Have you ever wondered how butterfly stroke body movement is performed so smoothly and elegantly? The secret lies in the swimming action of the dolphin.
Although we are not able to leap over the surface of the water like a dolphin, we are able to mimic the way it moves its body from nose to tail.
When we swim butterfly, our body should undulate from head to toe, producing a dolphin-type action. This type of movement gives the stroke smooth and seamless action.
The body movement for butterfly stroke is a continuous undulating action that requires strength and power. When performed correctly, the movement provides the propulsion and drive needed to keep the overall stroke smooth and efficient.
1. The body position should be kept as horizontal as possible to keep frontal resistance to a minimum.
2. The body should be face down (prone) with the crown of the head leading the action.
3. The shoulders should remain level throughout and the head should remain central and still, looking down until breathing is required.
4. Hips should remain parallel to the direction of travel and be inline with the shoulders.
5. Intermittent or alternating breathing will help to maintain a smooth and steady movement.
Although the movement initiates at the head, it begins as a relatively small movement when practised alone without the arm action. As the undulation progresses through the abdominal area and to the hips, the movement becomes larger and more pronounced.
The up and down movement of the hips are very much the driving force behind the undulating motion, finishing with a large bend of the knees and the powerful downward kick of the legs.
The most common mistake made when performing the movement is making the undulation up and down too excessive.
As the movement originates from the head there is a tendency to over exaggerate this movement, causing the wave movement through the rest of the body to be over pronounced.
The swimmer then puts more effort and energy into moving up and down instead of actually swimming forwards.
A simple push and glide exercise from the poolside followed by a gentle undulating movement across the surface of the water help to eliminate any excessive body movements.
If the swimmer places the effort on using the undulation to move forward then this will provide a solid base from which to build and perfect the swimming stroke.
Take your butterfly stroke to the next level with my book 'How To Swim Butterfly'. It contains specific drills for fine-tuning arm pull, leg kick and breathing techniques whilst maintaining an effective butterfly stroke body movement.
