They find that you have a lever that increases your desire to exercise.

It is true that when we train regularly, there comes a point when the body asks for more. But of course, the hardest part is to start. The ideal would be a switch that generates these desire to play sports What do we need to start forming a habit? And what if it turns out that this switch actually exists?

This may seem like something out of a chapter Black mirror. Of course, if you imagine this as a real switch, it would be from the realm of science fiction. However, a group of scientists from National Cancer Research Centerin Spain, just found a way to make our muscles they ask into our brain, which increases our desire to exercise.

These are three proteins that feed on each other. They are generated by the muscle when it into full activity and they act on the brain more or less continuously until, having reached a point where physical activity can be harmful, they are regulated to reduce its level. Thus, our desire to play sports They increase, but only enough to keep our physical activity at a healthy level. These are all benefits. Wouldn’t it be great to be able to flip that switch whenever we want?

Three proteins that manipulate our brains

These scientists analyzed the activation of certain proteins in muscles during physical activity in both laboratory animals and human volunteers.

They found that when muscles contract repeatedly, two proteins called p38α and p38γ. In turn, the second promotes the activation of another protein called Il-15which acts on the motor cortex of the brain, which is responsible for movement. All this together increases the desire to exercise, causing more of these proteins to be activated until it reaches a certain limit.

This conclusion was reached not only by knowing The role of IL-15 in the brainIn both animals and humans, it was observed that the activation levels of these proteins were higher in people who exercised more.

What’s the point of knowing? switch desire to play sports?

Knowing the switch for wanting to exercise can have many functions. On the one hand, it can serve as a guide personalized exercises each person, checking which sports activate the greatest amount of these three proteins.

Also, although it’s a bit more complicated, it would be ideal find a way to activate them without the need for prior muscle contraction. That is, stimulating the desire to exercise starts from scratch.

The study noted that although they have basic lower levels, Exercise also causes these proteins to be activated in obese people, so it would be very useful to flip the switch to help them exercise.

More research will be needed to achieve these results, but something very important has already been discovered. It is true that our muscles require more. Until we can activate it from the outside, if we want to increase our desire to exercise, we must try to overcome laziness. Once we start, everything will be easier.
