Context: Wrestling is a combat sport involving grappling type techniques such as clinch fighting, throws and takedowns, joint locks, pins and other grappling holds. The sport can either be theatrical for entertainment, or genuinely competitive. A wrestling bout is a physical competition, between two (occasionally more) competitors or sparring partners, who attempt to gain and maintain a superior position. There are a wide range of styles with varying rules with both traditional historic and modern styles. Wrestling techniques have been incorporated into other martial arts as well as military hand-to-hand combat systems., Islambek Tsilimovich Albiev ( Russian :    ) ( born December 28 , 1988 in Grozny , Chechen - Ingush Autonomous Soviet Socialist Republic ) is a Russian wrestler of Chechen origin who won a gold medal at the 2008 Summer Olympic Games in Greco - Roman wrestling ., Greco-Roman (US) or Graeco-Roman (UK) wrestling is a style of wrestling that is practiced worldwide. It was contested at the first modern Olympic Games in 1896 and has been included in every edition of the summer Olympics held since 1908. Two wrestlers are scored for their performance in two three-minute periods, which can be terminated early by a pin (or fall). This style of wrestling forbids holds below the waist; this is the major difference from freestyle wrestling, the other form of wrestling at the Olympics. This restriction results in an emphasis on throws because a wrestler cannot use trips to take an opponent to the ground, or avoid throws by hooking or grabbing the opponent's leg., Freestyle wrestling is a style of amateur wrestling that is practiced throughout the world. Along with Greco-Roman, it is one of the two styles of wrestling contested in the Olympic games. American high school and college wrestling is conducted under different rules and is termed scholastic and collegiate wrestling.
Freestyle wrestling, like collegiate wrestling, has its greatest origins in catch-as-catch-can wrestling and, in both styles, the ultimate goal is to throw and pin your opponent to the mat, which results in an immediate win. Freestyle and collegiate wrestling, unlike Greco-Roman, allow the use of the wrestler's or his opponent's legs in offense and defense. Freestyle wrestling brings together traditional wrestling, judo, and sambo techniques., Subject: islambek albiev, Relation: occupation, Options: (A) combat sport (B) grappling (C) judo (D) major
