What were old javelin rules?

Old javelin rules, particularly those before the 1980s, allowed athletes to throw javelins with a variety of techniques, including the "straight-arm" method. The javelin used to have a different design, with a lighter weight and a longer tail, which affected the throwing style. Additionally, athletes were required to throw from a specific area, and any throws that landed outside the designated sector were considered invalid. Over time, rules have evolved to standardize equipment and techniques, influencing the sport's competitive nature.
