A recent New York Times article, Phys Ed: The Best Exercises for Healthy Bones (thanks for passing it along, Mary) declares that “the best exercise is to simply jump up and down, for as long as the downstairs neighbor will tolerate.”
Well…maybe. But who the hell wants to do that?
I’ve said it before, and I’ll say it again. I’m really sick of reporters with no experience in the field having free reign to write whatever they want about health and exercise.
If you read the article, you’ll find that “scientists” are in dispute about how bones respond to exercise, and what type of exercise is best to build bone.
Except, that is, that explosive/heavy weightlifting builds bone well.
But cycling and running are in dispute. In fact, running might even cause the loss of bone, when calcium lost through sweat or in metabolic processes is replaced by bone material.
Wait…hold on reporterer…go back a step…
Explosive movements and heavy weightlifting build bone.
Ok. Well then why the heck aren’t we recommending those activities?
The best thing to do, instead, is to make a joke out of it. “The best exercise is to simply jump up and down, for as long as the downstairs neighbor will tolerate.”
Why make a joke out of it? “For as long as the downstairs neighbors will tolerate?” Why are you jumping indoors? Why aren’t you going outside and jumping? Why are you jumping in place? Why aren’t you running around and jumping onto and over obstacles of varying heights?
That activity also builds the skills of balance and proprioception, which might help to prevent hip fractures even more than the concomitant building of the bone itself! If you never fall, you don’t need rock-hard hip bones.
And that’s not why I have my clients jump, and lift heavy stuff. I’m not concerned with their bone density. That’s a bizarre, reductionist view of the body that I don’t want to buy into.
I have them do those activities because that’s what human bodies are meant to do.
For the last time – YOU ARE AN ANIMAL! You respond best to what all animals best respond to – sunlight, clean water, un-molested foods straight from nature, and lots and lots of physical activity of all types.
The thing all of these “scientists” miss is the big picture – the human body as a whole, as an animal.
If you sit all day, your bones get weak. If you eat a crappy diet, your bones get weak. If you run for a long time, and don’t replenish the nutrients you’ve lost, your bones get weak. Cycling isn’t even a weight-bearing activity, so I’m not sure why the article focuses on it so much…
Also, in response to one of the comments made by a researcher quoted in the article, I’m pretty sure there’s been research that shows that calcium lost during endurance exercise is compensated for by bone if it’s not replaced soon. I’ll have to double-check that. I wouldn’t be surprised, though – most researchers are so caught up in trying to keep grants rolling, etc., they don’t even know the research that has been done in the area they themselves are studying.
Which speaks to another issue I have with this type of reporting. Science is a process of exploration. It is curiosity. It is asking questions and trying to find the answers.
IT IS NOT THE PLACE OF SCIENCE TO MAKE RECOMMENDATIONS.
We put science in such a place of authority in our country that brains shut off like lights in a blackout. I can see them all the way down the street, blinking off. No thinking required. Science has me covered. The scientists will tell me the right thing to do. The government will talk to the scientists and protect me.
Bullshit. Turn your brain back on.
I take such offense to this, because people who don’t know any better are going to read this article, and others like it.
What is someone going to do who reads this article? They’re going to say, “oh to hell with it…exercise isn’t helping my bones…” or “I need to jump up and down more!” Which is silly!!! I mean, if you’re just jumping up and down in place…ridiculous. See the above comments about balance and proprioception and nature and the requirements of a healthy animal.
And what about the bones in your arms? How do you get those stronger? Jumping up and down doesn’t put any strain on your arms.
How about crawling? Explosive pushups? Heavy bench pressing?
Oh no…we shouldn’t do that! Let’s just play patty-cake until the downstairs neighbors complain!
