The high jump technique known as the 'FLOP' involves the athlete taking off from one foot and then using their arms to propel themselves over the bar. The athlete then lands on their back, with their feet in the air, and their arms and legs spread out. This technique is used by many high jumpers because it allows them to generate more power and momentum than other techniques. It is also considered to be a safer technique than other methods, as it reduces the risk of injury.
