description Jackknife (Diving/Gymnastics) Overview
In diving, a jackknife is a position or movement in which the diver bends sharply at the hips while keeping the legs extended, creating an angle between the upper and lower body before entering the water. The position appears in dives that include a pike-like body fold and is judged through body control, alignment, and execution. In gymnastics and other acrobatic contexts, the term can describe a related folding action, but its exact use depends on the discipline's terminology.
help Jackknife (Diving/Gymnastics) FAQ
What is a jackknife position in diving?
A jackknife is a sharp bend at the hips with the legs kept extended. The diver folds the upper body toward the legs before opening the body for entry into the water.
How is a jackknife different from a pike position?
They describe a very similar hip-folded body shape, and diving terminology often uses pike for the position itself. Jackknife commonly refers to the movement or dive action that includes that fold.
Does a jackknife dive require the legs to stay straight?
Yes, the defining shape uses extended legs while the body bends at the hips. Bending the knees changes the position and reduces the clean pike-like line expected in the skill.
Is a jackknife used only in diving?
The term is strongly associated with diving, where it appears in dives with a pike-style fold. Related hip-folding shapes can also appear in gymnastics and acrobatics, but the scoring rules are different.
