Cheerleading was considered one of the most dangerous sports, but rules changes have resulted in a steep decline in catastrophic injuries. File/Andrew J. Whitaker/Staff

Many comments I receive when I write about sports injuries and strategies to prevent them are similar to this one.

“I appreciate you bringing attention to these injuries, but sports are dangerous. Injuries are going to occur. Every athlete who steps on a field or court knows there is a risk of getting hurt. We need to stop adding rules that change these sports and make the athletes soft and just let them play.”

I understand the sentiment. In some cases, I’ve questioned the logic of a specific rule and whether it actually protects the athletes, such as the new “roughing the passer” rule adopted by the NFL prior to this season.

The reality of sports, though, is that they can lead to more serious injuries than sprained ankles and sore knees. Some athletes suffer injuries that cause lifelong pain that makes it hard to work, exercise, and lead a normal life. In some cases, sports can lead to death or paralysis of an athlete.

In this last category of injuries, we can show that efforts to prevent injuries have made a real impact.

Let’s go back about a decade. A 2010 ABC News headline read "Most Dangerous 'Sport' of All May Be Cheerleading."

“They make you sign a medical release when you join a cheerleading team. They ought to tell the girls that they are signing a death waiver," claimed a cheerleader quoted by The New York Times in a 2007 story.

The Washington Post published a story in 2013, using data from a 2012 statement by the American Academy of Pediatrics, showing how cheerleading accounted for 65 percent of all direct catastrophic injuries to female athletes at the high school level and 70.8 percent at the college level between 1982 and 2009.

We define a catastrophic injury as one that causes permanent spinal injury and paralysis. Among female athletes, cheerleading did account for a huge percentage of these injuries. Between a few athletes who died and a small but significant number who suffered neck and back injuries that left them paralyzed, cheerleading received quite a bit of unflattering media attention.

Starting in 2002, the American Association of Cheerleading Coaches and Administrators (AACCA) and National Federation of State High School Associations (NFHS) implemented several rules changes to make cheerleading safer. Most notably, prior to the 2006-2007 academic year, the AACCS and NFHS banned basket tosses on hard surfaces like basketball courts at both the high school and college levels.

A basket toss involves multiple cheerleaders locking hands to toss another cheerleader high into the air.

A study recently published in the journal Sports Health shows that these efforts made a real difference. Dr. Rebecca K. Yau and others analyzed cheerleading injury data collected by the National Center for Catastrophic Sport Injury Research from July 2002 to June 2017.

Basket tosses did prove to be the stunt that accounted for the highest proportion of injuries. The rate of catastrophic injuries decreased dramatically after the 2006-2007 rule change that banned basket tosses from being performed on any hard surfaces. In fact, the researchers observed a  74 percent reduction in the rate of catastrophic basket toss injuries.

Cheer experts and leaders recognize that more work is needed to decrease the risk of injuries even further.

The problem for most sports fans – football fans mostly – who feel that sports and medical experts are going too far in changing the rules is that there is rarely one clear risk like the basket toss in cheer.

Maybe eliminating kickoffs in football could decrease concussions significantly, but other changes might only decrease injuries a small amount. Adopting a large number of rules changes over time could lead to a large overall injury reduction, but the effect of those rules might have fans of the sport complaining about what they see on the field.

Plus, in sports like football and boxing, their fundamental activities – tackling and punching – make dramatically decreasing injuries almost impossible without radically altering the nature of the sports.

The process used by the AACCA is one we must continue to use in all sports. Use data to identify the problem. Take steps to eliminate or decrease the risk of injury. Collect many years of data, and then assess whether the strategy effectively lowered the risk.

Cheerleading is on the right track. Let’s continue to look for similar prevention strategies for athletes in all sports.
