What skill is focused on in the Blue Stroke School?

The focus of the Blue Stroke School is on developing the foundational swimming skill of performing the arm action and leg kicking in a coordinated manner. This is essential for swimmers to gain efficiency and propulsion in the water. Mastering these skills helps swimmers establish a strong core component of stroke mechanics, which is necessary as they progress to more advanced techniques. It emphasizes the importance of body balance and the synchronization of arm and leg movements, which are critical for effective swimming. This foundation allows swimmers to transition more successfully into higher levels of swimming where stroke refinement and speed become priorities.

While the other choices represent important skills as part of a comprehensive swim education, they are not the primary focus of the Blue Stroke School level. For instance, retrieving submerged objects and assisting with flotation are skills typically emphasized at different stages in swim instruction, while pulsing with hands may be introduced later in the curriculum as swimmers progress toward more complex strokes. Thus, the correct answer centers on the essential skills that enable swimmers to build a solid technique framework in the water.
