Measurements were conducted in imperial distances (feet and inches) until 1975. Metrication occurred in 1976, so all subsequent championships were measured in metric distances. In 1986, international javelin design regulations were changed and the center of gravity of the implement moved forward.
Additionally, high-school competition is conducted under slightly different rules, which have evolved over time. For example, in 1980, high schools converted their running distances from Imperial (yards) to metric, but instead of running conventional international distances like 1500 metres in place of the mile run, a more equitable but non ...

A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon. Today, the javelin is predominantly used for sporting purposes such as the javelin throw . The javelin is nearly always thrown by hand, unlike the sling , bow , and crossbow , which launch projectiles with the aid of a hand-held mechanism.

Absolute geometry is a geometry based on an axiom system consisting of all the axioms giving Euclidean geometry except for the parallel postulate or any of its alternatives. [69] The term was introduced by János Bolyai in 1832. [70] It is sometimes referred to as neutral geometry, [71] as it is neutral with respect to the parallel postulate.
Murro was the top American at the Olympics, throwing 80.08 m (262 ft 8 + 1 ⁄ 2 in) and placing ninth; [1] [4] Track & Field News ranked him as the world's 10th best javelin thrower that year. [5] The magazine put him on the cover of its April 1969 issue.
