Discovery: 'Special' muscle can boost glucose and fat burning, boosting metabolism for hours while sitting

From the same mind whose research inspired the notion that “too much sitting is not the same as exercising too little,” comes an important discovery on his ear to replace a sedentary lifestyle: the soleus muscle in the calf, although only 1% of your body weight can do great things to improve metabolic health in the rest of your body if activated properly.

And Mark Hamilton, a professor of health and human performance at the University of Houston, has explored just such an approach to optimal activation—he pioneered the “solus pushup” (SPU) that effectively boosts muscle metabolism for hours. Even if someone is sitting. soleus, one of the 600 muscles Human bodyThere is a posterior leg muscle that runs from just below the knee to the heel.

published in the journal iScience, Hamilton’s research shows the ability of the sole pushup to improve blood sugar regulation by maintaining an elevated oxidative metabolism as a solution to any of the currently touted methods, including exercise, weight loss, and intermittent fasting. more effective than Oxidative metabolism is the process by which oxygen is used to burn metabolites such as blood glucose or fat, but it depends on the immediate energy needs of muscles while working.

Hamilton said, “We never dreamed that this muscle had this kind of ability. It’s always been inside our bodies, but until now no one has investigated how it can be used for our health.” How to Customize. “When activated correctly, the soleus muscle can increase local oxidative metabolism to high levels for hours, not just minutes, and does so by using a different fuel mixture.”

Muscle biopsy showed that the only refueling was the least glycogen contribution. Instead of breaking down glycogen, the sole can use other types of fuel such as blood glucose and fat. Glycogen is normally the major type of carbohydrate that fuels muscle exercise.

“The sole’s lower-than-normal reliance on glycogen helps it to function smoothly for hours without fatigue during this type of muscle activity, as there is a certain limit to muscle endurance due to a lack of glycogen,” he said. They said. “As far as we know, this is the first concerted effort to develop a specific type of contractile activity focused to optimize human metabolic processes.”

When SPU was tested, whole-body effects on blood chemistry included a 52% improvement in excursions blood glucose (sugars) and glucose drinks require 60% less insulin within three hours of drinking.

The new approach to keeping the sole muscle metabolism humming is also effective in reducing blood fat levels (VLDL triglyceride), doubling the normal rate of fat metabolism during the fasting period between meals.






single pushup

Based on years of research, Hamilton and his colleagues developed the soleus pushup, which activates the soleus muscle differently than standing or walking. The SPU targets the soleus to increase oxygen consumption—much more than is possible with these other types of sole activities, while also being resistant to fatigue.

So, how do you do a sole pushup?

In short, with feet flat on the floor and muscles relaxed, the heel rises while the front of the foot remains in place. When the heel reaches the top of its range of motion, the foot is passively released to come back down. Its purpose is to simultaneously shorten the calf muscles while the soleus is activated naturally by its motor neurons.

While the SPU movement may sound like walking (although it is done while sitting) according to the researchers, it is quite the opposite. When walking, the body is designed to minimize the amount of energy used, because of how the sole moves. Hamilton’s method reverses this and forces Solus to use as much energy as possible for a longer period of time.

Hamilton said, “The sole pushup looks simple from the outside, but sometimes what we see with our naked eyes isn’t the whole story. It’s a very specific movement that’s right now designed for wearables to optimize health benefits.” It requires technology and experience.”

Additional publications focused on how to instruct people to learn this singular movement properly, but without the sophisticated laboratory equipment used in this latest study.

The researchers were quick to point out that this isn’t a new fitness tip or diet of the month. It is a powerful physical activity that takes advantage of the unique characteristics of solius.

Potential first step towards health care success

Hamilton called it the “most important study” completed in his Metabolic Innovation Lab at UH and said the discovery could lead to a solution to a variety of health problems that result from spending hours each day. muscle Metabolism that is too low is caused by inactivity. The average American sits for about 10 hours a day.

Regardless of a person’s level of physical activity, too much sitting increases the risk of heart disease, diabetes, dementia, and more. More than half of all American adults and 80% of those over the age of 65 are living with metabolic problems caused by diabetes or prediabetes.

Having a low metabolic rate while sitting is particularly troublesome for people who are at high risk for age-related metabolic diseases such as metabolic syndrome and type 2 diabetes.

Hamilton noted that inactive muscles require less energy than most people, adding that it is “one of the most fundamental, yet overlooked issues” to help prevent certain age-related chronic diseases. Metabolism guides you towards finding solutions.

“All 600 muscles combined contribute to only 15% of the oxidative metabolism of the whole body in the three hours following carbohydrate intake. Despite the fact that the sole is only 1% body weightThis SPU is capable of readily doubling its metabolic rate during contraction, sometimes even tripling, leading to whole-body carbohydrate oxidation.

We are unaware of any existing or promising pharmaceuticals that come close to increasing and maintaining whole-body oxidative metabolism in this magnitude.”
