Which basic skill is essential for successful bowling?

The correct choice emphasizes the importance of coordination and balance in bowling, particularly the concept of "opposite foot, opposite hand." This technique aids in establishing a strong, stable stance and a smooth delivery. When a bowler steps forward with one foot, the opposite hand plays a crucial role in guiding the ball towards the pins.

Using the opposite foot and hand creates a natural motion that promotes balance throughout the bowling process, allowing for better accuracy and power in the throw. This coordinated movement is essential for achieving successful results on the bowling lane, as it enhances body alignment and supports an effective release of the ball.

Each of the other options does not capture the fundamental mechanics necessary for effective bowling. For instance, while using both hands simultaneously may be beneficial in some sports, bowling primarily relies on one hand to deliver the ball correctly. Aligning the shoulders with the pins can be useful for target focus, yet without the foundational skill of opposite foot, opposite hand coordination, it may not translate to effective execution. Lastly, rolling the ball with one hand only is a given in bowling, but it lacks the context of footwork and timing that is encapsulated in the opposite foot, opposite hand principle.
