This week, I’ve ended all my classes with a bit of a discussion re: the cooldown process and the terms under which to cool down.
Suffice it to say that an “official” cool-down period has been a necessary inclusion in most classes, because of the potential risks that blood pooling may have on both high-end athletes and those with heart conditions. It’s interesting to note that high-end athletes require this more than your average exercise enthusiast. It makes a lot of sense when you think about it. Well-trained cardio athletes have heart rates that slow down very quickly, and with the large veins in our legs, sudden stopping can cause blood pooling in the lower body, hence causing dizziness that could lead to fainting.
This can happen with your average person as well, so the take home message really is to ensure that one doesn’t just completely stop and stand still after intense movement. Truthfully, most people will walk the effort off, although from personal experience, I do know of some who will just stand or sit in one place and breathe, then feel light-headed and woozy. It’s for these types that this take-home message needs to be most loud and clear.
The article brings up a very important point re: lactic acid build-up. To this day, many fitness professionals still use that as the reason for soreness, which has long been established to be false.
In addition, the concept that a gradual cool-down helps to flush out lactic acid in the muscles, allowing for a decrease in soreness the next day, has been long-established as false. It’s probably worth reading more into this, if you personally still think that lactic acid has anything at all to do with muscle soreness.
I’ll keep reading these articles and sharing them as long as you keep asking about these topics! Have a great week!
