Barbell Pad (cropped)
A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting, powerlifting and strongman, consisting of a long bar, usually with weights attached at each end. Barbells range in length from to above , although bars longer than are used primarily by powerlifters and are not commonplace. The central portion of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon's Axle), and is often engraved with a knurled crosshatch pattern to help lifters maintain a solid grip. Weight plates slide onto the outer portions of the bar to increase or decrease the desired total weight. Collars are used to prevent plates from moving outward unevenly so that the lifter does not experience uneven force. The barbell is the longer version of the dumbbell that is used for free weight training and competitive sports, such as powerlifting, Olympic weight lifting, and CrossFit. Many exercises can be done using th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Man Lifting A Heavy Barbell
A man is an adult male human. Before adulthood, a male child or adolescent is referred to as a boy. Like most other male mammals, a man's genome usually inherits an X chromosome, X chromosome from the mother and a Y chromosome, Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics that result in even more differences between the sexes. These include greater muscle mass, greater height, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the testicles, sperm ducts, prostate gland and epididymides, and human penis, penis. Secondary sex characteristics include a narrower pelvis and hips, and smaller breasts and Nipple, nipples. Throughout human history, traditional gender roles hav ...

Bushing (bearing)
Plain bearing on a 1906 S-Motor locomotive showing the axle, bearing, oil supply and oiling pad A sliding table with four cylindrical bearings A wheelset from a Great Western Railway (GWR) wagon showing a plain, or journal, bearing end A plain bearing, or more commonly sliding contact bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction bearing), is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore, the part of the shaft in contact with the bearing slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on or the ways on the bed of a lathe. Plain bearings, in general, are the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity. Design The ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Weightlifting At The 1976 Summer Olympics
The weightlifting competition at the 1976 Summer Olympics in Montreal consisted of nine weight classes, all for men only. The clean and press was dropped from the included lifts after the 1972 games in Munich, due to disagreement over proper form. The Games of 1976 were the first Olympics to start testing for anabolic steroids, although athletes were tested only during the competition, thus leaving them free to use performance-enhancing drugs in the years prior. Medal summary Zbigniew Kaczmarek of Poland originally won the 67.5 kg event, Valentin Khristov of Bulgaria originally won the 110 kg event, and Blagoy Blagoev of Bulgaria originally won silver in the 82.5 kg event, but they were disqualified and stripped of their medals after they tested positive for anabolic steroids.

International Weightlifting Federation
The International Weightlifting Federation, aka IWF, is the international governing body for the sport of Weightlifting. Headquartered in Lausanne, Switzerland, it has 193 affiliated national federations. Mohammed Hasan Jalood has been its president since June 2022. The IWF organizes the World Weightlifting Championships, as well as world championship events for Youth and Juniors. It also cooperates with the International Olympic Committee in the organization of Weightlifting events at the Olympic Games; however, weightlifting's inclusion in the 2028 Olympics is uncertain, due to doping issues within the sport, and governance issues within IWF, and weightlifting's inclusion is expected to be decided by an IOC meeting in 2023. Weightlifting is scheduled as a sport in the upcoming 2024 Olympics but with reduced numbers of athletes and events. IWF traces its history to the formation of the "Amateur-Athleten-Weltunion" (Amateur Athletes World Union) in 1905. History The IWF's p ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympic Lifting
Weightlifting (often known as Olympic weightlifting) is a competitive strength sport in which athletes compete in lifting a barbell loaded with weight plates from the ground to overhead, with the aim of successfully lifting the heaviest weights. Athletes compete in two specific ways of lifting the barbell overhead. The '' snatch'' is a wide-grip lift, in which the weighted barbell is lifted overhead in one motion. The ''clean and jerk'' is a combination lift, in which the weight is first taken from the ground to the front of the shoulders (the ''clean''), and then from the shoulders to over the head (the ''jerk''). The sport formerly included a third lift/event known as clean and press. Each weightlifter gets three attempts at both the snatch and the clean and jerk, with the snatch attempted first. An athlete's score is the combined total of the highest successfully-lifted weight in kilograms for each lift. Athletes compete in various weight classes, which are different for each ...
