With the gradual evolution of mankind, the skill is transformed into a sports category and today, it is played by almost all nations over the globe. with wind up and acceleration phases taking approximately 75% of time (1.5 seconds) The javelin was also part of some (though not all) of the many early forms of women's pentathlon, and has always been included in the heptathlon after it replaced the pentathlon in 1981.[9].

The greater the distance the player can throw the javelin, the better his score will be when it comes to competition.

Firstly, we can talk about three successive acceleration phases: Acceleration of the whole thrower-javelin system using the speed and strength of the legs; Acceleration of the thrower’s trunk.

The resulting designs, which made flat landings much less common and reduced the distances thrown, became official for men starting in April 1986 and for women in April 1999, and the world records (then 104.80 m by Uwe Hohn, and 80.00 m by Petra Felke) were reset.
