Long jump
Somersault

In the 1970s, some jumpers used a forward somersault, including Tuariki Delamere who used it at the 1974 NCAA Championships, and who matched the jump of the then Olympic champion Randy Williams. The somersault jump has potential to produce longer jumps than other techniques because in the flip, no power is lost countering forward momentum, and it reduces wind resistance in the air. The front flip jump was subsequently banned for fear that it was unsafe.
