The bi-annual championships are for 15 to 19-year-olds, but Scottish development officer Scott Couper has been working with much younger players to try to ensure continuity.
"Having a professional team in Scotland - the Scottish Claymores - is obviously a help," he points out, "but we are now looking at youngsters from the age of seven or eight.
"I have been spending a lot of time in the schools and the enthusiasm for the game is encouraging. I keep telling them that I was 15 before I touched an American football, so they have seven or eight years of a start on me."
The championships begin at Broadwood Stadium, Cumbernauld, on July 28 and games will also be played at Motherwell's Dalzell Park. Entry is free to schoolchildren.
