有冇師兄食過ZMA補充劑? 主要作用係邊度架? 見唔見效?

Steve03 2009-5-2 06:37 PM

食左會係訓教時修復得快d/叫好d
訓係訓多左, 但有部份人發夢會多左 (即係質素差左),
有人訓醒之後仲好眼訓, 懶床懶長左
所以我都唔知佢有冇用

發夢會多左 =/= 質素差左

actually i read that you only dream during deep sleep.

Also ZMA increases testosterone production up to 30% naturally

yes, wt you mentioned are partly correct,
dreams are happened during deep sleep, there was an experiment that took by the scienctist
they found that the mice without dream for 3 days,
its responded for the emergency was worse when compare with the control data
however, the activity of brain will be increased when you are dreaming..
so...i dont know how to balance it

the increase in the activity of the brain during dreaming is when your brain is saving memories and this includes saving the memory u had in da gym that day (adaptation). This increases yr strength becoz the amount of force yr muscle fibre can generate depends on the ability of your brain control (how much muscle fibre your brain and central nervous system can recruit).

thanks for remain me the concept that making a dream is not equal to bad quality, but i think making a dream is not a necessary process to save memories.

and i'm not sure that you said [i]"This increases yr strength becoz the amount of force yr muscle fibre can generate depends on the ability of your brain control " [/i]



how does the brain control can increase my strength?
in the fixed amount of muscle fibre, the maxium of strength can be increased by brain control?
the strength (or energy) is not come from the muscle fibre?
that's quite interesting~~

would you mind to give me some reference? coz i want to read those information~ thanks~

JGT 2009-5-3 06:28 PM

i havnt got any reference but i think i found it out some some documentary that every human beings are capable of exerting a lot of force that they cant even imagine. theres a story of an old woman who lifted a car and saved a little kid who got trapped underneath it. She can only do that in that moment becoz her brain allows her to do so in that situation. What happens is your brain doesnt wan u to generate that much force at any time u wan becoz u might hurt yrself really easy. muscle fibres and tendons can torn easily. So it makes sense that for strength training u r using a weight so heavy that you can barely handle. This gives stress to yr brain . a signal would be sent to the brain to tell it to allow yr body to get stronger next time. Next time your brain would be able to recruit more muscle fibre after a period of adapation (48 hours)

Think about each muscle fibre as an individual motor. You got the nervous system tagged onto some of them, say 10% and you are only able to generate 10% of yr mazimum force. But by weight training you tag along with more and more motors, say 20%. now you would be able to generate 20% of yr maximum force. strength is all about how much muscle fibre your body can recruit at the same time.

Also another about deep sleep is that a lot of good muscle building hormones like testosterone and human growth hormone are released into yr body. the more these good hormone u got the faster u build up strength and size.

another thing i wan to point out is that there is sumthing called mind and muscle connection. its like when u put yr focus on the muscle you are going to use you can generate more force becoz you are giving a signal to contract yr muscle. for example when u r doing barbell bicep curl you can use 70lb only with both hands together. But if you switch to one armed bicep dumbell curl you can probably move like 40lb on one hand which is more than you can handle with two hands (40 x 2 = 80 > 70) This is becoz u put way more focus on one-armed exercise than two armed exercise.

i hear it before, but i think the "thing" that increased her strength is adrenalin.
gave a signal to increase the adrenalin concentation is the thing that the brain did.

[i]"Think about each muscle fibre as an individual motor. You got the nervous system tagged onto some of them, say 10% and you are only able to generate 10% of yr mazimum force. But by weight training ..."[/i]

[i]"strength is all about how much muscle fibre your body can recruit at the same time."[/i]

so, do you mean the strength is increased by increasing the amount of muscle fibre that the body can recruit at the same time?
the one who can recruit larger force is just because he has the more muscle fibre that the body can recruit, right? but not the mass of muscle fibre?

if this is the fact, the muscle are just recover in that 48 hours, but not grow. it is because we just have to increase the amount of muscle fibre that the body can recruit at the same time, then we reach the goal. but how come the muscle size will become bigger if there are no growth? in your concpet, growth seems useless, i'm quite confuse on that...

anyway, thanks for your detailed explanation~

JGT 2009-5-4 09:44 PM

yes it is true that yr strength depends on how much muscle fibre your brain can recruit at one time.
in those 48hours you do not just recover but also overcompensate which means that your body put on extra size in case your muscle fibre gets torn apart next time providing that you give your body enough energy (calories from food) and materials (protein).

It is possible that one can increase his strength without increasing his muscle size but it is going to be really hard with a calories controlled diet and also the strength increase would be reduced. Thats why for novice trainees we suggest them to start off with strength based program e.g. starting strength by mark rippetoe which gives them both size and strength.
