The early 1970s in athletics is an extremely interesting time. The technique of most sports is not yet settled, and athletes are constantly inventing new methods. What is the best technique for pole vaulting or high jumping?; How to throw a javelin or discus more effectively; The answers to these questions were sought during the games. The most famous of the innovators is Dick Fosbury, the 1968 Olympic champion in the high jump. He was the one who invented the Fosbury flop jump – the style of going over the forearm with the back forward, which is now applied by all athletes. Before the Fosbury flop, the jump was done with the feet forward. Another innovator was Tuariki Delamere, a New Zealander from the University of Washington. Delamere invented a new way of long jumping and called it the “somersault” (Tuba). He first used this technique at the 1974 Commonwealth Games in Christchurch, New Zealand. Although he jumped a distance of 8,40 meters, it was his hands that betrayed him as he rested them on the sand. So the jump was counted at 7,70 meters. Somersaulting is more mechanically efficient, as the angle of repulsion during such a jump becomes greater. Unfortunately, in the same year, the international federation banned any rotation during the long jump, as dangerous for the health of athletes. This restriction is still in place today (Article 30.1.3 of the World Athletics competition rules).
