In terms of technical execution, which jump involves the height achieved by drawing legs towards the body?

The jump that involves the height achieved by drawing the legs towards the body is the FX pike jump. In a pike jump, the gymnast must bend at the waist while keeping their legs straight, drawing their legs upward and bringing their torso closer to them, which requires significant strength and control. This characteristic of drawing the legs toward the body enhances the height achieved during the jump, as it reduces the distance of the legs from the center of gravity.

In contrast, the other options showcase different mechanics and positions. The straight jump maintains a vertical body position with no bending at the waist, which is more about extending the body fully rather than drawing the legs inward. The cat leap involves a slight tuck of the knees but primarily focuses on launching from one foot while transitioning into a leap, whereas the wolf jump features a more distinct bent knee position, emphasizing a tucked appearance rather than the controlled drawing of the legs towards the body found in a pike jump.
