question on daily jogging

Jimmy zhang said:

Does that mean if I had a single longer run I should be able to stop
for a day without feeling lethargic??
Also how much water do I need?

I am a starter on jogging, so I have been jogging 2.5km everyday,

I really like the refreshing feeling after jogging, however, if I stopped
just
for a day, I will feel lethargic.
Is this normal? Or, is my body trying to tell me something?

yep. normal. make one run longer. you'll feel
it the next day.

no. i'm not saying that. i was trying to say that making
one day a longer run will stress your body a bit and
you'll feel it the next day. almost right away, you'll
improve. then the 2.5 Km runs will feel easier.
these beginning great feelings will only get better.
keep it up. as for water, at these distances,
don't worry too much about it. it won't matter.
you might begin to think about how much you are drinking
though the day and if it's enough. the standard ideas.
clear pee is a good place to start.

As to the refreshing feel after jogging, is that because the heart
is pumping more blood and oxigen into organs so they function better??

.... while i wish you would bottom-post following the conventions
of usenet and, in particular, the posters on this newsgroup,
i don't want to make a BIG issue of it.

but, as to why we feel good, beats me. i believe it is NOT
due to endorphins crossing the blood-brain barrier as the
pop press would have you believe. but, i can tell you,
in private now that you have joined the running fraternity,
it only gets better.

Endorphines don't need to cross the blood-brain barrier - they are
released through the pituitary gland which has direct access to the
blood stream. The pituitary is one of the few sites of the brain that
are not protected by the blood-brain barrier, as it is a major site of
hormone production and these need easy access to the circulation.

As to why endorphines make you feel good, neither why exercise makes you
produce them nor how they give you that euphoric feeling of well-being
is precisely known. One theory is that they stimulate the release of
dopamine, which is the hormone closes associated with the 'pleasure
centre' of the brain.

Besides endorphines, a general improvement of circulation will pump more
blood to the brain, probably heightening your awareness and making you
feel better.

Sorry, I think you're wrong. I've read several articles in the past 18
months that made it clear that scientists have never understood the
endorphin "runner's high" thing, but they're onto something else which
is chemically similar to THC (from marijuana) which could be the cause
of runner's high.

I'm 90% sure one of the articles was in Runner's World, but I don't save
my back issues so I can't find it for you.

we are a series of chemical reactions. how can consciousness arise from
something made of chemicals???? how can chemicals feel?

keep it in church, God-boy.

Equally puzzling: how can chemicals arise from something made of
conciousness?

Why do you say I'm wrong? The paragraph you have quoted contains basal
neuroanatomy and -physiology concerning the function of the pituitary.
This is well explored and undisputed knowledge.

If you were referring to the endorphine-dopamine connection - it's a
theory, and I was referring it as such. I wasn't claiming to know the
exact truth. You are of course free to question existing theories if you
have further knowledge of the subject.

Concerning the postulated THC-like substance the researchers are onto,
it sure sounds interesting, but it doesn't neccesarily make the
endorphine-dopamine axis theory wrong.

i know the answer. If you understand how the universe can arise from
nothing, you can understand consciouness. The answer just came to me.

Just because blood doesn't cross the barrier doesn't mean that
molecules below a certain threshold size don't. Radiotracer labelled
drugs can be mapped in the brain by PET scans.

True. Your point being?
