EL PASO – The two boys wrestling on a padded mat inside a chain-link cage barely tall enough to ride the teacups at Disneyland grab at each other, one grasping the other’s leg leaving himself vulnerable as his opponent throws him off-balance.

This is the sport of children’s mixed martial arts or MMA, a new trend in this fast growing sport with children less than 10 years of age strapping on gloves and shin guards in order to pummel one another.
