Dives are described by their full name (e.g. reverse 3 1/2 somersault with 1/2 twist) or by their numerical identification (e.g. 5371D), or “dive number.” Twisting dives utilize four numerical digits, while all other dives use three. Specific dive numbers are not random — they are created by using these guidelines:
- All dives are identified by three or four digits and one letter.
- The first digit indicates the dive’s group: 1 = forward, 2 = back, 3 = reverse, 4 = inward, 5 = twisting, 6 = armstand
- In front, back, reverse and inward dives, a 1 as the second digit indicates a flying action. A ‘0’ indicates none. In twisting and armstand dives, the second digit indicates the dive’s group (forward, back, reverse).
- The third digit indicates the number of half somersaults.
- The fourth digit, if applicable, indicates the number of half twists.
- The letter indicates body position: A = straight, B = pike, C = tuck, D = free.
107B = Forward dive with 3 1/2 somersaults in a pike position
305C = Reverse dive with 2 1/2 somersaults in a tuck position
5253B = Back dive with 2 1/2 somersaults and 1 1/2 twists in a pike position
