Abstract

The aim of this study was to optimize platform diving techniques of the reverse group using a computer simulation program along with an evolutionary algorithm. We used a planar four-segment model of a diver to study the aerial phase for the reverse 3½ somersault tuck. We fixed the initial angular momentum and five characteristic poses: takeoff, adoption of spinning position, leaving the spinning position, end of come-out, and entry. Starting with real performances of male elite divers executing 306C and 307C performances we found optimal performances for the 307C. The evolutionary algorithm ends up in several different optimal technique variants. The corresponding joint angle patterns are computed and compared. Decreasing knee and hip angles in spinning position by about 20° resulted in a gain of one complete rotation.
