Here is another version of football. Walking football. Rules are same as regular football but players are not allowed run than walk. It was invented in Ukraine but it spread cross world. Players are usually older people who can't run but even younger people play it. it started with the intention of popularizing walking. People move less and less and become obese, so this is a way of exercise that does not require good fitness.
Here is shorts from Youtube but you can find plenty different videos.
