Exercise Risks and Rewards: Is CrossFit Safe?

is CrossFit safe

By now, you’ve probably seen (or at least heard of) some of the horrible videos of people supposedly being injured while doing CrossFit. You may have even heard of Kevin Ogar, a top CrossFit competitor who became paralyzed after making a mistake during a snatch lift in a January CrossFit competition. Ogar’s case, along with the many negative videos and stories, has many people asking, “is CrossFit safe?” The problem with stories like these, however, is that they’re precisely that: stories. People who claim CrossFit is unsafe are often pointing to anecdotal evidence as opposed to real, scientifically confirmed data. Unfortunately, the only studies available on the subject are small or inconclusive. Proponents of CrossFit seem to tout it as the most effective exercise program, while opponents are adamant that other programs work just as well with less risk. Who’s right?

Workouts and Surrounding Culture are Intense

For those unfamiliar with CrossFit, it’s a high-intensity interval training program similar to P90X or Insanity. Founded in 2000, CrossFit combines powerlifting, gymnastics, calisthenics, olympic weightlifting, plyometrics and several other exercise strategies into rigorous daily workouts. CrossFit allows for rapid weight loss and muscle gain. Over 10,000 gyms in the U.S. now offer CrossFit workouts, which often make use of barbells, gymnastic rings, kettebells, medicine balls, jump ropes, resistance bands and several other pieces of equipment. Gyms that participate in CrossFit are known as “boxes,” and the classes usually consist of hourlong sessions including a warmup, the high-intensity “workout of the day (WOD),” and stretching.

It is perhaps the culture of CrossFit that many point to when explaining their derision. CrossFit instructors only have to pass a two-day training session before becoming certified as a Level 1 Trainer. While this isn’t exactly unusual when it comes to exercise programs, it does cause some to question the credibility of CrossFit when considering how intense and varied the workouts are. It could be argued that many instructors might not know when they’re pushing exercisers too hard. Also, CrossFit workouts encourage competition. WOD performance is ranked and scored, fostering a culture in which exercisers strive to constantly improve their performance and overcome their peers.

Lastly, two horrible “unofficial mascots” – Pukie the Clown and Uncle Rhabdo – are certainly not doing CrossFit any favors in the reputation department. Pukie refers to the tendency for some exercisers to vomit from the intensity of the workout – this is even considered a rite of passage by some. Uncle Rhabdo refers to a rare but very serious condition known as Rhabdomyolysis, in which damaged muscle tissue breaks down and ends up in the bloodstream. Rhabdomyolysis can lead to kidney failure and even compartment syndrome, which in turn can necessitate surgery to relieve pressure in swollen muscles.

Studies Are Inconclusive

There are only a few studies that have tried to answer the question of “is CrossFit safe?” The first one, conducted by researchers at The Ohio State University, concluded that CrossFit is very effective. It states, “Our data shows that HIPT [high intensity power training] significantly improves VO2max and body composition in subjects of both genders across all levels of fitness.” However, another line in the study has created serious concern about injury. It claims that 11 people did not complete the course, nine of which cited overuse or injury. This is significant because there were only 54 people in the study, meaning that 16 percent of participants suffered an injury.

The owner of the gym has since questioned the validity of the study, claiming that participants were not actually interviewed as to why they didn’t complete the program. In fact, the owner is going so far as to actually sue the researchers, creating a somewhat unprecedented situation.

The results of the second study are much more forgiving. According to the data collected, CrossFit has an injury rate of about 3.1 per 1000 hours trained, and no cases of rhabdomyolysis were reported. This means that “is CrossFit safe” could be answered with, “about as safe as gymnastics or powerlifting.” In fact, this injury rate is lower than what’s seen in some versions of rugby. On the other hand, the data was collected using an online questionnaire, which leads to all sorts of doubts about the credibility and precision of responses.

Is CrossFit Safe: The Bottom Line

“Is CrossFit safe” is a question with no easy answer. The research just isn’t definitive either way. However, it must be remembered that any physical activity can lead to injury. Exercisers constantly risk injury in order to improve their bodies. Also, it’s been proven that CrossFit really does get results. So, it’s up to each person to simply dedicate themselves to the program while approaching it with safety in mind. Here’s what we advise when beginning CrossFit:

  • Check Out Your Instructor – Find out as much as you can about the person leading CrossFit classes at your gym. How much training do they have? How long have they been teaching CrossFit? Are they certified in other areas? Have a conversation with them and make sure they never try to push people past their limits. Speaking of which…
  • Know Your Limits – The competitive nature of CrossFit could potentially lead some overzealous exercisers to push themselves too far. If you’re exhausted or feel that you’re doing things incorrectly, swallow your pride and stop. Pushing yourself gets results, but you must listen to your body.
  • Not For Beginners – While some proponents of CrossFit maintain that the first level of the program is safe for beginners, you simply can’t get off the couch and start doing it. It’s important to get some slow, considerate training in the proper use of exercise equipment and weights first. Beginners should be comfortable with regular aerobic exercise before trying CrossFit as well.
  • Get Professional Help – A doctor and/or personal trainer can help you decide if CrossFit is right for you and can evaluate its effectiveness as time goes on.

It’s important to note that this advice is useful for any fitness program. However, it might be even more crucial when it comes to CrossFit, if for no other reason than to avoid being the next “CrossFit fail” on YouTube.

  140. There are incredibly a lot of details like this to take into consideration. Which is a great point to raise up. I provide thoughts above as general inspiration but clearly you can find questions such as one you start up the place that the most crucial thing is going to be getting work done in honest very good faith. I don?t determine if guidelines have emerged around stuff like that, but I am certain that the job is clearly identified as a fair game.

One other stuff I would like to talk about is that there are lots of games that you can buy which are designed in particular for toddler age little ones. They consist of pattern acceptance, colors, family pets, and shapes. These typically focus on familiarization as opposed to memorization. This keeps little kids occupied without having a sensation like they are learning. Thanks
