Here are some more thoughts about your test results :
For all other readers , not as familiar yet with the FACT.
First part of the test is a classical step test with 3 /4 /5 min steps , depending on the individual HR respond. ( Very strong and older endurance athletes need more time to react with HR increase ,especially in the start phase. Remember Performance is set together as HR x SV X a-v O2 difference.
So at the beginning they still have the choice between HR increase or SV ( stroke volume ) increase.
Some coaches will use in this first part also the possibility to to a classical lactate test.
( If you choose this you have to be aware of the lactate dynamik and the timing. ) There is a clear difference in lactate value whether you choose 3 / 4 / 5 min steps or even harder if you use a classical conconi protocol.
So be aware and critical enough , why you do this in the first part.
At the end of the first part of the test. ( for high performance athletes all out , for beginner or people with certain risk factores you never go all out. ) you take in the classical FACT the first time the top lactate.
Again you have to understand , what this max. number in this test means.
The last part of the test with HR now as your guide you asses a) the lactate recovery
b) the performance recovery in watt or speed or other way of physical measures.
c) and you find your individual intensity ( we name it LBP for lactate balance point ) which is the individual intensity to be used , depending on your training philosophy to controle certain stimulus in your training plan.
There is much more you can do with LBP .
Now in the test from Kevins athlete.
Short summary :
First part of the test at the end.
HR 174 Watt 230 Lac 10.0
with the problem of pain on the one leg side.
The recovery line is identical with the first step test.
Ex. first part HR 133/ watt 130// HR 155 W 170
second part HR 135/ watt 135// HR 155 W 175
So same HR and physical performance even after 45 min . LBP by 150.
Explanation will follow later
I have to go because some people are waiting.
But why not start thinking , because this is a very interesting case and opens a lot of questions about subjects like :
HR drift ? classical lactate test, ?
1 leg biking ? more than just a coordination adventure.
How good is 1 leg pedaling anyway , hoe to improve this task.
Limiting factores for performance.
Fatigue ? metabolic ? coordinatiuon ? % of muscle involved / ?
See you later Juerg
