Weightlifting competition process
1. Draw lots: at the technical meeting. The deputy referee will lead the recorder and the recorder to draw lots at one time according to the order book of the conference. The lottery determines the order in which athletes weigh themselves and the order in which they try to lift. When drawing lots, regardless of grades, the number of numbers will be determined according to the number of participating athletes.
2. Weighing: Athletes start weighing 2 hours before the competition. The weighing time is 1 hour, which is regarded as abandonment.
3. Trial lifting sequence: Try lifting the light-weight athletes first. When the weight of the first trial hoisting is equal, the order will be determined according to the sign number, and the smaller sign number will be hoisted first. In the second and third attempts, if the weights of the attempts are equal, they should be carried out in the order of the previous interviews.
4. Aggravation principle: On May 1 day, 2005, FIBA withdrew from the historical stage after implementing the "2.5 kg rule" for more than 90 years, and the "1 kg rule" officially appeared. Beijing Olympic Games is the first time to adopt the "1 kg rule" in Olympic weightlifting competition. The so-called "2.5 kg rule" means that apart from breaking the world record, the weight of barbells can only be a multiple of 2.5 kg; "1 kg rule" requires barbell weighing in multiples of 1 kg.
5. Change the weight of the trial lift: An athlete's request to change the weight of the trial lift must be made within 30 seconds before his own trial lift time. When it is too late to fill in the card, the coach or athlete can verbally request to change the weight. But the weight of each attempt can only be changed twice. The total weight of the first snatch and the first clean and jerk should not be lower than the registration score of 20kg, otherwise the competition qualification will be cancelled.
