Injuries

 Jersey City Liberty (2012) mentions how cheer leading competitions can get very competitive. So competitive in fact that people's muscles stiffen up. Which then causes people to fall and then it can lead to very serious injuries. Some injuries may even lead to surgery or serious consequences.

 Emergencies (2012) states how most of the patients that visit the hospital are athletes.Twenty-seven percent of the athletes that visit the hospital are known to be cheerleaders. The rest of the percentages vary between different sports. Competitiveness is very big in cheer leading competitions so if you're in one be careful!
