Which of the following jumps is NOT categorized as a type involving rotation?

The FX side leap is not categorized as a type involving rotation because it primarily focuses on the lateral movement and elevation of the gymnast rather than rotating their body in the air. In a side leap, the gymnast develops the leap from a standing position and pushes off laterally, emphasizing the extension of the legs to the side without performing any horizontal or vertical rotation of the body.

In contrast, the other options all involve some degree of rotation during the jump. The switch leap incorporates a switch of the legs in a rotational manner, the jump 1/2 includes a half twist which is a clear rotation, and the cat leap 1/1 features a full twist, making these jumps categorized as rotational. Thus, the side leap stands out as it involves no such rotational element, concentrating instead on the leap's height and sideward motion.
