Been chatting to Juerg & Andrew about Keith's recovery lines :-
From Juerg :-
This green line. ( recovery line ) is actually a very good recovery . As you can see it will go back up to the performance line, meaning he actually even after a hard push can recovery back to the blue line.
Here's the idea of the recovery line :-
A recovery line , which converts back to the blue line is a good recovery information.
A green line who is below the blue line and never will cross over to the blue line but is getting closer is somewhat less good recovery .
A green line which is actually opening , bigger distance to the blue higher up is a sign of very low recovery stage in that specific test , due to different
reasons.
From Andrew :-
Juerg's point is well taken...if the green line eventually meets the blue line, then the person is able to "fully recover" fromm the original effort, showing "good" recovery (as both of those examples you gave demonstrated).
However, you and I are looking at it with a bit more detail, and actually examining the exact drop in wattage after the step test portion, and in this case, the recovery seems a little less than ideal.
As I mentioned yesterday, Paul has a good point...if you push an athlete very hard on the step test, they will have a bigger drop in the second portion.
And Juerg has a good point, that if the green line approaches the blue line, then that shows a good recovery as well.Â
My interpretation tried to identify a weakness that may be improved with training of the STF zone...and that is less of a drop in performance during the initial part of the recovery phase.
It is not clear whether this rider has "poor" recovery as I discussed previously, but it certainly shows there is an area of weakness that can be reassessed the next time around.
As you learn from us, you will realize even Juerg and I have different views on the same test. Sorry for that, it will cause some confusion for you I am sure. Easier for you to interpret the results having walked through the full test and seen with your own eyes what was happening.
