Guide to Diving

Diving is a Dynamic and Thrilling Sport!

Its attraction lies in the combination of the visual appeal of the divers and the challenge to break new boundaries of courage, skill and athleticism.

Diving combines the athleticism of gymnastics, the grace of ballet and the concentration of a chess player.

Diving is a sport that belongs to all - no matter what age, class, sex or skill level - all can participate and progress at their own pace.

Diving is an Olympic Games, Commonwealth Games and University Games Sport.

Types of Dives

There are six different groups of platform and springboard dives.  The first four types involve rotating in different directions relative to the board and the starting position.  The fifth group includes any dive with a twist.  The final group, used in platform diving, begins with an armstand.

  1. Forward Group: The diver faces the front of the board and rotates towards the water.  Dives in this group vary from the simple front dive to the difficult forward four and one-half somersaults.
  2. Backward Group: All the dives in the backward group begin with the diver on the end of the board with the back to the water.  The direction of rotation is away from the board.
  3. Reverse Group: These dives begin with the diver facing the front of the board (using a forward approach) and rotating towards the board.
  4. Inward Group: The diver stands on the end of the board with back to the water and rotates toward the board or opposite of the backward group's movement.
  5. Twisting Group: Any dive with a twist is included in this group.  There are four types of twisting dives: forward, backward, reverse and inward.  Because of the many possible combinations, this group includes more dives than any other.
  6. Armstand Group: In platform diving there is a sixth, unique group of dives called 'armstands'.  Here the diver assumes a handstand position on the edge of the platform before executing the dive. 

Body Positions

When each type of dive is performed, the diver utilises one or more of the four different types of body positions.

  1. Tuck: The body is bent at the waist and knees, the thighs are drawn to the chest while the heels are kept close to the buttocks.
  2. Pike: The legs are straight with the body bent at the waist.  The arm position is dictated by the particular dive being done or by the choice of the diver.
  3. Straight: This position requires that there be no bend at the waist or knees.  However, there may be an arch in the back depending on the dive.  As in the pike position the arm placement is either the diver's choice or defined by the dive done.
  4. Free: This is not an actual body position but a diver's option to use any of the other three positions or combination thereof when performing a dive which includes somersaults and twists.  However, in dives of this kind the tuck position is rarely used, while a combination of the other two positions is the most common occurrence.

Judging

Divers are judged by a panel of seven judges who each give a score between zero and 10 points for each dive performed. The following table gives an indication of the points awarded for dives: 

0                   completely failed
½ – 2            unsatisfactory
2½ - 4½        deficient
5 – 6½           satisfactory
7 – 8              good
8½ – 9½        very good
10                  excellent 

In classifying a dive into one of the judging categories, certain parts of each dive must be analysed and evaluated, and an overall award obtained.  The parts of the dive are:

  • Approach: Should be smooth but forceful, showing good form.
  • Take-off: Must show control and balance, plus the proper angle of landing and leaving for the particular dive being attempted.
  • Elevation: The amount of spring or lift a diver receives from the take-off greatly affects the appearance of the dive. Since more height means more time, a higher dive generally affords greater accuracy and smoothness of movement.
  • Execution: This is most important, for this is the dive. A judge watches for proper mechanical performance, technique, form and grace.
  • Entry: The entry into the water is very significant because it is the last thing the judge sees and the part probably remembered best. The two criteria to be evaluated here are the angle of entry which should be vertical and the amount of splash, which should be as little as possible. 

Synchronised Diving

The synchronised diving competition involves two competitors diving simultaneously from the springboards or platform.  The competition is judged on how they individually perform their dives and how the team synchronises their performance.

Factors to be considered by the synchronised judges include:

  • The approach;
  • The take-off, including the similarity of height;
  • The co-ordinated timing of the movements during the flight;
  • The similarity of the angles of the entries;
  • The comparative distance from the board and platform of entry;
  • The co-ordinated timing of the entries

Scoring

When all seven judges in individual events have allocated a score for a dive, the two highest and two lowest scores will be eliminated and the remaining three scores totalled.  The number will be multiplied by the degree of difficulty (DD) rating assigned to the dive.  The DD is predetermined with a table range from 1.2 to 3.8 in one-tenth increments.  

A scoring example is shown below:
Awards:          6 - 5 - 5 - 5 - 5 - 5 - 4
Total:             15 (high and low scores eliminated - scores in bold counted only)
DD:                2.0
Score:            30 points  

For synchronised diving events either nine or eleven judges are appointed to give a score between zero and ten for each dive. When 9 judges are used, two judges will rate one individual diver, two other judges will rate the second individual diver and five judges will rate the synchronisation of the pair. 

The high and low of the four individual scores will be eliminated, and the high and the low of the five synchronised scores will be eliminated and the remaining five scores totalled.  This is then reduced by 3/5 (0.6) in the tradition that a diver’s score comes from three judges. When 11 judges are used, three judges will rate one individual diver, three judges will rate the second individual diver and five judges will rate the synchronisation of the pair.  

The high and low of each of the three individual scores will be eliminated, and the high and the low of the five synchronised scores will be eliminated, and the remaining five scores totalled.  This is then reduced by 3/5 (0.6) in the tradition that a diver’s score comes from three judges.
