Cheerleading is an activity in which the participants (called "cheerleaders") cheer for their team as a form of encouragement. It can range from chanting slogans to intense physical activity. It can be performed to motivate sports teams, to entertain the audience, or for competition. Competitive routines typically range anywhere from one to three minutes, and contain components of tumbling, dance, jumps, cheers, and stunting. (Wikipedia)
