congratulations for completely refuting your own argument.
you yourself stated correctly that the athletism and hence speed of the runner is developed by muslce injury and subsequent healing-growth of thre injuried muscle.
the reason you gave for it being dissimilar to piano playing is that the amount of depressing/counteracting weight (which causes this injury) is DIFFERENT. not that it exists for one and doesnt for the other, but just that they are DIFFERENT. this is where i wondered if you actually have the mental capacity to even get involved in this argument.
in case you don't understand yourself, the ONLY WAY your argument would work is if pushing down a piano key requires exactly ZERO ounces of weight. If it requires anything more than ZERO, then the comparison with the runner is absolutely valid in every respect.
now, i know of no newtonian force/energy equation that DO NOT FEATURE (counteracting or otherwise) weight as a component. If you disagree with this, you will be saying that lifting 5 tones X cms Y times per second and depressing 2grams X cms Y times per second can be done with any and every set of muscle found on any living organism.
so take your pick, you will either have 8 year olds laughing their heads off, or 2 year olds.
and considering that you agree out-of-the-gate that muscle building IS EXACTLY HOW athletes increase their speed, i hence find the truly innate hilarity in your 'argument' to be the assumption that: just because you cannot build a particular muscle BY playing the piano, you cannot build this particular muscle, period.
but that's almost a footnote compared to the raw idiocy of DA REZT OF YO sheet.
I don't really know what the hell you're talking about
Speed doesn't increase with strenght
If you observe a muscle that become faster you will see no physical changes
What I said is that a muscle before being conditioned must be strong enough to bear weight
If we were just legs then we would not build bigger muscles by running faster because there's no long-term physical change in a muscle that has increase its speed
Our legs muscle grow bigger as we run because there am upper body weight to support
What's so hard to understand?
The most fiber-damaging activity is bearing weight. When muscles can bear a certain weight they're damaged by that weight and grow bigger as the micro-injuries are healed
This is independent from speed
Nothing changes in the muscle after you have become able to move faster
And I repeat it take a look at studies implementing spectroscopy and resonances you would understand this
So how is a muscle conditioned to speed, how come a muscle suddently can move faster?
Because it can released quickler.
Speed requires fast contractions, fast contractions require fast release
Working on conditioning a muscle to release faster means controlling the speed at which contractile receptors get impulses
Only that this is neurological not physical, it has to do with nervous connection and the nervous central system not with muscle fibers. Mind you even on pure physical task like weight lifting there's a huge neurological component and it's the reason why the HST training focuses so much on the nervous central system rather than the muscles
Your argument that your muscles would not grow only is a task would require ZERO amount of weight is retarted
your muscles grow when the stimulus is STRONGE than the current weight bearing potential of the muscle fibers themselves. It's absolutely no true that the only way the muscle can't grow is by having no amount of weight/resistance
THE MUSCLE DOESN'T GROW AS WELL IF THE AMOUNT OF WEIGHT/RESISTANCE IS INFERIOR TO THE WEIGHT BEARING POTENTIAL OF THE MUSCLES
The muscles of a 3 years old has already enough weight bearing potential so that depressing the key of a piano IS NOT A STIMULUS strong enough to cause any micro-injury or any growth
You're the one here with not enough mental capability to get involved in this argument, as clearly any presumptuos, arrogant and plain ignorant person who resorts to insults even before resorting to relaxed explanations and argumentation can only be
