Re: What happens when you sit at a desk for 13 years and also exercise

Recently, there was an article in New Scientist about this[1]. Basically, if you sit for more than 6 hours a day, one hour of exercise a day doesn't undo the damage.

The solution is to get up and move around often, i.e. every ~20 minutes or so.

Exercise is still good even if you stand/move around often. And standing all day also has its problems, like others have mentioned.

"Sitting at desk considered harmful considered harmful"? To be fair, I haven't seen any standing desk articles claiming that standing is some sort of magical panacea that can fully substitute for conventional exercise and a healthy diet, although I'm sure there's at least one out there.

"Sitting is bad for you" is one of the hottest topics in popular health right now.

Standing isn't so much a panacea as an alternative to the aforementioned sitting.

Our forefathers didn't formally "exercise" in a gym - they moved around. As a practical matter, standing allows desk workers more movement than sitting does.

The problem is that there is no evidence that suggest standing in front of a computer screen helps at all in those situations as well. You're still stationary. You aren't moving. Moving your feet around below you to adjust the weight on your legs does nothing for your cardiovascular system. Unfortunately, as people who are tied to their computer screens for most of the day, we have very few options. One is to exercis…

there is no evidence that suggests standing in front of a computer screen helps From the last of the three links I posted: "They found that standing up engages muscles and promotes the distribution of lipase, which prompts the body to process fat and cholesterol, independent of the amount of time spent exercising. They also found that standing up uses blood glucose and may discourage the development of diabetes."

I apologize, I skimmed through that article too quickly.

Nevertheless, I will still hold my position that I was once "Fat", with high cholesterol and could barely hold my own body up. With what I have stated in my post, I am now healthy and can do things that most 20 year olds can not do. So, I guess it works for me pretty well.

One case = anecdote. There is actually some evidence that you can't counteract the effects of sitting with exercise, unless you exercise more than you sit. And what exactly does "I'm healthy" mean? Is that what the doctor says after doing some test or is it just how you feel? What would be the status of your health (as measured by tests from a doctor) if you had an active job and some moderate exercise for the same p…

I had a physical by my doctor about 3 months ago, as stated in my writing. So, yes... "I'm healthy" was declared by tests from a doctor.

Then it's seems that it's working out for you and maybe that would be a "middle road" for us, desk-bound people. However we still cannot fully counteract the negative effects of sitting, to quote the article which I linked in my previous post:

"Adding to the mounting evidence, Hamilton recently discovered that a key gene (called lipid phosphate phosphatase-1 or LPP1) that helps prevent blood clotting and inflammation to keep your cardiovascular system healthy is significantly suppressed when you sit for a few hours. "The shocker was that LPP1 was not impacted by exercise if the muscles were inactive most of the day," Hamilton says. "Pretty scary to say that LPP1 is sensitive to sitting but resistant to exercise."

Right, it isn't just that exercise is good for you but rather all the time spent not exercising is bad for you.

Every time one of these articles comes up, the author posts blood tests, 'health screening results', and bizarre plots from sleep EEG machines. These are all worse than useless.

Because there is only one sample. You have no way of disentangling the effect of the condition being tested, from the effect of everything else. You'd need like a hundred people for that. There are never 100 people.

For the past month, I've added shoulder stands to my workout, and also been feeling really energetic. It would appear they are amazing. That, or it's due to the weather being sunnier, and being on a nice project at work. I bet a blood test would show my cortizol levels are lower, which would give this headstand thing the appearance of science.

These N=1, test my blood, wear a skin salinity tracker for no reason experiments are playing at science, rather than achieving science. Like paintball is expensive but still doesn't kill people.

If this guy wants to write about his subjective experience of doing situps while doing sitdowns, it's not any less scientific for lack of a blood test.

You could say that standing while working could have positive effects, but it's not the complete solution for good health.
