How is the flutter kick performed?

1. By moving the legs in a circular motion

2. By alternating an upward and downward kicking motion

3. By keeping the legs stiff

4. By paddling the legs independently

The correct answer is: By alternating an upward and downward kicking motion

The flutter kick is characterized by an alternating upward and downward kicking motion of the legs. In this technique, the legs move in a linear up-and-down motion, which helps to propel the swimmer forward. The flutter kick is commonly used in various strokes, such as freestyle and backstroke, and is effective in maintaining a streamlined position in the water. This motion allows for both propulsion and balance while swimming. In contrast, other techniques like moving the legs in a circular motion or paddling the legs independently do not align with the mechanics of the flutter kick. Keeping the legs stiff also does not accurately represent the flexibility and fluidity required for an effective flutter kick, as relaxed feet and ankles typically aid in achieving the best propulsion and efficiency. Therefore, the correct description of the flutter kick involves the alternating motion that enables swimmers to enhance their speed and streamline their body position in the water.
