The reasons we breathe when climbing stairs have nothing to do with the condition

We often think about how without air conditioning we are behind the stairs. Being breathless happens to us all for many reasons. It also happens to those who practice constantly, writes Brighton Side.

Before training begins, we usually make heat. This is important because it contributes to muscle heating, increases the flow of blood and oxygen, and reduces the risk of injury.

And when you start climbing stairs, you quickly go from rest to being much more physically active, without getting warmed up.

That's why your body will have to work harder to have more oxygen in your muscles in a very short period of time, and your heartbeat will grow.

So it is natural to feel tired afterward.

Climbing uses another energy system than normal cardio exercise. It's called phosphagean energy. It is used when your muscles need much energy during short - term but intense activities.

There are some molecules that need this system to work, but there are not many of them. So it is normal to remain breathless after a very short period of intense activity than after a longer, more stable card session.

You've got two kinds of muscle fibers with a slow shake and a fast shake. If you are an experienced runner, you can endure the long - distance run, thanks to slow fibers that are easier to tire of, but they do not have much power and strength. When you walk down the stairs, you need muscles that quickly shake for those quick, explosive movements, but they tire faster.

A person who does not exercise too much can become as full of breath as a person who practices regularly when climbing stairs.

If you have trained your physical resistance by running, you have used more of your slow fibers and they rely on aerobic metabolism. However, when you climb stairs, those brief bursts of activity require anaerobic metabolism. This produces carbon dioxide and hydrogen, for which resistance athletes are more sensitive than other people.

That is why it may be easier for a person who does not exercise much to climb a ladder than for someone who does training to increase resistance.
