What does the motion of the arms during sculling primarily aim to achieve?

The motion of the arms during sculling primarily aims to create sustained force in water, which is essential for maintaining stability and control while floating or maneuvering. Sculling involves a back-and-forth motion that optimally positions the hands to push against the water, generating lift and propulsion. This technique allows a swimmer to remain balanced and supported on the water's surface, effectively using the arms to support the body's weight.

Focusing on the creation of sustained force is important because it enables the swimmer to make minor adjustments to maintain buoyancy and positioning with minimal effort. While speed can be a factor in certain types of racing, sculling itself is more about stabilization and control in the water rather than velocity. The method does not primarily focus on freezing the body, which would impede movement and flexibility, nor does it emphasize avoiding water resistance, as some level of drag is inevitable in any movement through water. Instead, the goal is to expertly use water dynamics to enhance buoyancy and stability through the arm movements.
