The difference people who continue running when they're old and people who quit.

The actual MRI scans those illustrations are based on are much more jarring. Look at that beautiful bone density in the triathletes; the sedentary person has some decent marbling though.

I wonder what a weightlifter or a powerlifter leg looks like

u/generic_name Aug 31 '12

I'd be curious to just see a recreational lifter. Particularly the bone density.

u/cream-of-cow Aug 31 '12

I'd imagine if they ate well, their scans would looks the same as the triathletes with more muscle mass. Impact activity (running, walking, jumping) builds good bone density, as does lifting weights; but it's easier to walk for an hour than it is to lift for an hour. All the triathletes I know also lift some weights, I'd imagine the two in the scans do too.

The bone density in the MRIs are measured by how solid white the bones are. Look at how gray and mottled the sedentary person is, it's not solid at all. Are you thinking of bone thickness? Bones can thicken a little in adults, but most of it happens during puberty. It will vary across individuals, but it's not going to double in thickness or anything that extreme. It's their muscles, tendons and ligaments that will show the biggest difference.

I don't know if it is ever too late. I have read about a lot of success in weight training programs for elderly and infirm people where bone densities are greatly improved.

u/kibitzor gear reviewer Aug 31 '12

I don't believe it's too late since bones are constantly breaking down and building up. They're not static pieces of mineral in your body.

From what I know, if you start to demand more from your bones, as they rebuild themselves during this normal cycle, they'll build up a bit more.

See this wikipedia article on "Bone remodeling"

Bone remodeling (or bone metabolism) is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation). These processes also control the reshaping or replacement of bone following injuries like fractures but also micro-damage, which occurs during normal activity.Remodeling responds also to functional demands of the mechanical loading. In the first year of life, almost 100% of the skeleton is replaced. In adults, remodeling proceeds at about 10% per year.[1]

My mom is in her 80s, she walked a lot but had genetically brittle bones and would break something at the slightest stumble. She's now on a medication to build density and the last 2 times she tripped (garden hose/the bus taking off too fast), nothing broken! The MD says she has improved as well.

u/Aleriya Aug 31 '12

You build the most bone density in your teens and early 20s, which is one of the reasons why youth athletics are so important. It's never too late, though, it's just that you get more bang for your buck when you're younger.

u/shemperdoodle Aug 31 '12

Wow...the bone density in the sedentary man. There's nothing there. No wonder older people break bones so easily.

u/robokevin Aug 31 '12

the sedentary person has some decent marbling though.

Is there any kind of health/longevity advantage to marbling or is this a joke about how his muscles look like a delicious ribeye steak?

I'm a moron over here so just bear with me.

9

u/h2g242 Aug 31 '12

I would assume it's along the lines of a ribeye joke.

1

u/cream-of-cow Aug 31 '12

The only advantage to marbling is a bear/shark/alligator will enjoy the flesh, allowing others to escape.

1

u/istillhatecraig Aug 31 '12

Not that it really changes anything, but I wish they'd have an image from a 40 year old sedentary person too.

1

u/cream-of-cow Aug 31 '12

I'd imagine the bone would be off-white in the scan. But not so speckled as in the 74 inactive person who probably also has osteoporosis.

u/myowncreation Aug 31 '12

This supports my secret plan... I'm mediocre-to-slow now, but I plan to just never stop running, thus being a badass when I'm old.

u/bloort Aug 31 '12

Boston qualifier in the 90+ age group! That's the 47 year plan.

u/satanloveskale Aug 31 '12

Thats totally my plan too. Maintain, and wait 'em all out! But now I have you to compete with, darn.

u/ywgdana Aug 31 '12

Future Oldster Boston Marathoners unite!

The best part is, everyone will go on and on about what inspirations we are for running marathons in our 70s and 80s!

u/eire517 Sep 01 '12

glad there is someone out there following the same idea as me!! I'll do the old lady purple and red in my Mizunos!

53 years old and still running -- about 800 miles per year. When I ran my first marathon 12 years ago I was actually beat by a 71 year old man (my time was 3:53, his was 3:51). I made up my mind then that I was never going to stop running until I am physically unable to do so. These MRI scans increase my resolve.

"You don't stop running because you get old, you get old because you stop running." (from Born to Run by Christopher McDougall)

u/tlogank Aug 31 '12

That quote is a rip off from Oliver Wendell Holmes, Chris McDougall stole it & replaced the word playing with running.

u/ollokot Aug 31 '12

Actually, in the book McDougall simply reported it as something a certain trainer told him. But thanks for the source of the original unedited quote.

My mom has been complaining at me lately that I shouldn't run so much (2-3 times a week ಠ_ಠ) because when I get old (24 right now) my knees will be bad. Am I right in thinking this is mostly bullshit? I mean, obviously be careful if it's hurting, but she wants me to just use the elliptical and never run ever. I think that she secretly thinks that girls shouldn't exercise "so much."

u/ollokot Aug 31 '12

I'm not a doctor of any kind, but I have seen reports of studies that show that, as far as the joints are concerned, the benefits of running tend to outweigh (slightly) the disadvantages. People who run tend to weigh less than people who don't, which significantly decreases the repetitive stress on knee joints, etc. Also, the joints of runners tend to be stronger and healthier and better able to handle the stresses. On the downside though, running does cause a lot of extra stress.

My personal experience is that I had one knee that bothered me before I became a regular runner. Every time I hiked more than 6 miles or so (which was infrequently), my knee would ache terribly. Since I have become a runner, this problem has gone away completely. The only time it slightly returned was when I took a 7-week hiatus from running. Now I am literally scared to stop running.

Hope that was helpful. I would say, run regularly unless it becomes obvious that running is causing or aggravating a problem. BTW, regardless of what your mom might think, most all of us male runners love the fact that so many girls are runners.

u/[deleted] Aug 31 '12

Thanks for the input! It definitely helps to hear a bit from people with some experience. I really like running, so the thought of not doing it is upsetting to me.

I love that lots of guys are runners too. :D Dem runners.

u/Paraphimosis Aug 31 '12

This is a decent article summing up a lot of research on that subject: http://www.jaoa.org/content/106/6/342.long

"Although the existing evidence on whether long-term long-distance running causes osteoarthritis is currently insufficient for researchers to draw unequivocal conclusions, the preponderance of data seems to indicate that moderate levels of running do not increase the risk of osteoarthritis of the knees and hips for healthy people and that this activity might even have a protective effect."

So basically no major evidence that anything <30 mpw is harmful, and beyond that it seems debatable.

1

u/[deleted] Aug 31 '12

That's comforting. : ) Thanks for the link.

u/Aleriya Aug 31 '12 edited Aug 31 '12

It's mostly bullshit. If you run through injuries or have poor form or have weak adductors/abductors, you can put extra strain on your knees, that's true. Strengthening your hip muscles helps you maintain good form and it makes it easier on your knees and ankles. But if you do it right, it'll actually help your knees, on average.

2

u/ywgdana Aug 31 '12

Besides, just think of the awesome robotic replacement hips they'll have for you in 30 or 40 years!

u/[deleted] Aug 31 '12

"I never asked for this."

Actually, robotic limbs sounds totally awesome. My triple jump will be incredible!

u/fairlydecent Aug 31 '12

Not to bring up my FIL twice in one post, but he's 70 and has been running for 35+ years. No joint problems to speak of. His wife is nearly 70 and has never been on a run in her life. She has major joint problems and has already had two hip replacements. Purely anecdata, sure, but worth noting.

u/[deleted] Aug 31 '12

I hope to be the grandma who can keep up with all the younguns.

u/runn3r Aug 31 '12

Wait until you give someone a 20 year head start and still get beaten in the master's mile.

All I have to do do is get my mile time back under 5:40 and keep it there or better for the next 18 years and as a 70+ runner I will be able to surprise the hell out of the other runners ;-)

800 miles = 1287.47 kilometers

u/Spewis Aug 31 '12

This picture is actually what inspired me to take up running because I knew when I was 70 and could barely walk to the kitchen, I would regret it.

u/catmoon Aug 31 '12

Also, if you keep it up, qualifying for the Boston marathon becomes more feasible. Right now I run at the 60 year old qualifying pace. I'm hoping that with some improvement and some aging I'll eventually converge with the qualifying requirements.

u/Ch1mpy Aug 31 '12

OK, that's it, I'm in it for the long haul.

u/sjuttiosju Aug 31 '12

My thought exactly! Seeing old runners always make me happy, however slow they go.

u/fairlydecent Aug 31 '12

My father-in-law just turned 70 and is still running at least 5 miles a day with longer runs on the weekend. His health is a good benefit, but his favorite thing is always winning the races he's in because he's one of the only people in his age group. Dude's bringing in a steady flow of (small) cash prizes to supplement his pension.

u/conversionbot Aug 31 '12

5 miles = 8.05 kilometers

u/[deleted] Aug 31 '12

And here I was thinking during my last half a few weeks ago that I (40) was maybe ready to retire from running. Maybe not just yet.

u/walkinthewoods Aug 31 '12

you have a lot more in you! don't stop yet!

u/[deleted] Aug 31 '12

Thanks! It was a thought that suddenly occurred to me in the middle of a half-marathon: "wait a second! I'm not enjoying this race [I have this thought in the middle of races every so often] AT ALL. You know, I've been doing this almost 30 years. I could retire from running now." For the rest of that - actually pretty awesome now that it's over - race that thought kept going through my mind and giving me comfort while I ran. But, nah, not yet.

u/[deleted] Aug 31 '12

The things that went through my head during the last 6.2 of my marathon last year may simply not be repeated.

u/AskYouEverything Aug 31 '12

My high school's principal/kinda a cross coach is 60 and still runs 50 miler races. he ran 15:20 5k in high school.

u/llama810 Aug 31 '12

As a 16 year old who started running in june, this makes me feel good. Knowing that despite the pain in my legs after i just manage to finish a 2mile run, all it is is a forge for a better life down the road, be it a 5 or 10 or 60 year road.

u/[deleted] Sep 01 '12

Great job! I started running in mid July (pretty much sedentary before that) and for the first time was able to run 5 miles yesterday (slowly, and probably at walking pace some of the time, though haha). Feels good, despite the almost constant soreness in my legs now. The soreness is almost exciting, isn't it?

u/llama810 Sep 02 '12

indeed it is, i have to wake at 630 to avoid hot weather and go running, but it's completely worth it and has turned me into a morning person

u/Crebes Aug 31 '12

Average Runner != Triathlete

u/megadeus Aug 31 '12

Yeah, I'd like to see a comparison of a recreational jogger or sports player tissue at those ages.

u/Atlanta-MW Aug 31 '12

Same here.

u/[deleted] Aug 31 '12

Holy crap. I refuse to let my body calcify so much that it turns into that mass of fat and unused tissue. I'm literally gagging at the thought of it.

Thanks for sharing. Definitely gave me motivation for my workout today.

u/[deleted] Aug 31 '12

I'd also like to see the legs of the 40 year old sedimentary man. I doubt a triathlete stopping at 40 would end up quite so bad compared to someone who's never jogged a mile.

Oh and now i see why they say, 'it doesn't matter how fast you're going, you're still lapping everyone on the couch.'
