The hockey analogy doesn't exactly compare to strength/endurance sports. In competitive sports with an opponent, you conserve your energy until you need to use it.

if comparing hockey to lifting weights, the dude would be more like a furniture mover than an OL. the furniture mover doesn't try to max out his ability to move weights on every go. he plans out which things to move when, and mentally takes note of times like going down stairs and such when it's gonna take more effort.

in hockey you sprint when you need to and set up position when that's needed.

I will say this, I found the part in that original article about serotonin influencing the intensity of muscle contraction very interesting. I may be experimenting with this in the future.

Chad, the CNS is like the boogeyman. Stop believing in it, and it will stop bothering you. Just saying the letters CNS will take 2% off your total.

What's wrong with this?

Yeah, I'm not too sure about that part of the science since I've never seen that before.

Generally, in motor learning and muscle contraction is an all or none phenomena and neural strength is regulated by increasing recruitment, rate coding (frequency), synchronous contraction, and a couple of other factors.

I never seen anything that suggested serotonin in the in the brain is involved with increased intensity of muscular contraction. Even googling this there is nothing on it.

I looked at the abstracts that were posted and most of it is on peripheral serotonin, and most of them were on blood vessel effects, and I tihnk one was on attentuation of tension so..... I'm not exactly sure where he's getting the serotonin chemistry from. It seems bunk unless better resources are posted.

I'm not one to ever believe that we'll fully understand neurochemistry.

I don't want to go read the original article again, but I didn't notice where he was talking about brain serotonin, I was under the impression he was talking about peripheral serotonin...so that first link he posted http://www.ncbi.nlm.nih.gov/pmc/arti...492609/?page=1 seems to bear this out.

Yeah, I read that one.

The funny thign is that there's no significant research on that from that point (1970s) on which I find hard to believe if it was really that important.

Plus the fact that they were injecting 5mg/kg of serotonin into the animals makes me think that it probably doesn't occur that way in the human body

It does seem to influence the presynaptic release of acetylcholine, but even then those nerve transmissions to alpha motor neurons are still all or nothing. Varying the intensity of a-motor doesn't increase strength; you have to increase firing rate of a-motors (or amount of a-motors) to get increases in neural aspects of strength


edit: just auth'd you John Broz so hopefully you can clear up some of the stuff for us? (if that's actually him).

Broz didn't write that stuff. A guy named Brent did.

A quick search of PubMed would seem to show that serotonin and the NMJ is still being studied...Temperature dependent modulation of lobster neuromuscular properties by serotonin and Characterization of prejunctional serotonin receptors modulating [3H]acetylcholine release in the human detrusor, among others.

SSRIs actually attenuate performance in this study

http://www.ncbi.nlm.nih.gov/pubmed/11441370

This one too:
http://www.ncbi.nlm.nih.gov/pubmed/10919962

If anything I think exercise would downregulate serotonin receptors in an attempt to decrease fatigue for the adaptation that we're looking for

I haven't seen any compelling evidence that shows serotonin is important peripherally though...

Speculation at best. If it fits with his experience, then cool.

Cillis: From what you've said previously here, and what I've seen you post on Facebook, you are fond of ignoring the advice on topics that you specifically ask people about, wasting everybody's time and effort.

I see John Broz joined up. Maybe he can comment on this stuff. He seems to be fond of googling his name and seeing what folks are saying about him and his athletes.
