Cheerleaders are part of athletic competitions throughout the United States. They lead the crowd in cheering for the team it likes best. Most cheerleaders in the early years were men. That changed during World War II, when large numbers of young men left the country to fight. From that time on, more than 90% of cheerleaders have been female. Today most American high schools include cheerleading among their student athletic activities. The cheerleaders must be in good physical condition. They must be able to jump high, turn circles in the air and lift each other. Many girls attend cheerleading camps in the summer to improve their skills and learn new moves. Some people say cheerleading is not a sport because it does not have unified rules. Rules for competitions among cheerleading teams are different, depending on the group organizing the contest. However, cheerleading is an athletic activity requiring physical skill, and cheerleaders add to the excitement of an athletic event.
