Fitness Quest: The Consequence of Measuring Muscle Mass

So, in my constant quest for greater fitness I thought it might be fun to engage a couple friends in a challenge to see who could lose the most body fat in the next few months (by the start of spring).  I decided that I should switch out my trusty Tanita scale that I’ve been using for some years with a Taylor scale that I’ve also been using on and off (to paraphrase that old saying: a man with one scale knows how much he weighs, a man with two is never sure). The reason being because though both scales measure body fat percentage – and are pretty close in their measurement – the Taylor scale has a few more

features including a calculation of hydration and muscle mass, all of which are uploadable into an app for easy tracking. For the challenge we have decided to use waist/hip ratio as our measurement tool, but I thought I’d follow my progress on the scales, too. Since I do weigh myself everyday anyway.

The “new” scale works nicely and as I said the body fat percentage corroborates with the other scale. But, today I took note of the other measurements. Fat mass was where I expected at about 25% (needs to be under 20), body water at 59% – a little dehydrated which isn’t surprising since my colon isn’t there absorbing water anymore since my ileostomy – and my muscle mass was at just over 30%. Now, you’ll notice that these percentages added together total more than 100%. I haven’t found it in the documentation yet, but I suspect that the body water figure is independent of the other two and is calculated off the remaining body mass (organs and skeleton). So, based on these readings my body is a little over half fat and muscle. So far so good right?

Well, I then wondered how my muscle mass compared with the average guy – you know, because we guys are all about measurements and comparisons with other men (to prove we’re better). Since I’ve been working out I’ve always assumed that I had more muscle

mass than most men. I know that my arms are larger, even now in their “depleted” state (a little over 15″ in circumference compared to the average untrained American male who is around 11″) they do flex and do not jiggle when I move them. I once benched 350 pounds and still am capable (I think) of a one time max of more than my bodyweight. Good for anyone, great for a man of my “advanced” years. Plus, you know, I have done squats in the past, too keeping my lower body pretty fit – even with too much fat around the hips (you should see the definition in my “marching band” calves).

So off to Google I go and search for “how much muscle does the average man have” and imagine my surprise to find out that according to my scale I not only have less muscle than the average man (about 60 pounds compared to livestrong.com’s average of 72 pounds).  I thought, “okay, but surely my percentage is higher.” Nope…

Not only am I low for the average man, I’m low for a man my age and older! How is this possible? I was only in the hospital for a week and recovery for six weeks. Can muscle mass be lost that quickly?

Now, I did come out of the hospital 20 pounds lighter than I went in. This would equate to a loss of about 2 pounds a day for my 10 day stay, but most of the weight loss was early. I never figured out why it was so much, as I doubt that a meter of intestine (the full length of my ileum) weighs that much since it’s essentially a hollow tube of muscle and skin. Maybe it was because of all the stuff that was leaking into my abdomen was no longer there, a lot probably water weight, and maybe an incidental “liposuction” when they cut through the fat and muscle to get to my innards. I just didn’t know. However, I felt that when I cam out that my chest and shoulders had disappeared on me. Could I

really have lost that much muscle that quickly? Or is my scale wrong. Did one operation undo 30 years of weightlifting and bodybuilding?

I think it will be interesting to see what happens over the course of the next few weeks and months as I continue into my workout routine. I will admit that I wasn’t doing a lot prior to the operation but I was lifting twice a week and getting in some cardio. Plus, there was the cardio rehab I had just finished earlier in the late spring. Muscle memory is a wonderful thing, but we all know that as we get older we don’t bounce back as quickly as we did before.

In fact, most studies indicate that as we age we lose a significant amount of muscle with some, if I recall correctly, suggesting men lose as much as 10% of their muscle mass for each decade after 40 (or earlier). Most studies also suggest that this loss is as much due to inactivity as anything as we tend to move less as we get older and that working out becomes less of a priority when family and career get involved (thus the rise of the so-called “Dad Bod” someone with some muscle on them but it’s covered in a layer of fat).

However, there are also studies that suggest that this muscle loss can be slowed if not completely reversed. That, contrary to popular belief, even people in their eighties and nineties can gain muscle. Maybe not as fast as in our youth, but gains can be made. In fact, I feel that I was at my strongest in my mid to late forties. Not necessarily my fittest, just my strongest.

Which bring ups an interesting tangent. I had a conversation recently with a young man who I’ve befriended at work. He’s a bodybuilder (though I don’t think he would consider himself one since he lifts primarily for “fun,” but I’ve seen his before pictures and he’s clearly a bodybuilder) and he asked me an interesting question: “do you know how men keep getting stronger as they get older?” I replied that I had noticed the same thing myself, stating that many bodybuilders seem to hit their prime in their thirties and how I felt I gained strength well into my forties. But he then said, “no, do you know HOW men keep getting stronger?” and I indicated that I wasn’t sure, perhaps the body doesn’t actually fully mature until a man is in his twenties or later.

Now, I think I can answer that question a little better. Men who keep getting stronger as they age also don’t give up. They stay focused on being a little better each day, at lifting a little more, running a litter farther.

Basically, men get stronger as they age because they think they can.

I think that I can, too. The best is yet to come.

Onward.
