Final answer:
The term 'to do the butterfly' refers to a swimming stroke known for requiring coordinated breathing with rhythmic arm and leg movements. Mastering this stroke involves simulating the movement on land with exercises such as catching a ball and making full-palm contact with water.
Step-by-step explanation:
To do the butterfly refers to A) A swimming stroke. This is a style of swimming that demands synchronized breathing techniques as the swimmer performs the stroke. Breathing in swimming, also known as ventilation, is crucial because it involves moving air into and out of the lungs for gas exchange, which is essential for respiration. Understanding the coordination of this process is key for mastering the butterfly stroke.
The butterfly stroke involves a complex movement where both arms move simultaneously in a circular pattern, combined with a dolphin-like kick. Managing the timing of breathing within these movements is challenging but necessary for the efficiency and effectiveness of the stroke.
Exercises like catching a ball while pulling your hands toward your body can help in practicing the coordination required for the butterfly stroke. Similarly, the full palm hitting water in a tub mimics the impact of a swimmer doing a belly flop, which can help train the strength needed for the butterfly stroke's arm movements.
