While not a particularly popular participant sport, diving is one of the more popular Olympic sports with spectators. Successful competitors possess many of the same characteristics as gymnasts and dancers, including strength, flexibility, kinaesthetic judgment and air awareness.

Competitive diving

Most diving competitions consist of three disciplines: 1m and 3m springboards, and the platform. Competitive athletes are divided by gender, and often by age groups as well. In platform events, competitors are allowed to perform their dives on either the five, seven and a half (generally just called seven) or ten meter towers. In major diving meets, including the Olympic Games and the World Championships, platform diving is from the 10 meter height.

Divers must perform a set number of dives according to various established requirements, including somersaults and twists in various directions and from different starting positions. Divers are judged on whether and how well they completed all aspects of the dive, the conformance of their body to the requirements of the nominated dive, and the amount of splash created by their entry to the water. Theoretically, a score out of ten is supposed to be broken down into three points for the takeoff, three for the flight, and three for the entry, with one more available to give the judges flexibility.

The raw score is multiplied by a difficulty factor, derived from the number and combination of movements attempted. The diver with the highest total score after a sequence of dives is declared the winner.

Synchronized diving

Synchronized diving was adopted as an Olympic sport in 2000. In this event, two divers form a team and attempt to perform dives simultaneously. The dives are usually identical; however, sometimes the dives may be opposites, in what is called a pinwheel. In these events, synchronicity is valued as highly as technical skill.

Scoring the dive

Ultimately, the judges' scores given on each dive are subjective. However, there are specific rules governing how a dive is supposed to be scored. Usually a score factors three elements of the dive: the approach, the flight, and the entry. The primary factors affecting the scoring are: (1) the platform selected (10-meter, 7.5-meter, or 5-meter), (2) if a hand-stand is required, the length of time and quality of the hold, (3) the height of the diver at the apex of the dive, with extra height resulting in a higher score, (4) the distance of the diver from the diving apparatus throughout the dive (a diver must not be dangerously close, should not be too far away, but should ideally be within of the platform), (5) the properly defined body position of the diver according to the dive being performed, including pointed toes and feet touching at all times, (6) the proper amounts of rotation and revolution upon completion of the dive and entry into the water, and (7) angle of entry (a diver should enter the water straight, without any angle). Many judges award divers for the amount of splash created by the diver on entry, with less splash resulting in a higher score.
