What is one of the tasks performed during the catch phase of the back crawl?

Kick the legs hard
Extend the arm forward to grab the water
Pull the arm down swiftly
Rotate the hips

The correct answer is: Extend the arm forward to grab the water

In the catch phase of the back crawl, extending the arm forward to grab the water is crucial because it sets up the swimmer for an effective stroke. This phase involves reaching forward with one arm while the other arm is recovering. By fully extending the arm into the water, the swimmer maximizes the surface area that will engage with the water when the pull phase begins. This action helps initiate the pull effectively, allowing for better propulsion through the water. Additionally, a proper catch aids in maintaining body alignment and overall efficiency in the stroke. The other options, while they pertain to aspects of swimming, do not accurately describe the primary action taken during the catch phase. Kicking the legs hard is important for propulsion, but it occurs concurrently with the arm movements rather than being part of the catch itself. Pulling the arm down swiftly relates more to the pull phase, where the action of drawing the arm through the water occurs. Moreover, rotating the hips is important for overall body movement in swimming, but it is not specific to the catch phase where the focus is on reaching and initiating the pull with the arm.
