Which stroke is the oldest and slowest, with high frontal resistance?

• A. Freestyle
• B. Butterfly
• C. Backstroke
• D. Breaststroke

Answer: (D)

In swimming, speed depends on how much propulsion a stroke provides relative to the water’s resistance. Breaststroke is the oldest stroke, and it tends to be the slowest because the propulsion from the arms and legs per cycle is relatively modest, while the body position during the stroke presents a larger frontal area to the water. The wide frog kick and the timing of the arm pull keep water moving backward, but they also create more drag, especially during the glide and recovery phases. This combination of less efficient propulsion and higher frontal resistance makes it slower than the other strokes, which can achieve greater speed with more streamlined bodies and more continuous propulsion. Freestyle and backstroke achieve higher speeds with longer, more streamlined lines, while butterfly, though powerful, demands more energy and has a different mechanical efficiency.
