CNS fatigue and "central governor" model....

[system]

Its only been a year, I’m interested myself

According to Central Governor Model (Noakes et al), fatigue is relative emotional representation of effort that system (CNS-central governor) makes to maintain homoeostatics (homeostasis), thus preventing “catastrophe” leading to injury and maybe death!
This doesnt mean that there is no negative influence of “poisoning” metabolites on muscle contraction, neural conduction etc, but this model suggest that their influence is controled by shuting down the system before their concentration reaches critical limit - “catastrophe” running out of homoeostasis!
The key evidence for this is that neural activation of muscles during fatigue is not maximal (as other “catastrophe” model propose, like cardiovascular/anaerobic model) but less than maximal, even come to 30%…
So the key question is:
Is CNS fatigue an inability of Neural Drive (CNS) to fire impulses or he is not willing to do it (to maintain homoeostasis, and system functioning)?
After sprinting there is lower CP concentration (not ATP) in muscle cells and lower PH of cells, so this maybe induce Neural Drive inhibition, wich we see as CNS fatigue! According to literature, to return Ph to normal is needed for about 20-30min, so this is the key proof for Charlies long rest between sets and reps…

I went back to reading Noakes’ Central Governor theory and I could not do without noticing how the brain (CNS)- heart (ANS) connection is emphasized,which brings us back to Charlie’s Hi/Low approach,and the never enough highlighted importance to have and mantain a well structured general fitness in place even for the power speed athlete…

CFTS :where it all begun…

Charlie’s words make the whole point (no surprise…): I might only add I just had the chance to see the most recent developments of the technology features and they most interestingly correlate CNS potential assessment with precise indications about adequate momentary training prescription.I am now extremely curious to explore how numbers and waves of stimulation fit different individual athletes.

Waves are the perfect way to view the whole picture from the overall forward planning perspective in the long and medium term, and now, reactively and preventatively, from the observed and predicted (OW) status.
This can be a fascinating exercise as you can lay out the overlapping waves working backwards from the peak in general terms. Pakewi, think of the graph representing the time frame for optimization of individual training componants in wave form and lay each componant wave out in an overlapping fashion backwards from the point where peaking is to be initiated. Then you should be able to start filling in the numbers as a planning aid. We can go over this more specifically when you’re able to get over here again.

Fascinating as an adventure in the outer space…Truly looking forward to,Charlie!

Funny you should bring that up! Many of my teachers suggested I was spending a lot of time there during classes.

I have used Excel to plan out my year and the waves just like Charlie is explaining. This gives me the ratios between each training component in the Vertical integration model i need to achieve and then i can work backwards turning these ratios into sessions.

I guess with OW it would be even better because you could see it in real time. I’m saving up… but it will be a while.

Waves? Which waves are you talking about?

I just finished working one seminar work, subject was training: planning and programming. Based on my conversation with Juggler, tc0710 and blexy (http://www.charliefrancis.com/community/showthread.php?t=11026) I come to an “concept” about planning and programming the training:

1. Plan should have one stiff component to allow athlete do adapt to plan (planing recovery, periods in advance, wave-like loading) to acheave top-forme at the most important time and to avoid injuries.

2. Plan, on the other hand, should also have pliable component, to allow itself to adapt to athletes and changes in the training eniroment.

Changes in athlete is based on his rhytmic cycles in his working capacity, biorhytms, C.A.R., pschological states, fatigue etc. So is this waves you are talking about rhytmic cycles in his working capacity, biorhytms etc or something else?

Pakewi, can you please expand on how does HI/LO approach fits in the Central Governor Model (or vice versa). I am sorry, I dont get the concept right now…
