Cheerleading and cheerleading are different words. The Modern Chinese Dictionary (revised edition) takes cheerleading as the masculine gender. According to People's Daily ~; According to the word frequency statistics of 2000.12000.11,the word frequency ratio between them is 3 1: 12. 1880, American campus football became popular, and the cheerleaders who cheered for them were organized for this kind of game. Cheerleading on the sidelines as we know it today was founded in the winter of 1898. Johnny Cambel, the first cheerleader in American history, stood in front of the audience and directed them to shout a popular slogan for his alma mater, the University of Minnesota, which is still in use today. Traditionally, in the United States, early cheerleaders were composed of boys from colleges and universities. Cheerleading should not only have leadership and excellent results, but also gain recognition and respect from Tongji. Teammates are like "brotherhood" and belong to an honor club. But after World War I, the cheerleading structure of pure boys was changed, and girls began to join the cheerleading ranks. With the active participation of girls in cheerleading, tweeters (loud voices), paper colored balls and gymnastics movements are added to the cheerleading team, which makes the cheerleading performance more lively. In the next 50 years, colleges and universities all over the United States set up cheerleading training camps to teach the basic skills of cheerleading, and Bill Holland established the first national cheerleading association. Then, the invention of vinyl velvet ball and the display of Brewin's new style of high-step enriched the performance content of cheerleading, which made the cheerleading trend sweep across the United States and gradually be adopted by other countries. Later, the cheerleaders added difficult gymnastics skills and pyramid schemes, which improved their skill level and made the cheerleaders more famous. Later, it developed into a way of competition, which set off an upsurge of student participation in the United States and led other eastern and western countries to follow suit, so cheerleading developed into a worldwide activity. This is the origin of cheerleading.
