Whenever I think about antibiotics, I stymie my inner Star Wars fan and admit that it’s a good thing the Force isn’t real and Art Ayers is not actually a wizened microbiologist version of Ben Kenobi. Otherwise, he’d be internally wincing every few seconds as another round of antibiotics commences somewhere in the world and a few billion flora cry out in terror and are suddenly silenced, never to be heard from again.
I jest, sort of, but this much is true: every time you take antibiotics, billions of domesticated gut flora die. As I mentioned last week, antibiotics are designed not to target human cells, but the same cannot be said for the commensal bacteria living in our guts. See, most antibiotics don’t discriminate between “good” and “bad” bacteria. They target bacteria. They aren’t us, they are foreign entities, but we wouldn’t be us without them. We need them to function properly. It’s a bit like bringing in an exterminator to kill the bugs infesting your house, and the guy ends up killing your dog and making your cat act funny, along with killing the insects. The job is done, and he technically did what you requested, but now you have to tell your kid that Buddy moved to a farm upstate to go be a sheepdog and figure out how to deal with your cat peeing on the sofa and scratching up your stomach (leaky gut, get it?). Not very fun, and not what you bargained for.
Question: what does your body feel like right now? Go ahead. Take an inventory. From the toes to the head, what’s going on in there at the present moment? How’s your back? How’s your stomach? Your head? How about muscles? Your energy level and mood? Is your thinking clear this morning? Good and bad, what signals are you getting? Beyond the here and now, what’s your body been trying to tell you lately? Any changes since beginning the Challenge? Most important of all perhaps – are you accustomed to listening to what your body has to say?
Everything about our culture, it seems, discourages us from doing just that. From the commercials insisting we don’t need to put up with that headache to the glorification of binge drinking, taking a body’s hint isn’t exactly at the top of most people’s list of talents or priorities. Why live with that pesky fever when you can simply beat it back with 1000 milligrams of extra strength head-in-the-sand? Indigestion from eating that second Big Mac today? Try some Pepcid AC.
The symptoms can be abject misery: searing abdominal pain, debilitating stomach cramps, an excruciating, rising burn, acid-filled hiccups, tightened throat, constant sleep disturbance, and even the rare but terrifying bouts of choking from nighttime acid inhalation. I’m talking of course about acid reflux or GERD as it’s commonly called these days. I personally suffered from occasional bouts of GERD and experienced all the symptoms above for years during and even after my endurance days. (It wasn’t until I gave up grains that my GERD completely disappeared.) Maybe you’ve had it. Maybe you know someone who’s had it. GERD, by the way, isn’t your run-of-the-mill occasional heartburn (which isn’t much fun either) but a chronic pattern of heartburn in which you experience symptoms at least a few times a week. I get emails about it all the time, and it’s little wonder. Statistics suggest that 25-30% of American adults experience GERD related heartburn multiple times a week (PDF). Of all the pharmaceutical categories, proton pump inhibitors (a predominant prescription for GERD) have ranked consistently in the top twenty for years. And that doesn’t even take into account the old-fashioned antacids like Tums and Rolaids that people pop like candy. What, for the love, is going on here? It used to be heartburn was generally confined to women in their last months of pregnancy or to the annual Thanksgiving overindulgence. It certainly wasn’t a chronic condition plaguing a large percentage of the population. I sense a familiar pattern here, no?
If you’ve been paying attention, you’ll know that I’m not a big fan of protracted stretching routines or extended warmups that end up taking longer than the workout itself. I like simplicity. I like cutting corners without sacrificing quality or results. I’m okay with warmups that fulfill their basic goal – getting the muscles warmed up and ready for movement – and with active stretches that move you through the full ranges of motion you’ll be traversing during the workout, but that’s about it. If there was strong evidence in favor of stretching as a protective measure, I would be all over it, because I hate down time. But the latest research indicates that stretching is harmless at best and a performance-detractor if done excessively. Furthermore, warmups, while effective in the right doses, can lead to fatigue and lower performance if overdone.
So what does the research say and what should we be doing (if anything) to prepare for physical activity?
A series of recent studies have implicated sedentary lifestyle in the obesity epidemic. The idea is, even if you hit the gym a few times a week, parking it in front of the T.V. at night dwindles away any benefits gained. Every hour on the couch costs us dearly. But what about the office chair? Dare we take this one on? A recent study does exactly that in targeting the specific role of sedentary work in our nation’s obesity crisis. Our desk jobs, the study’s authors suggest, represent a key culprit behind our society’s expanding waistlines.
Dr. Timothy Church, Dr. John McIlhenny and their associates examined trends related to occupational activity and the corresponding increase in American obesity rates since the 1960s. Fifty years ago, over fifty percent of occupations included moderate physical exertion. Today that number has dropped to less than twenty percent. In keeping with this pattern, Drs. Church and McIlhenny suggest we use, on average, a hundred calories less during a workday than we did fifty years ago. The impact of this change adds up over time – one belt notch at a time.
