Which swimming benchmark requires students to swim backstroke with rolling body motion?

The benchmark that requires students to swim backstroke with rolling body motion is associated with the Green Stroke. This level emphasizes the importance of body rotation in the backstroke, which allows swimmers to engage their core muscles and achieve a more efficient and streamlined position in the water. Rolling the body properly can improve stroke effectiveness, increase power, and enhance overall swimming performance.

In the context of swimming instruction, mastering the rolling motion during backstroke is crucial for developing good technique. It helps students understand how to balance their body and maintain momentum, which are essential skills for progressing to more advanced swimming techniques. The Green Stroke level typically represents an intermediate stage, where students consolidate their foundational skills and learn more about refining their strokes, including the integration of body movement.
