At the Sydney Olympic in 2000 there were eight diving events for men and women. In these events, individual and synchronized (双人同步的) competitors performed a set number of compulsory and voluntary dives, each of which was given a point score.
Platform
The platform is a non - bending board 10m high - the same height as a three - story building.
Springboard
On the 3m springboard, divers need ability and timing. They use the flex of the board to attain maximum spring.
Judges
Seven judges give each dive a score out of ten. A dive is judged by the approach, take - off, elevation (高度), execution (实施、完成) of movements and entry into water.
Scoring
The highest and lowest scores are got rid of and the remaining five are totaled. The number is mulitiplied by the degree of difficulty rating assigned to each dive. This total is then mulitplied by 0.6 to give the final score.
Competition
When there are more than 16 competitors, a preliminary competition is held. The eight divers with the most points qualify (合格) for the final.
Types of Dives
There are six different groups of dives. Forward, backward, reverse (向后的) and inward dives involve rotating in different directions relative to the board and the starting position. Twisting (旋转) includes any dive with a twist. Armstand dives begin with a handstand position on the edge of the platform.
Body positons
Tuck - The body is bent at the waist and knees, the thighs are drawn to the chest while the heels are close to the buttocks (臀部).
Pike - The legs are straight with the body bent at the waist. The arm position is dictated by the particular dive.
Straight - No bending at the waist or knees is permitted.
Free - The free position is only used in dives that include twists.
Synchronized Diving
Pairs of dives perform a combination of dives at the same time. Nine judges award points with four judges rating the execution of the dives and other five assessing the synchronization (一致，同步) of the two divers.
