What is a general requirement for elements during traveling?

The requirement for elements during traveling is that they must continually rotate while moving. This is important in synchro skating because it demonstrates the fluidity and dynamic quality of the performance. Continuously rotating elements enhance the visual impact and show the team's control and coordination while in motion.

The act of traveling combined with rotation signifies a higher level of skill, as it requires precise timing and synchronization among team members. This aspect of the performance is crucial for achieving a successful and harmonious execution of elements, which is a key evaluation criterion in synchro skating.

The other options do not align with the fundamental expectations for elements during traveling. For example, remaining stationary would contradict the very definition of traveling, and stopping at any point would disrupt the flow necessary for cohesive movement. Hence, maintaining continuous rotation enhances both the aesthetic and technical quality of the synchronized performance.
