During the 5-1-5 below, the cyclists ThB drops in 4a/ 4b /5a while HR continues to rise.  Is this indicative of a stroke volume limitation or something else? 5-1-5 WB.png

Interesting data's  and  as  the reads will see I have  a very different  graph  combination  with one  equal  to the  one on the forum  but  2 more   NIRS feed backs.
 So need  some additional information's.  here the SmO2  graphs from    the  data's I got.

first SmO2 trends.

smo2 all 3.jpg 


you can see the  2  darker greens  have a similar trend and easy  to use  for  possible  zoning if somebody   like s zoning. Both  show  that the start load  has  nearly  the lowest   SmO2   values  as an indication off a  delivery limitation at the start  as  CO  and VE  are low  in case he did not  " warmed  up "   the interesting  section than is  at the end, where we know  he   has  " warmed  up "  he  still can not    utilize  lower.?
  now  we  do not have a  1  to 3 min start  calibration  so we do not know how the start was   from  rest   or  from  a  warm up.
 So let's  look at  HR  trends.

hr  smo2     vl.jpg 
A  start  or " resting  HR "  above  90  is possible but very high  so may be  he " warmed  up"
 Lets see the tHb trends  of all three  muscles   where we  do not know  which muscles  he really had a NIRS  device.
thb all 3.jpg 
Hmm  interesting is the middle  dark  brown , which belongs  to a  possible leg muscle  as we have in the  SmO2 trends show two  similar  which  could be  either left  and right  or  could be  VL  and  rectus  on the same side.  The light  green and   yellow brown on here is  a  upper body  delta muscle. most likely, but   there is some  interesting  reactions , when we   go back and  forth  from tHb and  SmO2.  There    is a   indication  that one leg  is  working very different  (  could be  an current injured leg or  an old  injury .   if  he used  2  legs  or if it is a   same leg  2  NIRS , than the   middle  brown  one could be a RF  and the dark   a VL. Will be fun to have some   info on placement  and if  left  right the wattage if  independent   wattage  was available.
 The  possible  upper body    delta muscle if it was there  is  not really a I  minimal  or non involved muscle  a sit looks like  but wee  can go closer   later.  In  a  first glance  without looking biased graphs  it  may be a utilization limitation  so  mitochondria  density  and  vascularisation  as a current limitation  with a cardiac   compensatory    part.
The compensation start in the last   full double set   look  at HR but  not very successful as you can see  so increase in HR did  not  created  at least in the one  muscle an increase in tHb  so   compression overruled  CO or  at least  did not increase  tHb.  The   middle brown tHb is interesting   to  repeat the  situation. Is the drop in  tHB   a  actual  systemic  vasoconstriction to shift  blood to a  more efficient    place  or is it a  muscular  compression  overload   against the   not sufficient  CO ?
 remember the  biased    picture  of a  non involved muscle  we had  from  Daniele's  D.  If  this  is  RF  on the same muscle  has the second  NIRS on  VL , than  we would have an example most likely of a   blood  flow shift  form the less efficient  RF  to the  much more efficient  VL . A  closer look at  Biased would  show  this idea   better. So let's  wait  and see.

I followed what my understanding of the 5-1-5 test protocol is - no warm up, a sensor on each VL and one on a deltoid.

Thanks  that is great. Does  this athlete  had  or  has a leg injury  currently or  an old  never   completely rehabed one. Nice  as well is (no critic  but  the idea of Ruud  to have a  3 min  start calibration  to settle  down   HR  and  respiration.
