World Amateur Bodybuilding ChampionshipsThe World Amateur Bodybuilding Championships (formerly IFBB Mr. Universe) is a male bodybuilding contest organised by the International Federation of BodyBuilders (IFBB) and first held in 1959. The name was changed in 1976 to avoid confusion with the NABBA Mr. Universe. ClassesFrom 1959-1969 there was just one category of competition - open. In 1970 the competition was split into three height classes: Short (under 5'5"), Medium (under 5'8"), and Tall (5'8") with an overall winner also decided. In 1976 they were abandoned in favour of weight classes. These have changed over the years but as of 2005 they are (weight in brackets is the maximum for this category):
An overall winner award was not awarded between 1976 and 1995. Results
StrategyIn competitive bodybuilding, bodybuilders aspire to develop and maintain an aesthetically pleasing (by bodybuilding standards) body and balanced physique. The competitors show off their bodies by performing a number of poses - bodybuilders spend time practicing their posing as this has a large effect on how they are judged. A bodybuilder's size and shape are far more important than how much he or she can lift. The sport should therefore not be confused with strongman competition or powerlifting, where the main point is on actual physical strength, or with Olympic weightlifting, where the main point is equally split between strength and technique. Though superficially similar to the casual observer, the fields entail a different regimen of training, diet, and basic motivation. Contest preparationThe general strategy adopted by most present-day competitive bodybuilders is to make muscle gains for most of the year (known as the "off-season") and approximately 3-4 months from competition attempt to lose body fat (referred to as "cutting"). In doing this some muscle will be lost but the aim is to keep this to a minimum. There are many approaches used but most involve reducing calorie intake and increasing cardio, while monitoring body fat percentage. In the week leading up to a contest, bodybuilders will begin increasing their water intake so as to upregulate the systems in the body associated with water flushing. They will also increase their sodium intake. At the same time they will decrease their carbohydrate consumption in an attempt to "carb deplete". The goal during this week is to deplete the muscles of glycogen. Two days before the show, sodium intake is reduced by half, and then eliminated completely. The day before the show, water is removed from the diet, and diuretics may be introduced. At the same time carbohydrates are re-introduced into the diet to expand the muscles. This is typically known as "carb-loading." The end result is an ultra-lean bodybuilder with full hard muscles and a dry, vascular appearance. Prior to performing on stage, bodybuilders will apply various products to their skin to improve their muscle definition - these include fake tan commonly called "pro tan" (to make the skin darker) and various oils (to make the skin shiny). They will also use weights to "pump up" by forcing blood to their muscles to improve size and vascularity, and immediately before competition will often eat sugary foods such as chocolate in order to make their veins stand out. In order to achieve muscle growth (hypertrophy), bodybuilders focus in three main lines of action:
Resistance weight trainingResistance weight training causes micro-tears to the muscles being trained; this is generally known as microtrauma. These micro-tears in the muscle contribute to the soreness felt after exercise, called delayed onset muscle soreness (DOMS). It is the repair to these micro-trauma that result in muscle growth. Normally, this soreness becomes most apparent a day or two after a workout.

Generally speaking, bodybuilders require more Calories than the average person of the same height, bodybuilders need a higher amount of calories above their 'maintenance level' in order to increase muscle mass. A sub-maintenance level of food energy is combined with cardiovascular exercise to lose body fat in preparation for a contest. The ratios of food energy from carbohydrates, proteins, and fats vary depending on the goals of the bodybuilder. Carbohydrates play an important role for bodybuilders. Carbohydrates give the body energy to deal with the rigors of training and recovery. Bodybuilders seek out low-glycemic polysaccharides and other slowly-digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat rather than muscle, and which can waste energy that should be directed towards muscle growth. However, bodybuilders frequently do ingest some quickly-digesting sugars (often in form of pure dextrose or maltodextrin) after a workout. This may help to replenish glycogen stores within the muscle, and to stimulate muscle protein synthesis. Protein is probably one of the most important parts of the diet for the bodybuilder to consider. Functional proteins such as motor proteins which include myosin, kinesin, and dynein generate the forces exerted by contracting muscles. Current advice says that bodybuilders should consume 25-30% of protein per total calorie intake to further their goal of maintaining and improving their body composition. This is a widely debated topic, with many arguing that 1 gram of protein per pound of body weight is ideal, some suggesting that less is sufficient, and others recommending 1.5, 2, or more. It is believed that protein needs to be consumed frequently throughout the day, especially during/after a workout, and before sleep. There is also some debate concerning the best type of protein to take. Meat, fish, eggs and dairy foods are high in protein, as are some nuts, seeds, beans and lentils. Casein or whey are often used to supplement the diet with additional protein. Whey protein is the type of protein contained in many popular brands of protein supplements, and is preferred by many bodybuilders because of its high Biological Value (BV) and quick absorption rates. Bodybuilders usually require higher quality protein with a high BV rather than relying on protein such as soy, which is often avoided due to its estrogenic properties. Still, some nutrition experts believe that soy, flax seeds and many other plants that contain the weak estrogen-like compounds or phytoestrogens can be used beneficially as phytoestrogens compete with this hormone for receptor sites in the male body and can block its actions. This can also include some inhibition of pituitary functions while stimulating the P450 system (the system that eliminates chemicals, hormones, drugs and metabolic waste product from the body) in the liver to more actively process and excrete excess estrogen. Bodybuilders usually split their food intake for the day into 5 to 7 meals of roughly equal nutritional content and attempt to eat at regular intervals (normally between 2 and 3 hours). This process used to be considered a mechanism for increasing basal metabolic rate when compared to less frequent meals with the same energy content, but research has debunked this myth.
