Fosbury Flop

Richard Douglas Fosbury, who was born in Portland, Oregon, first started experimenting with a new high jump technique at age 16, while attending Medford High School. His hight of 1.93m trumped his ability to maximize his potential to continue using the previous straddle method or the one existing alternative, the upright scissors method. He therefore was unable to go beyond his personal best of 1.80m. Therefore knowing that in order to make further progress would have to try something else. In 1963, at age 16 Fosbury had begun to put the new back-first technique into practice, this involved sprinting diagonally towards the bear, then curves and leap backwards over the bar. After making the US team for the Olympic Games in Mexico City (1968), thanks to a jump of 2.21m. His previous unseen back-technique allowed him to clear the bar right up to 2.22 m. He then went on to clear 2.24m on his third attempt setting s are Olympic record. In fall of 1968, Fosburyâ€™s innovation style was now embraced as the accepted standard, allowing high jumpers to break the 2.40m barrier. Fosbury name is now practiced by high jumpers around the world as the Fosbury Flop. Before the Fosbury Flop the jumper had to apply enough force to lift their centre of mass a few inches in order to clear the bar. With the Fosbury flop the jumper can apply the same amount of force allowing them to raise their body much higher than before meaning he can raise the bar so high that his centre of mass cant go any higher his arching body can. The Richards Fosbury Flop was a great leap forward and backwards

Biomechanic Analysis

Analysis – Stability

Needed during launch, so the body position and centre of mass are appropriate for achievement of maximum distance

Is needed during flight to keep centre of gravity in the correct position, above the legs

Jumpers will need to keep centre of gravity low

The lower the centre of gravity equals less energy needed to jump successfully over the bar

Is needed during the run-up phase to have the correct setup for the force producing phase

Lower centre of mass means a larger base of support
