The athlete known for the "Fosbury Flop" technique in high jumping is Dick Fosbury. His innovative approach revolutionized the sport in the late 1960s, allowing him to clear greater heights than traditional styles. Fosbury's unique technique involves jumping backward over the bar, which helped him win a gold medal at the 1968 Mexico City Olympics. His method has since become the standard technique used by high jumpers worldwide, demonstrating how innovation can shape athletic performance and training.
