Anyone know the science of why we get a "second wind"?
H.I.M. is believed to be able to generate a second wind a second time. check out the thread entitled " H.I.M. as good as a five mile run?" very interesting read with alot of research backing its theories.
could be attributed to a last rush of adrenaline or stored carbs, but I can only speculate.
From what I've read (limited research at best), the "second wind" is an adaptation phase by your body. Basically you have to cope with your inability to use muscle glycogen as a fuel after a certain point. You've used up a certain type of fuel and you get tired. Then your body adapts and utilizes other components to energize you. Your heart may decide to step it up a bit, for example. So now there's an increase of blood flow to the muscle compensating for a decrease in muscle glycogen. In addition, serotonins and other pleasure / pain killing chemicals release as your body experiences hardship. Et cetra, et cetra.
The general idea is that your body is an adaption machine, and as it uses up one source of energy, it will find another (after a slight pause). = Second Wind.
Thank you bubble boy, that makes alot of sence and some of that is what i was thinking.
mmm, so i guess thats why fat/carbs is a "long term" energy source and why u have to do cardio for a certain time frame or method to burn fat? (if that makes any sense)
Sorry, cannot help, as I have often wondered this myself, and certainly felt the effects fo this in action. What Bubble Boy mentions seems to make sense to me. It is certainly some form of adaptation.
