context_page_description: Olympic weightlifting, or Olympic-style weightlifting, often simply referred to as weightlifting, is a sport in which the athlete attempts a maximum-weight single lift of a barbell loaded with weight plates.
  The two competition lifts in order are the snatch and the clean and jerk. The snatch is a wide-grip, one-move lift. The clean and jerk is a close-grip, two-move lift. Each weightlifter receives three attempts in each, and the combined total of the highest two successful lifts determines the overall result within a bodyweight category. Bodyweight categories are different for male and female competitors. A lifter who fails to complete at least one successful snatch and one successful clean and jerk also fails to total, and therefore receives an "incomplete" entry for the competition. The clean and press was once a competition lift, but was discontinued due to difficulties in judging proper form.
  In comparison with other strength sports, which test limit strength, weightlifting tests aspects of human ballistic limits; the lifts are therefore executed faster—and with more mobility and a greater range of motion during their execution—than other strength movements.
context_section_description: Olympic weightlifting uses a steel bar (also known as a barbell) with larger-diameter rotating sleeves on either end, holding rubber-coated weight plates of different weights. This sleeve rotation is important for the Olympic lifts, particularly the snatch and clean movements, because it drastically reduces the rotational inertia of the bar. Without sleeve rotation, the Olympic lifter faces more challenging lifts and a greater risk of injury.
  A men's Olympic barbell weighs 20 kg (44 lbs) with a shaft diameter of 28 mm and a length of 2200 mm, whereas a women's Olympic barbell weighs 15 kg (33 lbs) and has a shaft diameter of 25 mm with a length of 2010 mm. The distance between the sleeves, however, is the same for the men's and the women's bars at 1310 mm. The grip texture of the bar is called the knurling, and is distributed differently between the men's and women's bars: the men's has knurling in the centre but the women's does not. The Olympic barbells used in competition are certified by the IWF.
