How has javelin changed over the years?
The redesigned javelin, introduced from 1986 saw the centre of mass moved 40mm forward from its previous position at the centre of pressure. The tip of the javelin was also resigned to be a blunter and less aerodynamic shape. These changes mean that during flight the javelin has an increased downward pitching moment.
What was the original purpose of the javelin?
The javelin has a strong historic record, going back around 3000 years, to the times of the Mycenaean’s and the Romans. The Javelin was originally designed as an offensive weapon and used in favour of the spear as it was lighter and could be thrown rather than thrust, allowing long distance attacks against an enemy.

What’s the difference between ancient and modern javelins?
The one major difference between the javelin of the ancient games and the javelin of more modern times is a leather thong, called an ankyle that was wound around the middle of the shaft. Athletes would hold the javelin by the thong and when the javelin released this thong unwound giving the javelin a spiraled flight.
