Thanks  to Ruuds   question on comparison of performance  or  for use  of  physiological reactions  whine training  load  or targets specific.
 Here a nice review over a 6 month training idea.  Below I s  an initial  workout  we often use  to " Calibrate"  daily trends  and reactions. It is easy to see, that we sued  10 min load length  and we always use the same step s  and loads same trainer  same  day time.  So  first 10 min load  one  than increase by a fixed   value  and so on.
The original 5/1/5  indicated a  most likely  stroke volume limitation.
As mentioned before   thB  can give some indication of the fight between vasodilatation  due to CO increase  and  vasocompression  due to  muscle contraction.

Now in this case  we had  as well physioflow  so that's  why we were confident  it  was a  SV  limitation.

Now  in short some hints  for all  users   of MOXY  who do not have a PHysio flow.
1. Look at tHb trend. 1 min calibration  at rest  and than look  at  the end of the   workout.
 as well the trend  during the load increase every 10 min. ????

Who wins  and  why are  we confident , that the capillarsiation is not that bad ?

Now  look  metabolic  trend  so we  use SmO2.
Where would  you  place a  relative balance metabolic  intensity  and   for cyclists  or runner  FTP  or  optimal  running intensity ? easy to  find  O2  delivery  surplus  and O2  delivery  deficit. I hate the work  deficit  give me a better  one. )  What is the compensator in the   higher O2  utilization than delivery intensity. Last visual  question. By  what time do you see  a biased  O2Hb  and HHb  crossing over  so   deliver limitation  starts.???

 Now  the target  training was a  stroke  volume training  as many times  per week  as  we where able to actually stimulate  SV.
On days  where we had negative  feedback in the warm up  10 min steps  so  still not recovered  cardiac systems  or  not enough recovered plasma  volume  to target  SV  stimulation we did  ofen a  short  but specific left or right ventricular stimulation.

Now  3 month later
 same 10 min  loads. hint look at tHb  and look  at metabolic  demand SmO2  but look the compensator change.

Now  the full pictures  shows  a  SV  workout  after the  " calibration  s 40 min  which showed on these day a positive situation  with a high chance  to get a  great SV  stimulation. Ass you can see e nice  tHB   increase by a relative  low  HR the load  was the same load as  10 - 20 min on these day. The load    can vary  so some days  we had  0 - 10 min load  and some days  we  had  20 - 30 min load .  If  we   used  30 - 40 min load  we only  where able to do this in short interval loads  of 1 - 3 min maximal duration's. Remember this is NOT  a COOK BOOK . This is a  daily  review  on the physiological reactions  from the  day  or days  before  and we use  wattage  to  get the feedback on performance  change   so we use  the same physiological stimuli  but   not always  by the same physical performance Level. So FTP  intensity or  in  another words, metabolic balance, is based on  SmO2  and tHb  and HR  trend ( we use  as well RF  and CO2  trend  with a  capno meter)   and never on the FTP  wattage  we may  have found somewhere a  few  days or weeks  ago in a test. This  does NOT  mean FTP  does not  work. In fact FTP based on A. Coggans  idea is most likely the smartest  way  and cheapest way to get a  physiological sound  idea on a metabolic  balanced  situation. What NIRS is doing, it  just may confirm this  fact  but as well confirms the fact  that  we not   are able to be physiologically  sound   all days the same way  and therefor  FTP  levels  in wattage  will fluctuate as every body knows and feels  but simply may not accept.. So  use FTP  and   MOXY  and you are a far step  forward in understanding intensity zoning and so on. 
No  let's  end the idea.  3 month later. Why three month . No idea  just old  classical habits. No physiological reason  and in fact a  not great idea  to use  periodization this  way as we learned  much better is that the  physiological changes  dictate the periodization idea or better the time, when   we  can change a stimulus  because we adapted  and or  we may keep the same idea going  because it is  still an effective  stimulation.
  Adaptation as the contradiction it is.
You make progress because your body is  able  to adapt. Because you adapted  you  do not make  anymore progress.

Most likely this   contradiction is the most single reason  why many  top athletes  do not progress anymore. It is relative easy  to  move up to the top  as you try out  always new  and interesting concepts.
 Now suddenly you win  and you are up there  and than   we start to look back instead of  w  forward  and look what I  have done in the past to get up  where I am now. Meaning I go back and  copy or   repeat  certain workouts  which where great  and   successful in that stage  , This great workout  created an adaptation in structural  and functional  directions and because we adapted the same stimuli are not  any more  as efficient or effective in stimulating  new   better   structural  and functional  responses and  may,  if  I am lucky, stay  for a while on that reached performance level or I may in fact  loos  performance.
Using %  of a maximal  found   critical level  is  the most common reason  why  stimulation do  work at the start  but  not  anymore down the road.
 80 % of  VO2  max  can change  on  what  may be stimulated.. This  holds  true  for  any  calculated  zoning idea as it does not take in  account the physiological  changes  which  may or may not occurs.

That's why  using a  bio feedback  like NIRS  signals  is  so exciting for us as we see now that  for example by  75 +-  %  of  VO2  max   we had  originally a  drop in tHb  as a sign of  a win  for the compression against the a vasodilatation of CO  and therefrom we created a delivery limitation. Now  some weeks later  we see that tHb  is increasing by the same  %  VO2  or  same %  FTP  or  what ever  and we  now  see that we may have  new  a utilization limitation which got  created  due to the elimination of the delivery limitation.

So last   graph in this case idea of  elimination  for the moment  SV  or delivery limitation.

You analyze  and you give the  answer  for yourself  or on here.
Welcome  in the kitchen of  chefs
Now  below is thee lates   workout  and look what ha s changed  a few  month later.
10 min  to level 4 leg  3 march plus  co2.jpg

What  changed  additional ? And the  after  calibration  section is a specific  utilization  stimulation using load  10 - 20 min  to avoid  an overload  of the current limiter.
