How Do You Try Out For Mls Soccer



In recent articles in this blog, I talked a lot about hair and quite a few people among you begin to wonder how the bike could be beneficial hair ... ;-)

Well, let me clarify that when I speak of the famous hair, I am referring small blood vessels that surround our muscles and used to deliver oxygen and nutrients they need to operate

... Now we know that bats will not grow his hair cycling with you ;-) wonder how the fact of driving calmly (as I do this last time) may develop blood vessels and, moreover, how it can benefit your performance that ultimately is the goal.

Okay, so below, a short course in anatomy book excerpt from "Planning Pedaladas silent" written by Chema Arguedas (as a bicycle tour that took us specializing in these areas).

cells of the human body, including those leg muscles need oxygen to burn food and produce the energy necessary for pedaling. More effort is important, they need more oxygen and nutrients. These are supplied by the blood through blood vessels, therefore, we understand very quickly that more ships were in the muscle, more fuel it will burn more quickly and / or stronger can be run.

So how can they come?

When you drive slowly (between 50% and 75% of our frequency max heart) the heart begins to beat faster to increase blood flow to the legs and happens to meet this need for extra energy. As a result, blood typing and lack of space in the walls of the capillary network, which is itself elastic, elongated and branched gradually to more easily (and faster) all the muscle cells. Over time our muscle eventually be surrounded by blood vessels like ivy around some houses, so the heart has less need to increase the pulse for the food.

Now, what happens when it exceeds 75% of our frequency heart?

course, as you noted yourself, your legs still work but for that, not enough oxygen. It needs a more powerful fuel: lactate.

As you can imagine, lactate is very powerful but at the same time, very contaminant. Between 75% and 85% of your maximum (below the anaerobic threshold) blood happens to the legs can pick it up without problem, but once you cross that threshold, it begins to accumulate because there is not enough volume of blood for every scan and, if the intensity increases, there comes a time that the muscle is completely saturated ... you have the legs that burn (it tells you something ;-)

So, again, we understand very well the point of having a well developed network of blood vessels around the muscle, there will be more blood to sweep this shit to burn lactate and legs come much later, may be later than others ...

;-) And that's not all, lactate also has another very interesting property. Indeed, it has the ability to make highly permeable capillary walls. In this way, the red blood cells can cross them to reach more quickly cells that, at this moment, are in high demand. But ... if the blood through them, it means they do not push the walls and therefore do not develop hair

... (Pause for thought ... ;-)

Just in case you do not have any understood: If you drive over 75% of your max before they developed the ability to properly oxygenate your muscles, you will progress forever, because you will always arrive at saturation (burn leg) very quickly because of a tissue capillary underdeveloped.

The ancients had reason in the beginning of season should run cool, now you know why ... ;-) Good
