What body part enters the water first during the backstroke arm pull?

In the backstroke, the sequence of movements during the arm pull is crucial for maximizing efficiency and speed in the water. The hand is the first body part to enter the water at the beginning of the arm pull. This allows for a streamlined entry, reducing drag and setting up an effective catch phase where the swimmer can begin to pull water effectively.

When the hand enters the water first, it creates a natural alignment that facilitates the proper positioning of the arm and shoulder as the swimmer extends and then begins the pull phase. Entering the water with the hand allows the athlete to maintain a relaxed and efficient stroke, setting the foundation for a strong pull with the rest of the arm and body to follow.

Other body parts like the elbow, shoulder, and wrist follow after the hand, primarily because they are positioned in a way that allows the hand to lead into the water. This technique is essential for effective backstroke swimming and contributes to the overall fluidity of the stroke.
