On CrossFit and Risk
Growing up, my mom would often tell me “When I was ten, I broke my ankle taking a giant step in the backyard playing a game of SPUD. Heck, if you can break your ankle taking a giant step, you might as well go out and do something more fun.” Fortunately, she has supported me through many such fun experiences over the years. But, like most parents, she has also instilled in me the fact that there is a certain amount of risk associated with doing just about anything in life. The responsibility falls on each one of us to evaluate and decide how much risk we are willing to take on in order to reap the potential rewards of our actions.
I have become increasingly familiar with the concept of balancing risks and benefits through my medical training. Though every medication comes with a laundry list of side effects, and there is risk with “going under the knife” for any surgical procedure, these treatments regularly save lives and reduce the burden of disease. Ironically, the hospital – the place to which we go for life-saving interventions – is also one of the most dangerous places to spend time as a patient. Deaths related to medical errors have been reported at 98,000 – 400,000 per year, the upper limit of which would make preventable medical errors the third leading cause of death in the US behind heart disease and cancer. (1-2) Despite ongoing and diligent efforts to improve patient safety, receiving medical care at a hospital is still accompanied by substantial risk. Yet, in times of compromised health, the potential benefits of hospital care still greatly outweigh this risk.
While preparing for my career in medicine, I’ve also spent the past five years involved in CrossFit. Although I am aware of frequent discussions in the media of its “dangers,” my decision to participate in CrossFit is no different than any other—I heed my mother’s advice and work to reasonably mitigate the risks and maximize the benefits. The benefits of CrossFit are incontrovertible: increased work capacity across broad time and modal domains, in other words, increased fitness. Whether measuring fitness with a maximal effort treadmill test or the ability to stand from a seated position on the floor, it is well-established that increased fitness reduces one’s risk of death. (3-5) In fact, having a better level of fitness decreases your risk of death more than controlling other risk factors such as your blood pressure, cholesterol, and blood sugar. (6) Quite simply, performing constantly varied, functional movements at high intensity (aka CrossFit) will result in increased fitness, and therefore better your chances of living a longer, healthier, more functional life.
