Cramps - I Believe in Santa Claus

The question of cramping came up in a chat session with some running enthusiasts the other day, and pickle juice was mentioned as a possible solution to the problem. I guess I would have laughed a little more loudly if I hadn't read the same thing in a recent edition of Outside magazine.

Most runners or athletes have had a muscle cramp at one time or another, and we can all agree they are no fun. Somehow we manage to endure the pain and try to go on. And everyone has an opinion on what to do in order to keep the cramp from happening. I've heard people attribute cramps to dehydration, electrolyte imbalance, glycogen shortage and a host of other possibilities. I have a couple of suspicions myself, one of which involves the chairs at the Village Inn restaurants.

I kid you not.

It doesn't matter if I've run an easy five miles, or completed a hard speed workout, or gone to the pool for a masters' swim. Within five minutes of sitting down for a meal at the Village Inn it's guaranteed I will have a massive cramp in one or both of my hamstrings. And we're not talking the 'ouch, that's a cramp,' cramps. I'm talking about the type of cramp which is able to literally pitch a guy off the side of the chair and on to the floor. The type of cramp which makes grown men cry like seven year-olds who have just been told Santa Claus is fiction.

So now I sit at a booth. And I still believe in Santa Claus.

The Outside magazine piece took on several commonly-held beliefs about exercise and physical activity. When it came to the subject of cramps, runners have been told by the running cognoscenti they were caused by dehydration. Other smart people said the cramps were caused by a lack of electrolytes. Some even hold on to the belief that a lack of fuel (glycogen) is the cause.

I'm one of those who considers the fuel theory of cramping to be a strong possibility. It stems a great deal from what I've read of the Central Governor Model for Exercise, originally written about in the 1920s by Nobel laureate Archibald Hill and expanded on by physician, physiologist, marathoner and ultra-marathoner Dr. Timothy Noakes about ten years ago. Noakes' theory says, basically, our brain pretty much calculates a safe level of exertion based on past exercise experiences, metabolic state, and the intended duration of the exercise activity.

For those of you who might remember the old Star Trek series, exercise is like having the Enterprise getting hit with photon torpedoes and taking on damage. And, naturally, Captain Kirk would tell Mr. Scott in engineering to shut down everything except for life support. Okay, I'm glad we kept life support up. Duh.

Noakes writes that our central governor is going to hold back fuel (glycogen) to keep the heart, brain, and lungs alive, shutting down the fuel source to muscle fibers here and muscle fibers there. That's the reason fatigue sets in, our stride gets choppy and our range of motion decreases. Once more fuel comes to play, or the exercise bout ends, the brain recognizes the threat is over and returns (eventually) to normal function - homeostasis.

This old coach's take? The cramp either comes along because of too many muscle fibers being shut down, or from some sort of nerve-related thing (in my own personal case with the Village Inn chairs, pressure).

So why does ten milliliters - less than three ounces - of pickle juice seem to take care of cramping? Some think it has to do with a quick burst of electrolytes. Others think the tart, salty taste of brine causes a disruption in the nervous system...confuses the nerves.

A fitness enthusiast (who just happens to sell an electrolyte balancing beverage) believes the cramp comes as a result of an electrolyte imbalance. Sodium contracts muscle cells and potassium relaxes them. Calcium signals the sodium ion channel to open to begin the contraction cycle. Magnesium then encourages potassium to rush in which relaxes the cell. When a cramp happens, it’s the elements in charge of the relaxing half of the cycle, magnesium and potassium, that are missing.

Pickle juice is predominantly vinegar, which is another form of acetic acid. Acetic acid is used to treat individuals with high blood sodium levels. So, in the mind of this person, lower the sodium level in comparison to the potassium, and you may not begin the cramp.

But Schwellnus, Nicol, Laubscher, and Noakes found in 2004 there were no significant differences between two groups of ultramarathoners - those who cramped up during a race, and those who did not - for pre-race or post-race body weight, percent change in body weight, blood volume, plasma volume, or red cell volume. The immediate post-race serum sodium concentration was significantly lower in the cramp group than in the group which did not suffer from cramping. The immediate post-race serum magnesium concentration was significantly higher in the group of runners who suffered from cramping. There also were no major differences in hydration status in runners who suffered from cramps after participating in an ultra-distance race.

The cause of exercise-associated muscle cramps is probably a little closer to our brains and our nervous system than we care to admit. We might be able to drink it away with pickle juice, but all of the preventatives are more myth than truth.

I believe in fuel, and I still believe in Santa.

Back To Basics, With Friends

“Life is partly what we make it, and partly what it is made by the friends we choose.” - Tennessee Williams (1911-1983)

In my former life, I worked as a performance technologist. The goal of that work wasn't much different than what coaches do, except I was less teacher and more troubleshooter. Most of that time - when not (desperately) searching for projects - was spent identifying barriers to optimal performance in the workplace. I've talked about the categories of barriers in the past, especially when looking at injury causes (the five "whys?"), so I won't do that now.

My employer decided to transition to Lean Six Sigma a couple of years ago. At the surface it's continuous process improvement like performance technology, except the focus is more on the product and the process and less on the worker. The worker is important, but the view of the big picture comes down to value. If a function provides no value for the company it's likely going to be pared away, cast aside or lowered in priority.

My wife and I talked about Lean this morning, especially priorities and work tasks. I reminded her if a task had nothing to do with what brought income or customers to the business it was probably a waste of time. Naturally, with every rule there exists an exception: There are some things we do which have little to do with core functions. The utility is based on our enjoyment or it strengthens a relationship.

A good example comes from my experience with the Emerald Coast Racing Team: It started as a weekly dinner and chat with my coach and his wife. What began as a nice, quiet evening out at the local pizza pub between the four of us spun into up to a dozen team members quaffing beer and cracking jokes on Friday evenings. The socials took on a life of their own and became more popular than the Tuesday and Thursday night workouts.

When a person who hadn't been to a track workout for three months asked where we were going to meet on Friday night I knew it was time to put the social aside for a time. Not long after that I also stopped booking hotel rooms for road trips when friends of those "once-every-three-month" members "desperately" needed a room. Too much trouble; not enough good karma coming back to me. To borrow from Leonard "Bones" McCoy of the "Star Trek" television programs/movies, 'I'm a running coach, not a social coordinator.' I lost some potential clients but the decision allowed me to return to the basics of coaching runners.

I've a small group of fairly dedicated runners this year, and the coach-athlete relationship over time has developed also at the friendship level. It's easier to speak to a friend in very honest terms, especially when "under-the-surface" issues stand in the way of a good race performance. Not that it's happened with this group, but it's nice to know the conversation goes both ways; sometimes in a tone which could send a "customer" off to patronize another coach.

After a workout about two weeks ago, my wife, Suzanne, mentioned about how we used to meet at a local barbecue restaurant after Tuesday night workouts. We all felt it was a great idea - I'm rarely in a rush to go home immediately after a good workout - so we started to talk about what we wanted. What were the basics we needed for a post-workout meal?

We've eaten in places which were a little crowded, with other patrons watching "Dancing with the Stars" who definitely were not thrilled in the slightest to share their evening with the endorphin-fueled quacking of a half-dozen runners. So, we knew we wanted something a little on the laid-back, runner-comfortable side of the spectrum. We all live anywhere from 15 to 20 minutes away from the track, so we did not want to inconvenience anyone too much by a location too far one direction or another from the track. We suspect we have found that "80-percent solution," a place which lets us blow off a little steam, have a beverage and a bite to eat before we go home to continue our recovery in earnest. And if it doesn't work for us we'll scale it back or find another place at which to decompress.

The best part of group training is - at its most basic - the ability to suffer through together; to pull and be pulled through by each other. And, when it's all over, the chance to laugh about how you somehow made it through.

Timothy Noakes and the Ferengi Rules of Acquisition

There was a time, just before I started college, that I started to watch Star Trek: The Next Generation & (to a lesser degree) Star Trek: Deep Space Nine. It came on just after the local news; this gave me the chance to unwind after an evening run. Since my friend John (and his wife Terri) had a nice television (Anything larger than the 12-inch diagonally-measured black-and-white I had at that time in my little apartment met the definition of nice.) at their apartment, they would graciously invite me over for an O'Doul's or a white zin spritzer, & we would watch one or both of the ST series episodes, depending on the day of the week.

I thought ST: TNG was the better of the two series, but there was something entertaining about ST: DSN.
As a guy with an all-too-rigidly-defined sense of right-and-wrong, I found the Ferengi both abhorrent & attractive. For 18 months between my sudden social shake-up & going to college, I had a former roommate, a one-time grad assistant/fervent left-winger/lecturer/small-time con artist/educational fraud-enabler at the University of Arizona. We spent evenings discussing ethics, philosophy, economics, history & political science over coffee or dinner, either at the local Shoney's or on the back porch of my apartment. I absorbed the equivalent of a freshman-year education during that time, for free...it cost his share of the rent.

Discussion topics ranged from existentialism (once you understand it you see it in everything) to what can best be described as the economics of the street. Of course, when you've had a Manichaean black v. white, good v. evil mindset drummed into you from childhood & further beaten into you by fundamentalist preachers, there are certain moments which can be quite liberating. Nietzsche's beyond good & evil, master mentality v. slave mentality, for example. However, you don't have to read Nietzsche to understand Nietzsche. Just look for old Star Trek: Deep Space Nine episodes. The Ferengi are Nietzsche reincarnated.
I used to love the Ferengi Rules of Acquisition. My buddy used to laugh at me because I had a rigid, methodical approach to everything in life. (I was a Methodist for many years. Sue me.) He used to joke about the Tao of Bowen: Follow sidewalks rather than cut across grass, stuff like that. Even my wife figured I have this tendency to calculate, & try, much like Emanuel Kant, to live my life as though a universal rule should be written by it (what Kant called the categorical imperative). Until this morning I wondered if ANYONE wrote down or collected the ROA for the benefit of fanatics (lunatics?) like me.

So, I was at the track last night...we were finishing a particularly ugly workout when my friend Larry S. finished his warm-up jog. We chatted about training, & he asked my opinion about a particular long-distance training program. (Naturally, I've got opinions. If I didn't I wouldn't be writing here, right?) I told him what I thought was the dirty little secret about the plan, then provided him a recommendation of my own, based on his goal...which I learned was completing an international distance (otherwise known as Olympic-distance) triathlon. Larry trains with me when his work schedule permits, & he's a good soul, so I do not hesitate to give him my wisest counsel...which, of course, he can ignore at his peril or use...& more than likely do well. Ferengi Rule of Acquisition #284: "Deep down everyone's a Ferengi."
Larry was going to use a marathon training plan as the run training portion of his triathlon prep. Since Larry's doing an international distance event, I felt a marathon plan would put too much run training volume into his training. After doing a quick crunch of numbers, I estimated he would do 50 minutes for ten kilometers of running, 75 minutes for 40 kilometers on the bike, and 18-to-20 minutes on the swim. So, nearly two & a half hours at race effort? I believe he needs little more than to be able to run a decent half-marathon at the worst. Maybe somewhere less, but definitely more than a typical ten-kilometer training plan, and definitely less than a marathon, since he's going to be fatigued from the bike by the time he starts the run.

Why did I provide Larry that counsel? Timothy Noakes' Law of Training, #6: "Achieve As Much As Possible on a Minimum of Training."
Too many athletes, especially ones whose goal is to finish the event, do too much training. The law of diminishing returns, especially in run training, has sharp teeth. It doesn't hurt to know your own physical limitations: If you try to run marathons & the training volume kicks your @$$ (which it has done to me two times out of three), it might be the Almighty's way of trying to tell you to try half-marathons instead...or to find a training program with less volume.

Yeah, there are other factors, too, but you have to know what your body can - & cannot - handle. And in closing, let me remind you of Ferengi Rule of Acquisition #44: "Never confuse wisdom with luck."
