The United States Soccer Federation has outlined plans to stop children aged 10 and under heading footballs.
The plans resolve a concussion lawsuit filed against the federation by parents but US Soccer said it had planned to introduce a new safety campaign.
They also intend to limit the amount of heading in practice for children between the ages of 11 and 13.
"Although these are recommendations, they are based on the advice of the US Soccer medical committee," it said.
"Therefore US Soccer strongly urges that they be followed."
The lawsuit filed by young players and their parents in August 2014 accused governing bodies, including Fifa and the California Youth Soccer Association, of acting "carelessly and negligently" and failing to protect young players.
US Soccer said the reforms would also include "modifications to substitution rules in relation to concussions" and would be "requirements for players that are part of US Soccer's youth national teams and the development academy."
It added: "Protecting the health and safety of athletes and preventing injuries is critically important to US Soccer."
There has been previous criticism of football's attitude towards concussions but new rules have been brought in for Premier League matches after Tottenham goalkeeper Hugo Lloris continued playing after he lost consciousness.
Following those measures Dr Michael Grey, a leading neuroscientist from the University of Birmingham, said it was dangerous for children to head a football.
