Water Safety Instructor (WSI) Practice Exam

What describes the mid-pull phase of the elementary backstroke?

1. The arms should be above water at all times

2. The upper body should twist significantly

3. The arms glide straight back

4. Focus on a gentle flutter kick

The correct answer is: The arms glide straight back

In the mid-pull phase of the elementary backstroke, the arms engage in a movement that is instrumental in generating propulsion and maintaining body position. This phase is characterized by the arms gliding straight back in a manner that helps in effectively pulling the body through the water. The motion of keeping the elbows higher than the hands allows for an efficient catch and pull, which maximizes the swimmer's propulsion while maintaining a streamlined position. The design of this stroke emphasizes a steady and controlled movement that is not only effective but also manageable for learners, making it an ideal option in instruction. Unlike other strokes that might require complex techniques, the elementary backstroke simplifies the process by focusing on straightforward arm movements. This allows swimmers, especially beginners, to feel confident and secure in their movements. The other aspects of the stroke, such as the position of the arms and the body alignment, don’t align with the mid-pull phase as accurately as the described straight back pull does. For example, having the arms above water at all times would negate the propulsion gained from the pull, while significant twisting of the upper body could disrupt balance and efficiency in the stroke. A flutter kick, while used in other strokes, is not a primary focus in the mid-pull phase
