The various codes of football share some common
elements . Players of American football , rugby and rugby league positions in a
limited area of the field in the beginning of game adoption. They tend to use
throw and run like the main ways to move the ball , and only a kick in certain
limited circumstances . Body approach is an important skill , and games usually
include brief passages of play from 5 to 90 seconds. Association football ,
Australian rules football and Gaelic football kicks tend to use to move the
ball down the field , with more limited use. Body tackles are less central to
the game, and players are free to move around the field ( offside laws are
usually less stringent ) .
