of being a quick and heavy intoxicant.
Hops may have been widely used in England in the tenth century; they were grown in Austria by and in Finland by , and possibly much earlier. Before hops became popular as an ingredient, it was difficult to preserve this beverage for any time, and so, it was mostly consumed fresh.
Quantities of beer consumed by medieval residents of Europe, as recorded in contemporary literature, far exceed intakes in the modern world. For example, sailors in 16th century England and Denmark received a ration of 1 imperial gallon 4.
Polish peasants consumed up to 3 litres 0. In the Early Middle Ages beer was primarily brewed in monasteries , and on a smaller scale in individual households. By the High Middle Ages breweries in the fledgling medieval towns of northern Germany began to take over production.
Though most of the breweries were small family businesses that employed at most eight to ten people, regular production allowed for investment in better equipment and increased experimentation with new recipes and brewing techniques. These operations later spread to the Netherlands in the 14th century, then to Flanders and Brabant , and reached England by the 15th century. Hopped beer became very popular in the last decades of the Late Middle Ages. When perfected as an ingredient, hops could make beer keep for six months or more, and facilitated extensive exports.
In turn, ale or beer was classified into "strong" and "small", the latter less intoxicating, regarded as a drink of temperate people, and suitable for consumption by children.
As late as , John Locke stated that the only drink he considered suitable for children of all ages was small beer, while criticizing the apparently common practice among Englishmen of the time to give their children wine and strong alcohol.
By modern standards, the brewing process was relatively inefficient, but capable of producing quite strong alcohol when that was desired. One recent attempt to recreate medieval English "strong ale" using recipes and techniques of the era albeit with the use of modern yeast strains yielded a strongly alcoholic brew with original gravity of 1.
The ancient Greeks and Romans knew of the technique of distillation , but it was not practiced on a major scale in Europe until some time around the 12th century, when Arabic innovations in the field combined with water-cooled glass alembics were introduced. Distillation was believed by medieval scholars to produce the essence of the liquid being purified, and the term aqua vitae "water of life" was used as a generic term for all kinds of distillates.
Alcoholic distillates were also occasionally used to create dazzling, fire-breathing entremets a type of entertainment dish after a course by soaking a piece of cotton in spirits. It would then be placed in the mouth of the stuffed, cooked and occasionally redressed animals, and lit just before presenting the creation.
Aqua vitae in its alcoholic forms was highly praised by medieval physicians. In Arnaldus of Villanova wrote that "[i]t prolongs good health, dissipates superfluous humours, reanimates the heart and maintains youth. By the 13th century, Hausbrand literally "home-burnt" from gebrannter wein, brandwein ; "burnt [distilled] wine" was commonplace, marking the origin of brandy.
Towards the end of the Late Middle Ages, the consumption of spirits became so ingrained even among the general population that restrictions on sales and production began to appear in the late 15th century. In the city of Nuremberg issued restrictions on the selling of aquavit on Sundays and official holidays. Spices were among the most luxurious products available in the Middle Ages, the most common being black pepper , cinnamon and the cheaper alternative cassia , cumin , nutmeg , ginger and cloves.
They all had to be imported from plantations in Asia and Africa , which made them extremely expensive, and gave them social cachet such that pepper for example was hoarded, traded and conspicuously donated in the manner of gold bullion.
The value of these goods was the equivalent of a yearly supply of grain for 1. Sugar , unlike today, was considered to be a type of spice due to its high cost and humoral qualities. Even when a dish was dominated by a single flavor it was usually combined with another to produce a compound taste, for example parsley and cloves or pepper and ginger. Common herbs such as sage , mustard , and parsley were grown and used in cooking all over Europe, as were caraway , mint , dill and fennel.
Many of these plants grew throughout all of Europe or were cultivated in gardens, and were a cheaper alternative to exotic spices. Mustard was particularly popular with meat products and was described by Hildegard of Bingen — as poor man's food. While locally grown herbs were less prestigious than spices, they were still used in upper-class food, but were then usually less prominent or included merely as coloring.
Anise was used to flavor fish and chicken dishes, and its seeds were served as sugar-coated comfits. Surviving medieval recipes frequently call for flavoring with a number of sour, tart liquids.
Wine, verjuice the juice of unripe grapes or fruits vinegar and the juices of various fruits, especially those with tart flavors, were almost universal and a hallmark of late medieval cooking.
In combination with sweeteners and spices, it produced a distinctive "pungeant, fruity" flavor. Equally common, and used to complement the tanginess of these ingredients, were sweet almonds.
They were used in a variety of ways: This last type of non-dairy milk product is probably the single most common ingredient in late medieval cooking and blended the aroma of spices and sour liquids with a mild taste and creamy texture. Salt was ubiquitous and indispensable in medieval cooking. Salting and drying was the most common form of food preservation and meant that fish and meat in particular were often heavily salted.
Many medieval recipes specifically warn against oversalting and there were recommendations for soaking certain products in water to get rid of excess salt. The richer the host, and the more prestigious the guest, the more elaborate would be the container in which it was served and the higher the quality and price of the salt. Wealthy guests were seated " above the salt ", while others sat "below the salt", where salt cellars were made of pewter, precious metals or other fine materials, often intricately decorated.
The rank of a diner also decided how finely ground and white the salt was. Salt for cooking, preservation or for use by common people was coarser; sea salt, or "bay salt", in particular, had more impurities, and was described in colors ranging from black to green. Expensive salt, on the other hand, looked like the standard commercial salt common today.
The term " dessert " comes from the Old French desservir , "to clear a table", literally "to un-serve", and originated during the Middle Ages. It would typically consist of dragées and mulled wine accompanied by aged cheese , and by the Late Middle Ages could also include fresh fruit covered in sugar, honey or syrup and boiled-down fruit pastes.
Sugar , from its first appearance in Europe, was viewed as much as a drug as a sweetener; its long-lived medieval reputation as an exotic luxury encouraged its appearance in elite contexts accompanying meats and other dishes that to modern taste are more naturally savoury. There was a wide variety of fritters , crêpes with sugar, sweet custards and darioles , almond milk and eggs in a pastry shell that could also include fruit and sometimes even bone marrow or fish. Marzipan in many forms was well known in Italy and southern France by the s and is assumed to be of Arab origin.
The English chefs also had a penchant for using flower petals such as roses , violets , and elder flowers. An early form of quiche can be found in Forme of Cury , a 14th-century recipe collection, as a Torte de Bry with a cheese and egg yolk filling.
The ever-present candied ginger, coriander , aniseed and other spices were referred to as épices de chambre "parlor spices" and were taken as digestibles at the end of a meal to "close" the stomach. Just like Montpellier , Sicily was once famous for its comfits , nougat candy torrone , or turrón in Spanish and almond clusters confetti. From the south, the Arabs also brought the art of ice cream making that produced sorbet and several examples of sweet cakes and pastries; cassata alla Siciliana from Arabic qas'ah , the term for the terra cotta bowl with which it was shaped , made from marzipan, sponge cake and sweetened ricotta and cannoli alla Siciliana , originally cappelli di turchi "Turkish hats" , fried, chilled pastry tubes with a sweet cheese filling.
Research into medieval foodways was, until around , a much neglected field of study. Misconceptions and outright errors were common among historians, and are still present in as a part of the popular view of the Middle Ages as a backward, primitive and barbaric era.
Medieval cookery was described as revolting due to the often unfamiliar combination of flavors, the perceived lack of vegetables and a liberal use of spices.
The preservation techniques available at the time, although crude by today's standards, were perfectly adequate. The astronomical cost and high prestige of spices, and thereby the reputation of the host, would have been effectively undone if wasted on cheap and poorly handled foods.
The common method of grinding and mashing ingredients into pastes and the many potages and sauces has been used as an argument that most adults within the medieval nobility lost their teeth at an early age, and hence were forced to eat nothing but porridge, soup and ground-up meat.
The image of nobles gumming their way through multi-course meals of nothing but mush has lived side by side with the contradictory apparition of the "mob of uncouth louts disguised as noble lords who, when not actually hurling huge joints of greasy meat at one another across the banquet hall, are engaged in tearing at them with a perfectly healthy complement of incisors, canines, bicuspids and molars". The numerous descriptions of banquets from the later Middle Ages concentrated on the pageantry of the event rather than the minutiae of the food, which was not the same for most banqueters as those choice mets served at the high table.
Banquet dishes were apart from mainstream of cuisine, and have been described as "the outcome of grand banquets serving political ambition rather than gastronomy ; today as yesterday" by historian Maguelonne Toussant-Samat.
Cookbooks , or more specifically, recipe collections, compiled in the Middle Ages are among the most important historical sources for medieval cuisine. The first cookbooks began to appear towards the end of the 13th century. The Liber de coquina , perhaps originating near Naples , and the Tractatus de modo preparandi have found a modern editor in Marianne Mulon, and a cookbook from Assisi found at Châlons-sur-Marne has been edited by Maguelonne Toussaint-Samat.
Few in a kitchen, at those times, would have been able to read, and working texts have a low survival rate. The recipes were often brief and did not give precise quantities. Cooking times and temperatures were seldom specified since accurate portable clocks were not available and since all cooking was done with fire. At best, cooking times could be specified as the time it took to say a certain number of prayers or how long it took to walk around a certain field.
Professional cooks were taught their trade through apprenticeship and practical training, working their way up in the highly defined kitchen hierarchy. A medieval cook employed in a large household would most likely have been able to plan and produce a meal without the help of recipes or written instruction. Due to the generally good condition of surviving manuscripts it has been proposed by food historian Terence Scully that they were records of household practices intended for the wealthy and literate master of a household, such as the Ménagier de Paris from the late 14th century.
Over 70 collections of medieval recipes survive today, written in several major European languages. The repertory of housekeeping instructions laid down by manuscripts like the Ménagier de Paris also include many details of overseeing correct preparations in the kitchen.
Towards the onset of the early modern period , in , the Vatican librarian Bartolomeo Platina wrote De honesta voluptate et valetudine "On honourable pleasure and health" and the physician Iodocus Willich edited Apicius in Zurich in High-status exotic spices and rarities like ginger , pepper , cloves , sesame , citron leaves and "onions of Escalon"  all appear in an eighth-century list of spices that the Carolingian cook should have at hand.
It was written by Vinidarius , whose excerpts of Apicius  survive in an eighth century uncial manuscript. Vinidarius' own dates may not be much earlier. From Wikipedia, the free encyclopedia.

Diversions of a Naturalist. Long-term steroid abusers may develop symptoms of dependence and withdrawal on discontinuation of AAS". Recreational AAS use appears to be associated with a range of potentially prolonged psychiatric effects, including dependence syndromes, mood disorders , and progression to other forms of substance abuse, but the prevalence and severity of these various effects remains poorly understood.
Large-scale long-term studies of psychiatric effects on AAS users are not currently available. DSM-IV lists General diagnostic criteria for a personality disorder guideline that "The pattern must not be better accounted for as a manifestation of another mental disorder, or to the direct physiological effects of a substance e. As a result, AAS users may get misdiagnosed by a psychiatrist not told about their habit.
Affective disorders have long been recognised as a complication of AAS use. From the mids onward, the media reported "roid rage" as a side effect of AAS. A review determined that some, but not all, randomized controlled studies have found that AAS use correlates with hypomania and increased aggressiveness, but pointed out that attempts to determine whether AAS use triggers violent behavior have failed, primarily because of high rates of non-participation.
Compared with individuals that did not use steroids, young adult males that used AAS reported greater involvement in violent behaviors even after controlling for the effects of key demographic variables, previous violent behavior, and polydrug use. The drug response was highly variable. The mechanism of these variable reactions could not be explained by demographic, psychological, laboratory, or physiological measures.
A study of two pairs of identical twins, in which one twin used AAS and the other did not, found that in both cases the steroid-using twin exhibited high levels of aggressiveness, hostility, anxiety, and paranoid ideation not found in the "control" twin.
The relationship between AAS use and depression is inconclusive. There have been anecdotal reports of depression and suicide in teenage steroid users,  but little systematic evidence. A review found that AAS may both relieve and cause depression, and that cessation or diminished use of AAS may also result in depression, but called for additional studies due to disparate data. Androgens such as testosterone , androstenedione and dihydrotestosterone are required for the development of organs in the male reproductive system , including the seminal vesicles , epididymis , vas deferens , penis and prostate.
The pharmacodynamics of AAS are unlike peptide hormones. However, as fat-soluble hormones, AAS are membrane-permeable and influence the nucleus of cells by direct action.
The pharmacodynamic action of AAS begin when the exogenous hormone penetrates the membrane of the target cell and binds to an androgen receptor AR located in the cytoplasm of that cell. From there, the compound hormone-receptor diffuses into the nucleus, where it either alters the expression of genes  or activates processes that send signals to other parts of the cell.
The effect of AAS on muscle mass is caused in at least two ways: It has been hypothesized that this reduction in muscle breakdown may occur through AAS inhibiting the action of other steroid hormones called glucocorticoids that promote the breakdown of muscles. As their name suggests, AAS have two different, but overlapping, types of effects: Some examples of the anabolic effects of these hormones are increased protein synthesis from amino acids , increased appetite, increased bone remodeling and growth, and stimulation of bone marrow , which increases the production of red blood cells.
Through a number of mechanisms AAS stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles , leading to increased strength.
The androgenic effects of AAS are numerous. Depending on the length of use, the side effects of the steroid can be irreversible. Processes affected include pubertal growth, sebaceous gland oil production, and sexuality especially in fetal development. Some examples of virilizing effects are growth of the clitoris in females and the penis in male children the adult penis size does not change due to steroids [ medical citation needed ] , increased vocal cord size, increased libido , suppression of natural sex hormones , and impaired production of sperm.
Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count. Compounds with a high ratio of androgenic to an anabolic effects are the drug of choice in androgen-replacement therapy e. This disassociation is less marked in humans, where all AAS have significant androgenic effects.
A commonly used protocol for determining the androgenic: The VP weight is an indicator of the androgenic effect, while the LA weight is an indicator of the anabolic effect. Two or more batches of rats are castrated and given no treatment and respectively some AAS of interest. Animal studies also found that fat mass was reduced, but most studies in humans failed to elucidate significant fat mass decrements.
The effects on lean body mass have been shown to be dose-dependent. Both muscle hypertrophy and the formation of new muscle fibers have been observed. The hydration of lean mass remains unaffected by AAS use, although small increments of blood volume cannot be ruled out.
The upper region of the body thorax, neck, shoulders, and upper arm seems to be more susceptible for AAS than other body regions because of predominance of ARs in the upper body. After drug withdrawal, the effects fade away slowly, but may persist for more than 6—12 weeks after cessation of AAS use. Overall, the exercise where the most significant improvements were observed is the bench press. The measurement of the dissociation between anabolic and androgenic effects among AAS is based largely on a simple although arguably unsophisticated and outdated model involving rat tissue bioassays.
The intracellular metabolism theory explains how and why remarkable dissociation between anabolic and androgenic effects can occur despite the fact that these effects are mediated through the same signaling receptor, and of course why dissociation is invariably incomplete.
An animal study found that two different kinds of androgen response elements could differentially respond to testosterone and DHT upon activation of the AR. Changes in endogenous testosterone levels may also contribute to differences in myotrophic—androgenic ratio between testosterone and synthetic AAS. Testosterone can be metabolized by aromatase into estradiol , and many other AAS can be metabolized into their corresponding estrogenic metabolites as well.
The major effect of estrogenicity is gynecomastia woman-like breasts. AAS are androstane or estrane steroids. As well as others such as 1-dehydrogenation e. The most commonly employed human physiological specimen for detecting AAS usage is urine, although both blood and hair have been investigated for this purpose.
The AAS, whether of endogenous or exogenous origin, are subject to extensive hepatic biotransformation by a variety of enzymatic pathways. The primary urinary metabolites may be detectable for up to 30 days after the last use, depending on the specific agent, dose and route of administration.
A number of the drugs have common metabolic pathways, and their excretion profiles may overlap those of the endogenous steroids, making interpretation of testing results a very significant challenge to the analytical chemist.
Methods for detection of the substances or their excretion products in urine specimens usually involve gas chromatography—mass spectrometry or liquid chromatography-mass spectrometry. The use of gonadal steroids pre-dates their identification and isolation.
Medical use of testicle extract began in the late 19th century while its effects on strength were still being studied. In the s, it was already known that the testes contain a more powerful androgen than androstenone , and three groups of scientists, funded by competing pharmaceutical companies in the Netherlands, Germany, and Switzerland, raced to isolate it. The chemical synthesis of testosterone was achieved in August that year, when Butenandt and G.
Wettstein, announced a patent application in a paper "On the Artificial Preparation of the Testicular Hormone Testosterone Androstenoneol. Clinical trials on humans, involving either oral doses of methyltestosterone or injections of testosterone propionate , began as early as Kennedy was administered steroids both before and during his presidency. The development of muscle-building properties of testosterone was pursued in the s, in the Soviet Union and in Eastern Bloc countries such as East Germany, where steroid programs were used to enhance the performance of Olympic and other amateur weight lifters.
In response to the success of Russian weightlifters, the U. The new steroid was approved for use in the U. It was most commonly administered to burn victims and the elderly. The drug's off-label users were mostly bodybuilders and weight lifters. Although Ziegler prescribed only small doses to athletes, he soon discovered that those having abused Dianabol suffered from enlarged prostates and atrophied testes. Three major ideas governed modifications of testosterone into a multitude of AAS: Androgens were discovered in the s and were characterized as having effects described as androgenic i.
Although anabolic steroid was originally intended to specifically describe testosterone-derived steroids with a marked dissociation of anabolic and androgenic effect, it is applied today indiscriminately to all steroids with AR agonism-based anabolic effects regardless of their androgenic potency, including even non-synthetic steroids like testosterone itself.
The legal status of AAS varies from country to country: Unlawful distribution or possession with intent to distribute AAS as a first offense is punished by up to ten years in prison. Those guilty of buying or selling AAS in Canada can be imprisoned for up to 18 months. In Canada, researchers have concluded that steroid use among student athletes is extremely widespread.
A study conducted in by the Canadian Centre for Drug-Free Sport found that nearly 83, Canadians between the ages of 11 and 18 use steroids. AAS are readily available without a prescription in some countries such as Mexico and Thailand. The history of the U.
The same act also introduced more stringent controls with higher criminal penalties for offenses involving the illegal distribution of AAS and human growth hormone.
By the early s, after AAS were scheduled in the U. In the Controlled Substances Act, AAS are defined to be any drug or hormonal substance chemically and pharmacologically related to testosterone other than estrogens , progestins , and corticosteroids that promote muscle growth. The act was amended by the Anabolic Steroid Control Act of , which added prohormones to the list of controlled substances , with effect from January 20, In the United Kingdom, AAS are classified as class C drugs for their illegal abuse potential, which puts them in the same class as benzodiazepines.
Part 1 drugs are subject to full import and export controls with possession being an offence without an appropriate prescription. There is no restriction on the possession when it is part of a medicinal product. Part 2 drugs require a Home Office licence for importation and export unless the substance is in the form of a medicinal product and is for self-administration by a person.
Many other countries have similar legislation prohibiting AAS in sports including Denmark,  France,  the Netherlands  and Sweden. United States federal law enforcement officials have expressed concern about AAS use by police officers. It's not that we set out to target cops, but when we're in the middle of an active investigation into steroids, there have been quite a few cases that have led back to police officers," says Lawrence Payne, a spokesman for the United States Drug Enforcement Administration.
Following the murder-suicide of Chris Benoit in , the Oversight and Government Reform Committee investigated steroid usage in the wrestling industry. The documents stated that 75 wrestlers—roughly 40 percent—had tested positive for drug use since , most commonly for steroids. AAS are frequently produced in pharmaceutical laboratories, but, in nations where stricter laws are present, they are also produced in small home-made underground laboratories, usually from raw substances imported from abroad.
As with most significant smuggling operations, organized crime is involved. In the late s, the worldwide trade in illicit AAS increased significantly, and authorities announced record captures on three continents. In , Finnish authorities announced a record seizure of A year later, the DEA seized In the first three months of , Australian customs reported a record seizures of AAS shipments.
When working at this intensity, a greater percentage of calories burned comes from stored fat. Working anywhere within the cardio zone will improve cardio fitness and burn calories.
The benefit of working in the fat-burning zone is that you target stored fat and thus encourage weight loss. But, keep in mind, that if you work in a higher zone, you burn a greater amount of calories overall—which is important to weight loss. Although a lower percentage of these calories will come from fat sources, the total number of fat calories burned will likely be the same or greater.
Take, for example, a person who burns calories in a minute walk at a heart rate of 55 percent of maximum. Seventy-five percent of those calories, or 75 calories, may come from fat. However, a person who runs those same 15 minutes and burns calories may burn only 50 percent of those calories from fat, but will burn a total of fat calories in the same amount of time.
