I know, I said I would write about physiology next. But that will have to wait just a little longer.

Today’s post will sound like I’m repeating myself, and of course it is a little the case.

In my defense, it is a well-known fact of communication that in order for your message to get through, and for it to be believed, it must be repeated many times. (Preferably by more than one independent “sources,” though that never stopped anyone. Just think of the persuasion success the American leadership had a few years ago about weapons of mass destruction…)

So while I continue learning about physiology (I’m taking an online course, among other things) and clarifying my thinking about how to get that message across effectively, today I’m inviting you to review some recent news items about the importance of fitness for long-term health.

(Added note: I know most bloggers would have split this up in 2 or 3 topics. I’m not most bloggers because I prefer to see things as they fit together, not apart. And I think most people are capable of taking a bit of extra time to read a slightly longer post, instead of three short ones. Like my coaching, my blogging is about quality, not quantity…)

In the News

There has not been anything ground-breaking in the news lately; the artificial conflict between maintaining (or returning to) a healthy weight through diet alone versus exercising more (while being careful what we eat) has been raging. Because most folks on the “food only” side are clearly peddling books and special diets, I’m not even going to talk about what ridiculous stuff has been said on that side of the “debate.”

Instead, you should keep in mind that the best way to increase the odds of being healthy for a long time is through exercising a lot, and being careful about the food (not too much, mostly from plants) we ingest. That’s the “same old, same old” part of my message.

In support of that, you should read an interesting article about how many of the health problems of aging are due to inactivity, not “just” getting old. This is exactly what I mean when writing about muscles being extremely important, not just for metabolic reasons, but to keep bones and brains healthy.

Basically, to be healthy and active well into old age, you need to use your muscles more. The thing is, as one of my favorite authors on the subject has recently added, you don’t even need to do a whole lot in order to reap the benefits. That’s a key point about the approach I embrace and promote: balance is more healthy than excess.

For instance, while I say that we should all move a lot more than we currently do, there are some who say that we should all be training like professional triathletes, 25 or more hours per week. And others say we should not move at all, and instead restrict what we eat in a radical way.

I’m clearly not on the side of diet restrictions without any exercise, and I’ve run ultra-marathons and I do an ironman distance triathlon each year “just to stay in shape,” but even I would not pretend that such a level of training is sustainable for everyone. Although not sustainable, it may be something to shoot for, or, at least, going well beyond the “standard” recommendations of some 150 minutes per week of exercise, remains a very good idea.

Which brings me (finally) to a third tidbit of news about those who have been clamoring that doing marathons and intense training for more than 150 minutes per week were actually causing damage instead of doing good for their health. In light of new research, it seems they are admitting that our bodies can really benefit from a lot more exercise than they previously allowed for.

Moving More, Up to A Point

But keep in mind that, based on the research, there is a diminishing return to be had from increasing the activity level. And at some point, while it may not increase the risk of cardiovascular disease or cancer (which is what the study was concerned with), you up the risk of injury, which is not really taken into consideration from what I’ve read so far.

As reported in Runner’s World:

When mortality rates were adjusted for exercise levels, the researchers found the lowest rate among those who exercised about three to five times the amount recommended by federal guidelines (i.e., 150 minutes per week of moderate exercise, or 75 minutes of vigorous exercise like running). However, the increased benefit of working out three to five times more than the guidelines was modest, the researchers wrote.

More importantly to serious runners, there was no evidence of harm at ten or more times the recommended minimum.

At three to five times the federal guidelines, you are in marathon and short-distance triathlon training territory. Maybe up to a decent half-ironman. Nothing crazy. And sustainable, if part of a lifestyle choice that features living a long and healthy life as its Purpose.

And you can go well beyond that, if you are careful.

Same Old Advice (Summary)

In summary, allow me to repeat what little wisdom I can impart, based on what I’ve learned and what more knowledgeable people have said before me:

1. Move, a lot, because our bodies are at their best when they do.
2. Eat food, not too much, mostly from plants.
3. Obtain, and follow, the advice of a coach (especially if you are going to train seriously for something like a marathon or triathlon (or any endurance- or speed- or strength-focused sport).
4. Steer clear of excess and obsession; strive for balance in all things.

Oh, and I should probably have added “stay tuned.”

Because I’m bound to come back to this subject, and provide more specific advice over time.

After all, much like with training, repetition is what eventually gets the message through… and turns it into a no-brainer.
