It is fun to watch  some  high budget sports  and some of the comments  from the Pro's. I will start to  show you some very practical situations over the summer and the regular reader will see how far apart  our ideas are from some common traditional ideas.
  Here a start.
 Tour de Romandie in Switzerland.
 2 interesting riders.
  . 1. Nibali
"Nibali frustrated with lack of form"
Nice statement in his  interview, that he  can't push the  wattage as  last year.  He does  not understand  nor  do the coaches  know why.
 Here the problem.

 If you use wattage  and you make progress you are happy. You may have no real clue  why you make progress as all is based on wattage.  So what ever  you do  and you make progress is great  and  most likely the training you do is the reason of improvement of wattage. What they  do not know is, what  change in limiter and compensator or in other words,  what stimuli they created with their wattage  idea. What they as well do not know, whether the wattage zoning was always the same physiological zoning.
 BUT who cares as long you see progress.
  Now  one year later they  have a   small problem. They  do not know  why  the wattage training is not showing as of yet the progress they where hoping  for. They have still no cue  why but this time the result is frustrating as there is no progress.
 In fact they know exactly the same  as last year   meaning nothing , as they use wattage  which gives no feedback on physiological changes.
If they  add a physiological feedback to the wattage    they would easy  see, what  created the difference, as the same % wattage may trigger a very different physiological system.
 Depending what they  achieve in physiological changes last year ( but they do not know  what they changed )  this year the same wattage  may trigger a very different  stimulation.
 Example . Last year  was perhaps a respiratory  limitation.  This created a very different  reason  for   " fatigue "  than when there is a   muscular strength limitation.
 The way we  load  or  unload  has a  direct influence on what we stimulate.
  The time we load  and the duration and much more. Some very old physiological principles.
 In the past we  where hoping we see the predicted changes.  Today we  can see  live what actually happens  and understand the reactions much better. Here a very  simple example sent to us  from a great  big company. It is the same athlete  with 2  different  time related loads  but  same  load  at the end,  and you can see  that the change in duration of  each load  created a very different reaction. and therefor stimuli  on how   the athlete  had  to come up with ATP production.
 You can think   what may have changed.
 you see very clear  where they loaded  and than  had a break in between.  See internal questions and  feedback's2 test differetn MOXY information.jpg

The second  interesting reaction:
 Talansky , coming in  to the finish. Severely exhausted, leaning against the wall pushing his wattage button on his Garmin on the bike   and shaking his head.Far too late  no information really besides  it was not that good as he hoped for.
 What can he read out there after  the finish line, what feedback  does he is getting  from the wattage  and even from the HR  information.

Here  an example, from a cyclist  where we know  by what  intensity Wattage eh started to create a  outflow problem ( venous occlusion trend.
 This than will as well reflect in the ability of  preload    for SV ( stroke volume)  and as  such we  can possibly see a change in HR  . But only if  HR  is not already on its own limitation.
. Now  if we see this live in a TT  the athlete  can react in many different ways  to avoid this situation to persist too long  and has a  chance  to  create  a better outcome  first but  more important  has a  clear feedback on why  he  was not pushing the expected  Wattage level, as he simply  could not do it  due to  clear physiological reasons.
 Here  first the  example of the  load, where we see the  venous occlusion trend.
  than a  short part of the SV reaction which can be created due to venous occlusion trend  .

Here the drop in SV done  with a Physio flow  live.
drop of SV due to ve occl.jpg 

 Wattage  ( average  max  and min )  HR  average max  and min.    and  RPM  average  max  and min.
  What  does this tell him  ? What  can he  make on conclusions besides he lost a lot of time to the top  and he did not push as  much wattage.
 He has no clue  why, and where he may have messed up the  overall result. Perhaps in the steep climb, where he may  have pushed so hard that he created an occlusion and had to dig very deep  for O2  and than never ever was able anymore to get rid of the low tHb  due  to the muscle contraction.
 With a MOXY live feed  he could have  looked  at  trends   by changing  RPM  and or  even slightly body position.
 He was sitting really far in front in his saddle  and even a slightly   move back which  would have been possible with his  set up of the bike  may have change the  blood flow if that was one of the limiter  due to position.

One of the problems is always the compromise between aero position  and physiological reaction.So  out of the BOX thinking teams start now to add  more and more physiological information to their wind tunnel testing to find the optimal compromise.
On the other  side it  is fascinating to see how long it will take  to see  teams with multimillion $ budget investing  a small amount  ( much less than an aerowheel ) to start to learn the reactions of their athletes/ Traditional thinking is  hard to overcome.

Interesting in this example is also that in the second part of the final step you see the same venous occlusion trend, however it drops and then increases again until the step is over. He is obviously trying very hard to maintain performance but his muscles are fatiguing and he is having trouble maintaining contraction force. We see this when tHb drops again as venous outflow is again restored (at least somewhat), with this restoration it some metabolite accumulation is also released and we attempts again to maintain power, which you see in the final part of the step. Obviously, this is a game that will only work short term, in other words a survival attempt. Thoughts?

Nice  feedback  and when you look very carefully you can see that he  actually gives  up  before the   time is over.  THb    (occlusion outflow  before the SmO2  starts to react. I will show later once more a similar case  from a rower  with an occlusion ( strength limitation ) and  in that case we  actually even know , that in the last  load he was not able to maintain the wattage  and the drop in wattage is  exactly where he  fives up the arterial occlusion  and   we see the outflow  as well during the load..

In this  connection I will show you the difference between  all out  to reach an arterial occlusion  and  a  not all out load , where we see  a compensation  of O2  use form less involved muscles  and what this means  for the  overall performance.
 Key words.
 2 round Stanley cup. There Player  with a presents  of  over 3 min on the ice in a penalty killing  and all    show the same  " weakness" reaction to try to get the puck out of their zone.  ( Ca= Zdeno Chara, Bergeron  and Boyckuk all from the Boston Bruins against Montreal as well  on the other side  Emelin  Alex  and Beaulieu Nathan.
 Will show you some  MOXY information   what happens in this cases  and why we see this surprising weakness.

Okya here the first part . Rower with trends  of veneous occlsusion  and you can see in all three last loads  the struggle  to maintain load  and we know  form the wattage in this case, that he we dropping wattage  at the critical point , where we see the reduction of the occlusion effect.
. The question is, what  forced him to redcue the load ?
