The 100-meter butterfly is a competitive swimming event where athletes swim two lengths of a standard Olympic pool using the butterfly stroke. This stroke involves a simultaneous arm movement and a unique dolphin kick, requiring strength and coordination. Swimmers start from the water's edge and dive in, aiming to complete the distance as quickly as possible. In this event, swimmers must execute specific techniques, including a powerful start, efficient turns, and a strong finish. The butterfly stroke is known for its difficulty, making the 100-meter butterfly a test of both speed and endurance in the sport of swimming.
