Saline Chronicles: What Does It Mean To Be Fit?
One of my father’s favorite sayings was, “I’m in pretty good shape for the shape that I’m in.” He was being funny of course, but these days, I can totally relate. It’s all about perspective. Today, I’m thinking about what it means to be “fit” as I walk at a snail’s pace on my treadmill and suck saltwater into my lungs, which are being violently shaken by my therapy vest.
If you use the biologic definition of fitness,
The genetic contribution of an individual to the next generation’s gene pool relative to the average for the population, usually measured by the number of offspring or close kin that survive to reproductive age.
then I’m toast. These genes were surgically stopped in their tracks decades ago. On purpose.
If you get a bit less Darwinian, fitness could be described as:
The capability of the body of distributing inhaled oxygen to muscle tissue during increased physical effort.
This is getting closer to what I’m after. But living with cystic fibrosis takes a special kind of fitness not intimated by either definition. My favorite description of fitness is one I heard on a podcast yesterday, which was something like,
The ability to do what you need to do, given the exigencies of your life, and to have a little left over for emergencies.
In other words, to be in good shape for the shape that you are in.
The “exigencies” of our lives include things like constant immunological battles in our lungs, defective insulin production, and shitty (pun intended) digestion, to name a few.
To be fit with CF means to be able to thrive, given all of these complications…and then, to have something left should an emergency occur.
I have a CFit client who is a perfect example of CF fitness. This woman is a runner, and also lifts weights and dabbles in Crossfit. She’s hardcore. She related a story to me the other day which left me amazed.
She was running with a group of people crossing a bridge, when they noticed a child stuck on a log in the water below. This was in Florida, and the water was swampy and apparently the home of many crocodiles. The kid was unable to swim to safety, and was in a precarious position, to say the least.
So my client took off at a sprint, as she needed to run nearly a mile to get to where she could enter the water. Then, she had to swim to the kid and keep him/her (I’m not sure) from being swept into crocodile territory until help arrived.
Now that is fitness!
If you are reading this thinking, “that could never be me,” you are missing my point. If you have CF and are simply moving more each day in attempt to improve your health, then you are an athlete in training. You don’t need to be a child-rescuing ninja. If you don’t like to run, then walk, or swim, or cycle, or lift weights, or swing a kettlebell, or play badminton, or… something! Prepare for that emergency. It may be a kid in danger, but more likely, it’s the next exacerbation. Whatever it is, it will be in your best interest to be stronger than you are right now. Unless you are my ninja CFit client…she’s already in pretty good shape for the shape that she’s in.
