Charles University in Prague (Czech Rep) participated in a biomechanics study on the 1988 Seoul Olympics in athletics. Ben’s start especially was subject of interest with the final observation that he had made a major contribution along the lines of he had managed to raise his centre of mass without raising his centre of gravity, in in some way therefore was able to gain a significant advantage over conventional starters. I may have that wrong because I haven’t seen that video for many years.
