A Competitive Sport

Over the years, cheerleading(啦啦队) has taken two primary forms: game-time cheerleading and competitive cheerleading. Game-time cheerleaders’ main goal is to entertain the crowd and lead them with team cheers, which should not be considered a sport. However, competitive cheerleading is more than a form of entertainment. It is really a competitive sport.

Competitive cheerleading includes lots of physical activity. The majority of the teams require a certain level of tumbling (翻腾运动) ability. It’s a very common thing for gymnasts, so it’s easy for them to go into competitive cheerleading. Usually these cheerleaders integrate lots of their gymnastics experience including their jumps, tumbling, and overall energy. They also perform lifts and throws. This is where the “fliers” are thrown in the air, held by “bases” in different positions that require strength and working with other teammates.

Competitive cheerleading is also an activity that is governed by rules under which a winner can be declared. It is awarded points for technique, creativity and sharpness. Usually the more difficult the action is, the better the score is. That’s why cheerleaders are trying to experience great difficulty in their performance.

Besides, there is also a strict rule of time. The whole performance has to be completed in less than three minutes and fifteen seconds, during which the cheerleaders are required to stay within a certain area. Any performance beyond the limit of time is invalid.

Another reason for the fact that competitive cheerleading is one of the hardest sports is that it has more reported injuries. According to some research, competitive cheerleading is the number one cause of serious sports injuries to women. Emergency room visits for it are five times the number than for any other sport, partially because cheerleaders don’t use protective equipment. Smiling cheerleaders are thrown into the air and move down into the arms of the teammates, which may easily cause injuries. Generally, these injuries affect all areas of the body, including wrists, shoulders, ankles, head, and neck.

There can be no doubt that competitive cheerleading is a sport with professional skills. Hopefully, it will appear in the Olympics since cheerleaders are just as athletic and physically fit as those involved in the more accepted sports. It should be noted that it is a team sport and even the smallest mistake made by one teammate can bring the score of the entire team down. So without working together to achieve the goal, first place is out of reach.
