Demonstrations are planned in Bolivia and Ecuador over a ban by football body Fifa on internationals more than 2,500m (8,200ft) above sea level.
Fifa says there are fears that the high altitude can harm players' health and possibly distort competition.
Bolivian President Evo Morales has called a meeting of officials from Latin American countries that play their home games at altitude.
He vowed Latin America would not be divided by the "shady actions" of Fifa.
Demonstrators in the Bolivian capital, La Paz, plan a protest of physical exercise to prove there is no ill effect.
President Morales will take part in a football match at Bolivia's largest stadium, the Hernando Siles.
I agree with the protesters. The beauty of the game is that you can play it anywhere. When FIFA starts legislating venue, they're taking something important from the game.
FIFA has also more or less banned football in Lesotho, a country entirely high-altitude.
