Some rules in the process of competition

1. Draw lots: at the technical meeting. The deputy referee will lead the recorder and the recorder to draw lots for the athletes of each team 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 people drawn is determined according to the number of athletes attending the conference.

2. Weighing: Athletes begin to weigh themselves 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. Weighting principle: The weight of barbell increases gradually, and the trial lift weight must be a multiple of 2.5 kg, and the record-breaking trial lift weight must be a multiple of 0.5 kg. At least 2.5 kilograms should be added after each successful attempt. The weight of barbell on the field shall not be less than 27.5 kg.

5. Change the weight of the trial lift: The athlete's request to change the weight of the trial lift must be made before the last roll call. 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.

6. Lifting time: after the recorder calls the roll, the allowable interval is 1 minute. The signal was sent in the last half minute. For example, when lifting continuously, an interval of 2 minutes is allowed.

7. Record-breaking regulation: Any object successfully lifted will be deemed as a new record if its weight exceeds 0.5 kg or multiple of 0.5 kg. Once a new record is set, no one can break it with the same weight. The total score must exceed the original record by 2.5 kg before the new record can be recognized.

8. Ranking evaluation: the highest weight lifted in the snatch or clean and jerk three attempts is a single achievement, and the ranking is determined according to the achievement. The total score ranking is determined by the sum of snatch and clean and jerk. If the results are equal, the lighter one will be ranked first before the game. If the score and weight are equal, the athlete who lifts the weight first ranks first.
