“We never dreamed that this muscle has this type of capacity. It's been inside our bodies all along, but no one ever investigated how to use it to optimize our health, until now,” said Hamilton. “When activated correctly, the soleus muscle can raise local oxidative metabolism to high levels for hours, not just minutes, and does so by using a different fuel mixture.” I'm can't evaluate the claims, but this kind of lan…

I wonder if there is some kind of unintended consequences to using that fuel mixture...

No, we're designed to do it in all of our skeletal muscle

Hmm, weird. I've gained roughly 50 lbs over the course of the pandemic. I've been working from home and often work from the couch, bed, or the dining table. I originally attributed my weight gain to the lack of commute, and I'm sure that's part of it. But when I sit at a proper work desk I do something similar to "soleus pushups" as part of my thinking process. Maybe I should start doing these again.

In this case, is the body releasing actual fat into the bloodstream for use by the muscles, rather than the fat stores burning fat directly for ATP?

Yes, fatty acids are bound up in TriAcylGlycerol (TAG). Exercise triggers the breakdown of TAG in fat reserves, sending fatty acids into the blood. These fatty acids go through a pretty complicated process to be delivered into a muscle cell, and then into the muscle cell mitochondria. This transport process cannot keep up with energy expenditure during intense exercise, thus the cutover to stored muscle glycogen (and…

What is meant by intense exercise? For example, vigorous cardio (age dependent but about hr 150 bpm) is one familiar benchmark, but is this considered intense exercise?

There are a lot of callouts of "This is BS" in regards to this article. Look at it from a different perspective. I would HIGHLY prefer this to a short press release blurb that allows pop-science clickbait aggregators (or even worse, the "science" sections of CBS/CNN and the like) to have first crack at it. This was produced by the university themselves, and provides a concise yet accurate and detailed overview of the…

Exactly. Essentially the trick is not "use this muscle". It rather is "do this specific movement with this muscle. I can describe it quite simply, but to truly learn it you'll need a biofeedback device and you need to know what you're working towards." There are a lot of surprising skills that we could learn if we just knew how and put in the effort. See e.g. the blind mountainbikers using echolocation to 'see' the p…

Related, back in the 80's I tried a friend's small biofeedback device and learned in a short time how to really relax.

The device was a galvanic skin response device that looked like a mouse.

You put your fingers on it and it would make a tone that would decrease in pitch with less muscle tension. I laid down and tried to decrease the tone and I gradually learned where I was holding tension and how to relax. As the tone got deeper I would get closer and closer to falling asleep.

Ironically, I'm a sedentary person who doesn't have enough energy to do 10 stations at the gym. If I do back & legs I'm pretty much done for the day.

While I was reading the article, I realized that my need for optimizing for efficient blood sugar use is different than the many who would rather waste it.

wonder if drummers (who may activate it more than others) have statistically significant advantage over others with similar sitting down lifestyle and energy output... big claims, great if true!

I'm a runner who's fairly familiar with the difference in sensation between activating the soleus and activating the gastrocnemius (thanks PT). I'm also a drummer and I'm pretty sure most of my pedal-work while drumming is gastrocnemius-centric.

I think the soleus helps to pump blood. Flexing the soleus could be improving circulation, which is responsible for some of the allegedly observed effects. In Japanese there is a saying "ふくらはぎは第二の心臓" (fukurahagi wa, dai-ni no shinzou: the calves are a second heart). Calf-io-vascular workout? Haha.

A great pun, but the laughing at your own joke is the best!

If you do back and legs you should be done for the day. Split your posterior chain. :)

First, they get the university to publish an article making their claim seem credible. They then get an investor to give them $300,000 and make a custom order with a factory in China to add another piece of plastic and some branding to an existing device. They wait 3 months and then receive 30,000 "magic" gizmos in the mail. Then, they sell people a $250 electric muscle stimulator that you wear while sitting. Then th…

You spent all this time writing a comment calling out this study as a fraud appealing to lazy people, but it seems you were too lazy to read the article and truly understand the device's role...

I read it. Looks like a bunch of BS.
