why does stretching feel good?

Postby angelo » Tue Dec 20, 2005 12:42 am

Why does stretching feel good (like when I have just woken up)?
I'm guessing that this optimalizes the muscles in some way, but what exactly is happening? And what might the mechanisms that make it feel good, be? Signals from stretch-receptors?

Maybe speeds up the circulatory system.

Yes it is about the efficiency of the circulatory system, or so i think... Purely as an opinion i would say that they brain interprets the signals from the Golgi corpuscles and neuromuscalr spindles as pleasurable because it "knows" it is good for you. I am not sure, this is purely an opinion

not only that, but your loosening your muscles as well, and loosening muscles make it so you dont feel like you have a gulf ball inside you, I know I had to do it one time or another :wink: , but if someone is too uptight, you could have back problems and for the unrelated part, emotional uptightness can lead to a very low living social life :( yeah, I know you don't like hearing *cough*I mean reading an essay like post :o

All you say is correct but we were discussing the mechanism...

i think it is caused by our lactat acid which is accumulated in some place in our body and those lactat acid, after stretching, can goes to other place to excreted. and also this make our sirculatory system become normal agaon.
maybe it also caused by our nerv which can do better sirculation(i mean function because its circulation system goes on a good condition), then the nerv said huah.. i am alive again.

lactate acid only acumulates when we undergo a frequent tiring activities...but, if we stop doing that (I mean reducing our heart beat rate by taking a rest or anything), lactate acid will be reconverted again and undergo aerobic respiration (because O2 is getting accumulated sufficiently again). So, I don't think that stretching (usually after wake up from sleep) is related with lactate acid because I'm sure that you won't do sports while sleeping will you??

and for the other, I don't think that it's directly related to our nervous system. Just look at the 'stretching' word in the title. From there you can easily guess that it's directly related with tendons and ligaments.

Well let's remember the question: "Why does streching feel good?" There are 2 subquestions to be answered here: "Why does the brain interpret streching as a pleasant sensation?" and "What is streching good for?"
As the second one has nothing to do with the nervous system, the first one has everything to do with the nervous system

As i said, in my opinion the brain interpretsgood things as pleasure. So because it is benefic for the functioning of your body, the brain has "learned" to interpret the impulses that the Golji corpuscles and the neuromusclar fibres give when streching as a good sensation, so that you will do it again. Think of the same situation applied to, hmmm, reproduction ;)
